How can i loose weight in a short time?

No such thing: There is no such way to do so in a safe way. There is no magic trick. If there was, everyone on earth would be doing it. Do it the way you know it has to be done - through consistency, moderation, and healthy practices (food choice, portion-control, and exercise).

Diet and exercise: One ofthe keys to losing weight and keeping it off is to do it in a thoughtful and meaningful way. This includes having the right perspective on food, exercise, sleep, and stress. For food, eat mostly a plant based diet with lots of vegetables, fruits, nuts, beans, seeds, and whole graims and for protein eat wild fish like salmon every other day. Avoid processed foods. Exercise up to 45 minutes.
