What was your “reason” for gaining the weight?

Some food tastes good and I ate to much of it. No reason!

I lost my sons. They died a day apart from each other. I dealt with my grief through food and drugs. I'm currently 4, almost 5 years clean of heroin, but my weight kept going up and up as I wasn't dealing with their deaths properly.

Alcohol. Food isn't a big thing for me, I was borderline underweight until my mid-20s until I started drinking after a divorce and other problems. Still trying to conquer the war, but each day is a new battle and chance.

I was a child. My parents didn't really monitor what I was eating. I would go to food as a comfort and wasn't really aware of the amount I was eating, or what it would do to my body. I was obese for most of my childhood. I had reached 316 lbs by the time I was 15, which is what scared me into losing weight. The shock of seeing the 300s on the scale sparked an eating disorder, and for over 6 months I was eating less than 400 cals a day and burning off everything I ate through extra exercise. I still wasn't educated at that point.
Now, 3 years later, I'm more nutritionally informed, have lost over 100 lbs, and am steadily losing 1-2 lbs a week.

Both of my parents were obese and served huge portions of food while I was growing up, but when I was young I was active enough to eat a ton and stay skinny. My mother, who has some mental issues around weight, would project her fears onto me and try to stop me from eating sweets - ten tons of pasta and salad served by her was okay, but if I wanted three Oreos instead of two I couldn't have them. So I learned to buy my own food and eat it secretly. Again, I stayed skinny, being very active, but the foundation for bad eating habits was laid.

When I was in graduate school I blew out my ACL and was laid up for months. The weight started to come on then, gradually, but enough that a few years later I realized I had gained 25 lbs over my college weight, started exercising, went on a diet, and lost it. Then I got lupus and was unable to be active again, gained back plus some. Second diet, lost 50 lbs, was hit by a lupus flare and gave up. It's hard to deny yourself food when everything hurts. I became obese.

At some point I also developed Cushing's syndrome caused by an ovarian tumor, which turned out to be benign but in the meantime played games with all my hormones, as well as crushing my other organs and making me feel terrible. For more than a year I was very ill without a diagnosis, then finally the tumor caused a torsion which - after a month spent literally bedridden and begging for pain meds - finally led to emergency surgery. At some point during that month I became a diabetic - I have my bloodwork from the time of my first visit to the ER, and it was normal, and at the end of a month, I was a full-blown diabetic, probably due to the effects of stress hormones. I also lost 25 lbs during that month due to insulin resistance.

However, my diabetes turned out to be a blessing in disguise, since I finally had a caring and intelligent doctor, and no more tumor messing about with my hormones. I set out to lose enough weight to improve my insulin resistance, and succeeded. However, I will always be a diabetic, and I live in fear of a lupus flare making me unable to be active again.
