If you did not see the TV show few nights ago then read the book called. In Defense of Food.
I can not explain it as good at the TV show or the book (In Defense of Food) but EAT all the Green plants and beans you can. Eat real food, grow a garden. Do not eat any processed food. Do not eat in any fast food restaurants. Do not eat artificial sweeteners. Vegetables and grain have lots of stuff your body can not digest so that stuff just takes up space in your stomach and intestines. If 50% of what you eat can not be digested that is 50% less that can be stored as fat. The none digestible filler keeps you from getting hungry. The problem with processed food is, all the none digestible filler has been removed. Sugar and caffeine make you hungry. Artificial sweeteners confuse your body so it is all stored as fat. Stop eating butter, cheese, fried food, and high fat foods. You need to be tested to see if your intestines have good bacteria or bad bacteria. Even the meat we eat and milk we drink is bad for us because cows no longer eat green plants like grass, stock yards feed cows grain, minerals and vitamins. Cooking vegetables killed enzymes your stomach and intestines need. Eat lots of garden tomatoes. The none digestible filler can reduce our risk of colon cancer 100 times. Buy whole grain flour, make your own bread.
Grow a garden and raise your own cows, pigs and chickens. Not likely many people will do that. City code in the town we live in has made some amazing changes, now we can raise chickens, cows, pigs, eggs, in town. A year ago you would get arrested for raising farm animals in town.
A group of town people are in the process of starting a town food co-op group. We need local farmers to supply the farmers market people that want to be part of the group with food. We need farmers with Red cows like Jersey cows to bring as much milk, butter, cream, 100s of gallons to every farmers market, we need farmers to supply eggs, we need butter, pork, chickens, whole grain flour, bread and lots of home grown garden vegetables. We want to eliminate the need to buy grocery store foor for all the people that want to join the group and eat healthy food. This will only work if farmers supply food on a large scale and keep their prices low, you can no longer expect to sell home grown food 3 timers higher than the grocery store for this to work. Farmers need to take orders in advance like, 200 gallon of milk for every farmers market for 150 customers 2 times every week, 200 dozen eggs each farmers market, etc.
