Moro et al., 2020 (1), set out to test time-restricted eating in a group of young elite cyclists. However, their study is full of errors and confusion. We do not learn much. The rare intersting result is that the young cyclists could handle 700 grams a day of carbohydrates, in the context of a total caloric intake of 4800 kCal, without an increase in insulin and triglycerides. The study by More et al., 2020 (1), is another illustration of the fact that, in certain conditions, a very high carbohydrate intake can be well-tolerated and may not damage metabolism immediately. It is, however, not clear what impact such diet may have on metabolism at a longer term.
