In W. W you are supposed to track your food,but I haven't bothered much . It is the best thing to do really. I am still getting to know the new programme. I am 61 years old so don't have those monthly fluctuations you referred to .In fact the times I put on weight have been due to mindless eating,which is usually when I eat the wrong things . It takes effort and planning to eat properly. If you have to cook for others that is a great motivator ,especially if you have children . My husband does a lot of cooking as he likes to eat a little differently to me and I am too fussy when I want to lose weight. I'm trying to get back into cooking more It's never been a love of mine,just a chore. I'm glad you are having success too.
