Time-restricted eating focuses on the eating window rather than overall calorie reduction.

“difference between fasting & time-restricted eating”

“Study concluded time-restricted eating is no more beneficial than calorie restriction. Calorie intake was similar but time-restricted eating group only stopped eating 2-3 hrs max before the calorie-restricted group.”

“The reason why we coined and use the word time-restricted feeding is we are not restricting calories, at least in experimental animals. So in that way the intermittent fasting came from calorie restriction, and every other day feeding that had a serious component of caloric restriction that many people thought is difficult to achieve. So that's why we stayed away from the word caloric restriction or fasting, and we used the word feeding because people thought, people may have a positive attitude towards it.”

“So in this way it becomes very easier because you just have to...we all know how to manage our time, on a daily basis we are always dealing with time. So it becomes easier because if we start eating around, say, 8:00 in the morning and, based on our lifestyle, we can do 10 hours eating, then I'll have my dinner, say, around 6:00. So that's the concept of time-restricted eating or time-restricted feeding.”

“Whereas the term time-restricted eating generally refers to eating within X number of hours, where the X can be somewhere between 8 to 12 hours in experimental models, preclinical models, and without explicitly reducing calorie. And that's a big caveat between caloric restriction, scientific term intermittent fasting and time-restricted eating.”
