Stephanie Howe, PhD, a CTS Pro Coach and nutritionist, discusses weight loss for performance and macronutrient breakdown. They also talk about the challenges of maintaining sustainable diets, the rebound effect after diets, and the importance of enjoying food. The podcast explores the complexities of weight loss for athletes, skinfold analysis, smart scale accuracy, different approaches to weight loss, and how the menstrual cycle affects female athletes. It emphasizes the significance of fueling and body weight for ultrarunners.
For athletes aiming to optimize their body composition for performance, it is recommended to start as far away from the race as possible, making changes to increase protein intake and slightly decrease carbohydrate intake while ensuring adequate fuel for training.
For individuals aiming for general body recomposition, the process may be simpler and less focused on high-performance outcomes, focusing on making better food choices and increasing training volume, allowing for natural weight loss to occur as individuals become more active and make healthier food choices.

Optimizing Body Composition for Performance
For athletes aiming to optimize their body composition for performance, it is recommended to start as far away from the race as possible. This allows time for nutrition changes to take effect and for training volume to remain lower during the weight loss process. Initially, athletes log their food intake for 5-7 days to analyze their average caloric intake and macronutrient distribution. Changes are made to increase protein intake and slightly decrease carbohydrate intake while ensuring adequate fuel for training. Check-ins occur every 4-6 weeks to assess progress and adjust goals and strategies accordingly. Progress may not be linear, with initial changes occurring more quickly followed by a slower rate of change. Accountability and regular assessments help athletes stay on track and make necessary adjustments.
General Recomposition Goals
For individuals aiming for general body recomposition, the process may be simpler and less focused on high-performance outcomes. After a period of weight gain or less healthy food choices, individuals can start by making better food choices and increasing training volume. The focus is on eating a little better and training a little more, rather than meticulously tracking macronutrient composition. This approach allows for natural weight loss to occur as individuals become more active and make healthier food choices. The emphasis is on low hanging fruit, making easy changes to the diet and lifestyle that can lead to significant improvements in body composition over a couple of months.
The importance of sustainability in nutrition
The podcast emphasizes the need for sustainable eating habits rather than focusing on specific superfoods or restrictive diets. The speaker highlights that sustainable nutrition is more about overall calorie and macronutrient composition rather than specific food choices. They suggest that extreme diets or cutting out entire food groups are not sustainable in the long run and often lead to rebound weight gain. The focus should be on achieving a healthy body composition and optimizing overall health rather than chasing a perfect diet or specific foods.
Considering energy availability for optimal performance
The podcast discusses the significance of energy availability and its impact on performance and overall health. The speaker mentions that athletes should enter stressful events, such as training camps or long-distance races, with sufficient energy stores and body weight. They caution against going into such events under-fueled or underweight, as it can lead to poor performance and negatively affect the body. The emphasis is on maintaining balance and ensuring athletes are fueled adequately to handle the stress and demands of their chosen activity, rather than obsessing over weight or specific body composition goals.

(25:43) Weight loss for performance: nutrition for performance and nutrition for weight loss are at odds, keep training volume low, start making changes well before your goal race, hormonal effects of undereating and sex differences
(37:23) Macronutrient breakdown: dependant on goals, maintaining lean muscle mass, increasing protein relative to carbohydrates, using MyFitnessPal
(55:34) Eating as a social activity: diets that limit certain food groups are generally unsustainable, some diets work in the short term due to practical caloric restriction, weight rebound after diets, food should be fun, sustainability of diet is the most important
