In this session from the 2015 Personal Trainers Conference, dietitian Dawn Weatherwax explains how the health of the digestive system affects overall health. Learn how gastrointestinal health impacts fat loss and muscle gain, the signs and symptoms of poor gut health, and foods and supplements that have been shown to have a positive impact on gut integrity.

In this session from the 2015 NSCA Personal Trainers Conference, dietitian Dawn Weatherwax discusses how knowing a client’s body composition can help in setting nutrition and training guidelines. Weatherwax reviews nutrient timing; eating the right mix of carbs, fats, and proteins at the right times; and other important facts that may impact a client’s outcomes.

In this session from the NSCA’s 2016 Personal Trainers Conference, Marie Spano discusses the top five questions clients have about nutrition, weight loss, and getting fit and healthy. Learn to teach your clients how they can feel an immediate difference, the most effective strategies for losing weight and keeping it off, and the health implications of popular diets.

Although it may be possible to increase skeletal muscle levels of carnitine by combining it with relatively large amounts of carbohydrates repeatedly throughout the day, or by taking it with choline, there is limited data that shows that carnitine is a fat-burner that results in significant reductions in fat mass.

Women are at greater risk for body dissatisfaction and disordered eating than men with the goal of achieving top sport performance and physical condition. It is important to provide proper referrals for female athletes requiring nutritional guidance to improve their body composition or with a need to lose weight.

As the prevalence of disordered eating in sport continues to increase, sports dietitians and all medical personnel must learn to identify it properly and follow evidence-based practice, including sound judgment, when treating athletes with these issues.

Before sports nutritionists and coaches begin prescribing unconventional eating recommendations to athletes, it is important to consider the scientific evidence supporting a low-carbohydrate diet for boosting athletic performance.

This article is a personal perspective of creating and providing a fitness assessment and resistance training program from scratch to a large law enforcement organization.

Time-restricted eating (TRE) is an application of intermittent fasting where an individual consumes their calories in a specific eating window (e.g., 8 hours) followed by a prolonged fasting window (e.g., 16 hours). Several randomized controlled trials have analyzed the combined effect of resistance training (RT) and TRE on physical adaptations, including fat mass (FM) loss, fat-free mass (FFM) retention, hypertrophy, local muscular endurance, power, and strength. In this mini review, we highlight the methodology and results from these studies and conclude by providing practical application suggestions for fitness professionals striving to maximize RT + TRE with their clientele. Generally, RT + TRE leads to positive body composition changes, including FM loss and FFM retention, which culminates in improved body fat percentage. Similarly, RT + TRE consistently stimulates positive neuromuscular adaptations, such as increased hypertrophy, local muscular endurance, power, and strength. When positive changes are not observed, and when safely implemented, RT + TRE rarely confers negative effects on the abovementioned adaptations. In short, RT + TRE may be a beneficial dietary and exercise strategy to improve body composition and muscular fitness. However, there are several caveats for practitioners to consider, which are discussed at length in this article.
