Try running, jogging, swimming, treadmill, elliptical, skipping and you will lose
weight. You have to remember that you have to fix your input. Plan and prepare a diet
chart for around 1800 calories / day with the help of a dietician.
If you follow this plan for a period of 3-6 months rigorously you will see changes.
It is good to know that you eat healthy but still take the help of a nutritionist or a dietician.
