Are you inappropriately hungry?
If you feel hungry, even though you have had plenty to eat, it is probably because your body is starving - for the nutrients that you get from real foods. If you eat processed foods (foods that come in boxes, packets, cans, jars and that you buy in supermarkets, fast food outlets, or take-aways) you might be amazed if you get to taste fresh organic produce. And how satisfying real food really is.
Discover the difference by sampling organic bananas, tomatoes, carrots, greens and whatever you can find. Source milk from grass-fed cows, buying full-fat unhomogenised milk, raw if you can get it. Seek out meat that has been raised on grass on an open pasture. Rid your kitchen of everything that comes from a factory - products such as potato chips, any breads that are not sourdough, cookies, store-bought cakes, supermarket pies, sweet things, margarine, and low-fat foods, all of which contain the manufacturer's secret addictive ingredients and are missing the natural fats and other micro-nutrients you need to digest them properly.
When you eat high-nutrient, natural-fat foods, your body is able to digest them properly, and you get several times as much of many important nutrients
Stay with it. Its a lifelong change. You'll eat less, lose or gain weight back to normal, your skin will clear, and you'll feel so much better.
