My husband, his siblings and parents are all very thin. I've lived with his siblings during my student years in a student home, and man, they could eat, but would never gain. Their BMI all ranges from 18-21. Same for my oldest son now, he can eat and not gain anything.
Truth is: I'm surrounded by people who can eat, and need to eat much. I'm the odd one out, and have felt left out ever since I found out I have hashimoto's disease, and am currently on a medical supervised diet of 900-1000kcal per day. I gained weight very rapidly because the disease had progressed too far, and had gone undiagnosed for far too long. (It progressed while I was hospitalized for months, and I left the hospital morbidly obese) On one hand, I felt happy. The weight gain was due to a disease, not overeating, and the doctors saw what happened to my weight while I was in a hospital environment, proving what happened to me. On the other hand, It's a slap in the face to become fat because of a disease. Because people out there will still yell at you and be mean to you.
Some days, it's hard to live with it. Apart from all the nasty comments, looks and stares, I have to deal with family who doesn't understand my disease. It's hard when I get confronted with requests from my husband for very high calorie food, while I am at the extreme opposite of what he can eat. I'll be honest, I have cravings too. But there isn't room for snacks on a diet that extreme. I can only eat twice a day, and am trying not to think about food. While during his days off, he is begging me for food constantly, apart from the three times I already supply him with food during the day.
I have begged him time again not to ask me for another snack, another sandwich, another meal. MAKE IT YOURSELF or grab it yourself if you want to eat that much more. I wish he would stop confronting me with food all the time. Instead, he just keeps on snacking throughout the day. And I'll be honest. I feel petty at times, because I am jealous of their capability of remaining a healthy weight on that much food. On the other hand, as you stated, it gives me fuel to prove I can look like them while carrying this disease.
Still, I feel alone in what I do. My family knows I'm dieting (they don't know to what extent) but I feel like they try to bring me down. They constantly spout out thoughtless comments such as:
And I could add more to the list, but you get my gist. People are always trying to persuade me to eat more, or take a different approach. While the medical staff which helped me has been proud of my progress so far. (BMI 40 ->30 in 10 months). I don't know why others are wired to keep you from your goals, but I'm sure as hell sick of it.
