Can certain foods make you gain weight?

It sounds to me with all that exercise, which is a good thing, you may be substituting muscle for fat which weighs more. Try measuring yourself or just paying attention to how your clothes fit.

I've been on mfp everyday ,writing everything down, exercising 3 days a week if not 4 for an hour each time and i havn't really lost any weight.I had pizza last night for dinner (we do every couple of weeks ) but stayed at my calories and gained 2 lbs this morning! I was sooo hungry last night I thought it would be ok to eat it since I worked out,should I just not eat those foods anymore?It feels like I do this all for nothing!I don't want to quit but 2 months ,really!

You're probably just bloated. Depending on how the pizza was made, it may have had a lot of sodium in it. Drink plenty of water and weigh yourself again in a few days.

You did not gain muscle after dieting and exercising for 3 weeks. It's next to impossible to gain muscle while eating at a calorie deficit. And muscle does not weigh more than fat - it's just more dense.

This. It's water retention.

Salty food can bloat you quick.
Eating pizza one night and weighing yourself the next morning sounds like water weight.

I bet if you avoid salty food today and drink plenty of water your weight will change again in the morning.

to me, if i eat carbs, even though i stay under my cals, i will not lose weight. at all. no matter what i do.

cut out carbs and viola. weight loss!

I kind of feel the same =/ My diet is better than it was six months ago, my portions o\are smaller and overall more healthier. Fast food is limited to very very rare, when in the past it was 2-3x per week. But now I exercise an average of 5x per week, 60 min each time, and the weight is steady. Once I cut the carbs down, the weight goes... I just get so sick of the same foods!

Nice profile pic! I live about 30 minutes from there!!

I join MFP in May and I've put on 7 pounds since I joined. I have a wedding to go to in August and if I put on any more weight I'm going to be totally bummed, but I don't know what I'm doing wrong, I work out twice a week and go for walk almost every morning, and I eat pretty clean too......SUCKS

Have you figured out your BMR and TDEE?

Pizza cheese is salty and it could just be that. Don't fret just keep at it. Losing weight is not as easy as gaining it and it is a process and a lesson in patience!

Wow I am in the EXACT same boat. I gained some weight after studying abroad in Italy and was probably between 152 and 155. Last summer I was down to 141 with mfp. I'm also 5'3 and after 6 weeks of a strict 1200 calorie diet and working out 4-5 times a day I STILL cannot break 150! It's so frustrating I know how you feel. I definitely look more "fit" than I was before, but you're right, we just shouldn't weigh this much!! You're probably like me and have a somewhat athletic build, and I'm fairly certain that after making these lifestyle modifications, we've gained muscle that's tipping the scale in the opposite direction. My clothes also seem to fit a teensy bit better, but not really. We just need to keep at it and try not to splurge to often! Stay hydrated so you body flushes out the water instead of retains it and helps to keep you full. good luck
