If I replace lunch with lot of protein will I lose 7 pounds?

ok so if I replace lunch with like a high protein meal how long will it take me to loose 7 pounds

I think high protein justs makes you gain weight. Try going on a south beach diet. Their REALLY good. I dont know because im only 68 lbs. and im 15, but my mom tried it and she lost like fr*gin 70 lbs. ( she weighs 105 now. ) remember: NEVER skip meals!!! that just slows your metabolism. Don't eat much junk food, but its ok to have some once in a while. replace chips with prezels and cookies with cheese and crackers, and chocolate with some trail mix, low fat butter popcorn, and just as a random snack, eat popsicles made with real fruit juices. Their helthy and good too. one of my FAV snacks is Ants On A Log! Its REALLY good put peanut butter inside the ditch in a celery stalk, then put raisens on the peanut butter!! TA DA!!!

I KNOW THIS WAS LONG BUT IT WILL HELP!!!
