According to the Nutrition Twins, pistachios get first prize for a high-fiber weight-loss food. "When it comes to weight loss, the magical combination is to have both fiber and protein," they explain. "Many foods have one or the other, but it's rare to have both, but pistachios do! Fiber and protein work in tandem to keep you feeling satisfied, so you don't end up hungry and overeating soon after, [as] you do with many other foods that are simply high in fiber (foods like broccoli, oats, or berries) but have no protein."

One cup of pistachios (123 grams) offers 13 grams of fiber and 25 grams of protein, the ideal combo for weight loss. A one-ounce serving provides 3 grams of fiber and 6 grams of protein, and it will only set you back around 159 calories.

"Another critical thing when it comes to weight loss is stabilizing blood sugar, and fiber and protein work together to do this, preventing energy highs followed by crashes that trigger the release cortisol, the belly fat hormone," The Nutrition Twins add. "Stabilizing blood sugar also prevents sugar cravings that occur after an energy/ blood sugar crash as the body craves a quick pick-me-up. Add that pistachios are also packed with antioxidants, which is very important since inflammation makes weight loss harder."
