Exercise therapy has a small beneficial effect on chronic low back pain but no impact on shorter-term pain, according to two new studies. A plant-based low-fat diet is also better at lowering LDL cholesterol levels than a similar diet without veggies.
A study of nearly 4,500 men and women found that full-time workers who spent more time on sedentary activities engaged in significantly less exercise than part-time workers. This is likely due to the limited free time available to full-time workers, leading to a greater reliance on leisure activities.

The American College of Physicians (ACP) recommends a multi-faceted approach to treating obesity, including lifestyle changes, weight-loss drugs, and bariatric surgery. ACP identifies six valid weight-loss drugs, but emphasizes the need for frank discussions about potential side effects and lack of long-term efficacy data.
Black South African children show lower physical activity levels and calcium intakes compared to white children, yet have higher bone mass at hip. This paradox suggests that osteoporosis development may start in childhood, highlighting the importance of early intervention.
