The wall of text:

I think you should continue to eat whatever you want like your parents say, but not however much you want. You're reducing your carb intake which is a good step! It's much better than completely cutting out carbs because your mind and body are gonna stress out over sudden diet changes.

A very difficult habit you could try to learn is to eat until you're satisfied, and not until you're full. If you'd like to start, it will help if you focus purely on eating when you're having your meals. That means no phones, no work, no TV - anything that causes you to mindlessly put food into your mouth because it makes you lose track of your fullness. You can kinda still do the above, but when you're performing the action of putting food in your mouth and chewing your food make sure to focus purely on those actions and yourself.

Also learn to be okay with not emptying your plate. It's a habit a lot of us learn as kids, but we should stop thinking about the kids in Africa because it's not our fault they're not getting food. And if you're worried about the farmers who painstakingly grew our rice, they have more machines that help them these days anyway.

With regards to snacking, obviously you should minimize it, but don't completely avoid it. Some tips are:

• Snack with a purpose. E.g. you're nearing your period and you are craving. Snacking because bored should be avoided.
• Drink a bit of plain water first. If you still want to snack after 10 mins, then go ahead.
• Put effort into your snacking. Turn snacking into an action that takes effort. Rather than reaching for a bag of chips, put some in a bowl, slice up a bit of cucumbers to have alongside it. Rather than just having some chocolate, slice up a fruit to have alongside it.
• Remember that it's still a snack and not a full meal though, so small amounts is enough.
• Focus still applies when snacking - avoid distractions while performing the action of putting food in your mouth.
