It takes a very long time for your body to go into "starvation mode." Intermittent fasting is actually a reasonably effective dieting technique assuming you don't binge eat afterward to "make up the difference."

Other studies show metabolic rate is not impacted until 72-96 hours have passed (George Cahill has contributed a lot on this topic). > Seemingly paradoxical, metabolic rate is actually increased in short-term fasting. For some concrete numbers, studies have shown an increase of 3.6% - 10% after 36-48 hours[1,2].
