Please Help Me -- Unsure about something

To keep your weight loss at 1 lb/week you would eat the 1700 + 150 (1850) as eating 1700 and not exercising is the same as eating 1850 and burning 150 they both net 1700.

Very commonly asked question this...

Simple answer is this: weight loss comes from calories in minus calories out. So, if you are targeting a 1lb a week loss, that means that you want your calories used to be 500 more per day than your calories consumed.

if you do exercise, you are increasing your calories used. If you eat them back you will still loose 1lb a week.

You can choose to eat back less than you use and loose weight faster - but be careful not to under eat as you will feel tired and grouchy and will probably not do any exercise the next day.... As a man I recommend that you try not to net less than 1400 calories (i.e no more than 200 calories left over on any day) - and you don't do that all the time - I lost weight quicker netting 1600 calories than 1400!

Note that getting fit is a separate but equally important goal to loosing weight - if you are fit and do regular exercise you will feel better in yourself (releases endorphins) and you will find it much easier to maintain your weight when you have finished dieting. Plus its fun

WoW! So what happens if say I have a a 1400 calorie diet....I ended up just eating like 700 calories then I worked out and burned 900 but went home and ate..After all said and done according to calculations I had 1,195 calories remaining....Am I working against myself if I don't eat them?

Yes!

I mean, if you do it on one day as an exception then it wouldn't matter - but do this regularly and you will make yourself ill!

My only caveat would be that most gym machine calorie counters and tables of calories burned by exercise tend to over estimate how many calories you are actually burning. Do you ever wear a heart rate monitor? I think wearing it can give you a little more insight as to how much you are actually burning.
