Day 5: Drink 3 Iced Drinks a Day: Iced Coffee, Green Tea or Water
Coffee and green tea contain caffeine, a substance that naturally steps up metabolism. Add ice and you’ll boost it even more. Iced drinks force your body to work to warm up, which burns more energy.
Day 6: Take Zinc
Zinc reduces hunger by increasing your level of leptin, a key hormone that alerts the body when you’re full so you won’t keep eating when you’re no longer hungry. You can buy zinc in 15mg packets or simply get it from your multivitamin, which usually contains about 12mg of this essential mineral.
Day 7: Exercise in Short Bursts
When you exercise in short bursts, you wake up your muscles, causing them to immediately demand more calories and then burn them fast. A short dance or walking up a sudden hill are examples of such sudden bursts that can give your metabolism a boost.
Do-It-Anytime Metabolism-boosting Exercise:
Start by sitting in a chair. Stand up but don’t use your arms. Instead use your quads and your glutes to get up. Repeat a few times for a burst that’ll build muscle and burn fat.
