Remember I wondered if intermittent fasting could exacerbate sarcopenia (muscle loss)? Here’s some evidence that it could:
Background:To preserve muscle mass and therefore limit the risk of disability in older adults protein intake is seen as important factor. Besides the amount of protein, its distribution over the day is thought to affect protein anabolism.
Conclusions: In this sample of healthy older persons, amount of protein intake was not associated with frailty, but distribution of protein intake was significantly different between frail, pre-frail and non-frail participants.
Everyone ate about the same amount of protein in a day. But while healthy non-frail participants distributed their protein throughout the day (a little at each meal), frail participants consumed the bulk of their protein during one meal, the midday meal.
There was no significant difference in the amount of protein ingested between frailty groups and we found no reduced risk for frailty in the quartiles with a higher protein intake compared to the lowest quartile.
Eating enough protein is important, but eating a lot of protein doesn’t necessarily prevent muscle loss. See: Eating More Protein Is Not the Answer To Preventing Sarcopenia (Age-Related Muscle Loss)
Eat regular meals. Don’t skip (or skimp on) meals. And try to get some plant-based, protein-rich foods in all your meals. (Remember, animal-based protein promotes sarcopenia.)
