Protein in general is a filling nutrient, and we can create a protein powder for you that can help with your appetite. We can include casein protein in it as well, which is a slow digesting protein source. Overall, the blend will be filling for the amount of calories that it has.
Keep in mind though that a lower calorie serving of protein powder by itself isn't comparable to an entire meal in how full it will make you feel. To an extent, calories are needed to curb appetite and hunger. If you want your shake to be more satiating, try pairing it with some other healthy foods such as fruits, vegetables, whole grains, and dairy.
