Will drinking too much of beer increase the size of belly? Someone told me that drinking beer will increase the size of our belly. Is it true? Since I don’t drink beer, I don’t have any idea about that.
Most beer has a lot of calories. Just like any other calorie intake, if you consume more than you burn, you will gain weight.

So, yes, drinking "too much" beer will "increase the size of belly". What "too much" means, however, is dependent on your other habits.

The typical "(beer | pot) (belly | gut)" is usually "Abdominal Obesity" which, by definition, means obesity in the abdominal area specifically, i.e. the belly.
