Can starvation cause the body to go into fainting attacks?

Can starvation cause the body to go into fainting attacks?

Yep: The body's ability to regulate its blood pressure to the brain is greatly impaired by starvation, primarily by limitations of the amount of blood circulating around the heart (what we cardiologists call preload). In advanced starvation, the neural mechanisms regulating these matters are also impaired. Try not to ever let yourself (or your fellow man) get to that point, ok? :). ...Read more

What happens when your body goes into "starvation mode"?

What happens when your body goes into "starvation mode"?

Loss of muscle: Starvation mode is restricting calories so much (eating less all day or just 1x/day) that your body thinks the famine is coming. To protect itself and have enough energy for the day, it starts to break down muscle, not fat. Loss of muscle mass equates to more fat and a return of the weight. Weight loss is most effective when you lose only fat, not muscle. ...Read more

Does over-exercising cause the same metabolic reaction as starvation?

Does over-exercising cause the same metabolic reaction as starvation?

Yes.: Both burn fat and protein, after using what little glycogen in the body. This is not lactic acidosis, but metabolic acidosis, and occurs also in people who on low carbohysdrate diets. This a naturally occuring event. Lactic acidosis occurs when muscle, because of too strenuous activity, so Lactic Acid accumulates and causes muscle fatigue/burn. Lactic acid is reutilized and tunred into glucose. ...Read more

Been sick 6 days. couldnt eat much,maybe once a day. 500 kcal max. Now better. Did my body go into starvation mode in just 6 days?

Been sick 6 days. couldnt eat much,maybe once a day. 500 kcal max. Now better. Did my body go into starvation mode in just 6 days?

Very Unlikely: Depends on baseline muscle mass. The more muscle you have, the more packaged sugar (glucose stored as glycogen) you can hold. Your liver alone has only ~3 days worth of glycogen/glucose. In "starvation mode" the liver breaks down muscle to make glucose, and fat is converted to ketones, the 2nd best source of brain energy. If you were able to keep down 50g carb/d (can ginger ale = 366g) you're ok. ...Read more
