Quotes About Metabolism

My metabolism is very high, and I love sweets and food.

With swimming, I burn a lot of calories. I'm able to eat pretty much anything and it won't affect me. But I don't.

if you cannot control your hunger and appetite, good luck managing your blood chemistry, metabolism, waistline, and, in the bigger picture, the prospect of crippling your brain.

The origin of brain disease is in many cases predominantly dietary. Although several factors play into the genesis and progression of brain disorders, to a large extent numerous neurological afflictions often reflect the mistake of consuming too many carbs and too few healthy fats.

What's more, as we consume carbohydrates we stimulate an enzyme called lipoprotein lipase that tends to drive fat into the cell; the insulin secreted when we consume carbohydrates makes matters worse by triggering enzymes that lock fat tightly into our fat cells.

In the normal process of producing energy, each mitochondrion produces hundreds if not thousands of free radical molecules each day. Multiply that by the ten million billion mitochondria that we each possess and you come up with an unfathomable number, ten

fructose was called the most fattening carbohydrate more than forty years ago by biochemists.

To quote Gary Taubes, "In fact, we can define this mild ketosis as the normal state of human metabolism when we're not eating the carbohydrates that didn't exist in our diets for 99.9 percent of human history. As such, ketosis is arguably not just a natural condition but even a particularly healthful one."28

We can break down fat into specialized molecules called ketones, and one in particular that I've already mentioned—beta-hydroxybutyrate (beta-HBA)—is a superior fuel for the brain.

A purely ketogenic diet is one that derives 80 to 90 percent of calories from fat, and the rest from carbohydrate and protein.

reduce the risk of LDL oxidation—not necessarily levels of LDL itself. A principal player in that risk of oxidation is higher levels of glucose; LDL is far more likely to become oxidized in the presence of sugar molecules that will bind to it and change its shape. Glycosylated

Fat—not carbohydrate—is the preferred fuel of human metabolism and has been for all of human evolution. We

ketones block the apoptotic pathway that would otherwise lead to self-destruction of brain cells.

the ideas presented in this book culminate a century of research questioning the calorie balance model of obesity, and represent a fundamentally different way to understand why we gain weight and what we can do about it.7

People with major metabolic problems, like severe insulin resistance or type 2 diabetes, may benefit from long-term carbohydrate restriction— to 25 percent of daily calories as in Phase 1 or sometimes even lower. Preliminary studies report that some individuals experience remarkable improvements in health by eliminating virtually all carbohydrates on a ketogenic diet.4

Ironically, the standard treatment for diabetes since the 1970s has been a low-fat, high-carbohydrate diet—the same diet that contributed to the problem in the first place! We wouldn't give the milk sugar lactose to someone with lactose intolerance. What's the sense in giving so much carbohydrate to someone who, by definition, has carbohydrate intolerance?

Despite consuming the same total calories on each diet, the participants burned about 325 calories a day more on the low-carbohydrate diet than on the low-fat diet, amounting to the energy expended in an hour of moderately vigorous physical activity. So the type of calories we eat can affect the number of calories we burn.

In a sense, the calorie balance view of obesity is like considering fever a problem of heat balance. It's technically not wrong, but also not very helpful.

Muscles require a constant source of energy just to maintain their mass, so the more muscle you have, the more calories you burn.

Now, here's the key thing you need to know about mitochondria: Like any other sort of engine, they generate energy, but they also generate waste. However, unlike your car engine, which turns gasoline into energy while creating smog, the mitochondria turn food into energy while creating something called free radicals.

Within every cell in your body is a posse of organelles (or miniature organs) called mitochondria

The importance of insulin is becoming more well recognized. Unfortunately, some people are writing books that fail to distinguish between simple and complex carbohydrates. They recommend that people minimize intake of carbohydrates and increase intake of protein, even high-fat, high-cholesterol animal proteins, which is most unwise.

Le cerveau humain exige considérablement plus d'énergie : les 2 % de la masse corporelle que représente le cerveau consomment 20 % de toute l'énergie produite au repos.

Nicardipine is metabolized by the liver, and excretion can be impaired in patients with abnormal hepatic function.
