When people think of losing weight, they think about changing their eating habits and not always about increasing their physical activity. Why is just focusing on eating habits a bad idea, and how can people easily start including more physical activity in their lives?
There have been many studies where they took three groups of people: A diet only group, diet and exercise group, and an exercise only group. The exercise groups always came out ahead in the long run (about one year). The diet group sometimes is ahead in the first few months but they gain it back after that.
The fact is, if you just plan on losing fat without exercise you're wasting your time. You would be better off focusing on exercise and not worry about your diet because 9 out of 10 times once you start exercising regularly your diet will naturally improve.
There are many reasons for this, but the best way to explain it is our bodies our meant to be active and to survive. When you exercise your body is forced to maintain or increase your muscle and still burn fat for energy. If you just cut calories your body burn fats for energy, and burns muscle to survive. This occurs because muscle burns more calories so the less you have the longer you can go without food. And that's why you must be active!
Here's a fun quote from the hilarious Mel Brooks I found, concerning activity and life:
"If you're alive you got to flap your arms and legs, you got to jump around a lot, you got to make a lot of noise, because life is the very opposite of death. And therefore, as I see it, if you're quiet, you're not living. You've got to be noisy, or at least your thoughts should be noisy and colorful, and lively."
