My weight now is 90 kg.I want to be 78 kg.How and how long?

Answer 1

find calorie/fitness calculator on the net, enter all your stats and it will tell you how many calories you need a day to maintain, take off 300-400cal off that number and thats how much you need to lose.
dont try to lose more than 1-2lbs a week - its not healthy to lose more.
eat 5-6 small meals a day (eat every 2-3 hours)
5-8 servings of fruit and veggies a day
8 glasses of water
have complex carbs for breakfast - they give you energy
have lean meat (protein) for dinner - repairs muscle
cardio exercise 4-6 times a week for 30-50min, light weight training
dont consume foods that are made of white flour (white bread, cakes, past etc.), sugar loaded foods (cookies, icecream, candy etc) and nothing fried - no junk food.

Answer 2

I tried the following activities and it took about 14 days I guess!
every day drink 8 glasses of water, dont eat junk food example chips, popcorn, candy, butter except if its low fat.,and others. everyday excersice for about 1 hour, like jog 10 min, run 10 min, push ups, 10 min, jumprope, 15 min, stretch, 5 min and run again for 10 minutes!
