I read all 4 pages of comments here!
I found my first natural plateau when initially joined OA and abstained from sugar and cheese for about 1.5 yrs. I dropped to 150 and stayed there.
I stopped abstaining from those foods in pregnancy, and gained a LOT, my top PG wt was 206. Midway through the PG, I took sugar out again, because I was having problems with binging on baked goods.
After my son was born, I continued to eat cheese but not sugar, and I breastfed him exclusively. My weight quickly dropped, within 3 months I had gone back to 150, and eventually hit 140. I got a stomach bug that made me feel sick whenever I ate for a few days, and dropped to 138. I NEVER thought I would weigh so little in my adult life. (As an older teen, I dropped to 128 once, but that was when I was living on the street as a run-away and eating very very little. I thought I looked AWESOME, my mom thought I was going to die of starvation...
Anyways, because I have disordered eating and body image, and the normal weight thing is not what I'm used to...I thought I needed to keep my weight below 140 to be "at goal". After all I got there once, right? When I was sick...and not eating...and breastfeeding... Hahahaha!!!! Funny, and not funny.
Along the way, I got tired of not eating sugar. I reintroduced it a few times, and my weight has gone up in response. Today, I eat healthy most of the time, eat cheese and sugar though in moderation, and am hovering between 158.5 and 161.5. I am not happy with this weight, as it's harder to fit into my clothes (bought at weight 140-150) and it's harder to buy cute clothes, which I love. I'm a thrift store shopper and love vintage clothes and cute dresses, but they are much harder to find at this weight.
I feel that if I gave up concentrated sugars and cheese again (my go-to overeating foods), I would easily drop the weight...but that was an annoying way to eat because of special occasion foods and feeling different and resentful. I'm still wrestling with that. For now, my maintenance wt chose me based on how I am eating.
