Obesity raises the risk of gum disease by inflating growth of bone-destroying cells ... read more
November 12, 2021
Chronic inflammation caused by obesity may trigger the development of cells that break down bone tissue, including the bone that holds teeth in place, according to new research that sought to improve understanding of the connection between obesity and gum disease. The study, completed in an animal model and published in October in the Journal of Dental Research, found that excessive inflammation resulting from obesity raises the number of myeloid-derived suppressor cells (MDSC), a group of immune cells that increase during illness to regulate immune function. MDSCs, which originate in the bone marrow, develop into a range of different cell types, including osteoclasts (a cell that breaks down bone tissue).
A newly discovered genetic link to non-alcoholic inflammatory liver disease ... read more
November 10, 2021
Researchers have shown that albino mice of the C57BL/6 line are highly susceptible to developing the inflammatory liver condition non-alcoholic steatohepatitis (NASH) when fed a high cholesterol diet. The albino mice carry a mutation in the tyrosinase gene leading to a deficiency of melanin synthesis. NASH is a serious illness in humans, and the identification of the involvement of tyrosinase in NASH development will guide future research into this condition.

Researchers have uncovered a molecular mechanism behind why obesity can lead to hair thinning. They found that stem cells within hair follicles in mice given a high-fat diet behaved differently from those in mice with a standard diet. Inflammatory signals in the stem cells led to these differences, ultimately resulting in hair thinning and loss. These fascinating data shed light on the complicated link between obesity and organ dysfunction.
Researchers call for a focus on fitness over weight loss for obesity-related health conditions ... read more
September 20, 2021
The prevalence of obesity around the world has tripled over the past 40 years, and, along with that rise, dieting and attempts to lose weight also have soared. But according to a new article, when it comes to getting healthy and reducing mortality risk, increasing physical activity and improving fitness appear to be superior to weight loss. The authors say that employing a weight-neutral approach to the treatment of obesity-related health conditions also reduces the health risks associated with yo-yo dieting.
Meds, surgery may help obesity-related high blood pressure if diet, exercise fall short ... read more
September 20, 2021
Being overweight or having obesity, weight that is higher than what is considered healthy for an individual's height, is a major risk factor for high blood pressure. A healthy diet, more physical activity and less sedentary time are recommended to reduce blood pressure for people who are overweight or have obesity; however, evidence of long-term weight loss and sustained blood pressure reductions from these lifestyle changes is limited. New weight-loss medications and bariatric surgery have shown benefits in both long-term weight loss and improved blood pressure, which can reduce the long-term, negative impact of high blood pressure on organ damage.

Scientists claim that overeating is not the primary cause of obesity ... read more
September 13, 2021
A perspective article challenges the 'energy balance model,' which says weight gain occurs because individuals consume more energy than they expend. According to the authors, 'conceptualizing obesity as a disorder of energy balance restates a principle of physics without considering the biological mechanisms underlying weight gain.' The authors argue for the 'carbohydrate insulin model,' which explains obesity as a metabolic disorder driven by what we eat, rather than how much. *Public health messaging exhorting people to eat less and exercise more has failed to stem rising rates of obesity and obesity-related diseases. *The energy balance model, which says weight gain is caused by consuming more energy than we expend, "restates a principle of physics without considering the biological mechanisms driving weight gain." *The carbohydrate-insulin model makes a bold claim: overeating doesn't cause obesity; the process of getting fat causes overeating. *The current obesity epidemic is due, in part, to hormonal responses to changes in food quality: in particular, high-glycemic load foods, which fundamentally change metabolism. *Focusing on what we eat rather than how much we eat is a better strategy for weight management.

September 9, 2021
Researchers have shown that people with inflexible metabolisms burn less fat at night than those with flexible metabolism. The team measured the respiratory quotient throughout the night and found that despite equal ages, BMIs, and amount of fat, people with inflexible metabolisms burned more carbohydrates and less fat than did people with flexible metabolisms. The higher sleep-time quotient could be a previously unknown indicator for the risk of future metabolic disease.

How can I avoid heart disease or stroke? ... read more
August 30, 2021
As much as 90% of the risk of a heart attack, stroke, or peripheral arterial disease (PAD) can be explained by smoking, poor eating habits, lack of physical activity, abdominal obesity, high blood pressure, raised blood lipid levels, diabetes, psychosocial factors, or alcohol. These guidelines focus on atherosclerotic cardiovascular disease (CVD), which affects the arteries. As the inside of the arteries become clogged up by fatty deposits, they can no longer supply enough blood to the body. This process is the main cause of heart attacks, strokes, PAD and sudden death where arteries become completely blocked. The most important way to prevent these conditions is to adopt a healthy lifestyle throughout life, especially not smoking, and to treat risk factors.
Eating walnuts daily lowered 'bad' cholesterol and may reduce cardiovascular disease risk ... read more
August 30, 2021
Healthy older adults who ate a handful of walnuts (about ½ cup) a day for two years modestly lowered their level of low-density lipoprotein or LDL cholesterol levels. Consuming walnuts daily also reduced the number of LDL particles, a predictor of cardiovascular disease risk. The study explored the effects of a walnut-enriched diet on overall cholesterol in elderly individuals from diverse geographical locations and spanning two years.
Common pesticide may contribute to global obesity crisis ... read more
August 27, 2021
Researchers discovered that chlorpyrifos, which is banned for use on foods in Canada but widely sprayed on fruits and vegetables in many other parts of the world, slows down the burning of calories in the brown adipose tissue of mice. Reducing this burning of calories, a process known as diet-induced thermogenesis, causes the body to store these extra calories, promoting obesity. Scientists made the discovery after studying 34 commonly used pesticides and herbicides in brown fat cells and testing the effects of chlorpyrifos in mice fed high calorie diets.
