Building Your Own Diet Plan

Is a raw vegan diet healthful over a long period of time, especially with diabetes and high blood pressure? I am trying to switch to a raw vegan diet, but my dietitian insists it is not healthful. Has anybody here tried it long-term, or know anybody who has? I’m wanting to lose a lot of weight, and I’ve been making a lot of salads, with cucumbers, tomatoes, lettuce, green bell peppers, celery, onions, carrots … and then I pour on a bunch of vinegar and lemon juice. It’s tasty, nutritious, and very low-calorie. It seems to be working for me, but my dietitian isn’t happy. And I didn’t even tell you what my primary care physician thinks about my decision to quit all my diabetes and blood pressure medications and just rely on a raw vegan diet instead of the meds … except that I’m going to have to find another primary care physician.
