Losing weight is not a "too" difficult thing, if one regularly follows a routine, a proper diet chart; and does exercise. If you think that you need to lose weight, first, you have to change your food habits. For that, it is better to consult a dietician, who can provide you a proper diet chart, which you should follow every day. Try to eat healthy food, such as green vegetables, fresh fruits, fruit juices, cereals, oats, skimmed milk, etc. Avoid sugar, oily and spicy foods, junk food, and other high-calorie diets, as these give rise to obesity, and are not good for health.
