I could have titled this one “Want to keep on losing weight? Stop dieting”.
The human body is wise. Back when we were hunters and gatherers, survival depended on food supply. Lack of food lead to death. So the body adapted: when food supply is low, the body’s functions slow down, which reduces the need for energy (and food). That’s how it managed to stay alive during periods of famine. Even when food was available, it never was three meals a day. Our ancestors would hunt, share their loot, feast for a day or two, and seek food again.

Today, food is abundant. Survival is not an issue. Still, this evolutionary mechanism complicates dieting and weight loss. If you diet non stop, your body functions slow down, your natural expenditure of energy lowers, and weight loss stops: your body thinks it needs to protect itself from a famine.
How do you get around that?
By alternating periods of weight loss with periods of maintenance or even slight surplus-like what would have happened naturally hundreds of thousands of years ago.
By putting your diet on hold, you give your body a break. Its functions
return to normal speed, and soon you’re ready to diet again.
Taking a break also helps on the psychological side-dieting is hard, and
after weeks of restriction, getting (partially) reacquainted with your
favorite foods is a blessing.
ACTION STEP 1
Think about the last time you’ve dieted. Did you notice a “slowing down”
of your metabolism? Symptoms include low energy levels, general
unhappiness (or even slight depression i.e. not feeling like doing
anything), and lightheadedness… Dieting for extended period of time is
also hard on your immune system: even got a cold after 6-8 weeks into a
diet? From now on, take a full week off after 3 weeks of dieting.
ACTION STEP 2
Ask people around you who’ve dieted if they experienced these symptoms.
