Some major questions before I give you some advice:
1) Why do you feel the need to compare yourself to us here?
2) When you look in the mirror, how much do you like yourself?
3) Where does the view of yourself in #2 actually come from?
4) Do you really think thin/fit is ideal for you? Why?
Now as far as advice:
1) Listen to
>>1604212) Stick to lean, white meats, fish, and eggs for protein.
3) Fruits and vegetables are your friend, as
>>160423 said.
4) Learn to like filler material. Believe it or not, Ramen noodles can make a good meal as filler material. Do not use the seasoning though, as you don't need it. You can mixed this with scrambled eggs or many other meals to make a decent breakfast. Rice is also good filler.
5) Don't crash diet. EVER. They don't help you and can cause a lot of long-term damage to you.
6) EXERCISE! Diet is a major portion, but exercise is also significant. In particular, build some muscle by either doing calisthenics or weight lift. The more muscle you have, the more energy your body has to use to maintain it. Don't skimp on cardio either. Build yourself up to being able to jog for 30 minutes and maintain (look up Couch to 5K and modify it to suit your needs). If you're getting stagnate, vary it up by running up hills, using speed drills, adding some extra weight, or just jogging for longer times. Don't worry about miles. Cardio helps build extra capillaries so your muscles can receive more oxygen.
7) As
>>160421 said, make your motivation "healthy lifestyle", not "lose weight". What happens when you lost that weight? Are you going to quit? Why not since that was your motivation? Starting to see the logic?
8) Think in terms of fat loss, not weight loss.
9) As
>>160422 said, people fail sometimes. That is perfectly OKAY! Learn and try again. Sometimes you have to regress to progress.
10) Probably the most important: You got your whole life ahead of you. Learn to love yourself first before you embark on this journey. That will only make you happier as you reach your goal and love yourself more.
