Tell me about this: Dr. Sims suggests a strategic calorie deficit at night can facilitate fat loss without compromising lean mass.

Dr. Stacy Sims suggests that creating a slight calorie deficit at night, away from training, can help with fat loss while preserving lean mass. This approach is effective because it ensures the body remains fueled adequately around exercise, allowing for fat loss without interfering with recovery or muscle retention. The key is to maintain proper energy levels during and around physical activity to promote body composition changes while preventing lean mass loss 1.

Dr. Sims emphasizes keeping the calorie deficit modest (around 150 to 200 calories) and ensuring adequate nutritional intake during the day, which is particularly important due to the fluctuations in appetite hormones influenced by estrogen during different phases of the menstrual cycle. This approach effectively balances energy intake to promote a healthy change in body composition 1.
