Learning goals case 9
1. What are low carb, high fat diet and how do they affect our health?
In a low carb diet fat ≥40% of energy. A ketogenic diet is a special type of diet with fat typically
≥70% of energy.
Normal diet = 40 -50% carbs and 20-30% fat
In low carb high fat diet = 10-30% carbs and 60% of fat.
Concerns : Intake fibres and vitamins are lowered and cardiovascular disease risks and kidney
problems. Of course you have to eat the unsaturaded fats, quality of fat is important.
Ketogenic diet = fat intake of more than 70% of energy, favourable for people with pre-diabetes
because then the problem with glucose storage is less!!!!
The physiological mechanism:
- As dietary carbohydrate is replaced by fat, postprandial peaks in the blood concentrations of
glucose and insulin decrease, glucagon secretion increases, and metabolism shifts to a
greater reliance on fat oxidation.
- This hormonal and metabolic response is associated with
weakened oxidative stress and inflammatory responses after eating
reduced hormone resistance (insulin, leptin etc.)
improvements many features metabolic syndrome effects
