Problem. The diet with 1090 calories works out to about 92 grams of carbohydrate a day at the given macro nutrient percentages and the 725 calorie diet comes to about 85 grams of carbohydrate a day. Those amounts of carbohydrate are both way too high for a lot of people's bodies to be able to enter ketosis or begin burning fat for fuel and would simply be what Gary Taubes described as semi-starvation diets. High enough carbs to keep the body trying to burn carbs for fuel while hormonally unable to access its own fat storage to make up the calorie deficiency to meet the brain and body's needs. Not good. At that rate might have to resort to burning muscle protein to make glucose for brain and body since the body's fat can't be accessed as fuel or to produce ketones which could otherwise fuel the brain. If I were designing a diet intended to mimic fasting but while allowing the comfort of some food, I'd advise ditching those carbs in favor of fat while keeping the protein level low since both carbohydrate and to some extent protein (but not really fat) elevate insulin which as part of its job signals the body to burn glucose instead of fat. Actual fasting lowers insulin and so should this idea for a diet, so it should much more closely mimic fasting than the higher carb one.
