Blood sugar control is critical as we get older, but especially for the millions of people with type 2 diabetes. Researchers in New Zealand have discovered a fairly simple way to maintain blood glucose levels after meals – what they call exercise snacks. They compared 30 minutes of continuous, moderate-intensity exercise before a meal to six one-minute intervals of vigorous intensity exercise – walking an incline – alternating with one minute of rest, performed 30 minutes before a meal. Those who performed the exercise snacks, or the six one-minute high-intensity exercise bursts, had lower blood glucose levels three hours after the meal, as well as lower average glucose levels for the next 24 hours. Finding some way to get even small amounts of physical activity before meals might go a long way to improving our health.
