i am only an expert on my personal experience. I have lost weight twice in my life, dropping from 265 to 215lbs. Once on a very strict Atkins variant (50 grams of carbs per day) which also normalized my blood glucose. The other time by riding my bike 130 miles per week and running 15 miles per week. It took me a year to build up to that. 48 resting heart rate, 115/60 blood pressure. At 40 years old I could run six 7 minute miles or one 6’30” mile. I do not have a runners body type. My legs are short and my torso long.
In both cases, I stalled at 215lbs (5’10”) and did not lose more unless I kept myself VERY hungry. I never got below 210lbs.
I think there is more to it than eat less move more.
How long was your stall for before you decided to change your eating habits? I just put up with a month long stall, I hit 193 coming out of June and spent the entire month of July bouncing between there and 195. Really made me mad too because 185 is my final goal and when I hit 193 I was really excited about hitting the last length. Finally things started trucking again the first full week in August, bouncing around 190 now and I didn’t change anything. Plateaus can last a long time, and the closer you are to your natural body weight the harder the whole process is, which means the plateaus get longer.
And of course there is more to it, which I haven’t denied. You have a body type which might include various hormonal conditions, this will all determine what your natural body weight is. But it’s very rare for someone’s natural body weight to be what a normal person (and yes I am deliberately discounting the BMI) would call obese, these people exist of course but they’re a statistical anomaly. And of course even for these people making sure their diet is healthy and getting some exercise isn’t going to hurt them, even the genetically obese can be obese in a healthy way, obviously they’re never going to be Jack Lalane healthy but they can get themselves to the point where they can do normal household activities and not gasp for wind.
