Most weight-loss advice is built on the first law of thermodynamics, the law of energy conservation. Eat more than you burn and you gain weight. So the standard advice is simple: to get slimmer, eat less and exercise more.
Why eating less backfires
When we cut our food intake drastically, we feel weak, tired, cranky and low. We move less, and our appetite grows. Once the diet ends, we tend to eat more than before until the lost weight returns, sometimes with extra. That is the classic crash-diet cycle.
Why exercising more is not the whole answer
Exercise burns calories, but it also builds appetite and often leaves us tired afterwards, so we move less for the rest of the day. Many of us also feel a workout earns us an extra treat. Telling people to simply eat less and move more also wrongly suggests that weight gain is about greed or laziness. The advice is oversimplified and often misleading.
3 tips that work better
- Eat satisfying meals. Feeling deprived is the main reason diets fail. Try our 8-Hour Diet, where you still enjoy proper meals and lose weight.
- Get the right support. Our supplements are designed to help you feel full, manage your appetite and support fat metabolism.
- Drink water first. The body can confuse thirst with appetite. When you feel peckish, drink a glass of lukewarm water and wait 15 to 30 minutes before reaching for a snack.
