I’ve never fully lost my appetite after starting my fasting lifestyle. I will honestly say that my portions has gotten much smaller as time went on. To answer your question it’s normal to have a small appetite as you continuously fast and make it a lifestyle change. An example is like you eating a bbq drumstick and a nice scoop of mashed potatoes and you’re full lol. In the past you may eat a 2nd drumstick with broccoli on the side. Your body adjusts over time with your reduced eating and lifestyle.
