**The Effects of Alternate-Day Fasting on Weight Loss**

Researchers have found that alternate-day fasting can be an effective way to reduce body mass and fat mass, but it may also lead to a loss of muscle mass.

A recent study published in the journal Nutrients investigated the effects of a 4-week alternate-day fasting protocol on weight loss. The study involved two groups of Asian males, ages 21-35, with a BMI greater than 23. Both groups followed an alternate-day fasting regimen, where they fasted every other day and consumed only water or zero-calorie beverages while eating one small meal of 400-600 calories on non-fasting days.

The results showed that participants who adhered to the alternate-day fasting protocol experienced significant reductions in body mass and fat mass. However, this type of eating plan also resulted in a loss of muscle mass, even for those who took protein supplements.

Experts emphasize the importance of daily exercise when following an alternate-day fasting regimen, as it can help maintain muscle mass while promoting weight loss. While the study found that alternate-day fasting did not have a significant impact on blood pressure or blood glucose levels, further research is needed to fully understand its effects on overall health.
