How much protein per day

.6-.8g per lb of body weight will suffice.

How do you know which end of this range is right for you? I have been following the 1g/lb of lean body mass approach (which falls in the middle of this range) but meeting it is a struggle every day! Is .6 enough during loss to keep me from losing muscle?

You don't need a whole lot. Your muscle cells run on glucose, and so does your brain. The amount of protein found in plant food, like fruit and greens, is enough for most people. You only need protein to repair, not fuel yourself, which is a very common misconception. About 3%-9% of your total caloric intake should come from protein, and that just so happens to be exactly how much is in most plant food.

Most of the studies that I've read with these ranges involve athletes. Personally I wouldn't go under .45 grams per pound while maintaining. Last year I believe there was a study of .6 grams per pound in a deficit maintaining lean body mass. In theory the higher may add muscle but, outside of muscle biopsies who knows.

Real science has provided sufficient data to support these assertions regardless of how vocal and adamant some individuals may be in furthering their distorted belief systems.

I'd recommend 0.8 grams per 1lbs of body mass. You can, if you want, have up to 1.2

I believe the minimum rda is .8 per kilogram of bodyweight. If you exercise (which you should be), it is probably a good idea to at the very least double that. If cutting, triple it.

This post is categorically and fundamentally wrong in pretty much every way.

The poster claiming this has lost, in my estimation based on before/after pictures he has posted, at least 20 lbs of muscle mass while losing weight specifically because of his incredibly low protein intake coupled with an apparent lack of resistance training. This means his body now has significantly more fat mass and less muscle mass than if he had followed more reasonable guidelines.

If you are losing weight, and want to lose fat instead of muscle, do not follow his advice and instead consume the evidence-based recommendation of 1 - 1.4 grams per pound of lean body mass:

that's why in the whole course of human history and human pre-history, there's never been a single group of people who subsisted on gathering only, as opposed to hunting and gathering. And hunter-gatherers, or at least healthy, successful hunter-gatherers, get around 80g protein a day, mostly from animal sources. More than that in some ecosystems (e.g. the Arctic). Neanderthals got 100% of their protein from meat (molecular studies confirmed this); they ate vegetables too but this would have been for carbs and micronutrients.

even gorillas don't rely on plants for all their protein because they eat insects, a lot of insects, and insects are high in protein. Animal protein. And they're much better at digesting coarse vegetation like grass than humans are. In fact all the great apes are omnivores, and the two most closely related to humans (chimps and bonobos) eat mammals as well as insects. Cows and other ungulates can live off a plant only diet because they have four stomachs and can digest the cellulose in grass and other plants, which humans can't digest. Cellulose passes straight through the human digestive tract, and it's known as "fibre" which is necessary in the diet to avoid constipation etc but it provides no actual nutrition.

humans are omnivores and need more protein than you can get on a plant only diet, unless you happen to live in a part of the world where you can grow huge quantities of tofu or pulses and get your protein from them and have access to vitamin B12 suppelements, or live in a post-industrial society where you can have those kinds of foods imported to where you live and buy vitamin B12 supplements in your local shops.

If you want to live off plants, go ahead, but don't lie to yourself or other people about the nutritional needs of humans just to make it suit your decision to eat a plant only diet. Humans can be healthy on a plant only diet so long as they get all the same nutrients that an omnivore gets, which includes eating the same macronutrient profile that an omnivore gets, i.e. a lot more protein than the amount listed above.
