I agree 100% with everyone else who said you need more protein. It keeps you satisfied WAY longer than carbs or fats (I think the latest statistic I read said for 3 hours or so, but someone please correct me if that's wrong).
Also -- and I think most importantly -- protein is what feeds your muscles, and one "risk" everyone runs while on a weight loss plan is the possibility of losing muscle mass. Which is bad for several reasons:
1. Every pound of muscle you have burns something like 50 calories a day just by EXISTING, whereas fat just sort of sits around and "does nothing" in comparison. So for every pound of muscle you lose, there are 350 calories a week that you don't burn anymore. And unless my math is completely wrong (which is possible), that can result in a 5-pound gain in one year (it takes an extra 3500 calories to gain a pound). This is why most people tend to gain 5 - 10 pounds a year once they hit late middle-age: the older we get, the more muscle we lose.
2. Now lets say a person DOES lose lots of muscle on a weight-loss plan. If that person runs into trouble with their plan and regains the weight, only the FAT will come back...not the muscle. Example: If a person started at 189 lbs, lost 50 lbs without feeding or working her muscles, and then regained back to 189 lbs, she would actually be a "fatter" 189 lbs because fat takes up a lot more space than muscle. I stole this pic from another post (I hope that's okay?!):
3. Picture in your head a celebrity you want to look like. Is she just "thin?" Or does she have defined shoulders, tight calves, and fantastic abs? If she has a "nice bod" versus just being "thin," it's the MUSCLE that gives her that look. You could be "thin" and look like Olive Oyl, or you could be "fit" and look like Jennifer Lopez.
4. In addition to getting your protein, I also -- obviously -- highly recommend weight training. I won't get into it too much here as there is an entire forum on it, but let me tell you a quick story. Back in 1995, I lost about 20 lbs, which brought me to 150 lbs -- which is basically where I am now (again). But back then, I got to 150 lbs by cutting back pretty harshly on calories and doing only cardio -- I paid no attention whatsoever to protein intake or working my muscles through weight training. HERE'S THE KICKER: When I was 150 lbs in 1995, I was a size 12. Today, at 149 lbs, I'm a SIZE 8. And...ah...the last time I checked ONE POUND does not equal 2 dress sizes!!! It's because this time, I BUILT muscle, so I'm a
fit 150 -- whereas in 1995 I had LOST muscle and was a
flabby (and therefore bigger) 150.
So my point is that your goal (and my goal) should be to lose FAT, not muscle! And you need protein to do that.
Phew. {{{wipes brow, stretches fingers, and reaches for protein shake}}}
Okay, done

. Sorry I got kind of carried away and slightly off-topic, but I'm (OBVIOUSLY) a big fan of protein

.
BY THE WAY (not done, I guess

) congratulations on just STARTING!!!! That is a
huge thing!!! And everyone goes through ups and downs -- especially (IMO) at the start. I mean you didn't just wake up one morning knowing how to drive a car, right? No, you had to stall out in traffic, smash into a few curbs, and hit the brake instead of the gas a few times before you "got it," right? You'll hear/see alot of people around 3FC call it "a journey"...because there's a lot of new and interesting things to learn about nutrition, exercise, and (most importantly) yourself. And the odds are that when you made the (hypothetical) mistake of hitting the brake instead of the gas when you were learning to drive, you learned not to do it again (hopefully

). Same thing with weight loss. Make a mistake, learn from it, and move on
