iam 4'9 145pds and im 23yrs old

And what made you pick 1200 cals?

last fall I attended a weight class through my hospital and thats what they put me on. So thats what Ive been trying to live on. the first time I tried this diet i had lost a pd. in a week. so I thought I would try it again.

That's sad.

Sad that people who are in an obvious position of authority when it comes to nutrition hand out poor advice.

So whats your advice? I'll take any that I can get.

Is that even 1200kcal ? I wouldn't have guessed offhand it was.
A good sort of structure to follow is: Eat at maintenance and bring in excersize, once you reach a plateu, take out 250kcal, then once you hit another plateu, take out another 250kcal, it gives you good results If anyone agrees with that ?

It's not bad advice actually Pink. The idea is to eat as much as you possibly can while still invoking weight loss. This does 2 things.

1. Helps fight the feelings of deprivation b/c.... duh, you aren't depriving yourself.

2. Sets yourself up for a reasonable weigh loss. Reasonable in the sense that that you won't be losing so quickly that muscle loss and metabolic slowdown (which is inevitable) occur.

Eating enough becomes even more important when you don't have all that much fat to lose, which seems to be the case with you. When this is the case, the hormonal disruptions that many label starvation response occur much faster. Your metabolic rate becomes much more volatile. And losing weight on a long term basis becomes much more difficult.

My suggestion is to always start with a straight caloric deficit. How long have you been eating at 1200 cals? I believe you said you were 145 lbs. At 1200 cals, you are eating approximately 8 cals per pound. That is low. In EXTREME cases, I have seen people have to drop that low. I would rather see you up around 10-12. If that doesn't work, then drop down to 8-10. This would give you a little more room to "wiggle" in terms of calorie manipulation. Already at 8 per pound, you are backing yourself into a corner, since I don't recommend going much lower than that, if at all.

You just have to know that plateaus are much more probable when you don't have a lot of fat to lose, due to the things I said above. Sometimes, because of this, cyclical calorie approaches are calling for when you are cycling up and down your cal/carb intake. It might be something worth noting and looking into further if you find "straight deficit" dieting doesn't do the trick for you.

I've jsu been on 1,200calorie diet the past week.I just started. So how many calories should I be taking in?

I have another question should I be doing tae bo every day or should I walk every other day?

I'd like to see you start at 12 calories per pound. Of this, you should be getting close to 1 gram of protein per pound of bodyweight and .25 - .5 grams of fats, mostly coming from the good stuff. The rest can be comprised of more fats and of course carbs.

There is no set exercise regimen that you should be following. However, I would certainly recommend weight training. Why? As I mentioned earlier, since you aren't starting out terribly far from a goal weight, your body has the propensity to "give up" muscle mass more so than you fatter counterpart.

Starting with 3-4 sessions of "cardio" per week would be a good start.

Bread is a great food, whole bread of course, is very nutritive and healthy The main problem is what people put inside the bread.. And of course the calories of that type of bread, you can easily find whole bread with like 55kcal by slice. =)

I do plan on joining curves in a month its just getting the money right now. I would love to do weight lifting, but theres only a guys gym where I live and im really shy and don't like people looking at me. So I was going to join curves and see what it's all about.
So 12 cal per pound would be around 1,700 cal. a day correct?

Yup.

Start with 1700 per day. Track your weight and your measurements. I suggest taking measurements of at least your chest, navel, waist, arms, hips, thighs, and calves on a bi-weekly basis.

Really try and stick with the guidelines I provided above concerning protein, fats, and carbs.

And I did not know there was such a thing as a guy's gym.

Curves, blah.

Don't hate on curves -it actually does help some people -it gives them the individual attention that doesn't exist in the mass market gyms and it gives people some direction.

well where I live there is a (guy's gym) I have never seen a women in there. Im too scared to go there. Im chicken.
Thanks maleficent for sticking up for Curves. lol
