How to Stop Emotional Eating & Get Healthy

It can be nearly impossible to achieve your health and fitness goals if you are overwhelmed by stress and other negative emotions. Millions of people, especially women fill their lives to the tipping point with obligations to family, friends, careers and more. When you spend all of your time focusing on the needs of others it’s easy to find yourself without enough time or energy to properly take care of yourself.

It doesn’t happen overnight but little by little responsibilities can pile up until you’re juggling so many balls that you fail to notice that diet and exercise have become much less of a priority. A few pounds here and there can add up quickly before you finally realize that the emotional toll of everyday life is has manifested into a physical problem.

If you are like many Americans, you may turn to food for comfort or distraction from stress or other destructive emotions. This can easily turn into a vicious cycle of overeating followed by fasting out of guilt for doing so.

If you struggle with emotional eating and want to get back on track toward living a healthier lifestyle you can start by asking yourself one important question each time you turn to food.

Are you really hungry?

You may have to retrain your brain in order to learn how to have a healthy relationship with food. In order to do this you have to recognize the difference between impulse eating and eating for nutrition. Each time you reach for a snack, try to make a habit of taking a moment to notice when and why you are eating. Backtrack through your day and try to identify any emotional triggers that you may be mistaking for hunger.

Everyone has a different emotional response when it comes to stress, anger or sadness and you may not even realize what is triggering you to overeat. Consider what is happening and how you are feeling when you turn to food. You may be responding to stress, trying to fill a void or looking for comfort in some small form of momentary satisfaction. Listen to your body and take note of your physical and emotional state.

Identify and consider your feelings but don’t go too far and over analyze each moment to your life. The idea here is to become more in tune with yourself and not to be overly critical of every move you make. Maybe you had a hard day at work or you’re consumed with family drama. Make an effort to actually feel your emotions and process them rather than trying to distract yourself with food. You may come to realize that what you were feeling was not hunger after all. Once you’re able to see the patterns and triggers that are leading you to over eat you can learn to make the necessary changes to avoid following the same path in the future.

Tips to help you stay on track

Reduce Stress
Less stress equals less emotional eating. Negative emotions can take both a mental and physical toll. Not only can stress trigger overeating but it can also cause fatigue and exhaustion. If you can eliminate unnecessary negativity in your life you are more likely to stick to your diet and have the energy to exercise on a regular basis.

Be Realistic
Make a plan and set goals that are conducive to your lifestyle and within your reach. If you set yourself up for failure with unreasonable expectations you may become quickly discouraged. Start by committing to a regular exercise schedule or losing that first 5 pounds and keep track of your progress. Achieving small milestones can help you to stay motivate to get healthy.

Don’t Starve Yourself
Cutting calories and eating better in no way means that you should go hungry all the time. Too few calories or not eating all together can actually lower your metabolism and make it harder to lose weight. If you really are hungry go for more healthy options and practice portion control to avoid overeating.

By addressing your emotions and reducing your stress level you can uncover and alleviate deeper issues that may be sabotaging your attempts to live a healthier lifestyle. It can be very difficult to be consistent with your diet and exercise if you are constantly overwhelmed with negative emotions. By discovering why you’re overeating in the first place and building a more healthy relationship with food you will be better equipped to start getting in shape and losing that unwanted weight.

5 Rules Fit People Follow

That friend you know that is the same size they were in college or that coworker that makes you jealous at the beach doesn’t stay fit by magic. The majority of people that are able to stay in great shape follow a few basic rules to keep them on the right track.

No Excuses

If you really want to get in shape and be satisfied with what you see every time you look in the mirror then you have to be real with yourself. It’s time to stop with the excuses. Most people are guilty of making a New Year’s resolution they don’t keep, putting off the gym until next week, saying they will start their diet after the holidays or that they’re just too busy to make time for working out. The list of excuses can go on and on but the longer you wait the further you get from the person you want to be.

If you want to be in better shape, get healthy or lose some unwanted weight, you have to make the decision that you are going to do it. Don’t let the lazy person inside your head let you sit on the couch watching Netflix and eating ice cream one more night. You can accomplish your fitness goals if you just make a commitment and start putting in work today.

