From Dave Asprey:
Here are the main things to understand. This is what I distilled from reading over 150 nutrition books, countless papers online, and spending an evening a month for 10 years with some of the world's top health and nutrition researchs, and self-experimenting for 15 years.
- Dietary fat - including saturated - does not cause heart disease.
- Carbohydrates do, because of their effect on the hormone insulin. The more easy to digest and refined they are, and the more fructose they contain, the more they damage your health. They also feed low grade fungal infections.
- Sugar and high fructose corn syrup are particularly bad because they combine glucose, which raises insulin, and fructose, which damages the liver and ages your tissues.
- Starches, sugars, and carbohydrates are the likely dietary causes of cancer, Alzheimer’s, and dozens of other degenerative diseases.
- Obesity is not caused by eating too much or from not exercising enough. It is a disorder of excess fat accumulation caused by hormones influenced by diet.
- Eating extra calories does not cause you to get fatter. Eating extra sugar does.
- Exercise does not make you lose excess fat; it makes you hungrier. More muscle makes you lose fat only if your diet-influenced hormones are working.
- You get fat when there is an imbalance in the way hormonesregulate fat tissue and fat metabolism. You get fat when more fat gets stored than is mobilized and used for fuel. You get lean when you fix the hormone imbalance.
- Insulin is the primary regulator of fat storage. When insulin levels are high, you get fat because you store extra calories. When insulin is low, you use fat from your tissues as fuel.
- Carbohydrates make you fat by raising insulin, increasing hunger, and decreasing your metabolic rate and exercise levels.
- Cholesterol is a protective response to toxin exposure and a substrate for brain and hormone formation. High LDL is evidence of toxins in our food or a chronic low level infection.
