How We Get Energy from Food
April 20, 2015
Natural Hygiene says energy comes from sleep, not from eating. I believe energy pours into me from multiple sources, especially when I body-surf in huge ocean waves!
When you need energy, EAT energy. Eat living food still growing in the moment you eat it. That's eating on the level of physics. Life energy in food feeds the life energy in you! You main-line into Energy itself.
On the chemical level, our oxidative system converts food into energy via two cycles:
- the Anaerobic Glycolysis Cycle in our cell fluids
- the Aerobic Krebs Cycle in our mitochondria
Do you see the TWO energy cycles making ATP?
(1) Anaerobic in the Cell fluids, and (2) Aerobic in the Mitochondrion

|Anaerobic Glycolysis Cycle||Aerobic Krebs Cycle|
In the cell's watery area (its cytoplasm)
In the mitochondria (organelles or energy factories in each cell except our red blood cells)
To make energy molecules called ATP, first the carbohydrates (glucose in image above), fats (fatty acids) and proteins (amino acids) we eat are broken down into a form of acetic acid called acetyl CoA.
Then acetyl CoA passes on into the Krebs Cycle.
The Krebs Cycle functions at its best only when it gets the right number of acetyl CoA molecules from Carbohydrates, the right number from Fats, and the right number from Proteins.
If Krebs gets too many – or too few – CoA's from carbohydrates, in relation to the CoA's it's getting from fats and proteins, then your energy levels drop and you feel worse.
Conversely, if you eat right for your Krebs, you enjoy a contented feeling of well-being. You're full and satisfied.
Problems in Producing ATP
The problem occurs in our first cycle – the glycolysis cycle. When a molecule of glucose enters a cell to be used for energy, it's grabbed by an enzyme in the cell's fluids that's working for the glycolysis cycle. This begins the breakdown of glucose into acetyl CoA.
|Slow Oxidizers - Carb Types||Fast Oxidizers - Protein Types|
|Glycolysis cycle is slow – you have fewer enzymes working more slowly||Glycolysis cycle is quick – you have more enzymes working at top speed|
|As a result, too little acetyl CoA from glucose and too much acetyl CoA from fats and proteins||You get the opposite, too much acetyl CoA from glucose and too little acetyl CoA from fats and proteins|
|Need more Carbohydrates to compensate for slower production||Need fewer Carbohydrates to slow down production|
|Tendency to be alkaline||Tendency to be acid|
|Eat low protein–30-35% of diet; high carbohydrate–55-60%; and low fat–10-15%||Eat high protein–50-55% of diet; low carbohydrate–30-35%; and medium fat–20-25%|
|Fruits + vegetables are helpful because their acid direction in the oxidative-dominant person will balance your constitutional tendency to alkaline; so all fruits, vegetables and undiluted raw juices are good for you; and all grains; natural sweeteners like raw honey, or maple syrup and brown rice syrup (these syrups are cooked); yogurt from rice milk or oat milk is good (yogurt turns cooked milk into a raw food) although in time machine milk and animal milk is best limited or eliminated||Excess fruit + vegetables in relation to nuts + beans will make you more acidic; you benefit from nut and seed milks, avocado, spirulina, and pulses (sprouted soya, lentil, mung and other beans); also eat foods high in purines (chlorella, brewer's yeast, bee pollen); minimize foods high on glycemic index, e.g. wheat and potatoes, or rice cakes. Vegetables are low G.I. so good for you! Minimize sweet fruits (bananas, grapes) and dried fruits, and dilute all juices except high-protein green drinks|
|Mixed oxidizers need medium protein, 40-45% of diet; medium carbohydrate, 40-45%; and medium fat, 15-20%. Their tendency is to be optimal pH 7.46.|
|Dr Gabriel Cousens gives the above advice based on his clinical research. But most scientific research says that our fat intake should not be higher than 10-15% of calories. That's about a handful of nuts or tablespoon of seeds (like sunflower, pumpkin or sesame) or one avocado a day. See What To Eat In A Rawfood Diet.|
When to Eat for Best Energy
We circle through three cycles a day in harmony with the sun's passage – it's our circadian rhythms:
- Cleansing and elimination cycle from 4am to 12 noon
- Digestion from noon to 8pm, so best to eat main meal between noon and six, and
- Assimilation cycle is 8pm to 4am, that's when our cells do their repair work.
If you want fewer wrinkles, get more sleep! Cells can't renew at night if you're busy flogging them to keep you going.
And drink alkaline water for its billions of anti-oxidants. They help to stop the free radical chain reactions that cross-link proteins in our skin cells, causing them to wrinkle.
What Is the Oxidative System?
Skip this part if you don't like dry science.
Just as your heart is the core of your circulatory system (and of your compassion and wisdom) so the mitochondrion is the core of your energy-generating system called the oxidative system.
Every cell has hundreds or even thousands of sausage-shaped organelles called mitochondria. Each one is an energy factory. In a building-sized cell, the mitochondria would be a bit larger than a living-room sofa.
In your other systems, the core organ (such as heart, lungs, liver) is a building of millions of bricks called cells. In contrast, with your oxidative system the core organelles are inside each brick. You have quadrillions of mitochondria, hundreds in every one of your trillions of cells.
|Cycle||Where It Takes Place||What It Does||What the Result Is||How We Use the Energy|
|1. Glycolysis, stage one – no oxygen is needed for the chemical reactions in glycolysis, so we call it anaerobic||in each cell's watery area known as the cytoplasm||Enzymes split each glucose molecule entering the cell, into two molecules of pyruvic acid||this splitting of glucose gives enough energy to make 2 molecules of ATP||Our glycolysis cycle gives our muscles a rapid source of energy. It's great for that final burst of speed in a race. Fluoride inhibits glycolysis, another good reason to drink alkaline water which flushes away a lot of fluoride in the acid water|
|1. Glycolysis, stage two||also in the cytoplasm||the two pyruvic acid molecules are then converted into a form of acetic acid called acetyl CoA||Acetyl CoA enters into the mitochondria|
|2. Krebs Cycle, also known as citric acid cycle||in organelles called mitochondria, in each cell||Enzymes strip hydrogen atoms from the acetyl CoA molecules that enter from the above glycolosis cycle – so the enzymes free up hydrogen atoms from the carbohydrates, fats and proteins we eat||the stripping of hydrogen from one molecule of acetyl CoA gives 2 molecules of ATP and frees up 16 spare hydrogen atoms. The free hydrogen atoms enter into the Electron Transport Chain||
Your capacity for aerobic synthesis of ATP is crucial to your performance in activities lasting longer than 2 minutes. Carbon monoxide inhibits the electron transport chain, so don't ever exercise in traffic.
OXYGEN is essential, another good reason to drink high-oxgen alkaline water to give you more energy :)
|3. Electron Transport Chain (not shown in graphic), also known as oxidative phosphorylation – oxygen is needed here, so we call it aerobic||also in the mitochondria||Electrons from the hydrogen atoms are transferred to oxygen atoms **||the complete oxidation of glucose to carbon dioxide and water in the Glycolysis cycle, Krebs cycle and Electron Transport Chain yields 36 molecules of ATP|
** Like a bucket brigade, the electrons from hydrogen are passed along a chain of reactions until they reach the end of the line, where they combine with oxygen to form water.
That's why we say our food is "oxidized" to give energy because in the end, oxygen is grabbing its electrons.
