Your Questions About Energy Sources For The Body

admin answers:

Most low energy foods are also metabolized faster. The reason is that it takes less energy to metabolize them. It is like choosing between straw or logs as a source of fire material. The straw is going to be much easier to ignite, even though it burns faster and has less energy than the logs do. In terms of food it is the difference between carbohydrates and fats. Fats are the way animals store calories and it takes a lot of energy to metabolize them. Sugars are metabolized very easily. However there are other factors when humans are taken into account. “Thrifty genes” are a mutation which turns carbohydrates to fat rather than turning them into energy immediately. It is a useful adaptation to an existence where food is in abundance for a very limited amount of the year. It helped the Native American Pima people to exist on a diet of corn in an arid environment. They gained weight rapidly after the corn harvest and it helped them to survive the rest of the year. Tragically this adaptation can become life threatening if these sorts of people are exposed to a steady diet of carbohydrates. The Pima are now on a western diet of snack foods and are the most grossly obese people on earth. The rate of diabetes is extremely high and life expectancy has decreased dramatically. Personally I probably have mongolian ancestors and these people adapted to a diet of nearly all animal products because the Asian steps were technically an arctic desert. The only vegetation available supported their herds of yaks and sheep, so there were nearly no carbohydrates in their diet. They had very “unthrifty” genes and high metabolisms which enabled them to enjoy diets high in fats and protein. I eat very limited amounts of carbohydrates and a fair amount of fatty foods. Despite this, I don’t gain a lot of weight. All people are unique in the way they metabolize food and it is unwise to use “blanket” statements regarding nutrition. Unfortunately this kind of reasoning is universal in a market driven society and can lead to confusion in its attempts to maximize profit by fitting all consumers into a single category.

Glucose, lipids, and proteins

admin answers:

Carbohydrates. While fats and alcohol will give you more energy/ gram, they are also worst for you, and the energy doesn’t last long. Carbohydrates on the other hand will give you longer lasting energy. Stick with complex carbs such as the ones found in whole grains, dark vegetables, and lentils/beans. Protein will also give you energy and helps you feel full longer so you won’t crave simple carbs.

I think you meant to ask “What are 2 sources of energy for the body besides fat?”

The two other sources are carbohydrates (complex sugars) and proteins.
