The Claim
Diet-induced weight loss in adults with overweight or obesity is associated with a non-significant 1.7 kg reduction in handgrip strength overall, but with a significant 4.6% decrease in handgrip strength among those following moderate energy restriction, indicating that the magnitude of handgrip strength change depends on the degree of caloric restriction.
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 adults with overweight or obesity, losing weight through dieting is linked to a small overall drop in handgrip strength, but a larger drop in those who reduce calories moderately.
See the scientific wording
Diet-induced weight loss in adults with overweight or obesity is associated with a non-significant 1.7 kg reduction in handgrip strength overall, but a significant 4.6% decrease in those following moderate energy restriction, indicating that the effect on upper limb strength depends on the degree of caloric restriction.
When a person eats significantly fewer calories, the body breaks down muscle tissue for energy, especially in the arms, which makes the hands weaker.
What the research says
1 studyWhen people with extra weight lose weight by eating less but not extremely low calories, their hand strength tends to go down a little. But if they eat very, very little, their hand strength doesn’t change much. The study found this exact pattern.
