I'm sorry but this just isn't true.
Going low calorie is one of the best ways to knock out hormonal balance which is key for any health benefits.
Even the arguments for IF are flawed in this manner as with IF you still eat the same amount of calories per day. All that is happening is the calories have a different delivery method.
Low calorie is the easiest way to cause metabolic damage.
It is very rare that anyone has any health or weight issues with the over consumption of high quality nutrient dense foods.
So i say provide the study that proves low calorie is good for ANY health benefit.
