Great, the guy asked for a serious reply
and he gets a sales pitch from some road
travelling medicine man
it does not matter if you eat after six or
not. The problem is after
dinner/supper/eveing meal, you have
reached your calorie budget for the day.
So, if you eat after that, you are going
over your calorie budget and may gain
weight.
The idea that what you eat after 6pm or
8pm turns to fat is bs. The time of day
you eat is not the problem. If your body
needs the calories or not, is the main
thing.
