Grant yourself a cheat day from time to time but stay on your diet the first months. I’ve been on a diet for about three years now and I can have a cheat day once a week.
Expect it to be something you have to commit to the rest of your life but believe me, it gets easier. Don’t go on a crash diet but do something that you realistically can maintain.
Then start with some moderate exercise. Just walking more often is a great way to lose weight.
You can’t target zones to lose weight but you can tone zones by building muscle. Bigger shoulders lake your waist look thinner.
Stick to it. You’ll feel better overall. Good luck.
