Intermittent fasting: what it actually changes
One label, several practices, one shared principle: moving when you eat. What matched-calorie comparisons actually show.
Read the articleTypes of fasting: the 20 practices explained
The word “fasting” covers practices that share neither a duration, nor a set of constraints, nor a level of risk. Compressing your meals into eight hours and going several days without drinking do not belong to the same category, however close the vocabulary makes them sound.
Each page below covers one practice: what it actually involves, what is known and unknown about its effects, its risks, and the profiles for whom it is inadvisable. One reference point holds across all of them — what determines weight is total intake against total expenditure, not the hours you choose to eat in. You can estimate that expenditure with our calorie calculator and place your weight with the BMI calculator.
