However, just like those rehab-loving design gurus on HGTV, your body breaks down muscle as regularly as it builds it. "All of the cells in your body need protein to function. When there aren't enough amino acids from food available in the bloodstream, the body will start to break down and harvest amino acids from your muscle in order to keep more vital cells—like the ones in your brain and other organs—functioning," says Dr. Paddon-Jones. "This is a natural, continuing cycle. Muscle-protein synthesis goes up after you eat a meal with protein, and your body switches back to muscle-breakdown mode a few hours after you've eaten. Normally, the ups and downs equal out and your muscle mass stays the same." However, eat too little protein for too long and your muscles start to shrink, eventually causing your metabolism to take a nosedive.

In fact, a Mediterranean diet particularly heavy in healthy fats—olive oil, eggs, nuts, fatty fish—lowers your risk of not only heart disease, but also type 2 diabetes and certain cancers, according to a new study analysis in the Annals of Internal Medicine. That’s three of the top 10 causes of death for American males that you can reduce your risk of just by eating less meat and more healthy plant-based fats. 4 Risky Exercises People OVER 40 Must AVOID
In other words? If certain foods seem to open the floodgates for you without fail, it might be better to steer clear altogether and stick with treats that don't trigger a binge. It might feel tough at first. But instead of seeing it as deprivation, reframe your decision as a choice—and a positive one at that. "Acknowledge that these foods don't work for you and the health goals that are important to you," Cederquist says.
If you really want to speed up your metabolism, start with changes to your daily activity. You'll see the greatest benefit if you can move more throughout the day. Then make diet-friendly food choices that help you to feel more energized. And lastly, skip the metabolism-boosting pills and potions (unless your doctor prescribes it). Most of them don't work and some even cause harm.
