I make my own with frozen fruit (supermarket or Trader Joes), greek yogurt, ice and almond butter.

Most of the standard low sugar bottled protein shakes are very low calorie, like 150-200 calories, so not enough for lunch. You need something like Boost or Ensure for literal meal replacement.

Low sugar and no fake sugar taste are mutually exclusive. You'll need the calories, just get ones with sugar.

If you want something low sugar, it will have a fake sugar or stevia taste..

It either has sugar or doesn’t. There is no way around this

I have some oral health stuff coming up that might make it hard to eat for a bit. I'd like to some protein shakes on hand so I can have something simple to eat without preparation, particularly while at work.

I've only tried them a couple of times and was underwhelmed. Any recommendations for good ones - low sugar, high protein, no fake sugar taste, filling enough for lunch?
