Does Your Body Make Cholesterol? Science Says YES

Cholesterol  is made during the inter-conversions of nutrients from: protein, carbohydrate, and fat, to energy, by Acetyl Coenzyme A. Here are three Science based quotes  to support this little known fact.

QUOTE #1 – “Cholesterol is synthesized (processed) from Acetyl Coenzyme A in Three Stages” says science.

QUOTE #2 – Acetyl CoA is the fuel for the citric acid cycle (THE ENERGY MAKING PART INSIDE YOUR BODY). This important molecule is formed from the breakdown of glycogen (the storage form of blood glucose), fats and many amino acids.”

QUOTE #3 – “85% of cholesterol is made from acetyl Co A (acetyl co enzyme A), by your liver. About 15% of blood cholesterol comes from the diet” says Marieb & Hoehin’s, Human Anatomy & Physiology Tenth Edition, Chapter 24 Nutrition, Metabolism, and Energy Balance, on Page 943.

  1. FIRSTLY – This means the amount of cholesterol that comes from food sources like, animals and poultry, including eggs is only 15%.
  2. SECONDLY – This means that 85% of cholesterol in your body, is made INSIDE YOUR BODY by your own metabolism, by acetyl co-enzyme A.

Acetyl Coenzyme A is the name and link that science uses when answering the question – does your body make cholesterol? This provides the link to investigate, and learn, how your body makes cholesterol.

What is Acetyl Coenzyme A’s Function in Your Body?

Acetyl Coenzyme A is a processor in your liver which converts nutrients. Its function, is to speed up the inter-conversions of nutrients from: carbohydrates, fats, proteins, vitamins and minerals from your diet for use as energy and then to cholesterol. The shortened name of Acetyl Coenzyme A is Acetyl Co A.

Here is an Image of Foods that are Mixed Together  by this Process in Your Liver to Make Cholesterol

The inter-conversions of every type of food, like the variety in the above image are mixed together.

The next image called “Stages of Metabolism” shows in diagram form, how everyday: foods, snacks, condiments and drinks are the ingredients Acetyl Co A uses to make energy and then cholesterol. ‘Acetyl Co A’ is located in the middle, and near the top, of the green rectangle linking down to the ‘Citric acid cycle,’ which is where your energy and cholesterol are made. The three names and colors across the top are listed here:

#1. PINK – Proteins link in from the left. Sources of complete protein are mostly meat, poultry, eggs, fish and sea food. Proteins functions are structural growth and repair of: keratin in skin, collagen & elastin in connective tissue, and muscle protein. In addition, functional proteins such as enzymes and some hormones regulate a variety of functions but also act as a building.

Proteins are the first of the 3 food groups, mixed together to make cholesterol.

#2. BLUE – Polysaccharides: Glucose, Fructose, and Galactose, (Carbohydrate sugars), link down from the center. “All carbohydrates came from plants. Sugars (monosaccharides & disaccharides) come from fruits, sugar cane, sugar beets, and milk. The polysaccharides are found in grains (flour & pasta) and vegetables.

Carbohydrates families of starches and sugars are the second of the 3 food groups, mixed together to make cholesterol.

#3. YELLOW – Lipids (Fats) link in from the right. Fat sources are: trans fats from – vegetable lard, margarine, fake butter, vegetable & plant omega 6 oils. Saturated fat from meat & dairy, coconut oil, olive oil and omega 3 essential fats from fish and flax seed.

Fats and oils are the third of the 3 food groups, mixed together to make cholesterol.

Acetyl CoA is Link in Stages of Energy Metabolism That Makes Cholesterol

Interconversions of Carbohydrates Proteins and Fats

Stages of Metabolism

Explanation of Stages of Metabolism

The biochemical processes mentioned in the left hand side, of the ‘Stages of Metabolism’ image from, are not easily understood by most of us…

Can you see the name Acetyl CoA in pink, with a pink downward arrow to Citric acid cycle, near the top and center of the green rectangle shape? – GREAT.

Here is a simpler explanation of: Stage 1, Stage 2, and Stage 3:

  • STAGE 1 – Proteins, Polysaccharides (Glucose, Fructose & Galactose) Carbohydrate sugars, and Fats from your food, when eaten at any time, are mixed together and digested in your gastrointestinal tract.
  • STAGE 2 – This happens in your cells. Newly digested food (protein, carbohydrate and fat) are made into smaller parts called molecules.
  • STAGE 3 – This happens in the energy making part of your body called the mitochondria.

The Stages of Metabolism image identifies Acetyl CoA as the digestive processor of every food type that you eat. This quote from the Marieb & Hoehin, Human Anatomy & Physiology Tenth Edition text, in Chapter 24 Nutrition, Metabolism, and Energy Balance, on Page 943, supports the information.

