I know it is ok to have edammame on the fat smash diet but how much in 24 hours?

There's no official limit...just remember portion control.

In East Asia, soy has been used for more than two thousand years as an important source of protein. Soybeans are consumed snacks, vegetables, soups or processed into sweets. As a snack, the pods are cooked in lightly salted water and extracted directly from the pods into the mouth with your fingers.

I made some of these yesterday and just love them. Ive had them in my freezer for some time now. Will be making them more often. I just eat them shelled out when done, or use in my salads.
