"For the first phase of training, I send every client to my colleague and good friend, who is a registered dietitian and MD, and they do blood work," Jason told POPSUGAR. The reasoning behind this is to find out if his clients have endocrine (hormonal) issues, which then allows him to figure out the best way to approach both training and nutrition. Once those tests have been completed, and he has a better idea of how each client's body is functioning, he'll then develop a nutrition plan.
Initially, Jason said Brie was in a calorie deficit to lower her body fat percentage. "It didn't take us too long to get her where we wanted her body composition," he explained. Once her body fat percentage was where they wanted it, he increased her daily caloric intake to fuel her workouts.
According to Jason, a lower body fat percentage helps with nutrient partitioning (where nutrients go when you eat them), "meaning the body is more efficient at dealing with carbohydrates." Jason didn't put Brie on a restrictive diet and said he encouraged her to eat a lot of carbs for energy.
