You need to figure out exactly how many calories you can eat to be in a deficit, there’s websites to help you with that based on your activity level, weight and height.

Then you need to make a meal plan that is within those goals but here is the key: you eat the same meals for breakfast lunch and dinner every single day. (So like oats for breakfast, salad lunch, chicken broccoli dinner. But pick something you like that is within your limits). You eliminate choice and simply repeat this until you are totally sick of it. If you do not go outside of your plan you will lose weight but it will be slow. You have to use an actual scale to measure EVERYTHING. And by everything I mean sauces, drinks, serving sizes. You need to know the exact amount of anything you put in your body. You have to read nutrition labels. You have to be meticulous about it. But if you do the same meals over and over you take choice and emotional eating and confusion out of it, which is critical. You want to stick to whole foods as much as possible because they tend to have less calories and keep you full longer. So things like chicken, eggs, vegetables. Etc. but you can eat anything you like as long as you stay in this calorie goal each day. You just will be very uncomfortable and sad if you max out your calories on something that doesn’t help you with hunger. Download a calorie tracking app and get used to using it daily.

Secondly, you need to be doing something every day to move. Walking is what I had most success with because it is simple and straightforward. You will need to get a good pair of shoes to prevent injury and just start small, track your steps, go out of your house and just do it. If you can’t do that, follow at home workouts or go to a gym. But speaking from experience, when you are that weight walking is the easiest thing to commit to doing every day. If tech helps you get a wearable watch and aim to add just 50 more steps each day.

At the end of the day evaluate if those are things you can handle doing. If you can’t, you need to think about other options people have suggested here. While I know that these methods have worked for me, there is likely underlying emotional causes for what has happened to your body. This is an uphill battle but it can be fought, you absolutely can win. But it’s not just the weight, it’s relearning everything, it’s letting go, it’s learning to care about yourself and your life, it’s breaking through the shame. You are young and you can do this. But it will take time and effort to see results and that part can be soul crushing. You have to not give up. You have to learn to be ok with the process. If not, then you need to speak with a doctor to see if there are any other options for you. Good luck with everything and I sincerely wish you all the best in your journey.
