Quotes About Metabolism

The very act of eating can be exhausting; it takes a lot of energy to digest food. When the body is freed from that chore, it naturally feels lighter and much more vibrant.

The body responds to a calorie deficit by slowing down the metabolism and burning muscle tissue. That leads to weakness, sluggishness, slow times. In girls, it can also result in cessation of menstrual periods, which in turn leads to loss of bone density and frequent stress fractures.

I had just 15 days to work on my body for the climactic fight of 'Bodyguard.' And I would work on every muscle of my body two/three times a week. I would have developed a superb body if I had three months, but squeezing it into 15 days can be harmful. Also, as you grow older, your metabolic rate slows down.

Every pound of muscle burns approximately 50 calories every day, just doing nothing.

Guys like me can put on 10-15 pounds in a week.

The only show I ever really wanted to do was 'SNL.' It was some sort of merging of my talent and my metabolism. It suited who I am and what I do really well, though whatever I was thinking it was, it kept mutating and growing. At first, I didn't even know that the cast would be the thing everybody talked about. We thought it would be the hosts.

I've always had an athletic frame, both my brother and I inherited it from our dad. All three of us are tall, with broad shoulders, muscular legs and a fast metabolism.

I do absolutely nothing, actually, believe it or not. People will probably hate me for saying that, but I guess I'm one of those lucky horrible people who, no matter what I eat, I don't gain a pound. My whole family is just like that. They're all skinny and tall, and I guess, so am I.

compared to that of great apes, the reduction in human gut size saves humans at least 10 percent of daily energy expenditure: the more gut tissue in the body, the more energy must be spent on its metabolism.

In 1995 Leslie Aiello and Peter Wheeler proposed that the reason some animals have evolved big brains is that they have small guts, and small guts are made possible by a high-quality diet. Aiello and Wheeler's head-spinning idea came from the realization that brains are exceptionally greedy for glucose—in other words, for energy. For an inactive person, every fifth meal is eaten solely to power the brain.

When we eat, our metabolic rate rises, the maximum increase averaging 25 percent. The corresponding figures for fish (136 percent) and for snakes (687 percent) are vastly higher, showing that humans pay less for digestion than other species, presumably due partly to our food being cooked. But the cost of digestion is still significant for humans and can be reduced or raised depending on the food type.

Assessing the energy value of foods is a difficult technical problem. Nutritionists cannot calculate the value of foods directly because foods are too complicated in their composition and structure, and digestive systems treat different foods in different ways. So instead of making precise calculations of exactly the number of calories people can obtain from a given food, nutritionists make rough guesses.

Homo sapiens, the brain accounts for about 2–3 per cent of total body weight, but it consumes 25 per cent of the body's energy when the body is at rest. By comparison, the brains of other apes require only 8 per cent of rest-time energy.

En Homo sapiens, el cerebro supone el 2-3 por ciento del peso corporal total, pero consume el 25 por ciento de la energía corporal cuando el cuerpo está en reposo.

The fact is that a jumbo brain is a jumbo drain on the body. It's not easy to carry around, especially when encased inside a massive skull. It's even harder to fuel. In Homo sapiens, the brain accounts for about 2–3 per cent of total body weight, but it consumes 25 per cent of the body's energy when the body is at rest.

Never forget that you are not in the world; the world is in you. When anything happens to you, take the experience inward. Creation is set up to bring you constant hints and clues about your role as co-creator. Your soul is metabolizing experience as surely as your body is metabolizing food

And what is breath? It is the carbon dioxide and oxygen that come from the metabolism of every cell in that stranger's body. That is what you are inhaling, just as other people are inhaling your breath. So we are all constantly exchanging bits of ourselves—physical, measurable molecules from our bodies.

Ya sea que lamentes algo de tu pasado o te preocupes por algo del futuro, estás provocando cambios en tu cuerpo. En otras palabras, pasas gran parte de tu vida metabolizando tiempo. (...)¿qué pasaría si no tuvieras una historia? Tu vida sería mucho más simple y más natural. No tendrías una imagen pública que defender. No tendrías miedo del mañana porque sin una historia que seguir aceptarías cualquier experiencia y la dejarías ir.

The downside of aging is a slower metabolism and achy joints.The upside is a knowledge of self that prevents one from behaving like a baboon.

most expensive in the body, second only to the heart. Neurons may be small, but they're costly to make and maintain, consuming about ten times more energy relative to their size than other cells.

I could eat absolutely whatever I want, whenever I want and I won't really gain any weight. I'm going to be 25 in March, and I've never weighed over about 64 pounds in my entire life.

One of the difficulties for me is that I'm naturally very skinny, so the problem that I have is trying to keep weight on, put weight on. I have to eat six, seven times a day, and I have to have a lot of carbohydrates to try and fatten me up so I have something to turn into muscle.

If you look at body fat, it seems to increase with age, even though your weight does not. That's a physiological fact of aging, they say. Heck it is. It is an adaptive effect of aging.

My advice is to give up stevia, aspartame, sucralose, sugar alcohols like xylitol and malitol, and all of the other heavily-used and marketed sweeteners unless you want to slow down your metabolism, gain weight, and become an addict.
