Another Calorie Deficit Question, very confused! :S

Hi everyone,  I've been working out 4 days a wk for 45 minutes doing circuit training.  I eat around 1600 calories/day (I'm supposed to eat 2100 but it seems like too many) anyways it says I burn 621 calories so how do I calculate this? am I eating enough/too many calories?? Please help so far today I'm at 770 calories so is that actually only like eating 150 calories (minus the 621 burned) or am I at 770, so confused please help!

just enter it in the activity section and it'll tally for you... just keep your deficit under 1000 calories per day (burn - calories).

I'm eating more calories than i ever did before and i lost 2 lbs last week!! after a 6 mth plateau!  just some pause for thought.... maybe try CC guide for 10 days and see if it makes a difference for u.... :)

Thanks! I'm not sure how to calculate my deficit thats the problem.  I take my total burned (or just what I burned working out) minus the calories I've already eaten or what I should eat for the day? thanks

TOTAL calories burn (including activity) MINUS TOTAL calories consumed

you'll see your total at end of the day... so for ENTIRE day deficit should be between 500-1000. so try to eat all day long and keep it somewhere around 500 to 750.. cause u should eat all day long and not just at night...

If you log everything (food & actiivity) you MyAccount/My home will do all the hard math for you.

make sense?

Say your daily burn is 2000 calories. If you work out (so more than is included in your activity level - sedentary, lightly active etc.), log it and it will add that to your daily burn. For example, you just did some running and burned 300 cals, then your daily burn is 2300 cals. In order to lose about a pound a week, you need a 500 cal deficit each day. If your daily burn is 2000, that means eating 1500 cals. If you burned 300 cals running, you go up to 2300, so 2300 - 500 = 1800 cals.
Like reneefitz said, never create a deficit larger than 1000 cals because your body will start to hoard every calorie it can get, impeding weight loss. You'll go very hungry and you won't see the weight shift, so it's better to eat more and feel great because of it :D

thanks kateveeoh u answered my question I posted on excerise - so I should eat my extra calorie to prevent more than 1000 calorie deficit cause of excercise! yeah go me!!!  opss sorry that was my inner fat girl be happy about the extra food! just kiddin'! lol

Haha, there's never a time when you shouldn't be happy about food :D
And something I picked up from gi-jane (she has such good advice!): if you exercise a lot, your metabolism will speed up too and you'll burn more; so when you think you're creating a 500 cal deficit, you might be creating a 600-700 cal one. That's why it's best to keep it around the 500 mark, and to make sure you eat back your exercise to prevent your body from going into starvation mode :) Too large a deficit will make your body start thinking there's a famine; what would you do if you found out you had to go without going to the supermarket for a month when you usually go once a week? You'd run to your nearest one and stock up on everything! And that's basically what your body would do with calories: hold on to them.
Good luck with the weight loss :D!
