My daughter had to follow the Whole30 food plan for 30 days, per orders of her doctor. For 30 days, people who follow this plan eliminate grains, dairy, and soy, (and alcohol, although that did not apply to her since she doesn't drink) and eat proteins (beef, chicken, fish, eggs), fresh fruits and vegetables, etc. The point of the program is that your food should look like food; not put into muffins or disguised or always in a casserole or covered with sauces and cheese. The meal should be recognizable: a portion of grilled or baked chicken, with sauteed or roasted or raw vegetables, fresh fruit.
Out of support for her, we followed the plan too. Their website is great, and there are Facebook pages for people who are following it, with recipes and ideas.
I lost 10 pounds!
What I observed afterwards, after evaluating how the 30 days had gone, was really interesting. I had learned what foods I routinely chose because they were easy, or fast. I don't eat badly, and I cook from scratch (no processed foods), but if I wanted something sweet, I chose a piece of chocolate without thinking. I had forgotten how nice it is to sit and eat some fresh blueberries, or orange segments, or strawberries, in the evening, instead of a cookie or piece of chocolate. Instead of a glass of wine, I had plain sparkling water with fresh lemon juice or lime juice squeezed into it.
Now we don't follow the plan precisely, but I still stick to the good things we learned.
I liked the plan because it wasn't food that was planned out for us or shipped to us, and it was real food, not packaged, processed things. We tried new vegetables, new fruits and new salad ingredients. I feel that the problem with the diet plans that provide your food or plan it out for you, or require you to count or portion or measure precisely, is that they don't set you up for long-term success. Most of us are not going to follow those kinds of plans forever, so it's best to make some good healthy switches (fresh roasted broccoli instead of frozen stuff in a sauce, fresh fruit instead of sugary stuff in a rainbow-swirled yogurt, needing to have bread with every meal - things like that), learn to appreciate food in its real form, and learn about and carefully evaluate our own eating habits.
