You've finished your cut. The diet worked - you're leaner than before. Now what? If you immediately go back to eating normally, there's a good chance you'll regain most of the fat you lost within weeks. This is where reverse dieting comes in.
Reverse dieting is exactly what it sounds like: dieting in reverse. Instead of decreasing calories to lose weight, you gradually increase them to find your new maintenance level without triggering rapid fat regain.
Why You Can't Just "Go Back to Normal"
After an extended calorie deficit, your body has adapted in several ways:
- Your metabolism has slowed - NEAT (non-exercise activity thermogenesis) decreases. You move less without realising it.
- Hormones have shifted - Leptin (satiety hormone) is lower. Ghrelin (hunger hormone) is higher. You're biologically primed to overeat.
- Your "maintenance" has dropped - What used to be maintenance calories might now be a surplus.
- Psychological restriction effects - Weeks of saying no to foods makes them more appealing. The urge to binge is real.
This is why most people regain weight after diets - they return to previous eating patterns without accounting for metabolic adaptation.
How Reverse Dieting Works
The concept is straightforward: increase calories slowly enough that your metabolism can upregulate without storing the excess as fat.
Example Reverse Diet Protocol
Typical protocols add 50-150 calories per week, primarily from carbohydrates (which help restore leptin levels and support training). The process usually takes 4-12 weeks depending on how aggressive your cut was.
The Phases of Recovery
Initial Recovery
Add 100-150 kcal weekly. Expect some water weight gain. Energy and mood start improving.
Metabolic Upregulation
Hormones normalising. Training performance improving. Continue gradual increases.
New Maintenance
Find the calorie level where weight is stable. This is your new baseline.
What to Expect
You Will Gain Some Weight
This isn't fat - at least not mostly. When you increase carbohydrates, your muscles store more glycogen. Each gram of glycogen holds 3-4 grams of water. A 2-4lb (1-2kg) increase in the first week or two is normal and expected.
This is actually desirable. Those glycogen stores fuel your training. You'll look "fuller" rather than "flatter" - muscles more defined, not less.
Don't Panic at the Scale
If you immediately cut calories because the scale jumped 2kg, you'll undo the whole process. Trust the plan. Water weight is not fat. Give it at least 2-3 weeks before making adjustments. Track measurements and photos, not just weight.
You Will Feel Better
Positive Changes During Reverse
- Energy levels increase noticeably
- Training performance improves - more strength, better recovery
- Sleep quality improves
- Mood stabilises (no more diet brain fog)
- Libido often returns to normal
- Better body temperature regulation
Where to Add the Calories
Most coaches recommend prioritising carbohydrates during a reverse diet:
- Carbs first - They have the strongest effect on leptin and support training. Add rice, oats, fruit, potatoes.
- Fats secondary - Small increases help with hormone function and satiety. Nuts, olive oil, avocado.
- Protein stays constant - You were hopefully eating enough during your cut. No need to increase significantly (1.6-2.2g/kg is still the target).
Common Mistakes
1. Going Too Fast
Adding 500 calories overnight might feel liberating, but it outpaces your metabolism's ability to adapt. Result: fat regain that could have been avoided.
2. Stopping Too Early
Some people reverse to a point that's still below their true maintenance, then wonder why they still feel tired and hungry. Keep going until you reach a genuinely sustainable intake.
3. Cutting Again Too Soon
If you reverse for 4 weeks then start another cut, you never gave your metabolism time to recover. Spend at least as long at maintenance as you spent dieting before cutting again.
Is Reverse Dieting Necessary?
Honestly? The evidence is limited. There are no large studies specifically on reverse dieting protocols. What we know comes from metabolic adaptation research and practical experience from the bodybuilding/fitness community.
Some people can transition to maintenance more quickly without problems. Others need the gradual approach. If you've done aggressive, long-term calorie restriction, a structured reverse is probably wise. For moderate, shorter cuts, a faster transition might work fine.
Key Takeaway
Reverse dieting is the often-overlooked exit strategy from a calorie deficit. By gradually increasing calories over 4-12 weeks, you give your metabolism time to upregulate while minimising fat regain. Most importantly, it teaches you what genuine maintenance eating looks like for your body - the real key to keeping results long-term.
