The U.S. health and fitness industry, which includes the weight loss industry, is worth $60 billion a year. There are infinite plans, pills and programs; many people struggle on a daily basis to regulate caloric intake and mindlessly go for anything with "Low Fat" plastered on it.
Interesting that before the Industrial Revolution, there was no such thing as 'organic.' Everything was grown in nutrient-rich soil, without pesticides, and all meat was free-range and untainted. There was also really no such thing as exercise, at least how it is now construed. People were naturally active on a daily basis.
I suppose my point isn't all that profound: just that you don't need any special regimen at all. You just need to walk and run and move more, every day. You don't need to have a dietitian or a book or a celebrity or a commercial or a product package to tell you what to eat. You just have to use some common sense (just because an avocado is filled with fat does not mean it is bad; whole unpasteurized milk is superior to skim milk laced with antibiotics) and try to listen to what your body is telling you.
If you are free from addictions to MSG, salt, sugar and other processed foods and additives, then you can follow your cravings to what your body may need. For example, if you find yourself craving sweet potatoes, you may be deficient in vitamin A. If you love clam chowder, your body might be appreciatively gobbling up all that iron and zinc. Love tomato sauce-slathered pasta and orange juice? (Yes.) You may need to stock up on Vitamin C. Even wanting to indulge in dark chocolate means that your body may require a little burst of mood-boosting serotonin.
There are endless good things to eat and drink, each filled with unique and miraculously beneficial compositions of minerals, amino acids, antioxidants and/or nutrients. And to have them all on hand 24/7 at the corner grocery store — I know I have the Industrial Revolution to thank for that.
I would just like to point out that there is no need to pay for any person, program or pill, or to even count calories. It's all about the quality of ingredients and if the food product is pure and unadulterated. If you eat only high-caliber, whole foods, and eat only when you are hungry, and follow your cravings, plus walk a lot more than you sit, then you should not have much of a problem with your weight, metabolism or health.
