Er wordt dus ook gezegd dat een van de redenen is dat ik geen vet heb verloren is doordat ik in starvation mode zat? Of dit zo is valt nog te betwijfelen, maar vanuit gaande dat dit zo is ok. Maar in starvation mode verbrand je toch gewoon vetten? Dus moet je afvallen? Je lichaam gaat niet in een keer al het voedsel binnen houden?
Many fear that going into starvation mode will drastically reduce their metabolic rate and cause them to hoard calories and gain weight instead of losing.
This is not borne out by the infamous Minnesota Semistarvation Study (1950), 36 young, healthy, psychologically normal men while restricting their caloric intake for 6 months. Their calories were restricted in various phases, but the least amount of calories they were allowed was 50% of the "normal" maintenance calories. Notice, this was dubbed a "semi" starvation diet.
Yes, their metabolic rates were significantly lowered -- to something like 40% below baseline. Yet at no point did the men stop losing fat until they hit 5% body fat at the end of the study.
Lyle McDonald explains it this way: In general, it's true that metabolic rate tends to drop more with more excessive caloric deficits (and this is true whether the effect is from eating less or exercising more); as well, people vary in how hard or fast their bodies shut down. Women's bodies tend to shut down harder and faster.
But here's the thing: in no study I've ever seen has the drop in metabolic rate been sufficient to completely offset the caloric deficit. That is, say that cutting your calories by 50% per day leads to a reduction in the metabolic rate of 10%. Starvation mode you say. Well, yes. But you still have a 40% daily deficit.
And then he follows with the note about the Minnesota men still continuing to lose fat even thugh their metabolic rates had dropped to 40% below baseline. He says, further, that no study that he's aware of where people were put on strictly controlled diets failed to acknowledge weight or fat loss.

Wiki zegt dit: Starvation mode is a state in which the body is responding to prolonged periods of low caloric intake levels. During short periods of caloric abstinence, the human body will burn primarily free fatty acids from body fat stores.
