Burning Calorie Fat

This “good” fat, researchers said, unlike white fat that makes up most body fat, is active in burning calories and using energy.

Burning calorie fat may seem like science fiction, but a study released found that adults have small blobs of metabolism-regulating brown fat previously believed to exist only in babies and children.

The study, published in Thursday’s issue of The New England Journal of Medicine, showed that brown fat subsisted in adult humans and demonstrated, for the first time, that it is metabolically active.

“The fact that there is active brown fat in adult humans means this is now a new and important target for the treatment of obesity and type 2 diabetes,” said the study’s senior author C. Ronald Kahn, who heads an obesity and hormone action section of the Joslin Diabetes Center in Boston, Massachusetts.

The researchers said that obesity and other metabolic disorders could be treated by stimulating brown fat growth to control weight and improve glucose metabolism.

Brown fat may have a role in regulating body weight metabolism, with higher levels of brown fat helping protect against obesity linked with aging, according to the study.

Younger and thinner patients who had normal blood glucose levels had more brown fat, researchers found. Brown fat was also more active during colder weather, when it plays a key role in burning energy to produce heat.

“Not only did we find active brown fat in adult humans, we found important differences in the amount of brown fat based on a variety of factors such as age, glucose levels and, most importantly, level of obesity,” said lead author Aaron Cypess, a physician at Joslin, which is affiliated with Harvard Medical School.

The researchers analyzed a database of 1,972 patients who had nuclear (PET) or X-ray (CT) imaging scans during a three-year period for a variety of reasons. They found significant brown fat deposits in 7.5 percent of female patients and in over 3 percent of male patients.

“These numbers clearly represent an underestimate, since PET/CT can only detect collections of brown fat cells of a certain size and activity, and could miss smaller and less active deposits,” Kahn explained.

Cypess said the findings “suggest that there is previously unrecognized, heat-generating brown fat in many adults.”

Most of the brown fat deposits were found in the patients’ necks. The researchers tested the tissue of two patients whose scans showed brown fat concentrations in their necks and found that the cells had the protein UCP-1, which is unique to brown fat.

Significant amounts of brown fat may be present in a much larger portion of the population, but may be more spread out and thus not as easily seen on imaging, Kahn said.

Creation of a Comfort food

CHICAGO - A baseball park in Michigan has created an artery-busting hamburger containing 4,800 calories and is daring fans to eat the “snack,” promising a free t-shirt to anyone who succeeds.

In an apparent bid to cook up some comfort food during hard economic times, the West Michigan Whitecaps are offering fans a behemoth dubbed the Fifth Third Burger, named after the team’s ballpark and the meal’s five beef patties, which each weigh one third of a pound (136 grams).

The burger is smothered with chili, salsa, sour cream and a dollop of melted nacho-style cheese — topped off with Frito chips, lettuce, tomato and five slices of American cheese and laid out in a bun made with a pound (454 grams) of dough.

“Besides being unique and large and bizarre, it tastes good,” Whitecaps president Scott Lane told the Grand Rapids News.

“I’m sure there are going to be crazies that come down and try to eat the entire thing.”

In addition to weighing in at more than double the US daily recommended caloric intake, the Fifth Third Burger contains nearly 300 grams of fat, 744 milligrams of cholesterol and more than 10,000 milligrams of sodium, the paper said.

Lane shrugged off the health implications inherent in taking on the Fifth Third.

“At home, people eat healthy. When they come to a game, they might eat a hot dog.”


Calorie Content of Restaurans are now being Counted

A total of 17 restaurant chains and catering companies have agreed to give consumers more information about what they are eating.

They have signed up to strict criteria set out by the Foods Standards Agency (FSA), working with the Department of Health.

They must show the number of calories in each portion in writing that is clear and at least as prominent as the name or price of the product, display calorie information for most food and drink they serve and print calorie information on menu boards, paper menus or on the edge of shelves

By the end of June, 350 outlets across the country will have menus carrying calorie information and more companies are expected to join the scheme in the coming months.

So far, the 17 firms that have signed up are: Wimpy, Burger King, Compass Group UK and Ireland, Co-operative supermarket cafes, ISS Mediclean, KFC, Marks and Spencer Revive cafes, Chessington World of Adventures theme park, Harvester and Scream pubs, Pizza Hut, Pret A Manger, Sainsbury’s cafes, Sodexo, Subway, Unilever staff canteens, Waitrose cafes, 7 Day Catering.

