How important is exercise to losing weight?

Are you familiar with this misconception: "EXERCISE IS THE MOST IMPORTANT ASPECT OF LOSING WEIGHT. PEOPLE WHO ARE LEAN SPEND HOURS UPON HOURS IN THE GYM." I'm not sure if you believe that, but I assure you that plenty of people are brainwashed with this myth. For millions of people, when they see someone who is in great shape their immediate response is: "they must work out A LOT" or "they must spend HOURS in the gym." Don't get me wrong here, exercise is important and is something that is critical.
I will tell you that it is an absolute necessity to living life lean BUT, in comparison to a proper mindset and nutrition, it is… The least important aspect of living life lean! However, if you visit your local gym or fitness center you'll certainly see tons of people who haven't gotten the memo. I always see people who are well into their workout when I arrive at the gym and then when I leave they still have a ways to go. However despite this, year after year they remain overweight and look pretty much the EXACT same! I reveal the correct way to exercise in the book Living Life Lean, but I'll give you a big hint right now to what the magic formula is… Quality over quantity! In fact, spending too much time exercising can actually hinder your progress... But let me be also clear about something: exercise IS, without a doubt, one of the best investments of time you can ever make in your life. Period. The point you need to understand however, is that without having a firm grasp on proper mindset/beliefs and proper nutrition, you will never reap anywhere near the full value of your investment. This is exactly why it's important to be aware of this misconception...
