After you lose weight, the kilos are sometimes back on in no time, with an extra kilo extra:the well-known yo-yo effect. Fruit flies also have the yo-yo effect.
Fruit flies on a diet
Wageningen UR investigated the yo-yo effect in fruit flies. They found that it slightly shortens the lifespan of a fruit fly. But the fruit flies that were continuously on a diet lived even shorter.
The lifespan of fruit flies Fruit flies that ate a lot lived an average of 61 days. Yo-yoing fruit flies lived 60 days and the diet fruit flies lived 49 days.
Lose and gain weight Fruit flies and humans have one important thing in common:they gain weight when they eat more. Furthermore, the differences between fruit flies and humans are too great to say anything about our longevity when we yo-yo, but maybe, just maybe, it's not so bad after all.
