Long-term weight loss maintenance using a low-carbohydrate diet is possible and results in no greater weight regain compared to other dietary approaches over a 3-year period.
If you have successfully lost weight using a low-carbohydrate approach, you can likely maintain that loss long-term without needing to drastically increase your physical activity or dietary restraint compared to others. The key is adherence to your chosen dietary pattern, regardless of whether it involves higher fat intake or lower exercise volumes, as long as you maintain your weight loss.
It is possible to achieve and maintain long-term weight loss using a low-carbohydrate diet... No differences in 3-year weight regain were observed between low-carbohydrate dieters and other Registry members in intent-to-treat analyses (7.0 (+/-) 7.1 vs. 5.7 (+/-) 8.7 kg).
Why this rating
Observational cohort study (National Weight Control Registry) with self-reported data and significant attrition, though intent-to-treat analysis mitigates some bias.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
