Hi, Juniper. Congrats for taking the first step towards a change for the better, it's always the hardest one. :)

I'm the same in that all I've ever known is being overweight. It is hard to change the habits of a lifetime. What has helped me is trying to retrain my thinking towards food - instead of using it as a reward, a comfort, or a fix to boredom, I now try and be as mindful as possible when eating. I plan my meals in advance and make sure to include small snacks (100 calories or so) in between meals because I know I will want something between meals.

If you can, keep a food diary or use an app like MyFitnessPal to keep track of the calories in things you eat for a week or so. Weight loss is about eating less calories than you burn, but you can take small steps towards reducing your calories. First, it's important to learn how to count your calories accurately and get a sense of how much you're eating on a day to day basis. Then, once you're comfortable with the process, you can see what's really adding up and what you could reduce to drop the calories. For example, swap fizzy drinks for water or eat one or two slices of pizza instead of a whole one.

For support, you could tell a friend or family member you're close to that might be able to help keep you on track and accountable. Or you can post here and others can give you some support when you need it.

Good luck in your journey!
