There are many reasons a person would find it hard to do something about their weight. I know for me it's been a thing I have had to deal with. Even harder because I have a health issue, hypothyroidism. A lot of people who don't have health or weight issues shrug it off as if it is not a big deal and that I should be their definition of healthy. But it's not always easy.
Eating well and working out a lot I am still bigger. The lowest I have ever been was 150. But for my frame that's not too bad. But at that weight I had lost a lot of muscle, so it was not fun.
I find it hard because some people are so judgmental about it. People tell me to not worry, but it's hard to ignore it when people will come out and tell you stuff. Like "oh you must not be trying", when you are actually trying really hard. I eat way less and better than a lot of people. However I am still overweight. It's depressing when you work out at the gym, and see all these people at school who look perfect and they don't even work out or eat right. Or if they do, they don't work out much. People can say suck it up, but it is still discouraging. Even if a person is thin now a days they are still called fat by someone in society. And when you have a health condition you don't always have control of your health. In my case, my body does what it wants. I can do everything right, but at the end of the day if my condition gets worse, it gets worse. No amount of diet and exercise is going to stop it, it's something that I have, something in my body is not working as it should.
It's also hard to stay motivated to exercise and lose weight when there is this constant disapproval from other people. I used to go on walks around my city, but now I only go to the gym to do it. I had to stop going outside because people for whatever reason feel they need to harass me when I exercise. They will throw things and make comments on my weight. And FYI, I am not even that big. I am only a size 16-18, still big, but not big enough that I should cause such an uproar. Yet people treat me as if I am 600lbs.
I think for most people its just this complicated issue. Some people just assume it's easy to lose weight because they can. But not for everyone. What I have is common and there are a lot of diseases and conditions that have the same effect, and make people gain weight. It is a personal choice for some, they eat a lot and don't exercise. But I think society needs to really start to see that it's not always the case. Someone choosing to overeat is not always the main cause.
