Dissecting the China Study
The China Study by Colin Campbell is an interesting and unfortunate example of academic and intellectual dishonesty. Campbell made no attempt to control for his own selective and confirmation bias, cherry-picking only the studies that supported his dietary and nutritional perspectives and ignoring a large (and growing) body of data that consumption of animal products, cholesterol and saturated fat are not only acceptable for foods for humans, but necessary foods for human health.
Denise Minger, Chris Masterjohn and Kurt Harris offer insight into the problems of the China Study. Campbell's intellectual and academic dishonesty are, in a word, astounding.
from the page: "Campbell is now on the advisory board of the Physician's Committee for Responsible Medicine,2 which describes itself as "a nonprofit organization that promotes preventive medicine, conducts clinical research, and encourages higher standards for ethics and effectiveness in research,"3 but whose opposition to the use of animal foods reflects its ties to People for the Ethical Treatment of Animals (PETA) and other animal rights groups.4
Only 39 of 350 pages are actually devoted to the China Study. The bold statement on page 132 that "eating foods that contain any cholesterol above 0 mg is unhealthy,"5 is drawn from a broad — and highly selective — pool of research. Yet chapter after chapter reveals a heavy bias and selectivity with which Campbell conducted, interpreted, and presents his research."

The purpose of this page is to collect a lot of medical research about low-carbohydrate diets in one place, and to make that research understandable to the average person. What you'll find below are abstracts (short summaries) of medical articles. If you click on an entire topic, you'll find several articles, and each article will be followed by an explanation in relatively jargon-free English. Bear in mind, the explanations were not written by a medical professional. There are almost certainly errors in some of them. Please refer to the original article when in doubt, and mail me if you find an error.Pick a topic:

How do you do it?
Here is a 12- step list of what to do. Go as far down the list as you can in whatever time frame you can manage. The further along the list you stop, the healthier you are likely to be. There is no counting, measuring, or weighing. You are not required to purchase anything specific from me or anyone else. There are no special supplements, drugs or testing required.*
1. Eliminate sugar (including fruit juices and sports drinks that contain HFCS) and all foods that contain flour.
2. Start eating proper fats - Use healthy animal fats or coconut fat to substitute fat calories for calories that formerly came from sugar and flour. Drink whole cream or coconut milk.
3. Eliminate gluten grains. Limit grains like corn and rice, which are nutritionally poor.
4. Eliminate grain and seed derived oils (cooking oils) Cook with Ghee, butter, animal fats, or coconut oil.
5. Favor ruminants like beef, lamb and bison for your meat. Eat eggs and some fish.
6. Make sure you are Vitamin D replete. Get daily midday sun or consider supplementation.
7. 2 or 3 meals a day is best. Don't graze like a herbivore.
8. Adjust your 6s and 3s. Pastured (grass fed) dairy and grass fed beef or bison has a more optimal 6:3 ratio, more vitamins and CLA. A teaspoon or two of Carlson's fish oil (1-2 g DHA/EPA) daily is good compensatory supplementation if you eat grain-fed beef or no fish.
9. Proper exercise - emphasizing resistance and interval training over long aerobic sessions.
10. Most modern fruit is just a candy bar from a tree. Go easy on bags of sugar like apples. Stick with berries and avoid watermelon which is pure fructose. Eat in moderation.
11. Eliminate legumes
12. If you are allergic to milk protein or concerned about theoretical risks of casein, you can stick to butter and cream and avoid milk and soft cheeses.
