This formula will help you lose weight faster, says Kristin Kirkpatrick, R.D., manager of wellness nutrition services at the Cleveland Clinic Wellness Institute. A 2016 study published in the American Journal of Clinical Nutrition suggests that increasing your protein intake while decreasing the amount of calories you consume ensures that you lose fat instead of muscle. This 35-35-30 breakdown doesn't mean you can eat any old carb or fat though, she says. Aim to get most of your healthy fat from nuts and fish, your carbs from beans and whole grains, and protein from lean sources like eggs, chicken, and fish, she says.
Sure, high-intensity cardio can help you torch calories, but ideally, you’ll also need to pump some iron to build metabolism-boosting muscle. That’s because strength training is one of the few activities you can do to spike the amount of calories you burn, even after you’re done with your workout. Case in point: one 2012 review of research found that while completing a 20-minute resistance training circuit may help you burn 200 calories, your body’s resting metabolic rate stays elevated for the next hour, helping you burn an additional 50 calories. Plus, when you lose weight, you lose some muscle with it, so building and maintaining that lean mass will help you achieve a more toned look.
6. Selenium: This mineral is crucial to regulating your thyroid, the gland in your neck that regulates your metabolism. What’s more, the thyroid is responsible for producing hormones crucial to an efficient and balanced metabolism. Since selenium is commonly found in seafood like tuna and oysters, most land-locked folks could benefit from a supplement of the stuff.
In the study described above, the participants had to shut down the kitchen after 7 p.m. What’s so magical about this time? By 7 p.m., the researchers found that most participants had likely already consumed dinner (so there was no need for the study participants to skip meals and totally deprive themselves and their metabolism). You’ll likely agree that once dinner is over, your late-night snack options aren’t always healthy choices. By shutting down the kitchen (at 5 p.m. or 6 p.m. or 7 p.m. or even 8 p.m.), you’ll be more likely to eliminate consumption of late-night empty calories.
At its core, burning fat comes down to the process of lipolysis—the breaking down of fat lipids, explains Seedman. This happens in the mitochondria of the muscles, or the powerhouses of the cells, responsible for generating the energy our cells need to do their jobs. Exercise has been shown to improve mitochondria function, which then promotes fat breakdown, Seedman adds. Plus, working out helps regulate pretty much all the hormones that optimize fat loss.