Set Goals

Having goals really does work. Give yourself a milestone to reach for and a deadline to get there. Maybe it’s losing 10 pounds by your birthday, getting fit before swimsuit season or training for that marathon you always wanted to run. Having something to aim for can help to keep you motivated.

Mark the date on the calendar and check up on yourself each week to track your success. As you start to see some progress it will give you more drive and confidence to accomplish what you set out to achieve.

Prep for Success

Healthy eating and regular exercise doesn’t happen by accident so set yourself up for success.

Working out alone isn’t enough to produce noticeable results in your body. If you are over eating or simply not eating right then it’s almost imposable to lose weight. Make it easier on yourself and keep healthy food choices on hand at home, work and even in your car. It can be hard to resist temptation when you are busy or hungry and you are far more likely to choose something good for you if it’s readily available.

The same concept can be applied to your workout regimen. Sometimes it can be hard to roll out of bed early to go to the gym or convince yourself to exercise after working all day. You can make some smart choices and do some simple preparation to help yourself stay on track. Start with a good night sleep or by having your workout cloths ready and laid out for the morning. A little preparation can go a long way toward helping you meet your goals.

Stick With It

If you want to get in shape and stay there then it’s important to be consistent. You can’t lose weight by eating salad all week and binging on the weekend or working out 5 days a week and then taking a month off. The people you envy at the gym that have the body you would love to have don’t look that way without sticking to their diet and exercise routine. If you want to get into peak physical condition and be healthier overall then you have to make good lifestyle choices each and every day.

It can be hard sometimes to go out for that run when it’s raining and you’re still sore from the day before or to stick with your yogurt when a coworker brings in homemade cookies for everyone in the office, but stay strong. You don’t want to undo all of your hard work for one brief moment of satisfaction.

Keep Pushing

If you want to be in great shape then don’t settle at your first goal or stop when you reach a plateau. You can be that person at the gym that the newbies are looking at with envy if you keep pushing yourself. If the mile you starting out running is a breeze now then make it two or if you lost the first 10 pounds you wanted to get rid of go for five more if that is a healthy goal for you. Being fit isn’t supposed to be easy. You have to work at it and keep pushing to get results.

Nobody ever said staying fit was easy. And if they did, they were lying. With a little hard work and dedication, you’ll be looking in the mirror at your ideal self in no time. Just remember to stay motivated, stay motivated and stay focused. The body you’re working for is right behind you.

8 Foods to Boost Your Daily Water Intake

We’ve all heard the old saying, “drink 8 glasses of water every day for better health”. Water is an essential part of staying healthy. It keeps our internal organs healthy and our skin looking young. While this advice has been around for years, most people still find it hard to get enough water in their diet.

It may not seem like a difficult concept but sometimes it’s just hard to remember or keep track of. With jobs, kids and a variety of other obligations, it can be difficult to find time to drink those 8-ounce glasses every day. If you’re like most of us, you’ll be happy to know that there is still hope for you. What if I told you that you can get some of that water from the food you eat? Well it’s true and here’s how you do it.

Watermelon
Water: 91.5%

This one is pretty much a given. After all, it has the word right in the name. Other than its water content, this delicious fruit is also high in the powerful cancer-fighting antioxidant Lycopene, which has also been shown to help prevent heart disease. Watermelon is a summer staple that makes it a perfect snack on its own or as an addition to a fruit salad. You can even freeze cubed watermelon pieces for a sweet ice substitute in a glass of water.

Cucumbers
Water: 96.7%

Cucumbers are a delicious and healthy vegetable that are perfect for those hot summer days. They can be eaten by themselves fresh from the garden or added to a sandwich or salad. Some people prefer to sprinkle a little salt on their cucumbers. Small amounts of salt can actually help your body hydrate itself. Just be careful not to use too much since large amounts of salt can cause an unhealthy level of water retention.

Iceberg Lettuce
Water: 95.6%
Iceberg lettuce tends to get a bad reputation when it comes to nutrition. Many people tend to opt for darker varieties since they have higher levels of fiber and various nutrients. When you’re trying to increase your water intake however, iceberg is the king of lettuce. Its high water content makes it a perfect crunchy addition to any salad or wrap.

