Unchecked obesity trends in the US population are projected to cause a decline or leveling off of life expectancy in the first half of the 21st century, reversing historical gains.
The steady rise in life expectancy is ending due to obesity. To maintain or extend your lifespan, you must address obesity now, as medical treatments for resulting diseases like diabetes and heart disease are insufficient to counteract the mortality risk. Focus on preventing obesity, especially in children, as the primary lever for longevity.
We anticipate that as a result of the substantial rise in the prevalence of obesity and its life-shortening complications such as diabetes, life expectancy at birth and at older ages could level off or even decline within the first half of this century.
Why this rating
Based on large cohort studies and demographic modeling, though it is a projection rather than a completed clinical trial.

- 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
