Finally, we acknowledge that the lack of a control group and the small sample size are probably a limitation of this study and further larger case—control studies would be required to confirm our results. In addition, the morning glucose tolerance was found to be impaired when subjects were consuming 1 meal per day compared with 3 meals per day [ 29 ].

Caloric restriction and inflammation markers -

This might be circumvented by finding the molecular levers that mimic caloric restriction CR in humans.

They also found that a gene called PLA2G7 was an important mediator of these processes. Of the 32 participants, 14 were of healthy weight BMI: To search for anatomical changes in the immune system thymus organ in response to CR, the Yale scientists took MRI measurements of the thymus from each participant before and after 2 years of CR.

The researchers also examined how CR changed gene activity in fat tissue. Based on their findings, the researchers studied a gene called Pla2g7 in mice.

In rodents, extension of lifespan by CR has been associated with maintaining white blood cell production from the thymus. The thymus is an immune system gland that specifically produces white blood cells.

Interestingly, aging of the thymus precedes the aging of other organs, with increased fat accumulation and loss white blood cell production. When calories are restricted, the body switches from utilizing glucose to utilizing fat as energy, which leads to fat loss.

As the body adapts to CR, the immune system also adapts by modulating fat tissue function. These changes could have beneficial effects on longevity and quality of life.

To determine how CR may improve the inflammatory profile of fat, Spadaro and colleagues measured genes from the abdominal fat tissue of participants. They found that gene activity changed after one year of CR and was maintained into the second year.

The changes were not the same as in rodents but similar to those that occur after bariatric surgery or in response to consistent physical activity.

Specific changes in gene activity from human fat tissue in response to CR included genes associated with insulin signaling, suggesting enhanced insulin sensitivity. CR also increased genes associated with ketone body transport and longevity. Overall, the changes in gene activity indicated that CR elicits an anti-inflammatory effect that may improve fat tissue metabolism.

Since one of the genes inhibited by CR in fat tissue was PLA2G7 in participants, Spadaro and colleagues investigated this gene further in mice. In mice with genetically deleted Pla2g7 mouse version of human PLA2G7 , immune system activation was reduced.

These mice were also partially protected from a high-fat diet-induced weight gain, increased fat, and fatty liver disease. Chronic whole-body inflammation during aging is associated with age-related functional decline. To study this, Spadaro and colleagues measured changes in gene activity in aged analogous to 70 year old humans mice without Pla2g7.

Deletion of Pla2g7 in aged mice decreased inflammation, particularly the inflammation associated with visceral fat tissue. Inflammation has been implicated in the age-related shrinkage of the thymus.

The Yale researchers showed that deleting Pla2g7 in aged mice prevented this from happening. Based on these mouse studies, the authors propose that the reduction of PLA2G7 by CR in humans might contribute to better fat tissue metabolism, lower inflammation, and reduced thymus shrinkage.

Overall, the findings demonstrate that CR changes an entire gene activity pattern, promoting immune function and reducing inflammation. Google Scholar. Beasley, L. Inflammation and race and gender differences in computerized tomography-measured adipose depots.
