Hey babe! I put on my weight when I was 19 as well. So let me see if I can throw you some advice
First of all.. 110? That is on the very low end of the recommended height/weight chart for women. Only someone that is small framed should weigh that. A lot of people like to think they are a small frame, but it is actually not that common. Most average people are medium or large frame.
So 5'2 or 5'3 for medium frame.. you are looking at somewhere between 122-130lbs.
(You can determine frame size by measuring your elbow. Here's a
guide. And here is a good free height/weight
chart.)
Okay! So, hopefully you haven't clung to the horrible teenage habits of eating barely enough for a bird to live off of. Most dietitians are going to recommend that you eat at least 6 times a day. Breakfast-snack-lunch-snack-supper-snack.
All of these should be small. Meat should not have breading or be fried except on rare occasions. Your breads/starches should be limited as well. The diet I am on only allows for one serving of bread or starches a day.
You have to put enough fuel in your body to support your workouts.
Now, exercise should be a mix of cardio and resistance/strength training. I'd recommend pilates for you! You should warm up with about 5 minutes of running or aerobics, enough to get you going.. then do some resistance training. Your goal is to build long lean muscles because they burn calories and fat.
The biggest offensive you are going to launch will be your diet though. Workouts are less than half the battle. Diet is going to be something you need to monitor every meal, every day.
What helps me is this: Food is just like medicine. Each kind of food has a different impact on our bodies and our mood. You always closely monitor what drugs you are putting in your body and the food you eat shouldn't be treated any less importantly.
Pay attention to the labels and calories per serving. Some containers are pretty tricky and try to make it look better than what it really is.
My Pyramid is actually a pretty good site to figure out what the best kind of servings you should be eating for you.
Okay, I think I have gone on for long enough
Weight loss blogs have been my best motivation so far. Mine is
