Losing weight is not as hard as one would think as long as you put your mind to it. I was overweight for the past 10-15 years. I'm 6'6" and Feb of 2012 I weighed 397lbs. I made the decision that I was tired of being fat and out of shape so I put my mind to losing the weight. I didn't go on a crash diet or any strenuous program like px90 or anything crazy like that. I simply changed the way I eat to a healthier way. I cut out all the chips and junk food, cut out the chocolate and baked goods, switched from white breads to whole bread, and switched from regular cheese to fat free cheese, as well as started simply walking between 3-6 miles per week.
With in less than a year I lost almost 150lbs and went from 397lb to 250lbs which is where I am at today. Just keep your mind to it and make the decision that you want to live a longer and happier life and you can do it.
