The Carb-Appropriate Podcast. Episode 1. feat. Paul Cadman

I had so much fun chatting with Paul. In my opinion, he’s one of the few endurance coaches who has managed to meld personal experience and experimentation with an evidence-basis, and the organisation that comes from having been a successful businessman previous to becoming a coach in the endurance space.

How I met Paul and Paul’s background in health and performance

1:48 – Paul is a Graduate of the Holistic Performance Institute (Graduate Certificate in Holistic Performance Nutrition – Grad.Cert.HPN) find out more about the course here: http://www.holisticperformancenutrition.com/graduate-certificate.html

9:21 – Shout out to Joe McQuillan, senior lecturer at Waikato University, one of the unsung heroes of Low-Carb in NZ 😉

10:30 – Paul’s crazy experiments with MASSIVE doses of ketones, superstarch, and more. (You have to listen to this. It’s crazy!)
Paul has used Pruvit Keto//OS and Pruvit KetoMax and UCAN Superstarch extensively. He also uses ‘sodium pre-loading’ for events with Precision Hydration products. Check them out at www.nutritionstore.online

19:08 – Note: The main benefit of ketones in Paul’s opinion, is because it increases cognition. He’s also observed that in his elite level athletes…

31:22 – “The bike is where you have a really strong nutrition strategy to set you up for the run…” “About 10-15 km into the run…you put whatever you need to put into your body to get to the finish line…I don’t care what it is…”

32:26 – Metabolic flexibility? Is it about fat-adaptation, or truly being able to utilise whatever you put into your body. (Or are they the same thing?)

36:30 – What are some of the key mistakes that endurance athletes make?
Take home message: Experiment!

41:52 – Paul’s go-to resources:

48:00 – What are some of the non-fitness books or ‘go-to’ for Paul?
Planning AND being able to go with the flow is the key to success.

Cliff’s note: A great book for mental solidity and being able to keep moving forward is Extreme Ownership by Jocko Willinck and Leif Babin

All you need to know about Collagen. A mini-review

Touted for its anti-aging, and skin, hair, nail, joint, and gut-supporting properties, collagen hydrolysate is one of the hottest supplements on the market right now.

But are the claims justified?

Let’s take a look at what the scientific evidence says…
Overall, reviews of the evidence show that collagen hydrolysate has anti-ageing, anti-inflammatory, anti-oxidant, and joint-supporting properties.1, 2 When taken orally collagen hydrolysate is able to enter the body and accumulate in cartilage, where it increases the synthesis of connective tissue.3 Peptides from collagen that are beneficial to skin health have also been shown to be able to enter the bloodstream,4, 5 and effectively reach the skin as a result of oral collagen supplementation.6

Specific effects

A trial on 56 women aged 30-55 years, showed a significant improvement in skin hydration and elasticity in those taking just 2.5 g of collagen hydrolysate daily vs placebo.7 This effect has been shown to be dose-dependent, with results improved significantly with higher doses (5 g and 10 g).8

As little as 1200 mg per day of collagen significantly improves joint pain after 6-months.9

A 10 g dose of collagen, taken daily reduces pain, and improves joint mobility and function in people with arthritis,10, 11 and reduces joint pain and inflammation in athletes.12

Summary

So, collagen hydrolysate can help you to support skin and joint health, and reduce pain and inflammation, and encourage improved joint mobility.
