I've been trying to get an answer to this question for a week, and can't seem to get a straight answer. Does anybody have a clue?

If I have 800-1000 calories a day and 60-70 grams of protein a day,

How does burning 700 calories at the Gym effect those those numbers?

Should I increase my Calorie intake so my body doesn't think I'm starving?

And go into starvation mode? At this pace I'm loosing inches but NO lbs.

I need to know what to do.....advice?

I am a biggest loser fan. They exercise a lot and when they don't get enough calories then they don't lose. I have heard Jillian say that very thing.

my understanding is that your body will go through an adjustment period, and then realize it's not startving and will stop retaining everything. Also, my doc said that losing inches is the best indicator- it means you're burning fat, not just losing water weight. Additionally, I think by definition 800-1000 cals a day IS a starvation diet no matter how you slice the pie. Of course, I think we all eat around that amount. Which takes me back to my first remark- you're body will hold on to everything until it understands it's not starving, and then lbs will start moving. This is according to my nutritionist. Hope this is some what reassuring!

I concur 100%.

Your body going into starvation mode is really only a concern if it starts to metabolize muscle instead of fat. This won't happen if you keep your Protein up and keep yourself consistent. Your body will adjust to whatever your doing, but if you have sudden changes of excessive calories, or excessive calorie defecits, this is when you create more problems then you solve.

A good rule of thumb is to eat at least half the calories you are burning a day. Frankly, that number needs to be adjusted slightly up or down depending on the person and how much excess fat they have to lose. Track your calorie in versus out carefully, keeping it as consistent as possible. Make small changes of less then 10 percent at a time, and it will never be a factor.

Use an online BMR....basal metabolism rate calculator to figure out what your burning per day. Then just add in any calories burned for exercise to get a total burned for the day. It will end up being about 800 to 1200 calories for most people to lose weight without going in to starvation mode.

Remember your BMR goes down as you get smaller, so you have to consume less calories to maintain the same rate of loss, or increase your exercise. The healthiest is to increase exercise, but I'm a realist, and except that I'm not probably going to do that, and neither are a lot of people.
