Hey Monique, and
Congratulations on your wedding! Turning 40 isn't going to make your metabolism go FASTER, but we have TONS of people in that age range who've lost weight - nothing is gonna stop you but you! Have you visited our "40-somethings" area yet? Check it out!
If I may give some advice, try not to focus too much on hitting that 2 lb per week, every week goal. Sometimes, you can do EVERYTHING right, and the scale still won't cooperate. So focus on staying on plan, doing the best you possibly can, and the scale will go with you eventually.
Can't wait to hear more from you soon!
