Sugar Isn't the Problem, It's This | Diary of a CEO's "Sugar Doctor" Debunked

from OB Health Podcast · host Ob_health

Dr David Unwin went on The Diary of a CEO and called sugar the toxic ingredient silently filling your liver with fat. Then he showed a chart where white rice and potatoes scored MORE "sugar" than a chocolate bar. As a fitness coach who's worked with over 1,000 clients, I had to break this one down.Here's the problem with the teaspoon-of-sugar system: it ignores satiety, fiber, micronutrients, and the actual driver of fat gain, which is eating more calories than you can stay full on. Demonize the potato and, by that exact logic, you should eat the Snickers instead. I agree with a LOT of what Dr Unwin says about doctors over-prescribing, lifestyle, and identity. But the central sugar example falls apart, and I show you exactly why.CHAPTERS0:00 "Potatoes have more sugar than a Snickers?!"1:21 Where I actually agree with Dr Unwin3:05 Why "eat less, move more" is broken advice5:19 There's no such thing as an "obesity gene"6:15 Identity + knowledge: what really decides your weight7:58 Why a calorie deficit is king (the Twinkie diet)11:16 The GLP-1 client who regained it all, and the fix14:30 "Is pizza healthy?"
