MISUNDERSTANDING OF WEIGHT GAIN
- Obesity links tons of diseases together
- Dr. Fung started by asking: What causes obesity?
- The Aetiology of Obesity Lectures
- Sugar is the enemy, not calories
- When you eat less calories, your energy expenditure (and thus
fat/fuel usage) goes down
- You simply get hungrier
- When you eat less calories, your energy expenditure (and thus
fat/fuel usage) goes down
- Takes time to lose the weight
- Cortisol is a stress hormone -- encourages getting fat
- Leptin -- produced by fat cells, regulates how much fat is in
the body
- If you have lots of fat, leptin is released and tells your brain to stop gaining more weight
- When you are quite fat, your body stops responding to leptin
- Secondary hormone -- doesn't pass the causal test
- Ghrelin is another one of these secondary hormones
- No lasting effect so doesn't pass the causal test
FASTING
- People always ask Vinnie about IM fasting
- Intermittent fasting should happen every day
- 3 meals a day -- fast in between
- literal "break - fast"
- Snacks don't allow your body to process everything
- Shorter fasts are not enough
- Insulin levels not sustainably down
- We obsess to much about what we are eating, we need to think about when we are eating
