Simple gradual changes in one' s lifestyle affect the weight and how we feel overall over time.  

Excessive weight comes from the imbalance between the energy that we put into our bodies by consuming too much or the wrong kind of foods and the amount of energy that we use (exercise).

Here are some simple steps to take to improve your lifestyle and thus your weight:

1. Eat breakfast, lunch, and dinner
2. Snack between meals
3. Every time you eat, have a fruit or vegetable
4. Don't drink pop (maybe once a month for a special occasion!)
5. Cut down on juice (it's full of empty calories)
6. Reduce fast food intake to once a month for a special occasion
7. Drink plenty of water
8. Exercise daily for at least one hour (walk, swim, ride a bike, jump the rope, etc.)

Try doing Yoga in the morning or go for a jog in a park nearby. Eating less would not help losing weight sometimes, but try a dash diet. Check with your doctor for more advise.
