“Diet and exercise are a marriage that should never divorce,” said Giancoli, noting that the benefits of exercise aren’t restricted to the sheer number of calories you burn during thirty minutes on a treadmill. (Need one of those, by the way? We have some favorites.) Instead, research shows that muscle tissue burns more calories than fat tissue, proving that “muscle mass is a key factor in weight loss.”

Both Weight Watchers and Noom provide lots of guidance. If you’re more of a self-starter — someone who just needs to be pointed in the right direction — The Mayo Clinic Diet provides pure resources.

The key to sustainable weight loss is creating habits that you can (happily) live with pretty much forever, registered dietitian Georgie Fear, R.D., C.S.S.D., author of Lean Habits for Lifelong Weight Loss, tells SELF.

Close the Kitchen at Night. Establish a time when you will stop eating so you won't give in to the late-night munchies or mindless snacking while watching television. "Have a cup of tea, suck on a piece of hard candy or enjoy a small bowl of light ice cream or frozen yogurt if you want something sweet after dinner, but then brush your teeth so you will be less likely to eat or drink anything else," suggests Elaine Magee, MPH, RD, WebMD's "Recipe Doctor" and the author of Comfort Food Makeovers.
