Should I see a doctor?

I decided to start counting calories. I've been counting very carefully and as accurately as I could. I started about a week ago, just counting everything I eat without changing anything. Apparently my daily intake lands between 3300 and 3600 cal per day. A lot of people say they eat only 2000-2300 a day, sometimes less. My weight fluctuates around 165lbs, and I'm just over six foot tall. I tried only eating a 'normal' amount but I was weak, lightheaded, and irritable the whole day and couldn't get anything done and had a major brain fog. Could it be a thyroid problem or just a fast metabolism?

A lot of people say thats a very high amount but to me that's normal and if I ate less then that I couldn't function. I run 2-3 times a week hard, ride my bike almost every day to and from work unless I take the bus, that's a eight miles round trip, and I go on hikes multiple times a week and occasionally lift, if that helps.

You are perfectly healthy at your height and present weight. you stick to your diet that you were on, as you had no problem before you changed .

Congratulations on your ability to count calories. Don't be too quick in assuming you have a medical condition because you burn a lot of calories. Metabolism is a very complex topic that ought not be simplified to calories in minus calories out equivalent to weight gain or loss. The human body is adept at handling food shortages, but is not so adaptable to our current conditions of food excesses currently experienced by most Westerners. The quality of food consumed is important. If you maintain a good balance of foods with adequate fiber, minerals, carbohydrates, protein, vitamins, and other nutrients, you do not need to count calories. Your inborn appetite regulatory system will tell you when to eat and how much to eat. For more information, see the excellent web site of Michael Greger.