Public health minister Dawn Primarolo said: “People want to easily see how many calories are in the food and drink they order when they eat out.

“This ground-breaking group of companies will help people to know what’s in the food they are eating.

“I want to see more companies and more outlets to help even more people live healthier lives.”

Tim Smith, chief executive of the FSA, said: “We are really pleased that such a diverse range of companies has agreed to work with us by introducing calorie labelling at the crucial point where their customers make a decision about what to eat.

“Our aim is to ensure that consumers have better information so they can make informed choices to improve their diet when eating out, whether that is a snack on the go, a meal in a staff restaurant or at a table being served by a waiter.”

BABY GIRL: A study of 740 first time mothers in Britain shows that whether moms eat breakfast cereal or not might determine whether their bundle of joy is a boy or a girl.

The reason is a mystery, but Mathews speculates that glucose may be key. This type of sugar, converted by the human body into energy, is a by-product of the breakdown of carbohydrates such as those in breakfast cereal. Women who do not eat breakfast tend to have low levels of glucose, and other studies have shown that glucose enhances the growth of male fetuses in vitro.

But it wasn’t only calories that contributed; specific foods also appear to play a role, say researchers. “Prior to pregnancy, breakfast cereal, but no other item, was strongly associated with infant sex,” the researchers write in the journal Proceedings of the Royal Society B. “Women producing male infants consumed more breakfast cereal than those with female infants.”

Matthews notes that low glucose levels may indicate to the body that food is scarce, signaling that it would be more prudent to produce a female fetus, which has been found to need less energy to grow. Scientists have also found that cows, deer and horses produce more male offspring when they have bountiful diets.

Such an intriguing finding will need to be replicated in other populations, such as those in developing nations who are chronically underfed, before any definitive conclusions are reached, according to biologist Virpi Lummaa of the University of Sheffield in England, who was not involved in this research but studies human evolution. Researchers in the future might also survey women about their diets before they get pregnant (while their eating patterns are fresh on their minds) rather than after the fact in their quest to prove whether we are, indeed, what our mothers ate.

The researchers took into consideration variables such as the education, size, weight and age of the would-be moms. But there are other variables, such as temperature, hormone levels, and even frequency of sex, that may contribute. “It remains to be seen whether women with greater nutritional intakes, and higher frequency of breakfast cereal consumption, prior to conception are also those with more active sex lives,” the researchers write.

But the finding may explain a persistent and puzzling drop in the ratio of male to female births in well-fed industrialized nations, a fact that Mathews ascribes to the decline in the proportion of women eating breakfast. She notes that the number of adolescent girls eating breakfast in the U.S. dropped from 85 to 65 percent between 1965 and 1991.

Know How Many Calories You Should Eat

To avoid gaining weight over time, you should aim to burn up as many calories through basic metabolic function and physical activity as you take in. To know whether you’re on track, you need to be able to estimate how many calories you need based on your age, gender and level of physical activity.
The calorie ranges shown in this table allow for the needs of people of different ages within an age group. Adults need fewer calories at older ages. For example, an active 31-year-old man needs about 3,000 daily calories, but an active 50-year-old man needs only about 2,800 calories.

Activity Level and Estimated Calories Burned

Sedentary means you have a lifestyle that includes only the light physical activity associated with typical day-to-day life.

Moderately active means you have a lifestyle that includes physical activity equivalent to walking about 1.5 to 3 miles per day at 3 to 4 miles per hour, in addition to the light physical activity associated with typical day-to-day life.

Active means you have a lifestyle that includes physical activity equivalent to walking more than 3 miles per day at 3 to 4 miles per hour, in addition to the light physical activity associated with typical day-to-day life.

DEFINITION

First Definition

Amount of heat required to raise the temperature of one gram of water by 1°C. It equals 4.18 joules or about 0.004 British thermal units (Btu). It is also called gram calorie or small calorie.

Second Definition

Unit of energy-producing potential of a food (commonly shown as calorie on the nutrition label of the item) is actually a kilocalorie—equal to 1,000 small calories—amount of heat required to raise the temperature of one kilogram of water by 1°C. It equals 4.18 kilojoules or about 4 British thermal units (Btus). It is also called food calorie, kilogram calorie, large calorie, or nutrition calorie.

