Smelling your food makes you fat ... read more
July 5, 2017
Researchers developed ways to temporarily eliminate the sense of smell in adult mice, and discovered that those mice that lost smell could eat a high-fat diet and stay a normal weight, while littermates that retained the sense of smell ballooned to twice normal weight. Supersmellers gained more weight than did normal mice on the same high-fat diet. Smell-deficient mice burned excess fat instead of storing it, suggesting a link between smell and metabolism.

Genome sequence of a diabetes-prone rodent ... read more
July 5, 2017
Sequencing the genome of the sand rat, a desert rodent susceptible to nutritionally induced diabetes, revealed an unusual chromosome region skewed toward G and C nucleotides. This region includes the Pdx1 homeobox gene, a transcriptional activator of insulin, which has undergone massive sequence change, likely contributing to diabetes and adaptation to low caloric intake, implying that mutation rate varies within a genome and that hotspots of high mutation rate may influence ecological adaptation and constraint.

June 28, 2017
Mildly stressing muscle metabolism boosts levels of a beneficial hormone that prevents obesity and diabetes in mice, according to a new study. The findings show that triggering ER stress in mouse muscle cells causes them to produce and secrete significant amounts of the anti-diabetic hormone fibroblast growth factor-21 (FGF21), which then has widespread beneficial effects on whole-body metabolism.

June 20, 2017
Abdominal obesity, or fat that accumulates around one's stomach and abdomen, has long been considered to pose a high health risk in individuals. Hence, measurement of abdominal fat helps predict propensity to disorders caused by excess weight in the abdominal area. In a new paper, researchers propose a new technique to evaluate abdominal obesity by estimating the thickness of subcutaneous fat.

Genes and the environment? Factors, patterns that lead to childhood obesity risk ... read more
June 16, 2017
A factor that has been linked to childhood obesity is restrictive feeding practices by primary caregivers, the implication being that it may interfere with a child's ability to learn to self-regulate food intake. When a child is overweight, parents tend to use more controlling, restrictive feeding practices. A new study is showing that a child's genetics, related to emotion and cognition, may also play a role in this pattern.

Molecular pilot light prepares body's heating system for the cold ... read more
June 14, 2017
Researchers detail a molecule that acts as a molecular pilot light required to turn on the brown fat furnace. Brown fat burns sugar and fat to produce radiant heat in the body. These cells are of interest because some of the sugar and fat they burn is stored in the body and might otherwise lead to increases in white fat, the form that increases in obesity.
