Contrary to common assumptions, a new study from the German Institute of Human Nutrition Potsdam-Rehbruecke (DIfE) and Charité—Universitätsmedizin Berlin shows that intermittent fasting (time-restricted eating) with an unchanged calorie intake does not lead to measurable improvements in metabolic or cardiovascular parameters but does shift the body's internal clocks. Prof. Olga Ramich and her team published the results of the ChronoFast study in the journal Science Translational Medicine.
