Do a little yoga. It can double your metabolic rate first thing in the morning. I recommend a gentle cycle of two sun salutations. If you're new to yoga, check out my seven-minute morning routine (which also includes a few strength-building exercises).

Drink cold water. Five hundred milliliters of H2O (a little more than a pint) may spike metabolism by 30 percent for as long as an hour. Water triggers the sympathetic nervous system, which in turn stimulates your metabolism. On top of that, cold water may force your body to use energy to warm it.

Take 500 milligrams of white bean extract. In a 2007 study, people who took the extract (which may slow the absorption of carbs) for 30 days experienced a significant improvement in their muscle-to-fat ratio. That's good news for metabolism since muscle burns about three times more calories than fat.
As a reminder, always consult your doctor for medical advice and treatment before starting any program.
