Some of us are looking for the easiest route to our goals. And that’s not a bad thing. There’s nothing wrong with trying to maximize our efforts, and if we can reach a goal in three steps instead of in thirty then we have time to reach other goals, too.
But some things cannot be sidestepped. For all the research we’ve done into fat burners, we have consistently run across one line in all the results listed: the people that got results also worked out.
There aren’t too many cases of adverse side-effects to taking a supplement without working out. But there’s also not a lot of evidence of “miracle cures” for being overweight. There are prescription medications that are given to the obese, but even in those cases, doctors only prescribe them for weeks at a time, and with consultation to increase physical activity.
There are some ingredients in modern fat burners (caffeine, Vitamin B complexes, and guarana, for example) that will increase energy. If you take these ingredients and do not give your body an outlet for that energy you may have restless sleep, agitated mood, or hot flashes.
The main effect of taking fat burners without working out, though, is that you probably won’t lose any weight.
