We 'discovered' kefir right before going primal, and liked the way it made us feel too much to go without. But I'd appreciate comments on our recipe in terms of nutrition and weight loss.

1 cup kefir
1 cup frozen berries
1/2 banana
1 heaping tbsp coconut oil
1 scoop whey protein

The idea with the protein powder is to give a little weight to all the carbs. I drink my smoothie on my drive into work, then have to walk 1/2 mile from the parking lot. I notice a bit of rush feeling from the fruit I assume, and I think a little more protein helps, but it could just be my imagination.

Also, this is the only fruit I eat per day.
