One last point: Because steroids have all these side effects, a lot of abusers will then take other drugs to offset the effect—steroid abuse causes you to grow man-boobs, so people take another drug to mitigate those side effects. Guys who take steroids often also take augmenting drugs to decrease estrogen production or to improve athletic performance even further, like human growth hormone, insulin-like growth factor 1, insulin, erythropoietin, stimulants, diuretics, levothyroxine, and/or gamma-hydroxybutyrate, according to the study in FP Essentials . That means on top of all these side effects of steroids, most abusers are also looking at a whole separate list of effects from their peripheral drug habits.
There are, however, some foods where the caloric expenditure to process them is a little higher than the calories they provide the system. The clear example is water, especially ice-cold water. The body needs to warm it up before absorbing it, leading to a small caloric debt. Foods with very high water content, such as celery, also have this tiny catabolic effect. But the nutritional value of water and celery are not high enough to properly sustain an organism, so relying solely on these foods to lose weight can lead to serious health complications.
