How do you keep weight off after a GLP-1 program?
The National Weight Control Registry — which tracks people who have lost significant weight and kept it off for over a year — shows that maintenance is a set of measurable behaviors, not willpower. The people who succeed average 2,545 kcal/week of activity (women) and 3,293 kcal/week (men), eat 1,381-1,800 calories daily with fat under 24%, weigh themselves regularly, and correct slips within days.
The five behaviors that predict maintenance
| Behavior | Registry target | Why it works |
|---|---|---|
| Physical activity | 2,545 kcal/wk (women) · 3,293 kcal/wk (men) — ~60 min moderate daily, 7 days/wk | Upregulates UCP1, preserves muscle, keeps BMR elevated |
| Nutritional density | 1,381-1,800 kcal/day; fat ≤ 24%; whole, minimally processed foods | Minimizes passive overeating; ultra-processing disrupts appetite hormones |
| Meal consistency | 78% eat breakfast daily; 59% keep weekends identical | Weekend consistency = 1.5x more likely to maintain |
| Self-monitoring | 44% weigh daily; 31% weekly; log food ~3x/day | The scale is biofeedback — immediate correction of minor slips |
| Slip correction | Intervene immediately at 1-2 kg gain | Past that window, only 11% of dieters ever recover |
The 1-2 kg rule is the most important number
Weight maintenance isn't about never slipping — it's about catching slips inside the 1-2 kg window where correction still works. Successful maintainers treat a small gain as data and adjust immediately: a lighter week of eating, extra steps, and back to baseline. Waiting until the gain is visible in your clothes is waiting too long.
The short version
- The National Weight Control Registry shows maintainers average 2,545 kcal per week of activity for women and 3,293 for men, about 60 minutes of moderate exercise seven days a week.
- Registry maintainers eat 1,381 to 1,800 calories daily with fat under 24 percent, favoring whole, minimally processed foods to limit passive overeating.
- Seventy-eight percent eat breakfast daily and 59 percent keep weekends identical to weekdays, and that weekend consistency makes dieters 1.5 times more likely to maintain.
- Self-monitoring is near-universal among the registry: 44 percent weigh daily, 31 percent weigh weekly, and maintainers log food about three times a day.
- The 1-2 kg rule is the article's most important number, because maintainers who correct a small gain immediately recover while only 11 percent who pass that window ever do.
- Activity at these levels is credited with upregulating UCP1, preserving muscle, and keeping basal metabolic rate elevated, which is why maintenance is framed as measurable behavior rather than willpower.
