Empty Calories Working Against Progress by Brandon Gremillion

[Brandon Gremillion is a student at the University of Mount Olive majoring in Exercise Science. He is currently an Athletic Development Intern at Athletic Lab.] Empty calories refer to foods high in calories, but low in nutrients. The term empty relates to added sugars and solid fats that are found in many processed foods which offer no micronutrients (Grosvenor & Smolin, 2015). Micronutrients are all of the essential vitamins and minerals we must consume on a daily basis because they are not synthesized in our bodies. A majority of the food found in America is processed. The more processed something is the less nutritious it usually is. Identifying processed food is not difficult. If it does not come from and animal or grows from the Earth then it is processed. If the food is not in its naturally existing state before it is prepped for a meal then it is most likely processed. Many people have an understanding of macronutrients (carbs, fats, and protein), but lack knowledge of the micronutrients. Vitamins are organic compounds that regulate body processes necessary for growth, reproduction, and maintenance of health (Ferraro & Steele, 2004). Vitamins are either water soluble (B vitamins and vitamin C) or fat soluble (vitamins A, D, E, K). The vitamins split up into sub groups to help generalize how the vitamins are absorbed, transported, excreted, and stored in the body (Grosvenor & Smolin, 2015) Water soluble vitamins are not stored to a great extent and rapidly deplete from the body (Grosvenor & Smolin, 2015). We must eat these vitamins regularly to avoid becoming deficient. The B vitamins are directly involved in transferring the energy in carbs, fats, and protein to Adenosine triphosphate (ATP) (Ferraro & [...]

The efficacy of intermitting fasting for weight loss by Chris Graham

[Chris Graham is a graduate student at The University of Texas at Tyler and is currently studying Kinesiology. He is currently a sport performance intern at Athletic Lab.] Intermittent fasting (IF) has been popularized in the recent years as a method of weight loss and there are many people who claim to have found success using this method. What exactly is IF, and is it an effective and sustainable method to achieve weight loss? First off, IF is the practice of not consuming food for an extended period of time (typically 12+ hours) which is called your fasting time. This is followed by a fast time where you can eat ad libitum. There are a variety of ways to accomplish this, but one of the most common is to alternate fast and feast days for an extended period (3-8 weeks). In a recent review comparing IF and caloric restriction in overweight and obese individuals, Varaday (2011) found that both diets had similar results on weight loss 4-8% from IF and 5-8% from caloric restriction. However, in the IF studies 10% of the weight loss was from fat free mass compared to 25% in the caloric restriction studies (Varaday, p. e599). This retention of more fat free mass compared to regular caloric restriction proved to be more beneficial in improving body composition, and may be a result of average HGH increases of 1,300% in women, and nearly 2,000% in men during a 24-hour fast (Intermountain Medical Center, 2011). This spike of HGH protects your current muscle mass while also stimulating the breakdown of fat cells. In a separate study examining the effects of IF in resistance trained individuals, one group was assigned a time restricted feeding [...]

A Practical Look at HMB Supplementation Research and Application by Earl Wilcox

[This is a guest blog by Earl Wilcox. Earl is a graduate from the Kinesiology program at the University of North Carolina at Greensboro. Earl currently possesses his CSCS from the NSCA and is an Applied Sports Science Intern at Athletic Lab.] Beta-hydroxy-beta-methylbutyrate (HMB) is a supplement that is a byproduct of the breakdown of the amino acid Leucine, which plays a vital role in the regulation of protein synthesis. It is because of this relationship that HMB could help improve performance. There is no magic bullet when it comes to supplements and HMB is no different. However, there are a few circumstances in which it could assist athletes in performing better. Why would you need a supplement like HMB if Leucine is readily available in foods rich in protein, specifically animal proteins? The reason is that during the breakdown of Leucine, only 5% is converted into HMB (Wilson et al., 2013). To reach the recommended daily dosage of 3 grams of HMB, one would have to consume 600 grams of protein to reach this dosage, which would be the equivalent of 5.5 pounds (88 ounces) of steak throughout the day. There is a restaurant in Texas that will let you eat for free if you can eat their entire 72 oz. steak dinner in one hour. Pictured below is the size of their steak; now imagine having to add an additional pound to that steak. (Picture of steak) While this certainly might be a delicious option for some, it would not be sustainable from a caloric intake standpoint because that amount of steak would have a caloric price tag just shy of 6,800 calories! This would not align with our goal of increasing athletic [...]

Avoid Fad Diets and Build Habits by Zach Rosstich

[This is a guest blog by Zach Rossitch. Zach is a graduate of the University of North Carolina at Chapel Hill and the National Personal Training Institute. He is also a part of the Coaching Mentorship Program at Athletic Lab.] Fad diets are very popular throughout the United States. There is constantly new "research" that comes out claiming that eating this is better than eating that, or eliminating this from your diet will make you lose weight fast. The more commonly heard of diets are macronutrient-focused diets such as low-carb or low-fat, food elimination-focused diets such as the Paleo diet, time-focused diets such as intermittent fasting, and food group-focused diets such as the Mediterranean diet (1). Even with just this short list of examples, it can be overwhelming for people when trying to decide which one to choose. So, which diet is the best for weight loss? The short answer is: there is no universally optimal diet to follow (1). The human body is so complex, and everyone is made differently and leads different lifestyles. Due to this, each individual is going to have slightly different needs when it comes to their diet. As humans, we naturally desire immediate results. Therefore, these diet gurus take advantage of this characteristic and invent a unique dietary plan that supposedly helps you lose a lot weight in a short period of time. It sounds great and a lot of times people do see significant weight loss within the first couple of weeks, but unfortunately, the majority of these fad diets are not sustainable. They are usually nutritionally unbalanced and work quickly by significantly cutting back on one of the three macronutrients in attempt to create a caloric deficit [...]
