There are many people who eat low-carb and there are many people who eat natural foods but not that many who put these together, although the number is growing daily, very much to the dismay of giant food processing companies.
Most people realize at this point that most of the inside aisles of a grocery store should be avoided as they contain mostly processed food (apart from toilet paper and toothpaste).
But on the outside of the store there is much wrong as well.
Unlike the preaching that we have heard for the last 30-40 years from various health organizations and governmental agencies low-fat and fat-free foods are, apart from fruit and vegetables, not natural foods.
God, in his wisdom, put protein and lots of fat in milk, eggs, meat and fish as well as in nuts and some fruit (olives, avocados). If we take this fat out we are not only changing macronutrient ratios but also affecting the availability of fat-soluble vitamins.
Fat in the form it occurs in natural foods is not harmful to our health but a great source of energy for our body IF OUR BODY IS USED TO USING IT.
If our body is getting mostly carbohydrate offers (including grains, sugars, legumes) it will be good at burning sugars, and the calories our body can store in that form are very limited to a few thousand calories. This makes us very dependent on frequent meals before and after exercise and sometimes during.
The more we shift our body from eating high-carb and low-fat to low-carb and high-fat the better our body becomes at using fat as fuel. The real gain for people who want to lose weight is that once our bodies become efficient fat-burning machines (nutritional ketosis) they don't distinguish between fat in the diet and fat stored in our fat deposits.
Being able to use fat (in the form of ketones) for energy allows ideal brain function and exercising without having to eat before and after, it makes snacking unnecessary and it keeps hunger away because the body always has a great fuel source of at least 40,000 calories (for a normal weight person, more if you are overweight).
Once we can shift our body to fat-burning (it's own) the only food that we need to add is enough protein to sustain us and grow muscle and enough fat as well as micronutrients like vitamins and minerals.
The other benefit of a high-fat/low-carb natural foods diet is that none of these foods are addictive like grains and sugar are for so many of us. Eating becomes a pleasant and pleasurable experience again without the temptation of binging eating, constant obsessions about food and other consequences of calorie-restriction that so often lead to eating disorders and gaining/losing cycles.
Low-carb and ketogenic diets are at this point considered to prevent, cure or improve many diseases including, heart disease, Alzheimer's, many auto-immune diseases like MS, rheumatoid arthritis, cancer, neurological disorders, hormone disorders, dental health, diabetes and fatty liver.
They are safe to use for the rest of your life as a life-style diet.
For most people even emotional eating now becomes much easier to manage as the physical cravings are mostly gone.
