People regain weight because they stop doing what they were doing to lose it.
Nutrition education honestly sucks in the US, and probably isn’t great in most other countries (we’re not the only nation getting fatter, and we aren’t the fattest nation as it is). People aren’t taught how to lose weight in a healthy, sustainable way. Rather, you see shit like, “Try the new cabbage soup diet!” or “Do this smoothie diet for 30 days and lose 12 lbs!” Diets that mostly only result in lost water retention, or if you do happen to lose an actual lb or two, you’ll regain it after switching back. People generally don’t understand the concept that you need to KEEP eating less if you want to weigh less. You just teach yourself how to do so gradually. Instead, everyone wants an instant change they don’t have to keep up with.
Hollywood stars have to be in the BEST shape for many of their roles. Society as a whole doesn’t need to be super muscular (I’m not knocking it, but it also isn’t absolutely necessary). I went from 200 lbs to 120 lbs in about 2 and a half years. I didn’t have a dietician, a trainer - hell, I didn’t even go to the gym or otherwise work out. I lost my weight while having the least extra spending money, because I SAVED money not buying so much.
Gaining weight back after bariatric surgery is sadly common. Once more, this is because people return to their previous habits, rather than stick to eating within a healthy calorie allotment.
Gonna need a cite for your claim that being creative requires extra calories, much less an amount that would lead to friggin’ obesity (btw, for reference, being pregnant only requires an increase of about 400 calories a day).
Yes, the TALLER you are, the more calories you need to remain at a healthy weight. If you’re obese, however, you need to cut down on those calories. Saying, “I’m bigger, so I need more!” is a pretty dumb point to make when you’re obviously overeating. The average man needs maybe 2000-2500 calories, so a pretty tall man who is athletic or has a VERY physical job MAY need 3000 or 3200. You don’t need 4k+ calories because you shop the Big ‘n’ Tall section.
A lot of what you’re describing regarding how challenging it is to lose weight isn’t incorrect. Yes, it can be very difficult. Food addiction and binge eating disorders are a real thing. Being obese doesn’t mean you’re a lazy or unmotivated person. None of that means the solution isn’t a simple concept: You burn through weight when you stop giving your body so much unnecessary fuel. It’s insanely simple, yet very difficult to do. You have to hold yourself accountable, something so, so many people struggle with, yet still forgive yourself if you mess up. You have to work hard, without becoming obsessive. I’d 100% recommend people who are working on losing weight to see a dietician if possible, and a therapist for any mental struggles they may have. Also to seek out communities that educate and encourage others to lose weight in a healthy way. r/loseit is one really good example.
