A trajectory of weight gain followed by weight loss results in a net gain in fat mass (FM) despite fat-free mass (FFM) returning to baseline levels.
If you have gained weight and then lost it back to your starting weight, your body composition may not be the same as it was before. You may have more fat and less muscle than you did initially. To ensure you are maintaining a healthy body composition, incorporate strength training and monitor body composition metrics, not just total body weight.
However, the gain in FM between baseline and 12 months, was not fully reversed between 12 and 24 months, resulting in a net gain in FM of 1.71 (0.4, 3.01) kg over each 24-month period.

- 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
