Yo-yo weight fluctuation has little influence on the health of fruit flies

Regaining weight after weight loss is usually undesirable, but is this 'yo-yo effect' actually bad for your health? Scientists from Wageningen University recently investigated the influence of diet on the lifespan of fruit flies. In an article in today's edition of the Journal of Evolutionary Biology, they show that fruit flies do not live as long on a yo-yo diet, but this life-shortening effect does not appear to be nearly as bad as that resulting from a continuous diet with too little food. They also show that fruit flies quickly adapt to a new diet and that they are less healthy if they do not get enough food as young adult flies.
