Under calorie goal.. Problem?

but what if im not hungry? I would still have to force myself to stuff in

There are plenty of ways to add healthy calories, and yes you should be meeting your calorie goal, not eating under it, especially with such a low goal of 1200/day.

Easy way to add calories without "stuffing yourself":

Cook in healthy oils (olive oil, walnut oil) when you cook and ditch the cooking sprays. One tablespoon = 120 calories

One serving of almonds = 170 calories

Two tablespoons of natural peanut butter = 200 calories

As another poster pointed out if you can't reach your calorie goals change up what you are eating so you are consuming more calories daily. It's not healthy to constantly be under your calorie goal (most people also suggest eating at least your BMR). Eating too little will slow down your body... sure you will lose weight but it will most likely come from muscle and not fat.

Add healthy oils, nuts, peanut butter, etc. If you are eating low fat/low cal or fat free versions of foods switch those out. Have full fat/calorie yogurt, milk, salad dressings etc. It's easy to add calories without adding a lot more food.

Are you measuring your food? Measuring cups/spoons and a kitchen scale? If not you may not be hungry because you are eating more than you think you are.

if im under my minimum cal goal and not hungry so is it a good thing? Or i should atleast eat my minimum cal intake (1200) even if im not hungry coz otherwise the metabolisim slow down or something.. Is that true?

and what if i do this everyday.. ?

Several people have given you excellent answers. I will preface my anwswer with "I am not a nutritionist nor do I pretend to impersonate one". That said, I reached my goal just fine eating under my calorie counts for many days on end. However, as an educated poster said, I did also lose lean body mass as well along the road. I started exercising gradually and slowly increased my level. I added resistance training and then actually tried to put back some weight after I met my goal. (actually I passed my goal by 5 lbs). I'm now in the process of readjusting my goal by how I look. I happen to be 8 lbs heavier than at my lowest (which was too low).

Everyone I see now says "we were worried about you...you got too skinny"...but they all agree I look "FIT" now. Being a skinny coach potato is actually a higher health risk (from Metabolic syndrome standpoint) than is being obese and fit. So keep in mind, that you can reach your goal doing what you are doing. You can maintain it.....I've been where I want to be for 6 months now and have no desire to gobble up all calories in site. It's always a work in progress and your RMR or BMR (resting or basal metabolic rate - calories you burn doing nothing) unfortunately is lower than it should be as you lose and after. Research shows this..and it's why many people gain weight back. You have to eat below your total calories (BMR + Exercise) by formula if you want to maintain. You'll find this out. That's unless you have your rate measured (metabolic cart) and you closely and accurately monitor your food and exercise (hard to do).

Aerobic exercise and resistance traing are both good. Mix it up. You don't have to do too much. 30 min a day has been shown to significantly reduce insulin resistance and improve insulin sensitivity...a good thing. Resistance train will help you maintain lean body muscle mass and as alluded to by another poster....that is very important in your health and that's a fact. Research clearly shows this.

Good luck to you. Enjoy. Do what is comfortable to you and adjust it as you go. Keep getting advice, asking questions, and researching the answers. It's how you learn, change your lifestyle, and it will open your eyes to the future and you will be one of the many success stories on here! Keep it up!
