Thanks for the fast reply. I will keep doing the exercises, it's still better than doing nothing. I will definitely check out Reddit too. As far as diet is concerned, getting rid of sugar is the hardest part for me, especially when my mom keeps baking one delicious cake and cookie after the other. … I'm trying to restrain myself from eating them though, with more or less success.
The pleasure of eating a cookie only exists while you are actually eating it: looking at it, smelling it, touching it, putting it in your mouth, chewing it, tasting it, swallowing it. Five minutes later, you have only a memory of eating the cookie. The memory is pretty much the same whether you ate three small bites or three big cookies.
If you only ate three small bites, you don't have the remorse from eating three big cookies. So if you are very conscious about eating treats, savoring them in small quantities and then deliberately recalling the experience, you will learn to enjoy eating treats in moderation more than in excess.
It might also help to go on YouTube and watch some especially disgusting mukbang videos to see how gross overeating is.
