A recent study that followed a group of winners from the reality TV series "The Biggest Loser" came to some bleak conclusions:
Six years after the show ended, 13 out of 14 contestants in the study had regained a significant amount of weight. Four of them are heavier today than they were before the show began.
The results highlight a disheartening reality: Losing weight is hard work, but keeping it off is harder — especially if you're significantly overweight.
Still, the study's somber findings also draw attention to some key principles that anyone looking to losing weight and stay fit can follow:

1. Aim to lose only a few pounds each week.
Shedding pounds too rapidly can be a red flag for a diet that might encourage unsafe behaviors, and losing weight too slowly might be so discouraging you give up.
Instead, aim to lose about 1-3 pounds each week, University of Texas professor of exercise science and the executive director of the Fitness Institute of Texas Philip Stanforth recently told Business Insider.
"During the losing phase, you need a calorie deficit," said Stanforth. At the maximum, you want to burn 1,000 calories more each day than you eat. "That typically means you're losing a few pounds a week. And that tends to be a lot more sustainable than losing a whole bunch at once."
That jives well with the guidelines from the Mayo Clinic and the UK's National Health Service, both of which suggest losing one to two pounds each week.
2. Be mindful of portion size.
The standard size of many foods, whether they're fast-food, sit-down meals, or even groceries, has grown by as much as 138% since the 1970s, according to data from the American Journal of Public Health, the Journal of Nutrition, and the Journal of the American Medical Association.
So instead of cutting out a specific food group— whether its carbs or fat — you might be better off simply being more mindful about how much of everything you eat.
Of course, there are always some foods to keep an eye out for, like those with high concentrations of a few specific ingredients. A 20-ounce bottle of soda, for example, has roughly 65 grams (just about 16 teaspoons) of sugar. So go for a smaller size instead, or opt for the refreshing classic: All natural tap.
3. "Eat food. Not too much. Mostly plants."
If there's any "secret" to eating healthy, chances are it's incredibly basic. Michael Pollan said it well a few years ago: "Eat food. Not too much. Mostly plants."
Vegetables and fruits are high in key vitamins; most have a good amount of fiber to help with digestion and keep you feeling full.
Dr. Mark Hyman, director of the Cleveland Clinic's Center for Functional Medicine, says "about 70 to 80% of your diet should be plant foods," like vegetables, whole grains, beans, and fruits.
"It should basically include whole, fresh food that's unprocessed and high in fiber and phytonutrients," says Hyman, the latter of which are plant-derived compounds associated with positive health effects.
You can start small, for example, by adding a serving of steamed veggies to every dinner. This list should help you get started.
