Exercise in early life counteracts some of the damaging programming effects of a high-fat diet, a new Auckland study shows. The researchers, from the Liggins Institute at the University of Auckland, found that bone retains a “memory” of exercise’s effects long after the exercise is ceased, and this bone memory continues to change the way bodies metabolise a high-fat diet. The research team compared the bone health and metabolism of rats across different diet and exercise conditions, zeroing in on messenger molecules that signal the activity of genes in bone marrow. Rats were either given a high-fat diet and a wheel for extra exercise in their cage, a high-fat diet but no wheel, or a regular diet and no wheel.(more)
