Today's round-up of fitness, nutrition and sports science research brings us a refreshing variety. Let's see what's on the menu:
Weight stigma in men associated with harmful health consequences
As many as 40% of men report experiencing weight stigma, but little is known about how this stigma affects their health. This study found that men experiencing weight stigma have more depressive symptoms, are more likely to binge eat, and have lower self-rated health.

One or the other: Why strength training might come at the expense of endurance muscles
The neurotransmitter brain-derived neurotrophic factor (BDNF) acts in the muscle, so that during strength training endurance muscle fiber number is decreased. Researchers have more closely investigated this factor, from the group of myokines, and demonstrated that it is produced by the muscle and acts on both muscles and synapses. The results also provide new insights into age-related muscle atrophy.

These gut bacteria prevent mice from becoming obese -- what could that mean for us?
A specific class of bacteria from the gut prevents mice from becoming obese, suggesting these same microbes may similarly control weight in people, a new study reports. The beneficial bacteria, called Clostridia, are part of the microbiome -- collectively trillions of bacteria and other microorganisms that inhabit the intestine.

Extra weight in 60s may be linked to brain thinning years later
Having a bigger waistline and a high body mass index (BMI) in your 60s may be linked with greater signs of brain aging years later, according to a new study. The study suggests that these factors may accelerate brain aging by at least a decade.

Mediterranean diet during pregnancy reduces gestational diabetes and weight gain
A simple Mediterranean-style diet in pregnancy does not reduce the overall risk of adverse maternal and offspring complications, but has the potential to reduce weight gain in pregnancy and the risk of gestational diabetes, according to a clinical trial.

Astronauts less likely to faint on Earth if they exercise in space; findings may help others with fainting issues
Up to two hours of endurance and resistance exercises daily during a long space flight mission, combined with IV fluid replacement after landing, helps astronauts prevent dizziness and fainting during normal activity when they return to Earth. The study findings also have implications for a variety of people with health conditions that cause them to faint when standing up, and people on bed rest for long periods.
