Um Yah Rach if you have a pooch, well it must be tiny.
Yes we all reach an age when the hormones stop, and our waist line tends to go away, and we get a bit thicker. The only way to get totally rid of it permanently is a tummy tuck, and then never gaining another ounce of weight.
I think you are actually a bit too thin, based on the pic you posted, and should not worry. After all that little pooch if proof that you made wonderful, beautiful, people. You should be proud of it.
