With BLUE you'll know your target number of calories. You'll be able to achieve sustainable weight lose, achieve your goal and maintaining your ideal weight.
To successfully lose weight you need to reduce the number of calories you eat between your RMR and your TEE.
If your calorie intake is less than your RMR, your body goes into famine mode.
Programmed thousands of years ago, the body shuts down at the first sign of famine.
So instead of burning fat, the body slows right down and tries to conserve fat. In famine mode the body will burn muscle instead.
The story gets worse.
When you come off your diet and your calorie intake rises above your RMR, your body's survival instinct lays down more fat. It fears the next famine will be just around the corner.
This is why most people end up heavier than they started after dieting.
