1. Eliminate Pre-Packaged Foods
2. Increase Your Vegetable Intake
3. Go Organic, Grass-Fed, Pasture Raised & GMO-Free
4. Replace Saturated Fats with Beneficial Fats
5. Incorporate Juicing & Green Smoothies
6. Increase Your Fruit Intake
I disagree. It is not beneficial, in my opinion, because of the high glycemic index in juices. One also loses the benefits of fiber and phytochemicals in the whole fruit or vegetable. It also increases caloric intake unnecessarily. I really don't understand the juicing trend.
Fruit should ordinarily be limited to one or two servings a day.
7. Decrease Your Meat Consumption
Again, I disagree. The healthiest diet for most people is the Paleo diet, which requires ample animal protein. I find that I need to eat meat at least several times a day to feel satisfied. If one does not feel satisfied, he will consume extra calories of substitute foods, like carbs, in a futile effort to feed the real hunger, which is for meat.
8. Buy Foods With a Short Ingredient List
That necessarily follows from choosing unprocessed foods.
9. Reduce Salt & Sugar
10. Increase Your Water Consumption
11. Eliminating Bad Beverages
I lost 140 pounds between Holy Week 2013 (late March) and February 2014. I went from 330 pounds to about 190. I have maintained my weight since then. I followed an approach called intuitive eating; there is an excellent, cheap book with that title that I highly recommend. In addition that, I chose mostly whole, unprocessed foods, and I ate in the direction of Paleo without becoming a fanatic about it.
As Greg says, moderation is important. What matters most is how you eat over time, not just one meal or even one day of eating. It's best to retain some flexibility. Otherwise, strictness in this matter can backfire by causing one to think he's "blown it," which leads to binge eating or, prior to starting again, last supper eating.
Beware of developing orthorexia. (Google it.)
