This is my second purchase. Besides being spill proof and convenient (I don't need to mix with water or swallow with water), I find that it helped me not want to snack as often. I feel full after eating a smaller portion than I used to eat for my meals. I also noticed my visits to the toilet are smoother.
Here's the best part: Recently I tried on an old pair of shorts. It used to be very hard to zip and button up and created a massive muffin top i had to hide with a big loose tee. This time it buttoned up easily and sat comfortably on my waist! Not much of spillage of belly fats even when I sat down! Also noticed better energy during the day, so I believe it's helping my overall health too.
