BTW - I am at the other end of the spectrum on weighing yourself. I do it at least every other day, sometimes more often. I like having the data and seeing the swings so that I know some days are up and some are down. It isn't always obvious which will be which either; if you only weigh once a week you can't be sure if you are seeing a spike up or down.

I don't use any artificial sweeteners or eat things that contain them. I eat things with low sugar, but real sugar. I think artificial sweeteners increase your appetite for the real thing (and there is a lot of evidence to suggest that's true).

Recommended protein is 0.8 grams per kilogram of body weight plus some extra if you are exercising. For me that means around 60 (I weigh around 162) and maybe another 15 because I walk a few miles most days.
