Right there with you, vampy doll. That is the million dollar question! If you're doing everything the same, and the scale is showing a bigger number, a couple of things could be going on. I tend to retain a ton of water. It used to be the scale would creep up 2-3 lbs right around the time of my period, and go away when I was done. Now, I keep that water longer, and I know there is more of it. I'm takings meds for hypothyroidism (something else common at this time of life), so I know my metabolism would be slower without it. And remember your high school science - you need to eat 3500 calories over and above what your body needs to gain a pound (so if your body needs 2000 calories a day just to function, you'd have to eat 5500 calories to gain a pound in a day. Or, eat 2500/day for a week to gain a pound in a week). So, when I see my weight fluctuate, I try not to panic, and remember that I haven't eaten that many calories, and it's likely water (knowing my metabolism hasn't suddenly slowed since I'm on meds). Still exercise, still eat properly, but don't panic if you're doing what you should and the scale goes up. It will likely go down too.
One other thing to consider, you mentioned an issue with fiber (I understand that one too). Talk to your doctor about food sensitivities. If, for example, you shouldn't eat wheat, it can cause bloating and water retention if you do eat it.
Take care of you, you'll be ok.

It took me 7 years to figure out how to lose the 20 lbs I gained almost overnight when menopause hit at age 52. I am now 59 and have lost those 20 lbs-and kept them off. You can too! Email me at: getmovingwithcarole@ gmail.com for more info

I'm on thyroid and cholesterol meds since age 39 when my thyroid crashed and threw me into menopause...A probiotic helps me greatly along with a few supplements: chromium and bladderwrack that I get online. You'll need to see what works for you...it did take me years to find
the right mix for me. Good luck!

i guess no one has a real answer! i want to know too! i have gained almost 20 pounds in a year and i was not eating any more than usual although after the weight gain my appetite turned ravenous. someone told me this had to do with estrogen but i have a doctor who refuses to even discuss menopause or do something about it (yes i need to find a new doctor). i hate my body. besides the extra pounds i look different. it' not like gaining weight when you were younger. it's old lady looking body and i can't stand myself. they say menopause does not cause weight gain. i say bull ****! i have found not one thing good about menopause so far.
