Incredibly stupid study. 800 calories a day is not a diet, it is starvation. Of course metabolic rate is going to slow way down.

  I think it has more to do with how fast you lose it than how few calories you eat. The Biggest Loser contestants ate 1200-1500 calorie diets and still had abnormally low BMR even 5-10 years out.

    You've mentioned the biggest loser study a few times, but my understanding is the metabolic adaptation of BMR is thought to be due to their dramatic increase in physical activity, not just the caloric restriction https://onlinelibrary.wiley.com/doi/epdf/10.1002/oby.23308 https://onlinelibrary.wiley.com/doi/epdf/10.1002/oby.23308

      Yes, that is what I was referring to. Although I think it was though to have more to do with the dramatic weight loss rather than the increase in physical activity or caloric restriction. 1200-1500 calories is a very reasonable daily restriction.
