Q. I'm told my body fat percentage is 25%. What exactly does this mean, and why is it so important to track during weight loss?
Body fat percentage represents the proportion of fat relative to your total body weight. Rather than focusing on a simple number on the scale, it is crucial to understand your body composition—specifically, what your weight consists of. When muscle mass decreases, your basal metabolic rate drops, creating a vicious cycle where energy consumption decreases and fat accumulates more rapidly. Excessive fasting often leads to muscle loss first, triggering a 'survival mode' where the body conserves energy, making you more prone to weight gain even with minimal caloric intake.