Here is a reminder with this quote: “85% of cholesterol is made from acetyl Co A (acetyl co-enzyme A), by your liver. About 15% of blood cholesterol comes from the diet”

Acetyl CoA is Link Between Two Metabolic Pathways

The relationships, between your energy metabolism (the Acetyl Co A processor), and it’s link to cholesterol metabolism, is difficult to find on google as an easy to understand image.

Acetyl CoA is the Source for Making Cholesterol in Your Body

The cholesterol making function of Acetyl CoA, and link, is shown in the twenty-year-old image called ‘Acetyl CoA – The Center of Lipid Metabolism’ by James Baggott Ph.D. 1997, 1998.

PRECURSORS are the things that happen before:

This image identifies glucose from the carbohydrate sugar families, and the amino acids from proteins are named. Fats are not named here, but their link is shown in yellow, with the name Lipids, in the Stages of Metabolism image. Then the PRECURSOR items link down with arrows to Acetyl CoA.

The Center of Cholesterol’s and Fats Metabolism is Acetyl CoA

by James Baggott Ph.D. 1997, 1998 –

Vital Fat Based PRODUCTS Made by Your Body

Products made during this process provide essential functions in your body. Unknown to many, your body cannot survive without out these vital fats. Fats help your body absorb fat-soluble vitamins, A, D, E & K.

Cholesterol is listed underneath Acetyl CoA, down to the right, with linking arrows to steroid hormones (sex hormones) and bile salts (fat emulsifier). Cholesterol is the structural bases for manufacture of steroid fats and is part of every cell in your body.

Energy is made from – CO2 + H2O + energy (ATP), your body’s energy producer is listed directly below Acetyl CoA.

Triglycerides – Are also called neutral fats. They have essential functions in your body.
They are located in storage sites all over your body. Their functions are to, insulate and protect vital organs and provide storage for energy. They are a raw ingredient building block. Their supplies are boosted by carbohydrates (sugars and starches) being stored as fat by insulin.

Phospholipids – Are located in your brain and nerve cells, plus are a construction ingredient of every cell in your body. They conduct electrical currents along nerves so you can feel sensation and touch.

Eicosanoids (Prostaglandins) – Are deeply embedded in your immune system. They control and, regulate up or down: child birth contractions, inflammation, fever, blood pressure, and blood clotting.

The Conclusion to – Does Your Body Make Cholesterol? – Science Says YES


Do you believe food sources such as: saturated fat, eggs, animal and poultry meats, contain the ingredient  cholesterol, that is responsible for your cholesterol levels, and the cholesterol content of your body?

Do your count fat calories or eat a low fat diet? – CHECK OUT – What is Cholesterol? – NEW Research

FACT – THREE scientific references say – cholesterol (LINK) is made during the inter-conversions of nutrients from: protein, carbohydrate, and fat, to energy, by Acetyl Coenzyme A in your liver.

FACT – Acetyl CoA is the link between your body’s energy conversion and cholesterol.

FACT – Acetyl CoA is the link, in the Stages of Energy Metabolism. that leads to cholesterol’s manufacture by your body.

FACT – Other vital fat based ingredients and nutrients are converted by this same method.

Please share what you think? – Did any of this make sense to you? – Is there some way of helping you understand the Cholesterol is Made in Your Body, idea?

    The information provided has convinced me that cholesterol is indeed produced within the body, and appears to have a vital role in its normal functioning. I’d like to learn more about the implications of this. What levels of cholesterol might be too low and is there an upper limit that is too high? Also I see some general information on this post, but what is the specific function of cholesterol in the body?

    Thanks for the informative post!

      Hi Nick thanks so much for finding my post convincing. My next post ‘9 Ways Cholesterol is Needed by Your Body’ indicates what cholesterol’s specific functions are. Then there will be a post on the dangers of low cholesterol. Then I’ll show you the style of diet some Cardiologists are sharing.
      Thank you for contributing in the way that you have.


    My goodness! Exactly what can I eat?? So I can’t eat peanuts which I love especially peanut butter, can’t eat bread, or any carbs for that matter. All sugar is out, huh? I recently switched from canola oil because it’s bad over to avocado oil but apparently all oil is bad. My cholesterol as a week ago is 330! I’m starting to only eat once per day to try to reset my body but I need specifically to know what can I eat I don’t want to die! I don’t want to have a stroke!

      Hey Jacqueline,

      Is the peanut butter made only from peanuts? – or is there added veg or plant oil on the label?
      It is not healthy ancestral type fat or cholesterol that triggers your health problems. But, industrial made oils & margarine, PLUS, the amount of sugars & starch you eat in carbs.
      Research a low- carbohydrate healthy fat, or keto type diet, only then can your stop eating hidden sugars & starch hidden in healthy food.

      Get into your get-well journey and get well
