Great that your weight loss has restarted. BMI is useful but not completely accurate, last week I got into the 24’s, I then upped my weight training put on more lean muscle mass which decreased my fat percentage - this put my BMI up to 25.4, I don’t care. I would recommend weight to height ratio

If you list the “restrictive” foods they tend to be made of a combination of sugar, flour and vegetable fats (garbage). These have been engineered by food scientists to hit the sweet spot in humans. If you also review the nutritional content of such foods, they tend to be empty calories, this is psychological food, not physiological. The restrictive list is modern man made, delicious and pervasive. There are loads of alternatives, over 3 days I finished off in third portions an apple pie, with Greek yogurt and peanut butter - this was home made with almond and fibre flour mixed in equal portions for the pasty and Granny Smiths apples (this was part of a 3 course meal, blood sugars the next day on my regime 3. Something). I also within the last week have had chicken pie, about a 5 inch square portion again made with Fibreflour. There are loads of alternatives.
I just added up the individual items I tend to have in a meal. Main (meat or fish, at least 3 veg), nuts seeds around 10 plus, desert 2 to 3 elements. So I have routinely over 15 elements in my meals and plenty of variety - just ask for ideas on the site.
