Hi Niharika ,
yes some amount of fat is essential for us. if you are looking for weightloss, stcik to less than 5 tsp of fat a day . but a 2000 calorie chhart is too much for weight loss. if your purpose is any other, than upto 7stp fat is allowed in a 2000 calorie diet chart. dont forget the sources of these kind of fat is also imp. so avoid saturated fat , stick to mono unsaturated fat like olive oil, mustard seed oils and peanut oil ... avoid hydrogenated fat completely
