I literally trust nothing I read so I researched what you were saying to understand the science behind the second paragraph for about an hour.

After eating, blood glucose levels rise, which triggers the pancreas to release insulin into the blood. Insulin is the signal for the body to absorb glucose from the blood. Most cells just use the glucose to supply them with energy. The liver has a special job when it comes to glucose. When levels of glucose (and consequently insulin) are high in the blood, the liver responds to the insulin by absorbing glucose. It packages the sugar into bundles called glycogen. These glucose granules fill up liver cells, so the liver is like a warehouse for excess glucose. Processing the body's fat is a key job for the liver. Once the liver is full of glycogen, it starts turning the glucose it absorbs from the blood into fatty acids, for long-term storage as body fat. The fatty acids and cholesterol are gathered as fatty packages and delivered around the body via the blood. Much of the fat ends up stored in fat tissues.

More concisely:

1. You eat.

2. The body breaks down carbohydrates into glucose.

3. The pancreas monitors levels of glucose, releasing insulin when the levels reach a certain point.

4. The insulin signals the liver to begin collecting glucose (this does not happen in people with diabetes which is why they have high blood sugar. Super interesting point).

5. Glucose is then stored as glycogen.

6. When the liver gets full of glycogen, glucose is turned into fatty acids and cholesterol.

7. These fats are distributed for storage in the rest of the body.

Even if everything so far is true, what you end up with is a calorie deficit, and those calories that were stored as glycogen and fat now have to be burned or you would die of actual starvation. Because those calories were inefficiently turned into fat, and now also have to be turned into glucose, you would end up burning more calories than if your body would have turned them into glucose and glycogen in the first place due to the breakdown process.

My point is, that weight loss will occur no matter what you eat if you don't eat more calories than you burn. If the idea here is that by avoiding eating carbs you don't signal your body to produce fat cells that's ignoring that your body directly converts lots of things into fats.

Actual fats, for example, are transformed into body fat (fatty acids) like this:

1. Large fat droplets get mixed with bile salts from the gall bladder in a process called emulsification. The mixture breaks up the large droplets into several smaller droplets called micelles, increasing the fat's surface area.

2.The pancreas secretes enzymes called lipases that attack the surface of each micelle and break the fats down into their parts, glycerol and fatty acids.

3.These parts get absorbed into the cells lining the intestine.

4.In the intestinal cell, the parts are reassembled into packages of fat molecules (triglycerides) with a protein coating called chylomicrons. The protein coating makes the fat dissolve more easily in water.

5.The chylomicrons are released into the lymphatic system -- they do not go directly into the bloodstream because they are too big to pass through the wall of the capillary.

6.The lymphatic system eventually merges with the veins, at which point the chylomicrons pass into the bloodstream.

Protein can't be turned into fat, but I'm actually having trouble finding out what happens if you eat more protein than your body can handle at once. Do you just pass it, or what?

My point is that even if I literally ate 2000 calories of refined sugar (assuming I didn't vomit) it simply doesn't make sense that somehow I stored a large proportion of the energy as fat and then did not immediately start burning that fat through natural processes. Your body CANNOT both make energy and store energy as fat with the same calories. If it could, it would be a perpetual motion machine, producing more energy than it consumes.

Another test outside of nutritional science is even easier. Does the person who wrote this idea profit from it? The answer is yes. Mark Sisson sells a metric shit ton of dietary supplements and Paleo Mayonnaise on his website He also sells certification in his nutritional philosophy. It costs $995. That's right, a thousand dollars.

So with all due respect, I disagree with you for the above reasons.
