The most surprising foods Weight Watchers considers zero points - and why

Beans and legumes are a categorically low-fat, high-protein source of fuel that give you lots of potassium, magnesium and filling fiber.

If you're not a bean lover, lentils are point-free too.

If your wallet can handle it, you can have as much caviar as you like. In fact, most fish and shellfish — like crab and lobster — are fine to eat with abandon.

According to Weight Watchers, people just don't tend to overeat seafood, so it's simply not worth measuring out into gram-specific servings. They'd rather have clients eat these types of proteins until they feel satisfied, then stop.

Many fish are high in doses of polyunsaturated fats, which can help lower your "bad" LDL cholesterol levels.

Chicken and fish have less saturated fat per serving than red meat. And both chicken and eggs have omega-3 fatty acids. These "good" fats help repair and build our cells, reduce instances of heart disease, and can also have anti-inflammatory effects. They are essential fats the body can’t produce on its own.

Although Weight Watchers encourages people to eat chicken breast, the American Heart Association says it's still best to enjoy chicken and fish in moderate doses. The AHA suggests eating no more than six ounces per day, which is about the size of two decks of cards.

There's room for some no-count sweets in the plan, too. Cherries and clementines are fine as well.

Fiber-rich fruits can be more expensive than cakey treats, but they're a much better way to satisfy a sweet tooth.

A single cup of strawberries will provide you more than an entire day's recommended dose of Vitamin C, while eating a peach is arguably as good as swallowing a multivitamin.

You could even dress them up a bit with yogurt like the figs in this image, though honey and syrup are certainly not points-free.

Yogurt is good for your bones, can aid digestion, and carries just as much protein as meat.

The cultures in yogurt can even help you lose weight, a team of Harvard researchers found.

Those ingredients include mushrooms, carrots, peppers, pea pods, onions, and tons of other leafy veggies.

The benefits of vegetable-rich meals, long a staple of the Mediterranean diets, extend beyond your waistline. Researchers have discovered that plant-based diets are good for keeping aging brains sharp, and can reduce a person's risk of developing deadly conditions like heart disease and breast cancer.

Dietitians and food scientists are increasingly pointing towards a Mediterranean, veggie and legume-rich eating plan — which is high in fiber and low in sugar and red meat — as one of the best for our health.

Whether or not you like the points model Weight Watchers uses, its guidance about eating as many fruits, veggies, and healthful proteins as we like is probably a good rule to follow.
