What is the best way n a quick way to lose weight ?

Eat fewer calories: Helpful weight loss diets have natural foods that take time to chew but contain few calories. Examples include carrots, celery, and iceberg lettuce (little/no salad dressing). When shopping for fruits, buy small ones no bigger than a tennis ball, because fruits have sugar. Drinks without calories include water and green tea. A calorie is a calorie, but surely avoid sugar & simple starch calories.

Healthy lifestyle: Increase activity level...Brisk walking 4 days a week, 30 minutes a day. Watch total caloric intake. Assume 3500 calories per pound. Assume 1800-2200 calories allowance for a day. Write down everything you eat and drink and its calories.