Spinach
Water: 91.4%

If you’re looking for a more nutritious substitute for Iceberg lettuce, you’ve found it with spinach. While its water content may not be quite as high, it makes up for it with its high levels of fiber, potassium and free radical fighting antioxidants. You can replace lettuce entirely or even better, combine the two for a nutritious water-rich powerhouse.

Bell Peppers
Water: 93.9%

Peppers are a great tasting snack that is not only full of water but powerful antioxidants as well. While all varieties of bell peppers contain a high amount of water, green peppers lead the pack. Peppers make a flavorful snack on their own or a great addition to any sandwich or salad.

Celery
Water: 95.4%

You’ve probably heard the old saying about celery having “negative calories”. While this isn’t exactly true, each stalk does come in at only 6 calories. Add that to its high fiber content and vitamins C, A and K, celery is an excellent vegetable for additional water intake. Top those stalks with some peanut butter for a tasty snack that is not only high in water content but a healthy way to curb your appetite.

Tomatoes
Water: 94.5%

Tomatoes are great for getting some extra water because they come in so many varieties and can be eaten in so many ways. While tomatoes can be sliced or chopped for a juicy addition to a salad, smaller varieties like cherry tomatoes are delicious on their own. They make a perfect bite-sized snack any time of the day.

Strawberries
Water: 91%

There’s no denying that strawberries are delicious. If you’ve ever eaten a strawberry straight from the garden on a warm summer day, you know exactly what I’m talking about. The juicy explosion of flavor makes strawberries an irresistible snack that is both hydrating and healthy. Their high levels of carbohydrates and protein make them a refreshing snack to get rehydrated after a tough workout. Eat them by themselves or as a tasty addition to yogurt or a smoothie.


By no means should you use these foods as an excuse to stop drinking water entirely. You should still try to drink a good amount of water throughout the day, especially on those hot summer days. It would be pretty difficult to get all of the water you need through food alone. As a good rule of thumb, you should drink half your body weight in water per day. Simply take your body weight, divide by two and that is the number of ounces you need to drink, and that is only the minimum so stay healthy with your water.

Exercise Can’t Overcome a Poor Diet


It’s an all too common misconception that you can lose weight and stay healthy just by exercising regularly. The reality is that exercise alone is not enough to overcome a poor diet.

The Myth

Many Americans believe that if you exercise on a regular basis you can eat whatever you want and still remain healthy. This myth has been developed over decades of thinking that being inactive results in obesity. In recent years, evidence has come to light suggesting that this isn’t the whole truth.

We commonly associate obesity with lack of exercise, but studies now show that inactivity is more of a side effect of obesity than a cause. This means that the majority of people don’t become overweight solely because of not exercising. In fact, it’s more common that people stop being active because they are overweight.

That may sound like a catch-22 but research shows that a healthy diet has more to do with your general health and ability to maintain a healthy weight than exercise does.
To be clear, that doesn’t mean that you shouldn’t exercise. Regular exercise results in numerous health benefits such as improved cardiovascular health. The message you should take away from this research is that we need to relearn what we think we know about being healthy.

Sugar Overload

In order to be healthy and lose weight more effectively, you need to cut down on your intake of sugar and carbohydrates. When it comes to healthy eating, there is a list of excuses a mile long for why it is too hard or too expensive. If you’re interested in living a long and healthy life, you need to stop procrastinating and start making better decisions about what you put into your body.

In this fast paced world full of fast food, the average person eats far more than the recommended daily value of calories. If, like many Americans, you visit the occasional drive through for a quick and easy meal on your lunch break you may be consuming your daily caloric intake in one sitting. A chocolate chip frappe from McDonalds boasts a whopping 66 grams of sugar and 520 calories. Add a steak and cheese bagel to that and you get another 670 calories and 35 grams of fat.

Why You Can’t Lose Weight with Exercise Alone

According to traditional thinking all you need to do to lose weight is burn more calories than you consume. That may sound simple in theory, but in real life, it’s much more difficult than you may think.

Many people really believe that they don’t have to worry about counting calories because they exercise every day; this is simply not the case. Exercise is in no way a free pass to eat anything you want. If you want to burn off that fast food cheeseburger you had for lunch you’re going to have to work out for over an hour. If you are making unhealthy food choices all day, the logistics just don’t add up. No amount of exercise can overcome the damage done be a poor diet.

