So this is not the first time I'm dieting...I've been doing it since I was 11 where I weighed 50kg. Now I'm 14 and I weigh 63kg. Of course I know when you need to lose weight you don't have to just eat specific things for a few months and exercise but make it a lifestyle! But I just can't do it anymore and I'm tearing up right now and I've never been able to "stick to it" forever. I ate a lot since winters and now its February and just today I've started my diet where I should've been happy and motivated and all that but I'm not. I want to be slim and thin but I also want to eat all these toxic things that make you fat. I do not resist my cravings and deprive myself from food and this morning I was craving for a peanut butter and jelly sandwich that my mom, after a long time bought in the house(jelly and peanut butter) and I ate a large slice and since then I've had vegetables and fruits and green tea but I'm only hungry for that sandwich again and I want to eat at least 6-10 slices of that and I don't have any will power or resistance and my mom decided to hide it to help me and now its not in front of me but my heart knows its somewhere in the house and I'm aching to eat it again and again and I'm full on crying right now and I just can't do this anymore
Just be active, happy and don't overdo it on the "bad" foods, try and eat home cooked meals, don't snack in between, do some sport that you enjoy...if you don't feel hungry then don't eat. It's ok to skip a meal every now and then, that keeps everything in balance. It's called Intermittent Fasting (IF). All the best.
As you have noticed, diets don't work very well. You need to read some books about nutrition so you know how to eat right. Calories have nothing to do with it. You should be eating about 0.4 gram of complete protein per pound of body weight every day, counting only 6 grams per egg, 12 grams per glass of milk, and 24 grams per quarter pound of meat. Eat veggies with every meal, or whole grain bread every day, to keep your bowel movements regular.
Fat is made of carbon and hydrogen. The only way it comes out of the body is if it is turned into carbon dioxide and water and then it comes out through the lungs. So that involves a lot of heavy breathing, and that means jogging or aerobic dancing. Figure on losing one pound per week when you are doing things right.
