Summary
This study looked at whether taking a protein supplement on fasting days during a 4-week alternate-day fasting program could help young men with overweight lose fat while keeping muscle. Twenty-six men aged 21 to 35 either ate a small meal (400-600 kcal) or the same meal plus a whey protein shake on fasting days. Researchers measured body composition, blood sugar, and blood pressure before and after the program.

What this could lead to
If it works, this could point toward a way to lose weight while preserving muscle, which may help manage obesity.
What could go wrong
This is a small, early study with only 26 young men, so results may not apply to others. The fasting regimen is strict and may be hard to follow long-term.
