Skimp on fluids, and your body will release an antidiuretic hormone that leads to water retention that could affect the scale, Dr. Setlzer says. While this sneaky effect is one reason why the scale is a poor measure of body mass loss, you can outsmart it by drinking more—particularly if you fill your glass with water or non-calorie alternatives like unsweetened coffee and tea.
Sleep at least 7 hours a night. Eliminate all sources of light from your bedroom. Get to bed at least 8 hours before you expect to wake up, and spend the last hour before that relaxing with the lights turned down. When you sleep better, you’ll have more energy, and thus move more and burn more calories. Your body will regulate it’s appetite better. Your hormonal profile will improve, allowing you to build more muscle and burn more fat, independent of diet and exercise.
