Q

What main principle is the blood type diet based on?

A

That the action of certain lectins have different effect on people with certain blood types. Lectins can cause agglutination of the blood.

e.g. if a type a drinks milk the body will immediately start the agglutination process in order to reject it

Q

Why are lectins harmful?

A

Some lectins can bind to the GI tract and cause inflammation

They can also bind with minerals, especially iron, calcium, zinc and phosphorous and inhibit their absorbtion.

Q

Why might ketones be beneficial in neurodegenerative disease?

A

Ketones are able to cross the blood/brain barriet as an alternate source of energy for the brain. Especially helpful where insulin resistance is a cause.

Q

What are the main principles of the
SCD (Specific Carbohydrate Diet)
and GAPs (Gut and Psychology syndrome diet)

A

-Improve the health of the digestive trace and microbiome
-Propose a causal link between GIT disturbance and auto-immune and allergic responses
-maldigestion of carbohydrates promotes the growth of pathogenic bacteria and yeasts which can cause or exacerbate raised intestinal permeability. This can lead to food intolerances, malabsorption and allergies

Why might this happen?

A

Nausea, muscle and joint pain, mucous, furred tongue, slow bowel movement, spots and rashes, headaches dizziness, stong emotions, fatigue, body odour, darker urine.

The body stores significant levels of toxins in adipose tissue as these toxines enter the blood stream. The more toxic the system, the greater the crisis. This is why a fasting preparation is important

Q

What is the eat-stop-eat fast also know as?

A

OMAD- one meal a day
24-hour fast

70
Q

What is the effect of fasting on cellular function

A

The activation of cellular stress pathways (hormesis) encourages the increased production of endogenous antioxidents and DNA repair mechanisms.
This ensures decreased oxidative stress in all cells of the body.

71
Q

By what mechanisms can IF lead to weight loss

A

-Metabolic shift to using fat for energy
-Reduction in insulin supports lipolysis and decreases lipogenesis

74
Q

What is BDNF?

A

Brian Derrived Neurotropic Factor. A protein involved in the growth and development of nerve cells.
