The simplest way to think of ephedrine is as the more potent older sibling of caffeine. Ephedrine can encourage the burning of fat mass by raising people’s metabolic rates and heat expenditure by about 5%. Ephedrine, unlike caffeine, does not require exercise to be effective, making their combination with exercise particularly synergistic. To put this effect into perspective, studies consistently demonstrated that, when on a calorie-controlled diet, placebo groups lost about an additional 5 pounds of fat in the course of a month.
Additionally, despite still being able to burn fat, ephedrine appears to have a pseudo-muscle-preserving effect that is typically not achievable in healthy humans. The very stimulatory properties of ephedrine, especially when paired with coffee, may also help with power production in the weight room or on the pavement. Ephedrine was, in all actuality, one of the most potent and successful supplements on the market, and it could benefit untrained obese people just as much as it helped trained athletes.
