r11 great for you and your friend, but many people who are fat (and I mean MANY), it is NOT "yeah, I stuff my face with fatty foods and don't exercise." I think it would surprise you to find out that not all fat people stuff their faces, eat shitty food and don't exercise.
I was one of those people. I did NOT sit down with a bag of chips or cookies or cake or go to the buffet or any of those things you believe ALL fat people do. I grew up in a house where we had no junk food (this is during the 70s and 80s) because my parents were hippies and didn't believe in eating a lot of sugar. We didn't even have white sugar in our house, it wasn't allowed. Cereal for breakfast? Only if it was Wheateena or Nutri-Grain - not the stuff most or all of the kids my age ate. Soda and packaged treats? Verboten. None of that shit was allowed in our house. You know what my "sneak treat" was sometimes after school? a slice of small Orowheat wheat berry bread with a little butter. That's it.
I was always chubby, and this was a kid who rode her bike to school once or twice a week (it was 5 1/2 miles on mountain roads), had farm chores every day, rode horses, did dishes and milked a goat everyday. I was not allowed to be sedentary.
When I moved out at 18, I finally got to eat food that most of the rest of the world did, and quickly gained weight. However, I was never the kind who overindulged on a daily basis and really didn't regularly keep crappy foods in the house. There was a short period of time when I did because of who I was living with, but even then, I didn't like ice cream and wasn't really a "sweets" person.
Eventually, a lump was found on my thyroid which they couldn't rule out as cancerous and half of my thyroid was removed so it could be sectioned and examined for cancerous cells. It came back non-cancerous, so the other half of my thyroid stayed in. I started thyroid meds, but that didn't help to lose weight. I was walking miles a day, working out a treadmill, doing Weight Watchers. I even went on a backwoods camping trip for a week wherein we were on the move every day with a canoe, backpacking our own food, which was not that much food because we had to carry a week's worth of supplies with us. I came out of that camping trip having GAINED 5 lbs.
That was it for me. I went through the exhaustive process to get approved for weight loss surgery - the full-on, open RNY gastric bypass and I eventually lost 100 lbs. I kept it off for almost 21 years and then through a few years of loss, grief and heavy drinking/alcoholism gained close to half of it back. At the beginning of this year, I decided to take GLP-1 (self-pay) and lost 60 lbs. I stopped taking them about 2 months ago and haven't gained back the weight yet. I have been ravenously hungry for about the past 2 weeks but I'm addressing that with some modifications in what I'm eating and I'm going to begin hiking again now that the weather has cooled off.
I'll just add that I have another friend who gained a bunch of weight from having PCOS, not stuffing her face, and she also had the gastric bypass surgery about 3 years after I did. She also did not stuff her face or NOT exercise...in fact, she owned a Curves franchise at the time and worked out every day. She has never gained back all the weight she lost from the surgery, but she did gain about 30 extra lbs after Covid and went on GLP-1 to lose it in mid-2024 (which she did). She also hasn't gained back the weight since she stopped (about 9 months ago).
This ended up being a long post, but it is to tell you that FAT does NOT always equal gluttony and sloth. I wish more people would realize this and stop painting all fat people with broad strokes, because the need to put people in a neat little box is a RAMPANT problem for many people in this world.
