Carbs can Make you Fat? How does that Work?

A few people have asked me how it is that carbohydrates can cause weight gain, but eating fat doesn't tend to do so. The thing is, "calories in, calories out" is a myth. Unlike a car that simply burns gas, our bodies respond differently to different fuels. There are a few reasons that carbohydrates, more so than fat or protein, can cause weight gain:

It's easy to overeat carbohydrates.
Most carbs aren't very filling. Everyone who has ever eaten half a box of cereal, a bag of chips or box of cookies in one sitting, raise your hand. Ever eaten a stick of butter or a whole jar of mayonnaise at once? I didn't think so.

Carbs are addictive for some people. Dr. William Davis, a cardiologist, recommends a low-carb, wheat-free diet to all his patients. He reports that 30% of them go through wheat withdrawal.

Carbs can make you hungry. Eating carbohydrates raises your blood sugar, which causes your body to release insulin into the bloodstream. In some people, this is followed by a dip in blood sugar, which causes hunger.

Keep in mind, though, that eating too much of anything can cause weight gain.

Carbohydrates affect your insulin levels.
Again, eating carbohydrates causes your body to release insulin into the blood stream. This process is more complicated than simply overeating. Another blogger, Sami Paju, explains the process very well in his post "The How and Why of Weight Loss" on his blog SamiPaju.com, excerpted here. He also talks about diabetes and the physical differences between hunter-gatherers (the original low-carb people) and farmers (high-carb people).

This is what Drs. Michael and Mary Dan Eades say about insulin: "[It] regulates blood sugar... It controls the storage of fat, it directs the flow of amino acids, fatty acids, and carbohydrate to the tissues, it regulates the liver's synthesis of cholesterol, it functions as a growth hormone, it is involved in appetite control, it drives the kidneys to retain fluid, and much, much more." In other words, insulin is very likely the most important hormone when it comes to your metabolism.

As stated above, insulin controls nutrient storage and its main purpose is to get excess sugar, amino acids and fats out of the blood and into the cells. In the context of this article, the take-away message is that the higher your insulin levels, the more inclined your body is to store nutrients as fat. And notice, that I said "nutrients" instead of "fat". Our bodies will turn the excess protein and carbohydrate into fat. You can eat all the no-fat or low-fat food in the world and still accumulate body fat! On the other hand, lower insulin levels promote the usage of stored fat, leading to weight loss.

Carrageenan: A Sickening Thickener. Is it a Migraine Menace?

Let me tell you about my ride in an ambulance last night. I woke up at six o'clock from a nap with a mild headache. I ate dinner and took my vitamins, along with a couple of extra magnesium pills. Since magnesium helps my TMJ flare-ups, I thought it might help my headache. Then I went to see my mother. A few hours later, I had a severe headache, sinus pain and nausea. During a brief respite from the pain, I left for home, but less than a mile later, I got out of my car and threw up. A cop, Officer Fisher, pulled up behind me and asked if I was okay. He believed me when he said I hadn't been drinking, but he said I seemed lethargic and he wanted the paramedics to see me. (Later he mentioned that a man he'd recently stopped was having a stroke.) Thinking I had a migraine headache, the paramedics wanted to take me to the hospital. But since I knew that doctors don't know what causes migraine headaches, and I didn't know what effect their medicine would have on m...

Blog Lineup Change

Bye-bye, Fathead. I've enjoyed the blog, but can't endorse the high-fat, high-carb Perfect Health Diet that somehow makes so much sense to some otherwise bright people. An astrophysicist makes some rookie mistakes on a LC diet, misdiagnoses them, makes up "glucose deficiency," and creates a diet that's been shown in intervention studies to increase small LDL, which can lead to heart disease. A computer programmer believes in the diet and doesn't seem eager to refute it because, perhaps, scientists are freakin' liars and while he's good at spotting logical inconsistencies, lacks some intermediate knowledge of human biology. To Tom's credit, he says it's not the right diet for everyone, but given the truckload of food that has to be prepared and eaten, impracticality of following it while traveling (or even not traveling), and unsuitability for FODMAPs sufferers, diabetics and anyone prone to heart disease (i.e., much of the population), I'm...

Why I've stopped eating fermented foods

I'm finally getting answers about weird health problems that have kept coming and going over the years for no reason I could ever explain: pounding heart, bloating, insomnia, heat intolerance, intolerance of high-fat meals, and getting winded easily even though I'm physically fit. These health problems all came roaring in at once this spring when I did a huge landscape project, pushing through it even while I had a cold. The yard looks fabulous, but I ended up with A three-week cold Post-viral syndrome for another few weeks An ongoing cough  Insomnia (tired but wired late at night) A puffy face, especially in the morning and after eating foods I’d previously tolerated (including SIBO yogurt) 6 pound weight gain TATT (tired all the time) Being easily winded Having a hard time cooling off Being sensitive to sunlight Grok (X’s AI feature) said this could be mast cell activation syndrome (MCAS). Mast cells are immune system cells that put out pathogen-fighting and other substances ...
