Spirulina is a powdered, high-protein seaweed supplement. The dried stuff is about 60 percent protein, and, like quinoa, it’s a complete protein, meaning it can be converted directly into muscle in the body and is thus a great weight loss tool. A tablespoon of the blue-green algae delivers 8 grams of metabolism-boosting protein for just 43 calories, plus half a day’s allotment of vitamin B12, which in and of itself can give you more energy and boost your metabolism. Try tossing some spirulina into a smoothie and watching the pounds melt off. For more skinny smoothie ideas, check out this list of smoothie recipes for weight loss!

“Thirst and hunger cues feel similar, so it’s important to stay hydrated, especially if you’re trying to lose weight,” explains Moon. Yes, plain water is important, but 20 percent of our daily water intake comes from foods, she says. “Watermelon is 92 percent water, plus it is bursting with vitamins A and C and anti-inflammatory nutrients like lycopene,” she explains.
Beans are a great weight loss food that can help boost feelings of fullness and manage blood sugar levels, making them an excellent ally in your weight loss battle.

And if you need another reason to bulk up on beans, remember that the fiber and protein-rich legumes are other excellent sources of genistein—the same compound found in peanuts and lentils that aids weight loss.

While we’re on the subject of water, why not throw a few lemon slices into the hydrating and satiating beverage? In addition to adding a pop of color and flavor to a tall glass of H2O, lemon can also help encourage weight loss. Just one of the bright citrus fruits contains an entire day’s worth of vitamin C, a nutrient that has the power to reduce levels of a stress hormone called cortisol that triggers hunger and fat storage. Additionally, lemons also contain polyphenols, which researchers say may ward off fat accumulation and weight gain.
