Increase Metabolism

The best way to help you lose weight and to keep fit is to increase your metabolism.cardio exercise is the best way to increase metabolism.Aerobic exercise helps to burn fat cell. Exercise in an aerobic state that is in an oxygenated state, for thirty to sixty minutes a day is one of the best ways to increase your metabolism. The best time of the day to burn fat is first thing in the morning when the body has been at rest and will use stored fat as a source of fuel. It is also best to exercise on an empty stomach so the body looks for an alternate source of energy. Running, swimming and walking are great ways to get aerobic exercise.

• Just do it. Set a small, reasonable goal. For example, I bought an exercise bike and my first goal was to use it 20 minutes, 3 times a week. I told myself that even if I just sat on it for 20 minutes while watching tv, that I would at least be on the bike! I now work out on an elliptical trainer or walk 2 miles, 3 or 4 times a week.
• Keep a record. Plan your exercise time in advance and record your progress. It's especially motivating to note how you feel. At first, you might feel sore or tired, but in a few weeks, you will have more energy and fewer aches and pains. You'll probably sleep much better, too.
• Commit to yourself that you will exercise at your minimum goal level for 2 months, no matter what happens. If you gain weight, keep exercising. Lose your job? Exercise. Feel depressed? Exercise. Get mad at your partner? Exercise. No excuses, short of illness or tragedy. And, even then, exercise might help.