How to Be Healthy and Lose Weight

If your goal is to lose weight and improve your overall health, then you need to eat a balanced diet in conjunction with your workout routine. Reducing your intake of foods that are high in sugar and carbohydrates is just as important as pulling yourself up off the couch.
The key is to set yourself up for success. Keeping healthy and nutritious foods on hand can help you resist the temptation you face when you go to the store hungry. Taking a little time out of your weekend to prep meals for the coming week can make it easier to say no to fast food on your lunch break.

Initially it will take a little will power to drop the sweets in favor of a healthy diet but each time you choose an apple over a candy bar or bag of chips makes the next time that much easier. If you want to reap the rewards of all your hard work at the gym the best way to shed those unwanted pounds is to start with the right diet.

How to Achieve Your Nutrition Goals

How to Achieve Your Nutrition Goals

With summer around the corner, the thought of bathing suits has a lot of people scrambling to get in shape. The great news is that it’s a lot easier than you might think to develop great habits that will keep you healthy this summer and many more to come.

One of the biggest obstacles we all face when trying to stay healthy are the bad habits we develop. With all the major decisions we have to make each day about our jobs and family, we often allow ourselves to function on autopilot when it comes to the more mundane aspects of our lives, such as eating and exercise.

Luckily there are some simple steps you can take that will make your life easier and allow you to focus on those important tasks at hand.


1. Pre-cut your vegetables

We all know how important fruits and vegetables are to our health. The problem is that they can be so time consuming to prepare. While a healthy salad might sound like a good idea for lunch, the time it takes to cut up all those veggies often drives us to faster, less healthy options.

By chopping up your vegetables ahead of time, you’ll be much more likely to make that healthy snack. One option to make this easier is to cut up all of your veggies the day you buy them and store them in containers. That way when you are hungry, you can just reach into the refrigerator and throw together a healthy meal with very little effort. You can do this for sandwiches, salads and all sorts of other quick and easy meals.

2. Bring out the fruits and vegetables

Let’s face it, a lot of us are grazers. While we may have the best intensions of eating healthy, it’s easy to fill up on small, fattening snacks throughout the day. Grazing all day may seem harmless, but it adds up quickly and becomes an unhealthy habit.

You can turn that bad habit into a good one by leaving fruits and vegetables out in visible places around your house. Even if you’re busy running in 100 different directions, you’ll be more likely to grab a handful of grapes, strawberries or carrots when you see them. These small snacks will satisfy your appetite while filling you up with healthy produce rather than junk food.

3. Have a back-up

We all know that a home cooked meal can be much healthier than take-out or processed foods. Cooking allows you to control what goes into your food and monitor your intake. The problem is that every extra step adds more work and takes more time out of your already busy day. To stay on track, you want to make things as easy as possible.

One way you can do that is to have a back-up of all of your favorite kitchen tools easily accessible in your kitchen. That way, if one of them is dirty you don’t have to take time to clean it before starting dinner. You just use your back-up and throw the dirty one in the dishwasher.

A must have back-up tool is a crock pot. Just throw in a bunch of healthy foods and walk away. What’s easier than that?

4. Keep your table clutter-free

Sure, we all find ourselves eating in front of the TV once in a while. After a long day at work, sometimes you just want to relax and watch your favorite shows. The problem is that it can quickly become a habit. Eating in front of the TV can cause you to become unaware of how much food you’re consuming, which definitely isn’t healthy.

By keeping your table free of clutter, you’ll always have a designated place to eat that you don’t have to take the time to clear beforehand. You’ll be more mindful of what you’re eating and it requires no additional effort on your part.

Besides, you’ll be allowing yourself to enjoy time with family and friends instead of tuning out in front of the television.

5. Arrange your kitchen for success

Sometimes you have to trick yourself a little to achieve your goals. This last tip is something that grocery stores have put a lot of research into. They’ve found that when premium items are placed at eye level and are easiest to reach, customers are more likely to buy them.
You can use this same trick in your kitchen. Place items you use most for healthy cooking in locations that are easy to access. That way you’ll be more likely to grab them. You can do the same thing with healthy snacks like bananas and apples. This trick may take a little effort initially, but once your kitchen is organized to work with you instead of against you your life becomes a whole lot easier.


