Ray ~ According to the FAQ's at the top of this forum, you can have all the beans and lentils you desire in Phase 1 (so your hummus and soup are OK). You can have SOY NUTS, TOFU, veggie burgers, tofu burgers, protein shakes (they say make your own with whey protein powder & fruit), yogurt (soy yogurt is recommended for more protein), and egg whites in phase 1.
I like the roasted soy nuts as a snack, but be sure to measure them as servings. You could have kidney beans & brown rice as a dish too. How about an egg white omelette for one meal a day? I wonder if egg beaters are OK for this? hmmm ...
One caviat ~ you can't have soy cheese or other cheeses, like Parmesan or nuts, until phase 2 as per the FAQ's. I read that some found the list of things allowed a bit confusing and inconsistent; guess you just have to do your best, but you really need to get more protein in your plan. Can you eat a bit more often? This phase is only suppose to last 9 days ... then you can add in some fish and lean meats, and nuts, etc.
Now that I see the limitations there are on Phase I of this plan in more detail, I can see why you are having some problems getting in enuff protein; but in Phase II, you add some more back in. Some vegetarians do have the same issue, at times.
Here's the basic plan in a nutshell from another poster ~
Phase I ~ for 9 days, you eat fruits, veggies, brown rice, oatmeal, yogurt, protein in the form of tofu, lots of beans, egg whites, etc -- no meats, white potatoes, white rices, no fish in Phase I. And only water; but Dr. Ian says 2 cups of decaf tea is OK, as is green tea.
After 9 days, in Phase II ~ you reintroduce your body to fish and some of the leaner meats, and nuts. Couple it with 30 mins of excerise in the first phase and bump it up in Phase 2 (to make up for the higher caloric intake). Then you get into Phases 3 and 4 where cheese and some other things are added.
PS ~ Dr. Ian also says you can take a good multi-vitamin as well.
BTW, I am not doing the Fat Smash plan; I can have meat in mine and there are no phases. I just like to read other plans to get ideas and saw your question about protein, and tried to help; so I hope I did a bit ...
