There are things you can't help about your own metabolism, like aging and genetics, but they don't have the final say in how revved up it can be. If you feel like your metabolism could use a boost, check out what works (and what doesn't) below.
If you want to boost your metabolism, don't let yourself get too hungry — not only will you be more susceptible to your cravings, but also, more importantly, your metabolism will slow down to compensate for the lack of energy you're providing your body. While a little hunger can be good — it signals that your body is efficiently using up nutrient resources — forgetting to eat or otherwise taking too long between meals does the exact opposite to your metabolism than you want, so make sure to eat up!
