Something to consider if we think carnivore is a fast-mimicking diet.

📖@CarnivoreCure excerpt: “Human growth hormone (HGH) helps to build muscle and bone mass, and fasting increases HGH production.

🍽Fasting promotes the preservation of muscle mass to help ensure human survival. A study published in the Journal of Clinical Endocrinology and Metabolism found that levels of growth hormone increased fourfold after just two days of fasting.337

Fasting also helps with autophagy.

🦠Fasting promotes the cellular cleansing process that breaks down and recycles damaged molecules and cells (autophagy). There is a similar process called apoptosis (programmed
cell death) and necroptosis (another programmed cell death).

🛡All these processes clean out old, damaged cells and make room for new, healthier cells (reference Figure 18.5)338

🔥The most effective way to turn on autophagy is fasting. Studies in rodents show it takes about 48 to 72 hours for autophagy to be activated.

💡Fasting becomes very individualized as someone fasting for weight loss should fast differently than someone fasting for autophagy.

🥩Carnivore and the long stretches without eating can turn on autophagy naturally, but proteins and amino acids decrease the need for activating autophagy (reference Table 18.8).

🐄When we eat protein, we turn on mTOR (master controller of protein synthesis and turns on cell growth) and essentially turn off autophagy.

⚖️Excess calories can also suppress autophagy, increase mTOR, and turn down AMPK (a master switch regulating energy metabolism and fat burning).

❓This begs the question: if you have one meal a day—of over 2,500 calories—will you ever turn on the benefits of autophagy?

⛑It’ll likely depend on how long you fast until your next meal, but this is another reason I’m not a big fan of having only one meal a day—bad for digestion and bad for cell cleaning.”
