In patients with inflammatory bowel disease (IBD) and obesity, weight loss therapy should prioritize selective fat mass reduction while preserving lean body mass (muscle) to avoid worsening sarcopenia and surgical risk.
If you have IBD and are overweight, your weight loss goal is different from the general population. You must prioritize keeping your muscle mass. Standard diets that just cut calories might hurt your muscles. You need a plan that specifically protects lean body mass, likely involving higher protein intake and monitoring muscle function, not just the scale number.
More precisely, intervention should lead to a selective reduction of fat mass without reducing muscle mass or lean body mass. This ideal cannot be achieved at 100%, neither by non‐surgical nor by surgical means. Therefore, we still use the term body weight reduction instead of body fat reduction, although the work group fully agrees that any obesity therapy needs to aim at preventing of loss of muscle mass as much as possible.
Why this rating
Based on observational studies and expert consensus (GPP) rather than RCTs of weight loss interventions in IBD.

- Obesity in IBD patients is associated with altered pharmacokinetics of biological therapies, leading to faster drug clearance, lower trough concentrations, and potentially reduced treatment efficacy.Limited
- Sarcopenic obesity (high fat mass combined with low muscle mass and function) is a distinct and high-risk phenotype in chronic liver disease (CLD) and IBD, associated with worse prognosis, higher mortality, and increased surgical complications compared to obesity alone or sarcopenia alone.Limited

- 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