Do we really have to be afraid of CALORIE?

Calorie is the amount of energy we need in our body everyday. Too much calorie will result to obesity. It is significant that we count the calories we intake so we will know how much calorie we will burn through exercising.

We human being needs calorie everyday to maintain important bodily function such as digestion, heart rate and breathing. People who don’t consume necessary nutrients jeopardies the option of future health complications such as losing bone. Satisfactory is very important for our bodies to preserve an immune system, healthy heart and all other vital bodily processes. The bottom line is that we are required to consume calories to survive; though, the calories must be full of essential nutrients to maintain fundamental bodily functions. Consuming less than recommended caloric intake, then you will eventually lose body weight. If you consume more than your recommended caloric intake then in the end you gain weight.

It takes around 3, 500 calories below your calorie requirements to lose a pound and it takes around 3, 500 calories above your calorie requirement to gain a pound.

Calorie-Content of Fats is over-valued

The calorie value of fats is over-stated because fats, particularly in huge amounts in the diet, may not be totally burned to carbon dioxide and water. Aside they oxidize partly and produce ketones (like charcoal that remains when wood is not totally burned to ashes). Until our kidneys get rid of them, ketones contain appetite. This is why fats are used in some weight loss diets. However, it is possible that the long term presence of ketones from such diets can harm our kidneys and liver, so be careful in using this type of high fat weight loss plan.

Not All Food Calories Used For Energy making

Essential fatty acids (EFAs) include 9 calories per gram, but our body consumes them for structural, hormonal and electrical functions rather than for energy. At high levels of ingestion, EFAs increase metabolic rate and increase fat burn off, resulting in loss of weight.

We Burn Calories at Different Rates

Metabolic rate be different from one person to another, from one time to another in the same individual and differ with the total nutrient mix. Genes, hormones, nutrition, exercise and state of health all affect metabolic rate. Other people are born with a high metabolic rate and never gain weight no matter how much they eat. Thyroid activity affects metabolic rate over a wide range. The slower the rate, the a smaller amount calories are burned and the easier it is to gain weight.

Health status have an effect on Calorie-Burning

The state of our health change our metabolic rate. If we fevers and infections, much more energy is burned than when a person is healthy. In late stages of cancer, tumors eat most of the body’s stores of energy resulting in loss of weight. Stress increases the body’s fat burning rate. Some people lose 10 pounds in just a few days of serious worry. Other stresses also stimulate the body’s fat burning mechanisms.

Extra Mental Activity burns Extra Calories

The span of time per day spent awake makes a difference as we burn more calories when we are awake than when we are sleeping. The level of mental activity affects the use of calories. Our brain, although it is only 2 percent of the body’s weight uses 20 percent or more of total calories burned by our body.

Environment Affects Calorie Usage

Environmental conditions effect the rate at which calories are used. Our body responds to changes in temperature, season and climate, raising metabolic rate to keep body temperature constant. Clothing conserves more or less calories, depending on what it is made from, how thick it is and how much of our body we cover with it. Our body loses more heat swimming in cold water than when surrounded by air of the same temperature, because air conducts body heat away less rapidly. Shivering also increases fat burning.

Hunger and satiation factors also influence whether the foods we eat keep us fit or fat. Different foods are digested, absorbed into our body, and made available for use at different

