Oh I don't want to call you lilfatti! You sound like a wise young woman to me! Many of us took our youth for granted and ate whatever we wanted without suffering consequences until we got desk jobs or it just started catching up with us. Good for you for understanding that you are making an investment in your future self! I discovered that once I started treating my body the way I should, when I reverted to my old habits, I noticed a big difference in the way I felt! You will get lots of encouragement here to make the changes you need. Welcome!
