| I assume you want to lose fat. If this is the case, which likely it is, KNOW RIGHT NOW that it takes TIME. You're DREAMING if you think you can loose everything in a few short months. This takes almost 1 full year of ACTUALLY STICKING TO IT to get what you want.
Anyways, I recommend that you keep on skateboarding. You enjoy it, and you burn calories, VERY good. I would also recommend weight training, and even cardio for fat loss.
Stay away from saturated fats, and sweets. Eat lotsa fruits, vegetables, ect. Sweets sure are tempting, but sweets are not as SWEET as your results that you could get without them. |
