I have been getting all my supplies together for the big day and I went to BJS to get protein powder. There were a bunch of choices, but only 2 for the coupon I had. One powder was for lean toning and the other was to build muscle. I knew that I was supposed to get whatever had the most protein (but at least 20 g/serving) and that was the muscle building kind (20 g vs 15 grams per serving) but the lean one had 100 calories and the muscle one had 150 calories per serving. I got the lean one and bought some vanilla almond milk to make up for the protein deficiency in case it was a big deal. But now Im curious, which is more important, protein or calories? The fact that I would be saving 150 calories a day made me feel like it was the better choice, but I guess Im not sure that I will eat enough calories for it to matter. Does anybody else use lean vs muscle protein powder? What has your experience been?

I was to,d protein at first. 69-80 g per day in liquid -food doesn't count toward that.

Sorry, 60-80 g daily.

Most important thing is to make sure it is whey protein. Some of the other proteins can cause problems. For example caseine protein forms a gel in your stomach which then releases slowly over time, obviously this is a problem if you only have a 5 oz stomach as while that is gelled in there nothing else will fit.

I was just told that it should be protein isolate.
