The Claim

In obese women aged 20–45, a slow weight loss intervention (15–20% caloric deficit over 15 weeks) produces a 39.59% greater reduction in plasma interleukin-1 (IL-1) and a 62.28% greater reduction in high-sensitivity C-reactive protein (hs-CRP) compared to a rapid weight loss intervention (30–35% caloric deficit over 12 weeks), indicating that the rate of weight loss influences the magnitude of systemic inflammation reduction.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In obese women between 20 and 45 years old, losing weight slowly over 15 weeks with a moderate calorie reduction leads to a larger decrease in two markers of systemic inflammation—interleukin-1 and high-sensitivity C-reactive protein—than losing weight quickly over 12 weeks with a larger calorie reduction.

  1. Study: Comparison of the Effects of Rapid, Moderate, and Slow Weight Loss Combined with a Low-Calorie Diet and Physical Activity on Inflammatory Factors in Obese Women

    This study found that when obese women lose weight slowly over 15 weeks, their body inflammation drops more than when they lose weight quickly over 12 weeks — even if they lose the same total amount of weight.
