What is a reverse diet?

A reverse diet is the process of slowly adding calories back to your diet after an extended fat-loss phase. The goal is to rebuild your metabolic rate to maintenance without rebounding into fat gain.

How fast should I add calories?

Conservative reverse diets add 50–100 kcal per week. Aggressive reverse diets add 150–250 kcal per week. The smaller the weekly bump, the less fat regain, but the slower the metabolic recovery.

How long should I reverse diet?

Until your weight gain stabilizes at a calorie level that feels sustainable, typically 6–12 weeks. The exact length depends on how aggressive your prior cut was and how much metabolic adaptation occurred.

Will I gain fat reverse dieting?

Usually a little, a pound or three across a full reverse, and that is the cost of eating like a person again. The trade most people are making is a small, controlled gain instead of an uncontrolled one.

Is reverse dieting evidence-based?

It’s based on the well-documented phenomenon of metabolic adaptation (your TDEE drops more than predicted during a cut). The specific protocol of weekly micro-increments is more anecdotal but widely used in physique sport.

When should I stop adding calories?

When you can hit your projected maintenance and the scale holds steady for 2–3 weeks, or when you’re back to your pre-cut maintenance plus 100–200 kcal. Anything beyond that is a deliberate bulk, not a reverse.

Reverse Diet Planner

Free reverse diet planner that adds calories back week-by-week after a cut. Builds an 8-week macro schedule with protein, carb, and fat targets each week.

After a long fat-loss phase, eating at "maintenance" often isn't maintenance anymore. Months of restriction bring on metabolic adaptation: your resting rate drops, you move around less without noticing, and your real TDEE can end up meaningfully below what the formulas predict. Jumping straight back to your pre-diet calories is how a lot of hard-won progress comes back on.

A reverse diet adds the calories back in small weekly steps, commonly 50–150 kcal per week, so you climb back to maintenance instead of leaping at it. This planner builds an 8-week schedule from your current cut calories, projects each week's total, and splits it into macros on the ratio you pick. It's the same schedule MuscleBuddy builds when you move from a cut into maintenance.

How this works

The math is intentionally simple: each week, add a fixed kcal bump to last week’s target, then redistribute the new total across protein, carbs, and fat according to your selected macro split. The complexity is in choosing the right bump size and split.

Bump size: 50–100 kcal per week is conservative and forgiving: minimal fat regain, slow but durable metabolic recovery. 150–250 kcal per week is aggressive: a faster return to maintenance, but more likely to add a pound or two of fat over the reverse. The sweet spot for most lifters who finished a 12+ week cut is 75–125 kcal/week.

Macro split: the standard preset (30% protein / 40% carbs / 30% fat) is a good default: protein stays elevated to protect lean mass, fat stays high enough for hormones, and the bulk of the added calories come from carbs. High-carb and low-fat presets push more of the bump into carbohydrate, which is the macro most directly tied to training performance and the most easily oxidized for fuel.

How to use the schedule: follow each week’s targets, weigh in daily, and average the readings weekly. If your weekly average climbs by more than 0.5 lb / 0.25 kg, hold calories steady for an extra week before bumping again. If it’s flat, continue with the planned bump.

When to stop: the reverse ends when you hit a calorie level you can sustain without weight gain, typically 100–200 kcal above your pre-diet maintenance. That’s your new maintenance. From there, you either hold (a true maintenance phase) or deliberately add a small surplus to start a bulk.

Reverse dieting isn’t magic; it’s structured patience. The longer and more aggressive the prior cut, the longer the reverse needs to be. A 4-week mini-cut might only need a 2-week reverse; a 20-week contest prep often needs 8–12 weeks.
