How much protein...?

Fermented soy (or most things fermented) is very good for you. Unfermented soy is very bad for you. All to do with gut and hormone balance which are extremely important. Plus most soy is genetically modified. Beans, nuts and seeds are very heavy in lectins (bad in excess). I respect your aversion to animal products but please, for the sake of your health, switch to a vegetarian diet.

Your protein requirement is linked to your lean weight, not your current weight. Opinions vary, but personally I go by 1 gram per kilo of healthy weight for an averagely active person. Women naturally carry more fat than men. So for now I would look up your weight in kilos at a BMI of 25 and use that as your grams of protein target. Any less and your muscle strength will suffer. Your most important muscle is your heart. Too much protein (say +20%) may drive cancer in susceptible people.

MFP only does calculations as a percentage of total calorie requirement (and the heavier you are, the more calories you require to move around). I do look at the total, but completely ignore the percentages. I set my loss aim at 1 lb per week but in 4 weeks I have lost 8 lbs, even though I slightly exceed their target calories. I eat significantly less carbs and slightly less protein than MFP says. Healthy fats are coconut oil, avocado oil, virgin olive oil (unheated) and butter and cheese (esp goat) and anything else that is low in unsaturated fats. For non vegetarians you can add beef and lamb fat from animals that have only ever been fed on grass and of course wild fish. Vegans and vegetarians typically have diseases linked to inflammation, such as arthritis, diabetes and alzheimers, due to too much Omega 6 and not enough Omega 3. Vegetarian sources of Omega 3 are in the form of ALA which is very poorly processed by the body.

MFP defaults to 15% of your daily intake being from protein. The .8 grams per pound of lean body mass (not total body weight) is a better goal, IMHO. However, as long as you stay above the 15% goal you shouldn't have a problem. Just expect to lose lean muscle mass as you lose weight eating so little protein. That will effectively lower your metabolism over time.

Mine is defaulted to 30% ?? 112 g

Anyway I've heard 1 g per lb of lean body mass. But if you are not doing strength training I don't see why you would need that much. Some other people may know better than me.
