There is nothing worse than a skinny person telling a heavy person what to do...
So, for the record, I am probably within 10 lbs of my 5'3 ideal body weight. At one point in my recent pass, I was 10 lbs under my 5'3 ideal body weight.
It takes a LOT of hard work to staying within this goal range. And, I am not talking excercise. For the record, my excercise these days is very limited. I am talking food / eating choices.
It is the difference between a 99.9% lean turkey sandwich on whole grain bread with carrot sticks and 8oz of water opposed to a regular McDonald's hamburger and fries and small coke.
Quantity wise, they are probably the same. Chewed up, both would probably similarly weigh the same in mass or fill the same size container (picture your stomach). But CALORIE wise, omg. The sodium alone in the McDonald's meal will cause you to gain weight.
I would MUCH rather eat the McDonald's regular hamburger/fries portion from taste and comfort. And that folks, is where it is hard. It is driving past McDonalds after a long day at work and making a turkey sandwich at home.
Those are the obvious choices. But, within the turkey sandwich, there are unseen horrors. A typical sandwich portion is 3 slices of meat. But it tastes better with 6. I love Miracle Whip. But it has many more calories than yellow mustard and much more fat. My favorite bread of choice has 11 gr of fat not to mention 240 calories for 2 slices. Lettuce, tomatoe, pickles on the side. Each has a calorie rating based on a defined quantity.
When I moved to Missouri, there were no Sonics were I had previously lived. I moved down here and discovered Sonic happy hour and Grape slushes. After several months, my favorite jeans, skirts, shorts did not fit. I looked it up and that Sonic slush was 450 calories for a SMALL. Drink one of those a day for a week, on top of 3 meals that average 600 calories a day.
I don't care how tight the band on your stomach is, you will gain weight.
OP - should you decide to go the surgery route, I wish you Godspeed in healing. I have a friend who had bypass surgery and she has done an excellent job at maintaining her weight. Somewhere, deep down, she found renewed willpower to forego drizzling cheese sauce on her brocolli.
I hope you find a good support group. I do recommend that you meet with a dietician to work up healthy meal options that will give you the biggest bang of nutrition for your buck.
Once you gain the willpower over food you can spurge and enjoy that chocolate covered strawberry.
If you are a depression eater, meet with a counselor to find another outlet for your eating habits. Your life will never be without depression or sadness. (If it is, I am jealous). Find a different comfort. Once you are more mobile, horse riding, walking, bike riding, swimming all become ways to deal with stress.
Good luck to you.
