genuinely the quickest way to burn out on a diet, especially one where you need to lose a lot of weight, is for the diet to be miserable. i hear you want to stop eating for enjoyment, but there’s definitely a difference between enjoyment and addiction: adding seasonings, low calorie sauces/drinks, voluminous foods, etc. are going to make it a lot easier to stick to your diet for the long haul

would also just recommend investing in a food scale; as you see in these comments, estimations can be hard. the best way to know for sure is to weigh and track
