Sweet potatoes
Sweet potatoes are a source of soluble fiber, says Weiler, which aids metabolism by fueling the gut with diverse microbiota. According to the USDA, one large potato also contains 3.62 g of protein.
Greek yogurt
Thick, creamy Greek yogurt is an ideal way to start your day with a high-protein breakfast that’s great with fruit and granola. As a fermented food, it also checks Weiler’s box as a probiotic metabolism booster. “The probiotics convert fiber to byproducts called short chain fatty acids,” she explains, which are “the preferred food for our gut cells.” This helps digestion happen more efficiently and may then positively impact metabolism.
