Frequently Asked Questions

Why do men gain weight more easily after 30?

−

As men age, metabolism naturally slows down, muscle mass decreases, and hormone levels like testosterone can decline. These changes make it easier to gain fat and harder to lose weight.

Can low testosterone cause weight gain?

Yes. Lower testosterone levels can lead to increased body fat, reduced muscle mass, lower energy levels, and slower recovery after exercise.

Why am I exercising but still not losing weight?

Exercise alone may not be enough. Poor sleep, stress, hormone imbalances, unhealthy eating habits, and lack of recovery can all affect fat loss results.
