Fats are NOT the devil & fat doesn't make you fat. Your body needs fat! Your weight loss and ultimately health will suffer if you are NOT giving your body enough fat. Good dietary fat is used to build the outer lipid layer of every cell in the body, and if that layer is impaired, your ability to process carbohydrates will be impaired, and you'll get fatter.
The reason people are putting on weight and getting sick is not because they are eating too much but because they are eating too much FAKE foods. From this experience my message to health professionals around the world is to advise your clients or patients to eat less fake food and exercise the choice to eat real food more!
0 days ago I started a 21 day experiment where I eat 5,794 calories of a low carbohydrate high fat to diet to see if a calorie is really just a calorie. I have come across some militant scientists, who say my experiment is bogus, and some very supportive ones, who have applauded me for trying to push science forward.
Now don't get me wrong, in terms of weight management having the right energy balance is important, you can have too much energy or too little energy from food. Calories can give you sort of a ball park figure, but for measuring energy in food, especially for weight loss, they aren't particularly accurate or even scientific.
