If you do regular housekeeping, you`re moderately active. However, it`s a good idea to start a fitness program. I suggest you start by running 20-30 minutes before breakfast and walk for 30 minutes after dinner. Also, you need to keep a track of how many calories you burn. To lose weight, you need to eat less calories – or burn more. Watch what and how much you eat too. Use a diet and fitness planner - that`s how you know how many calories you burn and how many you eat. You can find a free diet & workout planner at
