The Claim

In adults and older individuals, isocaloric intermittent fasting results in greater short-term reductions in fat mass and interleukin-6 levels compared to calorie restriction, indicating potential early metabolic and anti-inflammatory benefits, although these effects do not necessarily lead to superior overall health outcomes.

Supports is higher

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

Cause and effect
1 study reviewed
In plain English

For older adults, going without food on certain days (but eating the same total calories) might help lose body fat and lower inflammation faster than just eating fewer calories every day — at least at first — but that doesn’t always mean better long-term health.

  1. Study: Is isocaloric intermittent fasting superior to calorie restriction? A systematic review and meta-analysis of RCTs.

    The study found that intermittent fasting helped people lose more fat and reduce inflammation in the short term compared to cutting calories, but it didn’t prove it was better overall.
