How much should I eat after sleeping in?

Hey, everyone! I'm 18, on summer break, and lately I've been sleeping in REALLY late. Like, for the past week I've been getting up between 11 am and noon. So, I'm wondering, should I still eat a net amount of 1500 calories a day if I sleep through breakfast?

When are you going to bed?

LOL! Bloody lazy teenagers :laugh:

Thing is though, your body does still use energy when you are sleeping. All your basic metabolic functions are still going, you toss and turn etc.

Your BMR, or basal metabolic rate, is how many calories you'd burn if you were in a coma. Your TDEE is how many calories you burn when you add moving and waking and getting out of bed to that. Depending on your normal daily activity level, your TDEE is going to be above your BMR, but not by thousands of calories. Things that change your activity level throughout the day will affect your TDEE. By staying in bed an extra few hours, you may depress your TDEE by a (wild *kitten* guess here) 100 or so, but not by a highly significant amount.

But I'm guessing that since you are at home for the break, your entire schedule has changed (not going to classes etc), which is also going to have an impact on your TDEE. Your Mum is going to be buying you treats, which is going to up your calorie intake. etc etc...

Bottom line: If the 1500 you mention is still putting you in a deficit then you will still lose.
