Diet management shakes, who can't eat them if they don't taste good?

I've thrown away more than a few products I've ambitiously bought after resolving to go on a diet because they tasted bad. But this time, a friend gave me a diet shake to try, and my eyes lit up the moment I took a sip. It's so rich, you can't tell if it's a shake or powdered rice, and the chewy grains inside make it fun to eat. It's already famous as Flymeal.

Now that I think about it, I remember seeing it at Olive Young..?

Normally, if I drink a diet shake, I get hungry quickly and reach for a snack, but this one is rich in dietary fiber and keeps me full until lunchtime. I highly recommend it to anyone with weak willpower like me who absolutely can't stomach a tasteless diet shake. These days, I drink this instead of dinner and go for a light walk, and it makes me feel much lighter. I think a diet is only sustainable if it tastes good!
