Sparkpeople/calorie trackers

[katie78 0]

So I've had some weight gain and struggles, so I've been playing around with a few sites like sparkpeople. I need to lose about 15 lbs by March 20th I"m in my bros wedding and my dress is too tight!

For the amount im working out now, SP says I should be eating about 1300-1600cal a day. But my trainer says 1200-1300. I've had a complete unfill bc of constantly pbing. I plan to have some put back in soon. it's only been 2 weeks. I know it's all about calories in and calories out. I wasn't losing crap bc I couldn't get in solid Protein, and I WAS making poorer food choices bc of this problem. Everything I ate, my body hung on to.

SO who's right SP, or my trainer? Since I REALLY gotta get some weight off quick bc of my bros wedding, I thought about doing the 17day diet? Any thoughts?
