How can lose weight ?

You will find a lot of suggestions on net but the important thing is how dedicated you are toward your goal.
Don't try to loose weight too abruptly. Control your diet. Reduce carb/fat intake, increase protein. Don't eat heavy dinners and avoid food 2-3 hours before going to bed. Do regular aerobic work-outs; running, walking, cycling, swimming etc.

Hi
Thank u sumeet,
Include bottle gourd juice with mint leaves & pepper (do not filter)-Bottle gourd is rich in fiber and water and hence helps to curb hunger pangs. Drink at early morning.
Eat 5 small meals-include 2 healthy snacks.
Eat fruits & vegetable salads .
Drink water 2-3 liters daily.
make a habit of drinking warm water after every meal.
Lemon with warm water(without sweet).
Normal exercise for 45 mins(at-least for 6 days a week).

The best way to lose weight is exercise. even the 5 minutes of exercise is enough for losing the weight.