Healthy living can take a lot of effort and willpower, especially if it’s not something you’re used to. Luckily by making these five small changes to your routine, you’ll make achieving your goals much easier. Over time, these tips will become habits and your healthy self will be relaxing in the sun instead of scrambling to get in shape.

Glutamine

 Great article written by my good friend, Lucho Crisalle

Glutamine is the most abundant amino acid in the body, making up 60 percent of the amino acids in skeletal muscle. It is a true super nutrient! It increases growth hormone levels, encourages lean body mass, and promotes muscle growth. It supports brain function, immunity and intestinal cells. Athletes and bodybuilders choose Glutamine as it helps buffer lactic acid, which tires muscles and reduces performance. Those training for endurance sports often take Glutamine to reduce cramps caused through repetitive motion. Plus, glutamine actually helps you store muscle glycogen, the primary fuel source for intense exercise.  
And since this amino acid has a mildly sweet taste, and is readily absorbed from the intestinal tract, supplementation is easy and pleasant.
In a nutshell, the primary benefits of L-Glutamine have been found to be: 
  • prevention of muscle break down and support in fat loss (from increased muscle as well as increased production of human growth hormone) 
  • support of enterocytes (intestinal lining cells) through which all nutrients are absorbed
  • improved or increased immune system
  • clarity of thought and better muscle contractions as it is the amino acid found in highest concentration in spinal and cerebral fluid. 
So, what is L-Glutamine?
L-Glutamine is the most abundant “free” amino acid in the body, but it is considered a “non-essential amino acid” since it can be synthesized (made) in the body from glutamate. However, scientists have classified glutamine as a “conditionally essential” amino acid, because under certain conditions (such as severe stress), glutamine may be needed in much higher amounts.  Additionally, glutamine has been found in higher concentrations than other amino acids in vital tissues including the brain, intestinal mucosa cells, immune cells, and in skeletal and smooth muscle.
Technically, Glutamine acts as a nitrogen shuttle by picking up and dropping off nitrogen around the body.  Nitrogen is an essential component of DNA (the genetic material of life) and vital for muscle building. Glutamine also converts to alpha-ketoglutarate, an essential nutrient to create energy via the Krebs cycle.  
Safety & Side Effects 
More and more research continues to show significant results with the supplementation of L-Glutamine without negative side effects even up to 60g per day for the ultra-intense training athlete.
Recommended Dosing
L-Glutamine is recommended for intense training athletes, those subject to immune toxins or weak immune systems, and post surgery and irritable bowel syndrome (IBS) patients.  Normal dosing ranges from 2g per day up to 60g per day. Optimal dosing is 5-10g per day in divided doses.  This is a perfect supplement for flu and cold season as well as year round.  
For increased GH release, take 10g L-Glutamine upon waking on an empty stomach, as well as before bed. It is also highly recommended to be taken pre and post workout.
With all the benefits glutamine offers, and available at a more than reasonable price, it only makes sense to make this one of your primary supplements.
Now you can build up your immune system and enhance your physical performance, all in one super supplement!
MORE INFORMATION:
Glutamine and Skeletal Muscle
In muscle, the concentration of free glutamine appears to influence whether muscle will break down (low glutamine content) or build (high glutamine content). Athletes suffering from continuous fatigue have shown to have decreased blood glutamine concentrations that persist for extended periods of time. These decreased concentrations may hinder immune health and lead to slower recovery times following exercise and physical stress. Subjects supplementing with oral glutamine show elevated plasma concentrations of both glutamine and growth hormone, suggesting glutamine’s potential benefit in terms of body composition.
Additional Benefits of L-Glutamine
Glutamine is also a major contributor to proper functioning of the intestines. By serving as an energy source for these highly active cells, many studies have demonstrated the critical role of glutamine as the predominant fuel for intestinal epithelium and its vital action in maintaining intestinal structure and function in stress-related situations.
Patients recovering from strenuous physical activity have an increased demand for glutamine. This is probably the result of increased use by the immune system and the decreased integrity of the traumatized tissue. Following stressful physical demand, amino acids become vital for the healing process. Glutamine has proven to be essential during this time because the demand may exceed that which can be obtained from muscle stores.  A study at the Geisinger Medical Center noted that increased muscle breakdown following extreme physical activity was in part due to glutamine deficiency. From their observations the researchers concluded that glutamine supplementation will prevent muscle breakdown and enhance the healing process. Lastly, there is evidence showing glutamine to be helpful for alcohol addiction. In an early study, alcohol consumption was curbed slightly when 1,000mg of glutamine was administered orally.
Support for Immune Health
It is well understood that immune health is dependent on macrophages and lymphocytes (a type of white blood cells). Glutamine levels are very high in white blood cells, and in experimental cell cultures, lymphocytes were less efficient when glutamine was reduced. When glutamine was added to the culture medium, lymphocyte reproduction significantly rebounded to a normal rate. A further study showed that lowered glutamine concentrations reduced adequate immune health underscoring the importance of supplementation for individuals whose immune status is stressed by heavy physical activity. 
Support for Neurological Health
Because glutamine is one of the most abundant amino acids in cerebrospinal fluid, it readily enters the brain where it can serve as a precursor to the neurotransmitter gamma-aminobutyric acid (GABA). GABA and serotonin are vital neurotransmitters with various functions including enhanced sense of well being and calmness. In one study performed at St. Joseph’s Hospital in Phoenix, researchers showed that glutamine supplementation helped to maintain amino-acid concentration in brain tissue, increased the uptake of tryptophan and enhanced synthesis of serotonin.

