The problem is that most people don't know what "eating well" and "exercising" really means. I will take myself as an example. When I graduated from grad. school in December of 2011, I was 270 lbs which at 5'10" is fucking fat. I had some idea that I needed to eat less. I remember going to a nutritionist and a doctor back in school. She gave me some vague ideas that were taken from the pyramid scale about how I should be having 3 full meals a day and should incorporate "some exercise" every day. It took me two years to understand that no diet actually works as well as a life style change. It took me that long to understand everything from macros, to body fat percentage and to be able to accurately predict my weekly weight based on my intake. This was all stuff that I had to learn on my own. For example, common wisdom is to exercise more, jog say 30 minutes a week. Last week, I ran 4.5 miles at 8 minutes a mile. My heart rate monitor told me I burnt 200 calories. That is one tablespoon of peanut butter. There are loads of people who spend 3 hours in the gym and then go "re-energize" with a frappucino which completely destroys the time in the gym. This shit is not easy to understand and comprehend. However, yes it is doable. I lost about 110 lbs over the past two years and have consistently kept it off but I know this will be a struggle forever to reshape myself. However, when I look back into notes I made, I realize how hard the process really is.
