Losing weight is definitely a long and hard journey. Starting is hard, but then you discover what works, and what doesn't work. You get into the fitness kick, and it's like nothing in the world can bring shade on your fit parade.
But then you hit something harder than a wall, and wonder:
Why didn't anyone tell me these things?
1) It Gets Harder, Not Easier
At the beginning, you'll see the weight drop quickly. However, once you start to get into the rhythm of things, dropping weight will start to become much harder. As your body adjusts to the activity level, and your new lifestyle -- you've gotta push harder. You've gotta switch it up.
2) There Really Isn't An End Goal
It's more like several goals that reach you to a much bigger goal. When you reach your ~perfect~ weight, you find that there's always room to improve. A change in aesthetics may have been the initial goal, but then you realize -- I want to climb that mountain, bike those rough trails, go faster than yesterday, run 2 miles instead of 1, increase the weight on the barbell.
3) You Might Gain Your Weight Back
After losing weight, you might just gain the weight back. And this is especially true if you had drastically cut calories, and lost the weight quickly. It's a hard, long journey. The best way to lose weight is steadily. Work hard, but fuel yourself. The best way to figure out what you should eat to fuel your new, active lifestyle, is to visit a dietician. It's not always, "less is best." Dieting and losing weight is much more complicated than that.
