Due to my extensive lifestyle change, one thing has become abundantly clear. Fine dining and elaborate meals are the root of all evil!

Eating used to be an event. And I guess it still could be if I really wanted to go to all the trouble. But this entire notion that meals are an event I think serves greatly to sabotage our health. We eat because we like to and not because we need to, and that is a big part of the problem, IMO. In the spirit of the season, consider the classic Thanksgiving meal. Jeez, I can't even imagine eating so much food any more. And the carbs, carbs, carbs, carbs, carbs... When you can't eat carbs [a bare minium] you quickly notice how many carbs most people eat. We live in an environment that is super-saturated with carbohydrates.
Eating well, I have discovered, is actually very easy, fast, and cheap. Sometimes I just eat [scarf down vegies mostly] while standing at the counter. Sometime lunch takes less than five minutes. And breakfast is just a protein drink. I still usually make something for dinner but nothing elaborate.
Now I understand why diets usually fail. There really is no such thing as an effective "diet". It has to be a lifestyle change that remains a constant. And for me that meant losing the classic breakfast, lunch, and dinner, where would I sit and eat until I'm full, and usually too full. Eating far less more often is far better. Diets don't work. Lifestyle changes do.
Just food for thought in this holiday season.