For who says that  “A calorie is a calorie” in this perspective mean to suggest that macronutrient proportions are extraneous to weight management. All that substances are the total number of calories consumed, in spite  of whether the plurality comes from fat or carbohydrate.
It sounds reasonable, but it’s actually it’s wrong. A calorie is not a calorie, in more than one sense. Carbohydrate, fat and protein calories are indeed equal by label in terms of their energy content, but the body processes each in a distinct way, and these differences have real propositions for weight management. In connection, food calories of all categories may have very different effects on the body depending on when they are eaten and what they are eaten with. Below are the  five particular reasons why all calories are not equal.
1. The energy cost to metabolize fat, carbohydrates and protein are not the same
The body must consume energy to digest, take in and metabolize the energy in food. It so happens that the body consumes dissimilar quantities of energy to process different energy-containing nutrients. In general,  additional energy is required to process protein than carbohydrates, and additional energy is required to process carbohydrates than fat.
2. Calorie constraint slows metabolism
The major problem with using linear calorie equations for fat loss is that the lesser calories you intake, the lesser calories your body burns. Therefore, if, based on the 3,500-calorie rule mentioned above, you make a decision to cut your daily energy consumed by 500 calories in hopes of losing a pound a week (500 calories/day x 7 days = 3,500 calories), you will most likely find that you do certainly lose a pound in the first week but fewer  in each following week. This incident is believed to represent a metabolic adaptation to prevent malnourishment. Your body exactly runs cooler to conserve the reduced number of calories you’re eating, thus effectively increasing the value of each calorie.
3. Protein decreases appetite
Protein in general decreases appetite more per calorie than fat and carbohydrate. Thus ,a person who increases his daily protein consumed without making any conscious attempt to eat less is likely to eat less in any case due to reduced appetite. This is one more important sense in which protein, carbohydrate and fat calories are not equal.
4. Fiber decreases calorie amalgamation
Fiber is a form of carbohydrate that contributes to satiety without contributing calories, because it is not being absorbed into the body. as a result, a 100-calorie high-fiber food will decreases appetite and succeeding eating more than a 100-calorie low-fiber food. Similarly, a person who increases his daily fiber consumption without making any conscious effort to eat less will wind up eating less anyway due to reduced appetite. Thus, a calorie inside a high-fiber food is not equal to a calorie inside a low-calorie food-yet a fourth way in which “a calorie is not a calorie.”

Food hampers from food banks were found to be deficient in nutrients or calories, and may not do much to promote the health of the deprived in the province, researchers from University of Ontario said.

The study available in Canadian Journal of Public Health, examined 180 food hampers, sourced from a well established food bank located in southwestern Ontario. The finding revealed that 99 per cent of the hampers, meant to last three days, contained calories sufficient for only 1.6 days.

When comparing the findings against the stipulations of the Canada food guide to healthy eating ,the hampers were found to fall short of requirements in four food groups, having met the requirement only in the ‘grain and cereal group’. The diet did not include enough dairy and meat products, fruits and vegetables, or vitamins and minerals like vitamin B12 and calcium.

The food banks seem to be the only resort to an estimated 820,600 Canadians, of whom 40% are children. The prolonged shortfall in calories and nutrients could cause long term health problems, researchers said.

However, food banks are not to be blamed for this situation, researchers said. The food banks rely on donations and services from volunteers. The need of the hour is to put government policies in order and address the issue at the government level, so that food banks are better equipped to spruce up the quality of food hampers.

Cutting calories from you diet could be good for your brain as well as your waistline.

Researchers in Germany put a group of people aged about 60 on a diet which cut their calorie intake by up to 30%.

Another group had a diet high in unsaturated fatty acids - foods like olive oil and fish also thought to be linked to memory - while a third control group was on a normal diet.

In earlier experiments using rats, a diet low in calories and high in unsaturated fatty acids had shown an ability to boost results on memory tests.

“In the human test, the group on the restricted-calorie diet showed an increase in verbal memory scores whereas the other two groups did not,” according to the research published in the journal Proceeding of the National Academy of Sciences.

“A restricted-calorie diet increased the memory in a group of elderly men and women, confirming benefits previously shown in animal testing.”

The research, done at the University of Munster, also found decreased levels of insulin in those on low calorie diets, along with reduced levels of inflammation markers in their blood.

“The results offer a route for exploring the role of insulin and inflammation on ageing-related cognitive decline,” the authors also say.

The Center for Science in the Public Interest called on government agencies to test industrial chemicals, food additives and environmental pollutants on rodents for three years instead of the customary two and to begin the testing in utero. Scientists recently reported that animal studies of shorter duration may miss toxic effects. . . .Developers of assisted-living facilities in Mexico are wooing American retirees with rates as low as $1,100 a month, the Dallas Morning News reported, but the facilities are largely unregulated. . . .A growing number of countries in Africa, Asia and Europe are criminalizing H.I.V. transmission and exposure, according to a new report by the International Planned Parenthood Federation, which says criminalization undermines public health efforts to fight AIDS. . . .Congress may introduce legislation requiring calorie labeling at all chain restaurants, but an article in the online edition of Newsweek questions whether Americans will really change their eating habits. . . . Every American should have access to comprehensive tobacco cessation services by 2020, said a group of business, health, government and labor leaders said. Seventy percent of smokers want to quit but only 1 in 50 employers currently provides workers with cessation treatment.
