Welcome Newbies
Well I have a ways to go until I can talk about maintaining but Im sure it seems that you just got a little comfortable in the fact that you were at your goals and that you just were not keeping track like you normally would.
Like the girls said look at what your eating. And how much and when.
Are you eating a good breakfast and having your snacks and eating sensible lunches and dinners, Are you getting enough water. How much are you working our regularly. Have you incorporated any weight traing to maintain the muscle.
Im sure if when you step back and really look at what your doing you will see some improvements. Like gray eyed girl said write down what you eat that will be a big start for you to see how much of what you are eating and what you need to be eating.
You know it all comes down to eating right and exersising. Thats the jist of it. We have all head it before eat right move more. So basic yet we make it so hard. Good Luck Girls and glad to see you on the the site.
