I need a diet shake recommendation~~^^

Hello~~!!

I started exercising recently because my belly fat kept coming out, but as expected, controlling my diet is the hardest partㅜㅜ

So, I'd like to get some recommendations for diet shakes that are easy to drink in the morning or evening. Are there any that are good in taste and are the right amount for the whole family?

A lot of people around me recommend diet shakes, but I'm having a hard time choosing one because I don't like the artificial chocolate flavor. Could you recommend a diet shake that's filling and filling? This time, I really need to get rid of my belly fat before my clothes get lighter...ㅠㅠ
