There are two golden rules that you should keep in mind when trying to shed those extra pounds off your body:
1) There are 3500 calories in one pound of fat; and
2) That you should reprogram your metabolism to go into burn-fat mode.
In other words, to lose one pound you should burn 3500 calories and those calories should come from your stored fat.
However, your body will start burning fat only when it doesn't have other more readily available energy sources to resort to. Needless to say it, the first choice source of energy is sugar.
Sugar runs in our bloodstream and it’s also stored in our muscles and liver as glycogen.
When your body runs out of sugar that's when it starts burning the reserves (i.e., stored fat), and, as a consequence, you’ll lose weight.
The end of the story is that to get thinner you have simply to drastically cut your overall sugars intake.
