Fitness/Diet Tips

I need help, encouragement, advice, etc...I am 20, weigh around 130lbs and about 5'3

I've been working hard at a program I found on simplyshredded.com. I am in my 3rd week of the program. On Mondays, Tuesdays, Thursdays, and Fridays, I do 30 min of HIIT on an eliptical as soon as I wake up. I do 4 min of moderate intensity then all out sprint for a minute and repeat for the half hour. Later on those days, I do weight training that usually lasts around an hour. On Wednesdays and Saturdays, I do light cardio: 20 min on a stationary bike, 20 min on the elliptical, and 20 min on the treadmill.

I'm usually eating around 1300 calories a day. Nothing I eat is "terrible for me." Very restrictive on processed foods. No hydrogenated ingredients or unnecessary sugars. I eat 5 small meals a day, every 2-3 hours.

Problem is...I've gained weight! Nothing fits looser, in other words not seeing much of a difference in my overall physique.
