It’s not a bad thing if you pick a toasted bagel for breakfast, while your partner chooses eggs. In fact, according to a new study from the University of Waterloo, that difference could help you lose some weight.
The study, which employed a mathematical model of men’s and women’s metabolisms, showed that men’s metabolisms respond better on average to a meal laden with high carbohydrates like oats and grains after fasting for several hours, while women are better served by a meal with a higher percentage of fat, such as omelettes and avocados.
“Lifestyle is a big factor in our overall health,” said Stéphanie Abo, an Applied Mathematics PhD candidate and the lead author of the study. “We live busy lives, so it’s important to understand how seemingly inconsequential decisions, such as what to have for breakfast, can affect our health and energy levels. Whether attempting to lose weight, maintain weight, or just keep up your energy, understanding your diet’s impact on your metabolism is important.”
The study builds on an existing gap in research on sex differences in how men and women process fat. “We often have less research data on women’s bodies than on men’s bodies,” said Anita Layton, a professor of Applied Mathematics and Canada 150 Research Chair in Mathematical Biology and Medicine.
“By building mathematical models based on the data we do have, we can test lots of hypotheses quickly and tweak experiments in ways that would be impractical with human subjects.”
“Since women have more body fat on average than men, you would think that they would burn less fat for energy, but they don’t,” said Layton. “The results of the model suggest that women store more fat immediately after a meal but also burn more fat during a fast.”
Going forward, the researchers hope to build more complex versions of their metabolism models and extend beyond the consideration of biological sex by incorporating an individual’s weight, age, or stage in the menstrual cycle.
The study, Modelling sex-specific whole-body metabolic responses to feeding and fasting” appears in Computers in Biology and Medicine.

SAN ANTONIO — October 7, 2024 —Southwest Research Institute’s Nathan Andrews has been named an Associate Fellow of the American Institute of Aeronautics and Astronautics (AIAA). AIAA Associate Fellows are recognized for overseeing important engineering or scientific work and outstanding contributions to their field. To receive this honor, nominees must be recommended by at least three other associate fellows, be a senior member in good standing of the AIAA and have at least 12 years of professional experience. AIAA selects only one Associate Fellow for each 150 members each ...
The invasive mosquito species, the tiger mosquito (Aedes albopictus), poses significant threats to human and animal health due to its ability to spread over large geographic areas and act as a vector for numerous pathogens. Understanding the ecological relationships this species establishes in different locations is crucial for assessing its worldwide dispersion success and its role in disease transmission. To uncover how invasiveness couples with the ability to adapt to various food sources László Zsolt Garamszegi from the ...
Researchers reporting in the Cell Press journal Current Biology on October 7 have made the surprising discovery that one species of comb jelly (Mnemiopsis leidyi) can fuse, such that two individuals readily turn into one following an injury. Afterwards, they rapidly synchronize their muscle contractions and merge digestive tracts to share food.
“Our findings suggest that ctenophores may lack a system for allorecognition, which is the ability to distinguish between self and others,” says Kei Jokura (@Ctenophore18) of the University of Exeter, UK, and National Institutes of Natural Sciences in Okazaki, ...

Global warming could increase the threat posed to whale sharks from large ships, according to a new study published in Nature Climate Change.
Researchers from the University of Southampton and Marine Biological Association (MBA) predict that increased ocean temperatures will see this already endangered species driven into new habitats crossed by busy shipping lanes.
The study predicts that the co-occurrence of whale sharks and large ships could be 15,000 times higher by the end of the century compared to the present day.

We’ve seen dramatic increases in life expectancy over the 19th and 20th centuries, thanks to healthier diets, medical advances and many other quality-of-life improvements.
But after nearly doubling over the course of the 20th century, the rate of increase has slowed considerably in the last three decades, according to a new study led by the University of Illinois Chicago.
Despite frequent breakthroughs in medicine and public health, life expectancy at birth in the world’s longest-living populations has increased only an ...
A study led by Johns Hopkins Medicine researchers concludes that commonly used ways of positioning the patient’s arm during blood pressure (BP) screenings can substantially overestimate test results and may lead to a misdiagnosis of hypertension.
In a report on the study, which will be published Oct. 7 in JAMA Internal Medicine, investigators examined the effects of three different arm positions: an arm supported on a desk, arm supported on a lap, and an unsupported arm hanging at the patient’s side. ...
About The Study: This crossover randomized clinical trial showed that commonly used arm positions (lap or side) resulted in substantial overestimation of blood pressure readings and may lead to misdiagnosis and overestimation of hypertension.

About The Study: The transition from childhood to adolescence may represent a sensitive developmental period when racism can have long-term deleterious impacts on healthy human development across the life span. Future research should build on the present study and interrogate which social regularities and policies may be perpetuating discrimination against ethnically and racially minoritized adolescents.

A blood test, performed when metastatic prostate cancer is first diagnosed, can predict which patients are likely to respond to treatment and survive the longest. It can help providers decide which patients should receive standard treatment versus who might stand to benefit from riskier, more aggressive new drug trials. The research, part of a phase 3 clinical trial funded in part by the National Cancer Institute (NCI) of the National Institutes of Health, was just published in JAMA Network Open.
Before it spreads, prostate cancer can be cured with surgery or ...
October 7, 2024—(BRONX, NY)—Metastatic disease—when cancer spreads from the primary tumor to other parts of the body—is the cause of most cancer deaths. While researchers understand how cancer cells escape the primary site to seed new tumors, it’s not well understood why some of these wayward cancer cells spawn new tumors— sometimes decades later—while others do not.
Now, a research team at the National Cancer Institute-designated Montefiore Einstein ...
