Hi,
I usually make my shakes with just water & ice.
Sometimes I add some SF syrup to my vanilla shakes and I don't notice any difference when I do or don't - regarding losing weight or not losing weight.
I like to add cinnamon to my oatmeals and chili powder and/or salsa to my soups. I don't think the seasonings add any calories. The salsa adds a little extra calories, but I read up to 2 tbsp was safe - which is more than enough for one bowl of chili or minestrone soup.
I think playing "Julia Childs"
is just fine - and a little fun too - as long as we don't go overboard - and if we're making our foods tastier, then there's a better chance that we'll keep eating them instead of getting tired or bored.
