The Claim

In obese women aged 20–45, rapid weight loss achieved through a 30–35% caloric deficit over 12 weeks does not significantly reduce plasma interleukin-1 (IL-1) or high-sensitivity C-reactive protein (hs-CRP) from baseline levels, but results in significantly higher post-intervention levels of these inflammatory markers compared to slower weight loss approaches.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

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

In plain English

In obese women between 20 and 45 years old, losing weight quickly by cutting calories by 30–35% for 12 weeks does not lower levels of two inflammatory markers (IL-1 and hs-CRP) compared to their starting levels, but leads to higher levels of these markers after the diet than slower weight loss methods.

See the scientific wording

In obese women aged 20–45, rapid weight loss (30–35% caloric deficit over 12 weeks) does not significantly reduce plasma interleukin-1 (IL-1) or high-sensitivity C-reactive protein (hs-CRP) compared to baseline, but results in significantly higher post-intervention levels of these markers than slower weight loss approaches.

    When obese women lost weight quickly by eating much less and exercising, their body inflammation didn’t go down as much as when they lost weight slowly. So slow weight loss is better for reducing inflammation.
