Hi PuddleJumper!! Welcome to 3FC!!
I actually have a similar goal to you
I'm 19, and I weighed 143, and now I currently weigh 125. And I want to lose weight to feel and look better! I started mid July, and weight 125 currently. It's been a long journey, but worth it!
I used to have a problem with late night eating as well, I go to school from early morning until 6, and on the days I don't go to school, I have long shifts at work. What helped me was preparing meals the night before so I can enjoy healthy meals on my breaks during my day. I also found that keeping a food and exercise diary helped me tons!! Plus packing meals always reminds me not to buy food, so I save money and my health. At home I got rid of a majority of the bad foods so they would be out of sight and out of mind. I also made a set schedule of when to eat, and it has really kept me on track, it's like a mental alarm clock for when I can eat :P
My hugest concerns were and still are my thighs and arms as well!! But I have been doing cardio, and a bit of weight training. Although I myself don't really see a difference in my legs, other people do which makes me ecstatic. As for the arms, I guess it's something that will come off a bit later, they are definitely more firm than when they once were. Lunges help a lot!! and the elliptical as well, that is if you have time and the equipment, other than that walking is great. I try to get at least 20 min of exercise in each day.
And cheers to your first goal!! I always tend to make my goals smaller and more attainable... which means more celebrations on weight lost!!
ANYWAYS GOODLUCK!! AND ENJOY 3FC
