Question Relating BMR and Daily Calorie Intake

JJ_is_Coolio

So I'm 19, 6ft, and 358lbs, my BMR according to the calculation is 3000 but I only get around 1400 calories a day. I'm only eating enough to be full I don't want to overeat. Is this bad and if so what should I change

As a male you should be eating at least 1500 Cal a day, so to begin with, the 1400 is an iffy target unless prescribed...

As a 19 yo male... even more so.

You are at an optimal age to develop some great muscle mass. And under the excess fat you already have some really good lean mass which will come out and will make you feel like you're flying as you start losing weight. Make use of the feeling to develop some good and consistent and frequent exercise habits.

You've obviously started at the wrong foot with over-eating these past few years--you couldn't have gotten to 358 otherwise. You do have to make some changes moving forward.

My suggestion?
Eat and move like the person you would like to be the rest of your life.
Do you see you eating the rest of your life like you're eating today?
Is your "1400" calories a sustainable, forever, way of eating?

Let's see here.
22 year old 6ft BMI 25... 190lbs.
Lightly active: 2646 calories
Active: 3024 calories

I would say that there is zero reason to assume that if you were to eat 2650 Cal a day (accurately counted) that you wouldn't lose weight on a fairly consistent basis. And I would personally probably aim for 3000 until and unless I *had* to drop below that.

And doing so might help you develop habits that would be of use to you in the future as opposed to only developing "diet" strategies.

Under eating is as bad for you as over eating.

Eat what MFP says.

The thing is, I'm not following any sort of diet or routine I'm only eating enough to keep me full. I recently came off a medicine that had a main side effect of weight gain, I had been on that for around 8 years and since coming off that I have lost 16 pounds. I haven't changed anything with my diet or exercise.

Buy yourself a food scale and start logging your food accurately- stop undernourishing yourself.

@PAV8888 gave some excellent advice, if you don't wish to follow the MFP suggestion for 2 lbs a week, follow that.

Choose food you enjoy,and plan to eat for the foreseeable future, aim to reach your nutritional goals daily, move more doing something you like, walking is fine.

Cheers, h.

I"m really struggling because I am only eating what makes me full, Thank you all for the advice. I've been at a point in my life where I would eat so much that it would hurt me and now I really don't like to eat when I am full. As of now I am 356 lbs and last month I was 374 lbs. I've always been told that losing weight fast is bad and I know that it is but its not like I'm starving myself, throughout the day I am mostly full and I eat when I get hungry.

Try adding some higher calorie foods. If you eat dairy go for full fat versions. Someone's created a list so use the search facility, or google, abd if 3000 is likely to be maintenance, when you hit goal I'd aim for that
