Hört talas om Dave Asprey? Mannen bakom Bulletproof (coffee, diet, podcast, boken)? Jag har trott att han var ännu en förespråkare av highfat no carb, men det är ju helt fel! Snubblade över guidelinjerna till the Bulletproof diet (som är väldigt snarlika de Paul Jaminets skriver om i The perfect health diet) och där nämdes även proteinfasta som ett verktyg för att optimera hälsa och prestation. Läs och begrunda

By protein fasting once a week, you are essentially allowing your body a day to use its digestive machinery to perform self-maintenance. This is because dramatically lowering your protein intake once a week induces autophagy – or, literally translated, self-digestion. Yes, you heard it right: this means you’re eating your own protein and fat!

This is important not just for fat loss, but also for your cellular repair functions. Your enzymes from your pancreas and liver, in addition to breaking down and excreting toxins, have a secondary role of removing debris from the cells in your body.

Protein fasting also improves mitochondrial function, which results in better sleep over time.

Såhär funkar det:

The body’s natural cleaning process (autophagy), which recycles the junk in your cells and turns it into energy, is the cellular equivalent of burning your trash to stay warm. Over time, cells accumulate dead organelles, damaged proteins, and oxidized particles that interfere with cell function and accelerate aging. Autophagy is the body’s method of clearing out this clutter, meaning it helps keep you young. Clearly, autophagy is something you want your cells to do well in order to look, feel, and perform your best.

Autophagy is required to maintain muscle mass, and it inhibits muscle breakdown in adults.[iii] If you are interested in staying younger and building muscle by spending less time working out (and who isn’t?), of course it makes sense to hack autophagy. Let’s look at the two main signals for the body to turn on autophagy. The first is fasting.[iv] This was one of the reasons you’ll see such amazing results with Bulletproof Intermittent Fasting as well.

It turns out there’s an even better way to turn on autophagy, and that’s by occasionally limiting protein consumption. When you do this, you force your cells to find every possible way to recycle proteins. In their search, they bind and excrete toxins that were lurking in your cell’s cytoplasm, the gel-like substance enclosed within the cell membrane. It’s like taking your car to the car wash and having it deep cleaned.

Såhär går det till:

Protein fasting once per week means you you eat virtually no protein: limit your protein to 15 grams or less per day. To keep you full and energized, consume a cup of protein-free Bulletproof Coffee in the morning and have near-zero protein, high fats, and moderate carbs throughout the day. For optimal results, limit carbohydrates to the afternoon and evening.

Låter ganska sunt eller hur?! Både vad gäller hälsa, miljö, plånbok och prestation. Jag kommer köra igång med det här asap, kanske redan nästa vecka. Är småbrydd över hur jag ska kombinera detta med mina carbnites, men det ger sig säkert.

I övrigt rekommenderar jag Aspretys blog, eller hans Bulletproof podcast. Lika vettig som Chris Kresser, Paul Jaminet och Mark Sisson!
