How does mushrooms fit your goals?

With 2.2g of protein per 1 cup sliced (70g), mushrooms is a workhorse for anyone tracking macros for weight loss or muscle gain. Protein is the most satiating macro and the hardest to over-eat by accident, which is why high-protein foods anchor most successful cutting and recomposition plans. A single serving covers roughly 1% of a 150g daily protein target — the kind of number that adds up quickly when you build meals around it.

Diet-wise, mushrooms fits keto, low-carb, high-protein, and vegan and vegetarian eating patterns.
