> Do you have any good sources on the bioavailability of meat vs. plant nutrients? I've tried giving up meat before and have found that I feel noticeably worse both physically and mentally when I don't eat it, even if I eat a lot of plant protein and take supplements.
> I don't know if this simply due to my own unique biochemistry or what, but it's not subtle. I have a fast metabolism, so that may have something to do with it?
For better or worse, it's very easy to end up eating a caloric deficit on a plant-based diet. I'm very glad I use a kitchen scale and small script I wrote to calculate how much kcal/protein/carbs/fat I'm actually getting in comparison to what I should be getting. To put it mildly, plant-based diets take some getting used to.
Protein is important, but beyond 1.4-1.6 grams of protein per kg body weight, your body increasingly relieves itself of any excess. Particularly if you stick to eating low-fat legumes, grains and greens per Esselstyn [1], getting enough protein isn't a concern. In fact, I have to consciously choose low protein foods like potatoes and rice just to ensure I don't get too much protein.
