Simply put, Clean Eating is eating more of the best options and less of the bad options.
Choose whole, natural foods and seek to eliminate or minimize processed foods.
Processed foods are anything in a box, bag, can, or package, and although there are always a few exceptions to the rule (like a bag of fresh green beans), the majority of your foods should be fresh.
Choose unrefined over refined foods.
While it may not be possible all the times, you can up your intake of whole grains like brown rice, millet, amaranth, and quinoa. Beans and legumes are also important. Clean sugars include honey, maple syrup, and dehydrated sugar cane juice.
Include some protein, carbohydrate and healthy fat at every meal.
Most of us typically do well with carbohydrates and fat, but we often lack protein, especially in the early part of the day, like at breakfast and lunch. Protein is an important muscle-builder, and it can also help curb your appetite. When eaten throughout the day, it keeps us feeling full longer.
Watch out for fat, salt, and sugar.
This is easier than you think, particularly if you’ve cut out processed foods, which contain most of our excess calories and high levels of fat, sugar, and salt. Clean foods are usually naturally low in all of these ingredients.
Don’t drink your calories.
High calorie drinks like specialty coffees and soft drinks, on average, tack on an extra 400 to 500 calories a day. Choose water first, or my personal favorite, unsweetened tea (any flavor).
