In episode 17 of The Muscle Engineer Podcast I’m ridin’ solo, and look back on the last 2 episodes, giving what I considered to be the top 3 take-aways from each. Enjoy!

Topics discussed with time stamps:

1:06 A mini-rant on so called “evidence based” people dismissing anything that’s not published in a scientific journal

Episode #15 key lessons

3:28 #1 Don’t be afraid to try something out, even if it doesn’t have scientific backing and if it works for you, stick with it

6:25 #2 Something can be helpful short term, even if it’s unsustainable long term

9:29 #3 The value of synchronizing your food intake with your ancestry, the season we’re in and daylight hours

Episode #16 key lessons

14:10 #1 Insulin sensitivity is only good up to a point and increasing systemic IS with GDA’s might not be the best idea

16:55 #2 Choosing nutrient dense fat sources and having higher fat rest days

21:18 #3 The importance of sleep for improving insulin sensitivity and your overall health

When Adel, at that time still a physics student in his early twenties, became really interested in resistance training, nutrition and supplementation, there were few unbiased evidence-based sources with information on how to train, eat and supplement on the Internet. So what do you do if no one offers the non-sponsored, impartial, science-based content you'd like to read? Well, Adel decided to create this educative and science-based content himself... And that’s how his blog, SuppVersity (Supplement + University) was born.

The idea to review and communicate the latest results from nutrition, supplementation and exercise science is still at the heart of everything Adel does with his blog, the corresponding Facebook Page, during podcast interviews and in his function as a reviewer for's Research Digest.

Topics discussed with time stamps:

3:12 Adel’s background and current interests / projects

5:16 Insulin sensitivity - what is it and how can be measured?

8:28 Is daily blood glucose monitoring a valuable tool for dedicated lifters?

15:03 What are the symptoms of hypo- or hyperglycemia?

17:11 Is the inability to go for a semi-extended period of time without food a sign of poor metabolic flexibility?

22:01 The impact of visceral body fat on insulin sensitivity and health

27:45 How can we tell the difference between visceral and “regular”, subcutaneous body fat?

34:00 What are the lifestyle factors that can impact insulin sensitivity - chronic stress, lack of sleep, poor gut health (IBS, SIBO) etc

39:20 High carb, low fat massing – does Adel think it’s a good idea and what should the minimum recommended intake of fat per day be?

48:48 Should fasting periods be incorporated in order to maintain metabolic flexibility on a super high carb diet?

53:46 Glucose disposal agents (berberine; R-ALA, Acetyl-L-Carnitine) – what is their role and are they worth taking for a healthy, active individual?

59:15 Metformin as not only a GDA, but anti-aging “miracle drug” and potential safety concerns

1:02:02 Taurine supplementation and it’s benefits for performance, blood sugar regulation, hearth, gut and brain health

1:13:55 Adel’s definition of success

In episode 15 of The Muscle Engineer Podcast I’m joined by legendary Norwegian coach and educator Børge Fagerli to discuss his recent Carnivore diet experiment and a variety of related nutritional concepts.

Topics discussed with time stamps:

3:10 What made Børge decide to try this diet and was there a particular scientific reasoning behind this approach when the vast majority of nutrition points in a pretty much opposite direction - plant based diet with plenty of fruits and vegetables are what people in the blue zones seem to mostly eat

14:40 What meats did Børge eat? Did he consume any organ meats or eggs? Did he take any supplements with this diet to counterbalance the lack of certain micronutrients and minerals, and was he worried about potential overdosing of iron by consuming large amounts of red meat?

20:46 How long was the adaptation period to this diet, and how were satiety, performance and energy levels throughout the day and what effects did this diet have on his body composition?

24:18 What does he think the inflammation he suffered from before trying this diet was due to (genetics, eating foods that weren’t agreeing with his body)?

28:45 Is he worried that this diet basically starves the gut bacteria, which might be helpful in cases of dysbiosis, but also starves the good bacteria, probably making an individual less tolerant to plant based foods over time? And what does he think about the recommended 10-15 g of fiber / 1000 kcal?

36:10 What were the results of Børge’s blood tests and a discussion around cholesterol levels and their significance for health

42:25 The goals and durations a carnivore diet would be most suitable for

48:24 How would a zero carb, carnivore diet compare to a “regular” high protein diet that also includes some other protein sources and maybe some fruit here and there?

51:16 After finishing the experiment, how should we start reintroducing other foods, particularly carbohydrates?

54:37 Børge’s updated views on timing your carb and overall food intake during the day for health and body composition

58:22 How should we think of seasonal (circannual) rhythms that dictate what we should eat throughout the year and how should we adapt our diet according to that (food selection, overall energy intake and goals). Should we bulk during the summer and cut during the winter?

1:09:22 Does Børge prefer organic produce and what does he think about the sustainability aspect of a long term carnivore diet?

1:14:29 Where can you find Børge online

1:15:15 What is Børge’s definition of success?

Episode 2 of The Muscle Engineer Podcast, in which I’m joined by Triage Method’s co-founder Gary McGowan aka SkinnyGaz to talk about his personal fat loss phase, customizing the approach for the individual, mindset “hacks”, refeeds, taking responsability for your goals and much, much more.

We also get into some of my personal experiences and challenges with fat loss that I’m sure many can relate to.
