This question already has an answer here:

I have a bulging belly, and some jiggly thighs, but I weigh only 112lbs and am 5'5". My BMI varies between 18.5 and 19. I'm thirteen, so I'm not sure if you can help. My thigh circumference is 52cm and my waist is 71cm. What I want is a flat stomach and thin thighs. I recently ordered a circle glide cross trainer, and I want to know how long should I do it each day to get what I want.

@LegoStormtroopr: As OP is probably still in growth stage, I'd be careful with weight loss advice. – zero-divisor Aug 4 '13 at 20:14
You need to work on building some muscle. BMI is a pretty useless figure: what is more important is your bodyfat percentage, which can be determined with some skin fold calipers (~$10 on amazon). You should be doing full-body movements like burpees to get a physique that is toned all around. Also things like air squats, jumping rope, pushups, inverted rows, step-ups, deadlifts, thrusters, and so on. Try doing them in a circuit, such as 10-15 reps of each movement back to back for 15-20 minutes. You can also add things like sprints. Try doing a 15-20 minute workout every day for a month. – Daniel Aug 4 '13 at 21:08
@zero-divisor If you check my answer in that question I linked, you'll see thats something I cover. – Lego Stormtroopr Aug 4 '13 at 21:38
@LegoStormtroopr: Sorry, should have followed the link :) Maybe it's a good idea to change the title of the question you linked to because it's actually specific to teenagers and not a general weight loss question. – zero-divisor Aug 5 '13 at 6:19
@zero-divisor Good idea, I'll take care of that soon. – Lego Stormtroopr Aug 5 '13 at 6:58

People hold body fat in different proportions throughout their body. Weight is not a gauge of your aesthetics or overall level of fitness. Some body builders at your height weigh over 200 lbs but their body fat is incredibly low so they don't look fat.

If your goal is to have a flat stomach and thin thighs, plain and simple you have to reduce your body fat percentage. You can't reduce body fat in one area and not others; the human body fat scales proportionally. This comes through consistent dieting for a long period of time and frequent exercise. The body's response to this is also different for each person. Some people can very easily loose body fat with minimal effort and some people have to work harder but it is never impossible. So in general don't get frustrated if you don't see results in three weeks. It usually takes about eight to really notice a significant difference.

In reference to how long you have to exercise, that really depends on your health level and if it is even safe for you to engage in it. If you are in relatively average shape start with 30 minutes a day. Then as it gets easier through the weeks add more time or intensity (try working out harder). Keep changing your routine every few weeks (try running outside when you get bored of the machine or doing calisthenics if you can't get to a gym); your body will become accustomed to doing this type of exercise very quickly and your results will start to lag. Most importantly, challenge yourself. Your body won't change if it doesn't have a need to; create that need through your intensity and intervals of training. The main thing is diet, however. You can work out for 10 hours a day but if you aren't eating the right foods consistently every day, week after week then you won't see any change. Good Luck, Hope that helps and feel free to ask any questions.
