MI Take

Infinite Protein Games EP 137

Episode Summary

In our season 4 premier of the podcast we talk about what happens when you consume 100 grams of protein in one meal, infinite games, the false hope of stability, and why you shouldn't waste a second of your life.

Episode Notes

Introduction: Hey Everyone, I am Brad Dieter, the COO of Macros Inc, a nutrition and fitness coaching company and this is MI Take, a podcast that discusses current events in nutrition, the business side of the health and fitness industry, and a little of everything in between. Let’s dive into it. 

Nutrition Insights: Protein in a Single Meal. 

The anabolic response to protein ingestion during recovery from exercise has no upper limit in magnitude and duration in vivo in humans

• The context of this study
  • 0, 20, 40 study - tromellen 2019
  • 0, 40, 70 study - kim et al 2016
  • Bolus vs spaced out feeding - areta 2013 study 
  • Anabolic window
• They fed people 0, 25, and 100 grams of protein.
• Amino acid levels in the blood remained elevated for up to 6 hours post the 100 grams but not quite that long for the 25 grams.
• PS and PB were measured and protein synthesis was highest in the 100 grams as was the net balance. 
• FSR or essentially the rate of muscle accretion was highest in the 100 grams, which was elevated out to 6 hours and was highest in the 100 grams.
• The anabolic response is > 12 hours.
• No limit to protein-derived amino acid bioavailability and subsequent tissue incorporation
  • We have previously estimated that the ingestion of 20 g protein results in 10% (2 g) of the ingested-protein-derived amino acids to become incorporated in skeletal muscle tissue throughout a 6-h postprandial period.4 In the current study, we calculated that 12%, 15%, and 18% of the ingested protein was incorporated into skeletal muscle following ingestion of 25 g protein throughout 4-, 8-, and 12-h periods, respectively
  • Quite a lot ends up in circulation with ~10-15% in muscle post meal. 
  • As you increase protein in a meal more of what gets incorporated into your muscle comes from what you ate, not the free amino acid pool.
