If you're at risk of developing type 2 diabetes, a small new study suggests taking a 15-minute walk after every meal to curb a "risky rise" in blood sugar, although researchers say larger trials are needed to confirm results.
Blood sugar spikes after meals. In young, fit people, insulin helps drive that sugar, or glucose, into muscle cells and the liver, where it's stored for energy. But the system is less efficient as we get older, and leaving too much glucose in the blood can lead to type 2 diabetes and cardiovascular damage.
