Debunking conventional dietary wisdom.

Much more at the link, worth reading...

Fat Head - This Is What We’re Up Against, Part Two:
"The following is a transcript of an online debate between me and someone who works at a medical center and is either a nutritionist or has great respect for the advice they dole out. This should give you an idea of what sick people are being told about diet. My mom received the same advice from a nutrionist, but between my lectures and the books by Drs. Eades & Eades, she was persuaded otherwise.

Nutritionist comments are in italics, mine are plain text.

it’s not wise to cut grains out completely. your body needs varieties of different foods, grain included.

Humans lived without grains for 99% of their time on earth. Many native cultures still live without eating grains, which require processing to be edible. On what are you basing your claim that it’s “not wise” to cut out grains completely? (I have, and all that’s happened is several ailments have gone away.)

well good for your individual results. humans have been eating grains for at least 10,000 years, some evidence found it going way further back. granted it only seems like a blink of the eye, but it a significant amount of time nonetheless.

basically you need carbs to function. you need them for your brain and also to exercise. i’m not saying go out and eat a bunch of white bleached and enriched bread, just eat healthy grains.

Evolution doesn’t work that quickly. Some humans have adapted to grains, but many have not. No humans NEED grains to be healthy, and grains can have negative effects on health. The lectins in grains can lead to autoimmune diseases, to name just one. Nor do we need carbohydrates to exercise (I exercise frequently) or for brain function (I write, do standup comedy, and program software all without benefit of carbohydrates other than vegetables). Look up glocuneogenesis.

you actually do need carbs for lots of things, including the central nervous system, the kidneys, brain and muscles (including the heart). you need it cause it’s your main source of energy. without carbs your body will consume protein from your muscles. you also get carbs from fruit and veggies. and again, i’m not saying go eat a bunch of refined carbs, but brown rice, whole grain pasta, and multigrain breads should be a moderate part of your diet.

With all due respect, you’re simply stating an opinion with no facts to back it up. If you consume enough fat and protein, your body will not digest your muscles. I’ve gained quite a bit of muscle since cutting carbs. Carbs are the “main source of energy” as a matter of convenience in grain-growing societies, not as a biological necessity. Most of your body will happily burn fat for fuel — that’s why your body stores energy as fat. (Kind of makes sense, doesn’t it?)

your body will burn muscle and fat as a last resort, it’s a survival mechanism. and with all due respect, you don’t know my educational background, therefore are not qualified to call my opinion just that. an opinion, and with no facts nonetheless. i don’t know if you’re promoting this film for someone or if it’s your film, but arguing on youtube is not a good way to endorse a product.

What is your scientific basis for the “last resort” theory? Without fat or protein, you’ll die. Without carbs, you’ll live just fine, as many hunting and fishing tribes throughout history did. My ancestors lived in Ireland. Pre-agriculture, how did they manage to get all that “essential” carbohydrate? No potatoes, no grain farming, no wild fruits or vegetables except in season. The idea that we evolved to “need” grains and starches a mere few thousand years later is absurd..."
