A weight loss plateau is frustrating, but it usually has a simple cause: your calorie deficit shrank. As you lose weight, you burn fewer calories. If you keep eating the same, fat loss slows or stops.
Plateaus are data, not failure.
First: Make Sure It's a Real Plateau
Water weight can hide fat loss for 1-2 weeks. Before you change anything, check:
- Has your weekly average weight been flat for 14+ days?
- Are measurements and photos also unchanged?
- Did stress, sleep, sodium, or a hard workout increase water retention?
The 6 Most Common Causes
| Cause | Fix |
|---|---|
| Portion creep | Weigh foods for 7 days and reset accuracy |
| Less movement (NEAT) | Add steps (start +2,000/day) |
| Metabolic adaptation | Small calorie drop or a diet break |
| Poor sleep/stress | Fix sleep schedule, reduce deficit intensity |
| Weekend blowouts | Track weekly calories, not just weekdays |
| Over-aggressive deficit | Increase protein, lift, take diet breaks |
How to Break a Plateau (Step-by-Step)
- Track accurately for 7 days. No guessing.
- Add steps. It is the least stressful lever.
- Adjust calories slightly. Drop 100-200 calories/day if needed.
- Keep lifting. Protect muscle and keep metabolism higher.
When a Diet Break Helps
If you have been dieting hard for 8-12 weeks, a 1-2 week diet break at maintenance can reduce fatigue and improve adherence. It is not a cheat week. It is planned.
Frequently Asked Questions
How long does a weight loss plateau last?
If you do nothing, it can last indefinitely. With accurate tracking and a small adjustment, most plateaus break in 2-4 weeks.
Should I cut more calories?
Only after you fix tracking and steps. Most plateaus are accuracy and movement issues, not a need for a massive cut.
