The Study
The relationship between watermelon consumption and sarcopenia in an elderly general population: findings from the Tianjin chronic low-grade systemic inflammation and health study
This study found that people who ate more watermelon tended to have stronger muscles, but it didn't watch them over time to see if eating watermelon made their muscles better. Maybe people with strong muscles just like eating watermelon more — we don't know which came first.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — a 51% lower chance is a big difference, similar to the benefit of regular exercise or eating more protein.
- 2People who ate watermelon 2–3 times a week had 51% lower chance of muscle loss; those who ate it once a week had 28% lower chance.

Elderly Chinese adults aged 60 and older who eat watermelon at least two to three times per week have a 51% lower odds of sarcopenia compared to those who eat it less frequently, after accounting for other lifestyle and dietary factors.
People who eat watermelon have lower rates of muscle loss with aging, and this link is stronger in people who do not have high blood lipids than in those who do.
Elderly Chinese adults who eat watermelon have a lower risk of sarcopenia compared to those who do not, regardless of how much tomato or other lycopene-rich foods they consume.
Elderly Chinese adults who eat watermelon at least two to three times a week have a 51% lower odds of sarcopenia than those who do not eat it, and those who eat it once a week or less have a 28% lower odds.
Men who eat watermelon two to three times a week have a lower risk of sarcopenia compared to women who eat the same amount, where no reduction in risk is observed.
Eating foods high in citrulline regularly leads to more stable physiological effects than taking a single dose of citrulline.
