Need more info! What’s your calorie budget? Sex, age, starting weight, height? What’s your typical dinner? Because oof, I don’t doubt that this has been successful for you in the past but I’m skeptical as to whether or not this’d work for me (32f, 5’4, 138lb). At 1200 calories, I can’t blow more than half my budget on a glass of milk and carb-sugar-heavy muffin… as DELICIOUS as that sounds right now. :’) It’s difficult enough to eat two hearty protein and fiber-rich meals to hold me over for my 18 or 20h fasts.
A super fun treat (they’re so good!) but that’s like a piece of cake a day, my body needs better nutrients or I feel like crap. It’s like the guy that lost all the weight eating just twinkies, anything that has you in a deficit will work, but it’s what it’s doing to your body in the mean time
