Endocannabinoid System

  • The ECS regulates energy and fat balance in the body
  • CB1 receptors influence appetite, fat storage and energy expenditure
  • High omega-6 intake keeps the ECS overactive
  • Omega-3 fatty acids help restore balance
  • Lifestyle (exercise, sleep, fasting) normalizes the system

The endocannabinoid system is a biological regulatory system that helps the body maintain internal balance.

ComponentFunction
Anandamide and 2-AGEndogenous cannabinoids
CB1 receptorsMainly in nervous system; influence appetite, mood, energy expenditure
CB2 receptorsMainly in immune system; regulate inflammation and tissue repair
EnzymesForm or break down cannabinoids

The functioning of the ECS is strongly related to the fatty acids in the diet.

Linoleic acid — the main omega-6 fatty acid from seed oils (sunflower, corn, soybean oil) — is converted to arachidonic acid, the building block of endocannabinoids.

With high omega-6 intake:

  • ECS activity increases
  • CB1 receptors become more active
  • Fat storage increases

EPA and DHA from fish or algae work oppositely and help restore balance.


The CB1 receptor is the main link between diet, brain and metabolism.

LocationEffect of CB1 activation
BrainIncreases appetite, makes food more attractive
LiverStimulates fat storage
Adipose tissueDecreases fat burning
MusclesLowers energy expenditure

Result: A body that more easily stores fat.


The ECS evolved to promote survival.

When food was abundant:

  • CB1 activation stimulated appetite and fat storage
  • Reserves were built for scarcity
  • The system responded to external food signals (‘exostatic eating’)

A healthy lifestyle helps normalize the ECS:

InterventionEffect
Limit omega-6Less seed oils and processed food
Increase omega-3Fatty fish or algae
ExerciseStrengthens ECS regulation
Stress reductionNormalizes CB1 activity
Sufficient sleepSupports hormonal balance
Natural lightImproves day-night rhythm
Periodic fastingRestores CB1 sensitivity

Veelgestelde vragen

What is the endocannabinoid system?

The ECS is a biological regulatory system that maintains internal balance. It consists of endogenous cannabinoids (anandamide, 2-AG), receptors (CB1, CB2) and enzymes. It influences appetite, mood, energy expenditure, inflammation and tissue repair.

How does diet influence the ECS?

Omega-6 fatty acids (from seed oils) are converted to arachidonic acid, the building block of endocannabinoids. High omega-6 intake increases CB1 activity and promotes fat storage. Omega-3 fatty acids (from fish) work oppositely and restore balance.

What does the CB1 receptor do?

CB1 is the link between diet, brain and metabolism. Activation increases appetite, stimulates fat storage in liver and adipose tissue, and lowers energy expenditure in muscles. An overactive CB1 makes the body more easily store fat.

How do I restore balance of the ECS?

Limit omega-6-rich seed oils and processed food, increase omega-3 from fatty fish, exercise regularly, reduce stress, sleep enough and use periodic fasting or longer eating breaks to restore CB1 sensitivity.
