I’d think carefully about the injections as although they may help with the initial weight loss, they can come with side effects (sometimes serious) and it doesn’t address the issues when you eventually come off the jabs. There is a definite chance of relapse long-term, which hasn’t yet been publicised much as jabs are still relatively new. Whilst you obviously want the weight off to help your health, who knows what the longer health implications will be from taking medicine.
Instead of looking to drastically change everything to drop weight quickly, could you look at your calorie allowance and just knock a few hundred off to lose weight slowly? That is far more sustainable, doesn’t involve labelling any foods as bad per-se and hopefully avoids binging.
Eating more veg and low-cal foods will give you the volume of food to fill you and leave less space for the empty calories. Can you focus on finding nutritious meals that are packed with flavour so you don’t feel you’re missing out. There’s no sense in eating 1000 calories of veg if that won’t make you feel satisfied and result in you still eating 1500 calories of rubbish to get that hit.
Could you look at when you’re most likely to want to snack or comfort eat and plan that into your routine, so you leave enough calories for something then but add in something healthier too, to bulk it out. For example, if you like crisps, have less plain nachos and eat with homemade veggie chilli (beans to fill you and for nutrition). Or chocolate but less and crumbled over Greek yogurt and berries, so again it fills you more and packs in the vitamins?
Also, look at fats that you consume with those carbs. Carbs have been demonised but in reality, who eats plain rice or boiled potatoes without butter, jacket potatoes without butter and cheese, mash without butter/milk/cream. If you could cut the fat down, I don’t see anything wrong with moderate amounts of carbs. I whack fage yogurt in my mash (as an example) and plenty of seasoning, or cook a veggie curry (using yogurt instead of cream) and have that on a jacket potato as I don’t need the butter then for moisture. I avoid toast as I can’t have that without lots of butter, but you could spread runny eggs over toast or beans. It takes time for our palettes to adjust but I just think carbs in their natural state are not an issue as no one eats them without being paired with fats and sugar. It’s the combo which is calorific and doesn’t fill you. You could eat 500 calories of plain potatoes and be very full - far less full with 500 cals of chips though or potatoes laced with butter.
Sorry it’s a long post but hope some of this is helpful. Diet is such a tricky thing and there’s conflicting info everywhere but I really believe that trying to have moderation and some of what you enjoy (but tweaked) is the best way for long-term success. Pinch of nom cookbooks are pretty good for fakeaways.
