Calorie counter strike

Satiety, calories and recommended dietary guidelines.

Have you eaten? Are you still hungry? Feeling satiated is often not about hitting the right calories per day, but about eating the right kinds of nutrient-dense foods.

The term calorie is derived from the Latin word, calor ‘heat’ and was originally a term used as early as the 1820s to explain a unit of heat. When have we been calorie conscious? 1908 apparently, but it was a Californian physician and newspaper columnist Dr. Lulu Hunt Peters who popularised dieting using the concept, “don’t eat food, eat calories”. Watching what she ate and capping it to 1200 calories per day, her weight loss resulted in one of the first books on dieting titled, ‘Diet and Health: With Key to the Calories’ (1918)1. Shortly after, Dr. Peters was posted to the Balkans and witnessed life there as an American Red Crosser in WW1. She returned to the US three years later and was so surprised that her book had been selling so well that it became a hit.

Dr. Chris Barclay, a GP and author of ‘Beating Diabetes the Low-Carb way’ (2020) shared that in the last 20 years in the UK, the number of people with Type-2 Diabetes had risen from 1.4 to almost 5 million2. Dr. Peters’ successful diet, he theorises, may not have been about the calories after all, but about the fact that her meal plans were low in carbohydrates. She ate plenty of salad, vegetables (mostly raw), fruit, meat and fish, the occasional piece of bread and a few pretzels. There was no pasta, pizza, cake, biscuits or rice, no fruit juices, nor smoothies. Is this an example perhaps of mistaken assumptions and incomplete knowledge, he queries.

Swing back to kitchens of today, a promotion in a Hello Fresh meal kit website promises this, “Our carb smart recipes lower the amount of carbohydrates per serving by using wholesome ingredients like cauliflower, zucchini and avocado in place of high carb foods like rice and bread. And our calorie smart recipes keep each serving under 650 calories while packing in lots of nutrients so you feel super satisfied after every meal”.

You may wonder then if the hashtag #lowcarb is trending… Absolutely! Instagram itself has 27.9million posts with the ‘reducing’ hashtags #lowcarb as compared to 7.1m #diabetes, 75.9m #diet, 82.2m #weightloss yet it can’t compare with the ‘eating’ 284m #foodporn, 122m #vegan.

AFT Interviews: Dr. Pran Yoganathan Gastroenterologist and passionate educator uses IG memes to drive understanding on satiety

Gastroenterologist and hepatologist based in Sydney, Dr. Pran Yoganathan is an extremely passionate educator, a Mathematician-turned doctor who aims to empower his patients with data that can help them on a journey of self-healing using the philosophy of “let food be thy medicine”.

Dr. Pran who has innovatively harnessed creative technology and 14,400 followers on Instagram @dr_pran_yoganathan, stresses that his educational memes are not medical advice or recommendations, simply his opinions — and rather strong science-backed opinions they are too!

In the podcast interview, Dr. Pran speaks about his diet of choice, which comprises predominantly of grass-fed steak and eggs and why that has raised eyebrows and temperatures not just in the oven, but in conversation with peers as well. We ask him about butyrate and got him all fired up and excited! Now, are WE ready to absorb the fact that we’re meant to burn fat for energy and not glycogen? Let’s save that for perhaps another conversation. 

Joining co-hosts Jasmine Low and Nikki Yeo in this same episode are Dr. Desmond Menon, medical lab scientist featured in Ep. 2 Do Our Genes Predispose us to Diseases of our Parents and Malaysia’s “biggest” stand-up comedian Papi Zak who’s in training to be a wrestler.

Together, we pose our numerous curious questions to Dr. Pran and have a content-packed conversation that’s science-based yet entertaining and revealing at the same time! Dr. Pran’s message is to “eat a diet that is not rubbish, move your body”, and he shares science in between some of his Instagram posts.

We ask him why he got into gastroenterology, his inspiration behind the Hippocrates’ philosophy “let food be thy medicine” and his personal dietary habits.

On the table, we discuss hunter gatherer societies in our modern world where Dr. Pran shares about the Hazda ethnic group from Tanzania and how they forage for food today.

Dr. Pran sheds some light on high fibre diets – a push by the standard Western Diet and how excess fibre can slow down gut motility, cause reflux and bloating and fundamentally IBS.

“If you’re going to deal with fibre, you need the machinery. That is why you see our primate cousins, like the chimps and gorillas tend to have a thick hind gut, a very big belly, that’s not visceral fat, it’s simply machinery to deal with rough fibrous tissue. That’s not my theory, that is a scientific fact and it’s called the expensive tissue hypothesis. It’s what makes us special in terms of our species; our brains grew in response to a shrinking gut.

Incidentally, on a side track, if you’re interested to deep dive into the Expensitve Tissue Hypothesis by American paleoanthropologist and professor emeritus of the University College London Leslie Crum Aiello – click here. She co-authored the textbook, “An Introduction to Human Evolutionary Anatomy”, which uses the fossil record to predict the ways early hominids moved, ate, and looked.
