One sure way to slim down is through walking. This quick weight loss strategy has helped millions of people get rid of stubborn fat. You don’t even need to jog or speed-walk to slim down, the latest findings show going slower burns 146% more fat. The experts found that bouts of vigorous physical activity prompt the release of leptin, a hormone that stimulates appetite and slows metabolism. They say that walking more slowly is actually best for a speedy slimdown. Why? Because a slower walking pace allows cells time to convert fat into usable energy. When intensity increases, muscles turn to glucose, a faster source of fuel.
