Hello everyone, I was wondering if metabolic damage real. It is a topic heavily discussed in the high-carb vegan community. Metabolic damage is the damage caused by long term calorie restriction, either through dieting or eating disorders. People who have a history of calorie restriction gain back the weight they've lost and sometimes even more. It is hard for them to get to a healthy weight. They even gain weight while eating a plant-based diet. The first time I heard about this was from a YouTuber named freelee the banana girl. She had recovered from an eating disorder and discovered veganism. At first she gained a lot of weight, but she gradually began to lose after her "metabolism recovered".  Is there any research proven that metabolism can be damaged and then repaired by eating high nutrient foods?

Hi Christina, 

Thanks for posting your question.

Restriction of caloric intake (up to a certain point of restriction) has been shown by credible scientific studies to prolong life and reduce disease, IF the person follows an oil-free low-fat plant-based diet of whole unprocessed foods.

Now I will paste from the FB page of Jeff Novick, MS, RD who has generously laid out the URLs for us of these studies:  

Sincerely,

Dr. Carney

From Jeff Novick, MS, RD:

Here are the Shintani studies..

And here is the another abstract you might find helpful:

Abstract 

Purpose of the review: The present review discusses the current state of knowledge regarding the effects of calorie restriction in modulating metabolism and aging. 

Recent findings: There are currently no interventions or gene manipulations that can prevent, stop or reverse the aging process. However, there are a number of interventions that can slow down aging and prolong maximal lifespan up to 60% in experimental animals. Long-term calorie restriction without malnutrition and reduced function mutations in the insulin/IGF-1 signaling pathway are the most robust interventions known to increase maximal lifespan and healthspan in rodents. Although it is currently not known if long-term calorie restriction with adequate nutrition extends maximal lifespan in humans, we do know that long-term calorie restriction without malnutrition results in some of the same metabolic and hormonal adaptations related to longevity in calorie restriction rodents. Moreover, calorie restriction with adequate nutrition protects against obesity, type 2 diabetes, hypertension and atherosclerosis, which are leading causes of morbidity, disability and mortality. 

Summary: More studies are needed to elucidate the molecular mechanisms underlying the beneficial effects of calorie restriction in humans and to characterize new markers of aging/longevity that can assist clinicians in predicting mortality and morbidity of the general population.
