what to do?!?!

taylorvonlehe

i was wondering if this happened to anyone else and whats the cause. my pants are so tight now. i wear a 27 but they were tight in the legs from building muscle so i stopped doing legs with weights for a week and they go on again but they are still really hard to button. what gives? i run 4x a week and do abs and arms. pretty healthy diet. 1200 calories. i use to be vegetarian but not anymore and i lost a ton of weight from doing that. i have eaten way more sweets than i use to. any advice on how to get my waist or hips down? i have a really flat stomach. it just feels like its expanding. i guess thats my problem
