It's only quoting her. That doesn't mean the whole site is rubbish. And people do seem to burn fat faster by eating more fat and less carbs. Restricting your food intake too much slows the metabolism.
VT, you are arguing with someone who doesn't understand metabolism or how the body works, so there is no hope of convincing him, but your posts might be instructive for any lurkers that are reading the thread.
It's something that I take a lot of interest in. It used to be thought that low-fat, high carbs was the way to go. My instinct has always been that it's not true, but now the science is showing the benefit of good fats and low carbs. People don't seem to realise too that sugar is pure carb.
Without sugar we would be unable to move. You talk about carbs as if they are poison.
If you had no glucose in your blood you would simply die in seconds.
The cleanest form of energy metabolism is from carbohydrates, as the carbon is breathed out as CO2, and the the rest is water. Proteins and fact have other chemicals that have to be shifted from the blood, which are toxic.
There is nothing more faddy than diets. New diets come out several times a year, many of them rehashed old diets.
But the fact remains, all diets work in exactly the same way: that is restricting the intake of calories to lower than the number of calories burned by the body.
The article you linked is risible, as are most of the diets that recommend this that or the other.
Fat people have all the fat they need and more. If they ate less than they burned then the fat in their bodies would burn. Some diets will suit you better than others but they can ONLY work by calorie restriction. They suit people differently because of their lifestyles and current eating habits.
But the most effective diets restrict calories by increasing bulk, and rejecting high calorie and low satiating foods.
Hunger is felt in two ways.
1) Low blood sugar.
2) Empty stomach.
If you eat fat, you can keep eating it until the cows come home as it takes the body a long time to convert it to blood sugar to achieve satiation. Each gramme of fat is double that of carbs and protein. It does not take a PhD in biology to work this out.
Complex carbs such as oats, satiate more quickly and also have the benefit of gradual release through the GI tract. The fibre also helps you fill up and gets rid of your hunger.
There is no finer diet that porridge made with skimmed milk.
Protein has a role to play in satiation but fat does not. A fat person can diet for months without eating a single gramme of fat, even when their fat reserves are completely gone the body MAKES ALL THE FAT IT NEEDS from protein and carbs.
As adults we need very little protein. If we have too much the body uses it for energy and this releases Nitrogenous waste into the blood causing gout (nitric acid crystals in the joints) and putting massive pressure on the kidneys to flush the ammonia from the blood. Protein has been recommended to kill hunger but does not suit everyone.
The Hollywood Diet, otherwise known as Atkins recommends zero carbs. Steak and salad it has been called.
This works because the body is forced to metabolise protein and fat into energy. This is an inefficent and dirty process, leaving the blood full of esthers, nitrognous waste, and free radicals, all of which are toxic. For young healthy people this can work well for a short time, but is not recommended for long term, and never for people with a range of conditions from gout to circulation problems, weak heart, weak kidneys.
