Yerba Mate If you have free time you should read about it. Its so cool. My boyfriend got me a gourd and straw for mate a few years ago for my birthday and i loved reading the culture around it.
I would really recommend customizing your diet to you. Hopefully you are keeping some sort of track of what you've been eating (or you can remember) I know for me that I don't lose as much weight with tomatoes, oranges, and shrimp. And I lose the most weight with beef and asparagus. And I also lost a lot if I drank a lot of green tea and began my morning with yerba mate instead of coffee. You can make an yerba mate lemonade if its a little bitter for you using stevia lemon juice and the mate tea.
good luck! it just takes some tweaking... keep us updated!
