The raw food vegan diet is a very, very difficult one to follow. To do it healthfully, you really have to be careful about every little thing that you are eating to ensure that you are getting the proper nutrients and getting enough protein. Protein is a big concern with the raw food diet.
With how stringent this plan is, I would not commit to it under the pressure of someone else...only on my own convictions. It isn't going to be something that you can stick to, if your beliefs and convictions are not leading you to do so. It is more than just a diet...it is a very strict lifestyle-where you are eating NO animal products (such as a vegan does-no cheese, eggs, meat, etc. or byproducts in ANYTHING) but also you are going RAW at the same time...which makes it 20x harder, because there are a lot of vegan products out there (soy/tofu fake meat products, soy/tofu dishes etc.) that you are not going to be able to consume as well because you are going raw.
I won't kid you...it is one of the hardest lifestyles out there, and you aren't going to be able to live like that under the pressure of someone else alone.
