6. Strawberry banana smoothie with kefir
Kefir is a fermented milk beverage that tastes a bit like yogurt. This drink is loaded with beneficial bacteria that are created during fermentation (3Trusted Source).
Plus, kefir packs about 12 grams of protein per 1 cup (240 mL), so it’s an excellent ingredient for a weight gain smoothie (4Trusted Source).
This simple recipe uses full-fat kefir to boost the calorie content slightly.
