Weight loss in obese individuals significantly reduces elevated serum Tumor Necrosis Factor-alpha (TNFα) concentrations, which may contribute to the restoration of insulin sensitivity.
For obese individuals, losing weight through a caloric deficit and exercise can lower inflammatory markers like TNFα. This biological improvement may help restore the body's sensitivity to insulin, making further weight management potentially easier over time.
GoodSupportsHIGH confidence
We conclude that obesity is associated with increased plasma TNFα concentrations, which fall with weight loss. Because circulating TNFα may mediate insulin resistance in the obese, a fall in TNFα concentrations may contribute to the restoration of insulin resistance after weight loss.
Why this rating
Randomized clinical trial with control group, clear statistical significance, but small sample size (n=38) and short duration (1-2 years).
