That's interesting that you find fat more satiating…what do you eat at 750 cal? The problem with an Atkins style food list for me, even with limits on added fats like butter or Mayo, was that the food provided satiety…. but at too many calories for me to lose weight (I regained) and not enough nutrition. Unlikely I was ever satisfied at 750 cal…probably ate double that. In addition to the higher calories…

"While some people believe that fat is the most satiating macronutrient and you can ‘eat fat to satiety’, we know that fat provides very little in the way of vitamins, minerals, and amino acids, which largely influence satiety. Once your blood glucose is stable and you’ve reduced your refined carbs, it may be better to dial back your dietary fat intake so your body can use the body fat it has stored." https://optimisingnutrition.com/car...-carbs-and-fat/

This article started me on the path to finding satiety at a lower fat percentage (which means for me more nutritious low calorie carbs and higher protein.) Mind you, it took a decade before I accepted "keto" wasn’t working for me.
