Keep it off! New weight loss news you need to know!

Conventional wisdom says you are born with a certain number of fat cells. It is determined by genetics and there is nothing you can do about it.

Researchers just published a fascinating study that turns conventional wisdom on its head!

First the bad news.
Scientists from the University of Colorado found that rats who were put on a calorie restricted diet to lose weight developed new fat cells when they were taken off the diet! When the weight returned in rats who were sedentary, these rats ended up weighing more than they weighed before the diet. Can anyone say 'yo-yo syndrome?'

According to Science Daily, "Small, new fat cells would not only accelerate the process of regain, but also increase fat storage capacity in the abdomen. It would also explain why sedentary rats overshoot their previous weight when they relapse."


Now the good news.
Exercise appeared to prevent the increased number of fat cells seen with weight re-gain in the sedentary rats! Not only that, but exercising rats preferentially burned fat over carbs and ate less eating than the sedentary animals.

"Taken together, the exercise led to a much lower appetite and fewer calories ending up in fat tissue."

So once again, you can lose weight by diet alone. But you can't keep it off unless you exercise.
