They say that pumpkin is a lower carb replacement for banana in a smoothie.Not exactly keto if you use bananas. Fruit is not keto usually due to your body processing it as sugar. The yogurt would depend on the ingredients and the carbs. There are some new ones out that are low carbs. It has to do with the way the milk is processed. The carbs are in the whey.
I don't make smoothies. I use Keto Chow, which is a healthy replacement meal. It gives you one third of the vitamins and minerals you need for the day. Not meant to replace all three meals of your day. Just one. Or when you are in a hurry and can't fix a meal. I could drink it as a shake or use it in a recipe (they have lots of recipes on their site). But I like it as ice cream for my midday meal. Taste good and good for me.
