Diets moderately higher in protein and slightly lower in carbohydrate may be beneficial when it comes to weight loss and improving body composition, as well as for sport performance.

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.

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.

This article will explain the interference effect and provide a rationale for why low-intensity steady-state (LISS) cardiovascular training may be a useful tool for those interested in improving their body composition.

Learn how diet and strength training in the absence of aerobic exercise can be used to improve body composition through simultaneous fat loss and muscle gain. In this session from the NSCA’s 2016 Personal Trainers Conference, Todd Miller demonstrates how to use body composition and metabolism measurements along with popular food tracking apps and activity monitors to design individualized diet and exercise strategies.

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.

The extent to which a special operator’s training schedule can be planned in advance is often limited due to their unpredictable operational demands. However, there may be opportunities to plan for specific training during certain periods.

This excerpt explains the importance of optimal nutritional strategies in conjunction with good sleep hygiene and how that can help mitigate damaging effects of deployment and shift work on performance.

This book excerpt from Developing Endurance goes over nutritional strategies for pre-competition and during competition phases to maximize performance.

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.
