Where exercise appears to matter most is for preventing weight gain, or for keeping off pounds once you’ve lost weight, says Slentz. “Exercise seems to work best for body weight control,” he says. The National Weight Control Registry, which since 1994 has tracked more than 10,000 people who shed an average of 66 pounds and kept it off for at least five years, would agree. Ninety percent of successful weight loss maintainers exercise for about an hour a day and their activity of choice is cardio, simply walking.
Sprints outside, on a treadmill, or even up stairs or bleachers are great to burn the most calories in the least amount of time. No equipment is really necessary and you can do these workouts just about anywhere. “Sprinting is simple, and it burns huge amounts of calories—when looking to shed weight, it tops the list,” says Adams. “While steady-state running or jogging burns plenty of calories, increasing your speed and intensity will really pay off.”
Weight Watchers is a household name for the majority of Americans. Why? Because it works. In fact, the U.S News and World Report named this the best weight-loss diet for 2016 in their annual rankings — and with good reason. The balanced program lets you eat what you want, track your choices via a points system, and build a weight loss support network with fellow Weight Watchers' members.
