If calories are so important for weight loss, then why does diet cola make you fat?
"If losing weight were all about the calories, then consuming diet drinks would seem like a good idea. In fact, diet drinks may be even worse than regular sugar sweetened sodas!
How does that happen?
Artificial sweeteners are hundreds to thousands of times sweeter than regular sugar activating our genetically programmed preference for sweet taste more than any other substance.
They trick your metabolism into thinking sugar is on its way. This causes your body to pump out insulin, the fat storage hormone, which lays down more belly fat.
It also confuses and slows your metabolism down, so you burn less calories every day.
It makes you hungrier and crave even more sugar and starchy carbs like bread and pasta.
In animal studies, the rats that consumed artificial sweeteners ate more, their metabolism slowed, and they put on 14 percent more body fat in just two weeks – EVEN eating less calories.
In population studies there was a 200 percent increased risk of obesity in diet soda drinkers."
