This is an "open discussion" between Prof. Tim Noakes and Martin MacDonald on the topic of carbohydrates, insulin resistance and body fat.

Prof. Noakes obtained an MBChB degree in 1974, an MD in 1981 and a DSc (Med) in Exercise Science in 2002. In the early 90s, Noakes teamed up with Morné du Plessis to drive the founding of the Sports Science Institute of South Africa (SSISA).

Prof Noakes has published more than 750 scientific books and articles. He has been cited more than 16,000 times in scientific literature, has an H-index of 71 and has been rated an A1 scientist by the National Research Foundation of South Africa for a second 5-year term. He has won numerous awards over the years and made himself available on many editorial boards.

After his research convinced him that a high fat, low carb diet is the healthiest option for many, Prof Noakes founded The Noakes Foundation in 2012. Prof Noakes retired as Professor of Exercise and Sports Science at the University of Cape Town (UCT) in 2014 and is now an Emeritus Professor at UCT. While his career has seen him involved in some controversial circumstances, love him or hate him, you cannot deny his contributions to scientific research.

Martin is a clinical performance nutritionist and the founder of Mac-Nutrition, a thriving nutrition consultancy boasting sought after long-term internship and weekend mentorship programs. He has also developed Mac-Nutrition Uni, the UK’s first ever evidence-based, nutrition course that can be completed online.

Martin has worked as a performance nutritionist in elite sport with British Weight Lifting, Derby County Football Club, English swimming and other elite sport organizations.

He has lectured at the University of Derby and has guest lectured on the prestigious MSc Sport and Exercise Nutrition course at Loughborough University.

In This Episode We Discuss:

Should carbohydrates be restricted for weight loss? weight maintenance? health?
Confusing messages given to the public surrounding nutrition
Do insulin resistant people need to be very low-carb?
Does LCHF mean less hunger, and therefore better long-term results?

0:00.0	Yeah, I think the most important point is that if you're insulin resistance, you intolerant of carbohydrate.
0:15.0	And that every time you eat carbohydrate, you hypersecrete insulin.
0:19.0	And that that then causes all the complications of
0:22.2	chronic diseases that we face today, the obesity, the diabetes, the cancer, probably the
0:28.8	dementias.
0:32.0	It's really, really key to understand the difference between high insulin. If you're consuming
0:37.1	lots of carbohydrate,
0:38.3	your area under the curve of insulin over the day will be higher.
0:42.3	But it doesn't make you insulin resistant. Hello and welcome to another episode of Sigma Nutrition Radio. My name is Danny Lenin,
1:16.3	your host as always. And although I say another episode, this one is not like the others in that
1:22.4	we have a very special episode of the podcast for you today. So we're at episode 210. And the special nature comes
1:31.0	from the fact that it's going to be an open discussion between two guests today. I'm
1:35.9	absolutely delighted and honored to be able to be joined in a few moments by Professor Tim Noakes
1:41.6	and Martin MacDonald. And we're going to discuss the general theme of carbohydrate intake, insulin resistance, and body fat regulation.
1:52.1	And so the reason why, I suppose, this has came about and why these particular two gentlemen, I think, are particularly well suited to get into this discussion, bring up a few
2:02.9	points, maybe knock around some points of contention, is that obviously right now there is
2:09.4	more interest than ever in low-carb, high-fat diets, particularly for body composition, for health,
2:19.9	and then also for people who have certain health conditions, and we're primarily going to focus on insulin resistance, pre-diabetes,
2:25.0	and diabetes today. But obviously, with that huge amount of attention that has came on the diet
2:32.0	over the past number of years and has been growing steadily
2:35.4	all the time.
2:37.1	I think there's plenty of questions out there.
