My experiment with the Bulletproof® protein fasting
A while ago I listened to a lecture by Dave Asprey in the Living La Vida Low Carb podcast. While I don’t agree with everything Asprey says, when he mentioned his protein fasting protocol I remembered hearing solid stuff related to this concept from Mat Lalonde. It made sense, so I decided to give it a go. According to the Bulletproof® Diet‘s infographic, the Bulletproof® protein fasting is “a biohack used occasionally to get a greater reduction in inflammation. About 1-2 times a week, limit your protein intake to 15-25g to help cleanse your inner-cells without muscle loss. To keep you full and energized, consume a cup of Bulletproof® Coffee in the morning and have high fats and moderate carbs throughout the day. For optimal results, follow the green portion of the diet [non starchy veggies] and limit carbohydrates to the afternoon and evening.”
That inner-cell cleansing process is call autophagy and is triggered when fasting and when consuming very little protein. Asprey says that when he started tinkering with this approach he was consuming about 25g of protein found that below 15g gave him better results. I didn’t measure my intake (mostly because I know there’s a lot of variability in the nutrient content of foods) but I tried to stay away from everything that has some protein in it, such as dairy (other than butter), eggs and nuts.
My experiment ran for 5 weeks and I felt it helped reset my body, particularly around the Xmas holidays. I’m travelling at the moment, but I see no reason to not resume this approach once I’m “back to normal”. Below is my food/activity log.
