Yo Yo Dieting Effect on Metabolic Rate

[The Solution]

Layne Norton posted this on his facebook feed:

Interesting paper showing that weight cycling (ie yo yo dieting) may lead to lower metabolic rate than you would predict based on lean body mass. IMO this is one area of adipose research that really needs more work.

Deep body composition phenotyping during weight cycling: relevance to metabolic efficiency and metabolic risk. - PubMed - NCBI

 

[The Solution]

even slow dieting will lower metabolic rate, no question but very restrictive crash dieting will make it even worse and the adaptations will persist for a greater period of time

re is no magic anabolic window. you are slightly more insulin sensitive post workout so if you want to eat more carbs then it might be more beneficial but there's no magic here

weight cycling in and of itself is not the problem, rather how it's done... ie long restriction followed by massive overeating (binging) vs. slow controlled restricted followed by controlled refeeding