How to Increase your Metabolism Naturally



The single most important thing to properly losing weight and increasing your energy levels is your metabolism, and this function tends to get a lot of attention these days. Your metabolism takes the nutrients you have consumed and converts them into energy, which is commonly referred to as “burning calories”. This energy producing process allows your body to prevent further weight gain. However, each person’s metabolism is different because of genetics, age, and gender, but do not let this prevent you from taking measures into your own hands that increase your metabolism naturally.

Strength Training to Build Lean Muscle
Strength training is often misconstrued as being the same as muscle bulking, but they have different intentions. Muscle bulking is where a person follows a high calorie diet with plenty of weight training. However, strength-training focuses on building your strength through lean muscle gains, which plays a role in your metabolism and overall health.
The reason is because muscle requires calories to exist and maintain themselves. Research shows that muscle requires 6 calories per pound a day for sustainment, while fat only requires 2 calories per pound. Your resting metabolic rate is constantly running even while you are asleep, so the muscle makes a difference in keeping the unwanted weight from sticking around.
During training, and the 2-3 hours afterwards, your body’s metabolism is at an all-time high depending on the intensity of your workout. The harder you train and elevate your heart rate, the faster your metabolism pumps away and burns calories. Increase your intensity to reap the max benefits, but do not over train and injure yourself.

Stay Hydrate with Water
Your body requires the daily amount necessary in order for you to simply survive with a healthy body, and your metabolism needs this water in order to process the calories being taken in. Studies have shown that an average adult who drank up to 8 (8 ounce) bottles of water has seen a higher number of calories burned opposed to those who drank only 4 (8 ounce) bottles. Even being the slightest bit dehydrated can slow your metabolism down, so drink water throughout the day and prior to a meal. Fruits and veggies are also good choices for hydrating since they naturally have water in them.

Moderate Consumption of Spicy Foods and Caffeine
Spicy foods have a way with your body, and are capable of increasing your metabolism naturally with the use of thermogenic properties (cayenne, chili powder and cinnamon) Supplements used for weight loss repeatedly contain ingredients such as chili extract, and the reason is because this kind of food heats your body up, which causes your metabolism to increase for a short period of time. So that warm sensation you have been feeling from eating spicy foods is actually your body starting to burn more calories.
Caffeine from green tea and black coffee actually has great benefits when consumed moderately. Caffeine naturally increases your energy levels by making your heart pump blood faster, which as mentioned leads to a heightened state in your metabolism. Both drinks are easy to consume, but do not excessively drink too many cups a day or the outcome is not just an increased metabolism.
While you cannot overcome things like aging or genetics, you can and boost your metabolism and have a healthy lifestyle. It just depends on how you choose to diet and exercise.
