What is a diet break?
Updated 2026-08-16By Chris RichardsAll terms
Definition
A diet break is a planned period of eating at maintenance in the middle of a fat-loss phase. Reverse dieting is the slower climb from a deficit back to maintenance after the phase ends. Both are tools for adherence and measurement — not metabolic magic.

Definition
A break is not a binge week. It is eating at measured maintenance calories for one to three weeks while you keep logging and weighing. Hunger usually eases. NEAT often recovers a little. The weekly average should go roughly flat.
Reverse dieting is the exit: add 50–150 calories at a time, hold a week or two, and stop adding when the trend is flat. Jumping straight from a deep cut to “whatever” is how a lot of the lost weight returns in a month.
When a break is the right tool
When training quality has fallen, when you cannot remember the last social meal that fit the target, or when you need a clean maintenance measurement after a large weight change. It is also reasonable simply because you are tired of the cut. That is a legitimate reason.
The mistake people make
Calling a weekend of untracked eating a diet break. Without a target and a log, you cannot tell maintenance from a surplus. The other error is fearing that two weeks at maintenance will “undo everything”. Two weeks at true maintenance hold weight. That is the point.
FAQ
How long should a diet break last?
Long enough for the weekly weight average to flatten and for you to feel like logging is ordinary again — often one to three weeks. There is no official protocol.
Is reverse dieting required after a cut?
No, but an abrupt jump to unrestricted eating is how people regain. A slower return to maintenance is just a controlled surplus-avoidance plan.
