The Fasting Playbook: Master Intermittent, Water, and Dry Fasting for Longevity | Ep #303

Intermittent Fasting

Intermittent fasting offers various schedules like 16/8, 18/6, and 20/4, each with unique benefits. Nathalie Niddam emphasizes the importance of aligning fasting with one's lifestyle, suggesting that skipping dinner might be easier for those living alone 1. She advises prioritizing nutrient-dense foods, especially as the eating window shortens, to maximize health benefits 2.

Intermittent fasting is just extremely beneficial. It's good for metabolic flexibility, it's cardio protective, it helps with metabolic syndrome.

--- Nathalie Niddam

Nathalie also highlights the potential for improved metabolic health and reduced abdominal fat when fasting is done correctly 2.

   

Water Fasting

Water fasting, ranging from 24 to 72 hours, can significantly enhance metabolic flexibility and induce nutritional ketosis. Nathalie Niddam explains that during this fast, the body shifts to using ketones for fuel, which have anti-inflammatory effects 3. She stresses the importance of consulting a healthcare provider before attempting longer fasts, especially for those with blood sugar issues 4.

Fasting can be the most cost-effective, the most powerful single intervention that we have at our fingertips in order to improve our metabolic health.

--- Nathalie Niddam

Water fasting also aids in detoxification and hunger management, making it a potent tool for health improvement 3.

   

Dry Fasting

Dry fasting, though intense, offers remarkable benefits like increased autophagy and cellular repair. Nathalie Niddam notes that even a 24-hour dry fast can stimulate detoxification and improve skin and gut health 5. However, she cautions that dry fasting should be medically supervised, especially for extended durations 6.

The benefits of dry fasting is that you see an increase in autophagy and cellular repair. We get a decrease in inflammation in part because of those ketones.

--- Nathalie Niddam

Nathalie advises that those attempting dry fasting should be aware of their body's signals and not push beyond their limits 6.

   

Alternate Day Fasting

Alternate day fasting involves cycling between normal eating and reduced calorie intake, promoting metabolic health and weight management. Nathalie Niddam describes how consuming around 500 calories on fasting days can still provide substantial health benefits 7. This method helps normalize blood lipids and reduce inflammation over time 7.

You get that push and pull, right? You get feasting and fasting and feasting and fasting.

--- Nathalie Niddam

Nathalie emphasizes the importance of maintaining a clean diet even on non-fasting days to maximize the benefits of this approach 7.

   

Fasting Mimicking Diet

The fasting mimicking diet (FMD) offers a way to gain fasting benefits without complete food abstinence. Nathalie Niddam explains that FMD involves low-calorie, low-protein meals over five days, enhancing autophagy and cellular repair 8. Developed by Dr. Valter Longo, this diet has shown significant improvements in metabolic health and longevity 8.

We see longevity and healthspan go through the roof because metabolic health improves, metabolic flexibility improves.

--- Nathalie Niddam

Nathalie suggests integrating peptides and GLP1s to amplify fasting results, while maintaining a nutrient-dense diet 9.
