Like basically everyone else in the world, I've gone back and forth between diets for quite some time. Regardless of what "diet" I'm on, however, I never try to deprive myself of too much. Back in the day (when I was young, I'm not a kid anymore, but some days I sit and wish I was a kid again), when I was training for my half-marathon, I was able to restrict myself much more. Then, I was eating around 1500 calories while working out for at least an hour 5-6 days a week. Nowadays, that just isn't happening.
