Working mainly with carbohydrates

The supply of stored carbohydrates (https://fitcrasher.com) only lasts a couple of hours (or less) after doing some kind of intense activity or exercise. But your fat reserves contain enough energy to keep you going for weeks or even months.

When you are used to working mainly with carbohydrates (as most people do today) your fat reserves are not available easily, so they can not fuel your brain.

This makes us have to supply our body constantly before https://fitcrasher.com, during and after long sessions of exercise. Or even just to provide the necessary energy for our daily activities and avoid hunger and bad mood.
