Mathematical Equation Calculates Cost of Walking for First Time

Why do tall people burn less energy per kilogram when walking?

Any parent that takes their kid out for a walk knows that children tire more quickly than adults, but why is that? Do kids and small adults walk differently from taller people or do they tire faster for some other reason? Peter Weyand from Southern Methodist University, USA, is fascinated by the effect that body size has on physiological function.

Intestinal Bacteria Drive Obesity and Metabolic Disease in Immune-Altered Mice

100304142232-large

New research finds that mice lacking a gene called TLR5 have an altered ability to recognize and control bacteria in their intestines, leading them to develop obesity and insulin resistance.

Increased appetite and insulin resistance can be transferred from one mouse to another via intestinal bacteria, according to research being published online by Science magazine.

Tiny Tongue of a Fruit Fly Could Offer Big Clues in Fight Against Obesity, Researcher Says

100211121804-large

It is proven that the ‘clock’ that influences Drosophila’s decision to eat or not to eat is found inside the taste sensing cells and has a very direct link to its eating habits.

The tiny tongue of a fruit fly could provide big answers to questions about human eating habits, possibly even leading to new ways to treat obesity, according to a study from a team of Texas A&M University researchers.

Some Morbidly Obese People Are Missing Genes, Shows New Research

100203131401-large

A small but significant proportion of morbidly obese people are missing a section of their DNA, according to new research.

A small but significant proportion of morbidly obese people are missing a section of their DNA, according to research published February 3 in Nature. The authors of the study, from Imperial College London and ten other European Centres, say that missing DNA such as that identified in this research may be having a dramatic effect on some people’s weight.

C. elegans.

If worms are any indication, all the sugar in your diet could spell much more than obesity and type 2 diabetes. Researchers reporting in the November issue of Cell Metabolism, a Cell Press publication, say it might also be taking years off your life.

Eating a meal quickly, as compared to slowly, curtails the release of hormones in the gut that induce feelings of being full, according to new research.

According to a new study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM), eating a meal quickly, as compared to slowly, curtails the release of hormones in the gut that induce feelings of being full. The decreased release of these hormones, can often lead to overeating.

Phytochemicals In Plant-based Foods Could Help Battle Obesity, Disease

091021144251-large

In a small study of 54 young adults, UF researchers found eating more plant-based foods, which are rich in substances called phytochemicals, seems to prevent oxidative stress in the body, a process associated with obesity and the onset of disease

The cheeseburger and French fries might look tempting, but eating a serving of broccoli or leafy greens first could help people battle metabolic processes that lead to obesity and heart disease, a new University of Florida study shows.

Aging Muscles: ‘Hard To Build, Easy To Lose’

090911103807-large

New research may explain the ongoing loss of muscle in older people, whose arms and legs become thinner as they age

Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which decreases strength and increases the likelihood of falls and fractures. New research is showing how this happens — and what to do about it.

New Evidence That Vinegar May Be Natural Fat-fighter

090622103820-large

Found in many salad dressings, pickles, and other foods, vinegar could help prevent accumulation of body fat and weight gain, scientists report.

Researchers in Japan are reporting new evidence that the ordinary vinegar — a staple in oil-and-vinegar salad dressings, pickles, and other foods — may live up to its age-old reputation in folk medicine as a health promoter. They are reporting new evidence that vinegar can help prevent accumulation of body fat and weight gain.

Mice fed on a diet high in polyunsaturated fatty acids can sprint faster

Between the 1932 and 2008 Olympic Games, world record times of the men’s 100m sprint improved by 0.6 seconds due to improved training techniques and technological advances. Imagine if this improvement could be achieved by a simple change in diet. Scientists at the Research Institute of Wildlife Ecology in Austria have managed to achieve an equivalent feat in mice fed on a diet high in polyunsaturated fatty acids.
