5 Facts Why Fat Loss Varies From Men to Women

4. Intermittent Fasting And Calorie Restriction Tends To Be Detrimental For Women But Beneficial For Men

Intermittent fasting (IF) and calorie restriction is a glaring example of how stress negatively affects women’s metabolism compared to men. Both are metabolically beneficial for most men, allowing them to lose fat, lower inflammation, and improve disease risk factors.

However, research shows fasting is harmful for female reproductive health. Anecdotally, many women have reported that fasting has caused weight gain, blood sugar imbalance, sleeplessness, missed periods, and infertility.

Where men tend to lose fat with fasting, a large portion of women gain it. The mechanism behind this discrepancy likely has to do with how the female body responds to lack of calories. Scientists believe that calorie restriction, even sporadic restriction, causes hormonal dysregulation, and excess cortisol secretion with the body holding onto its fat stores. It’s a “protective response” as the body stores the fat for future survival when calories will be scarce.

What To Do About It?

Avoid calorie restriction if you’re exercising at a high intensity or for long duration. Be very cautious with fasting. It sounds counter intuitive but if you give your body enough energy, with balanced fat, carbs and protein, your hormones will be in happy balance, stress will be lower, and your body will be more willing to give up your fat stores.
