Keto FAQ #3: What foods can I eat on keto?

A lot, actually! All animal foods are filling and healthy choices for keto – beef, pork, poultry, eggs, fish, seafood, and venison. When it comes to fruits and vegetables, go for low-carb options like leafy greens and non-sweet fruits. Nuts and seeds are also keto-friendly. Here’s a complete keto grocery list.
