I'm a 5'11" woman and I've long thought my set point is 150 lb. I was able to test this recently- I got sick at a heavy weight, 165 lbs, and couldn't eat without wanting to throw up. I dropped 15 lbs in 3 weeks back to 150 then stopped losing weight as quickly despite the fact my issue still isn't cured- I'm 2 months into this and have only lost 5 lbs since the initial quick loss. I've also noticed that previously when I could eat normally, if I was below 150 lbs I'd really have to pay attention and work at it to stay there- I can hardly lose weight but easily gain weight up to 150, and I can hardly gain weight but easily lose weight past 150.
