Protein-rich diet may help soothe inflamed gut
Immune cells patrol the gut to ensure that harmful microbes hidden in the food we eat don't sneak into the body. Cells that are capable of triggering inflammation are balanced by cells that promote tolerance, protecting the body without damaging sensitive tissues. When the balance tilts too far toward inflammation, inflammatory bowel disease can result. Now, researchers … [Read more...]
Eating at ‘wrong time’ affects body weight, circadian rhythms
A new high-precision feeding system for lab mice reinforces the idea that the time of day food is eaten is more critical to weight loss than the amount of calories ingested. Mice on a reduced calorie plan that ate only during their normal feeding/active cycle were the only ones among five groups to lose weight, despite consuming the same amount as another group fed … [Read more...]
Muscles can ‘ask’ for the energy they need
Muscles require energy to perform all of the movements that we do in a day, and now, for the first time, researchers at the Texas A&M College of Medicine have shown how muscles "request" more energy from fat storage tissues in fruit fly models. They also discovered that this circuit is dependent on circadian rhythms, which could have implications for obesity in humans. … [Read more...]
