Muscle Loss While Dieting to Single Digit Body Fat Levels – Q&A
Question: My question is about what the maximum amount of fat that can be lost per week when someone is in single digit body fat percentage. I’ve heard it kicked around that once you start losing greater than 2 pounds or so per week that the ratio of fat to lean tissue loss starts to migrate towards the uglier side of things. However, this is presumably for people with higher body fat percentages not trainees who have been dieting for awhile to get to single digit body fat. My guess is that the hormonal and general homeostatic adaptations that occur during prolonged dieting and fat loss skew the muscle to fat loss ratio independent of any metabolic adaptation.
