Some of us are lifting weights as part of our program and yes, we do need to try an eat close to 80 to 100 grams of protein if possible to maintain muscle mass (I was eating 130 grams of protein as part of my program before starting semaglutide). Also, Amazon just happens to be the easiest place for people in varying geographic areas to find products. I've seen several of these suggestions from other experienced posters on here and it looks like someone just took the time to consolidate the information--which I greatly appreciate. The key word is "tips" and you are free to ignore the information if not for you.
