“Yo-yo” dieting isn’t just a problem for your clothing budget as you try to keep up with your fluctuating jean size. It’s also bad for your bones. As unwanted pounds melt away, a dieter’s skeleton typically loses mass and strength. When the pounds come back, the lost bone doesn’t.
Diet and the Microbiome
The gut microbiome — a teeming mass of bacteria, fungi, viruses, archaea and protozoans that live in our lower gastrointestinal tracts — has captured the attention of health-conscious consumers. Through controlled studies with mice, scientists have learned that by manipulating the microbiome, we can induce weight loss, affect pain perception and decrease hormonal responses to stress, among other fascinating outcomes. We know that the microbiome interacts with the immune, neuroendocrine and cardiovascular systems to affect health.
