Hi there ~
I understand your concerns. I believe there are some case reports of acai being helpful in helping lose weight, however there are only two physiologically possible ways for losing weight. One is to exercise regularly and the other is to eat right. I hope you consult a dietetics specialist as well as an exercise specialist for the same. Also if you think you need medical help
losing weight consulting a qualified doctor or a psychiatrist
will be helpful.
Take care and have a lovely day!
