Based on the recommendation of a friend who had once described his waistline as “changing more often than Britney Spears’s (?) bra size”, I read Jasun Fung’s The Obesity Code over the last couple of days. The book is stellar.
Here are my highlights from the book.
Anyway, fitness and nutrition is something I’ve been struggling with for a very long time in life now. I used to believe that I have my health numbers (primarily triglycerides) under control because of regular lifting of heavy weights, but a recent blood test called that assumption to question. Having got what I now think is bad advice about what to eat and what not to eat, getting better advice on food is something I’ve been fairly receptive to. And the book does a great job of it.
The basic idea is – your body weight is controlled by hormones. How much you eat and how much you exercise doesn’t really matter. Calorie counting just doesn’t work. Your body has a “natural weight”, and if you are above that the body will try to adjust it lower, and vice versa. And this “natural weight” is guided by the hormones, especially insulin. The higher the level of insulin in your blood, the more your “natural weight” will be.
So the idea is to keep the level of insulin in your blood low. The author builds up a stellar case with some rigorous presentation of research. There is NO RELATIONSHIP between the fat that you eat and risk of heart attacks. A high carb low fat diet will make you fat.
And what I liked about the book is the structuring – the first 220 pages is all about presenting the research on various topics, and not really “giving away” what you should or should not eat. And then in the last 20 pages, he puts it all together, with a broad plan on what is good to eat and what is not.
In any case, I’m not going to reproduce the book here. You can go read it (it’s very very well written), or just read my highlights. The reason I started writing this post is to document my learnings from the book. I think I’d already internalised a lot of it, but some of it is new. This is how I plan to change my diet going forward:
- Sometimes in recent times I’ve noticed this “heady feeling” upon eating certain foods. I used to think it’s due to eating too much sweet. Now, after reading, I think it’s the feeling of an insulin spike in my head. I’m not going to have any fruit juices. Fruits need to be eaten whole
- I’ve largely eschewed added sugars for a while now (sometimes on and off). This will continue.
- Artificial sweeteners also cause a spike in insulin. I didn’t know this. So no more coke zero. No more Muscle Blaze Whey Energy powder as well (I now need to find a whey powder that doesn’t contain any sweet or any sweetener). No energy bars. No “no added sugar” biscuits.
- This is maybe the most important concept in the book – NO SNACKING. Eat exactly two or three times a day (I used to eat two a day, but nowadays I go to the gym in the mornings, so breakfast is necessary). Eat as much as you want at each meal, but don’t eat in between meals. The body needs lots of periods of time when insulin levels go low – so it doesn’t adjust to a higher natural level of insulin, which means a higher natural weight.
- Dairy products have a high “insulin index” (produce lots of insulin once eaten), but also have high satiety – they keep you full for a very long time after eating. After my last cholesterol test, after a fight with the wife, I largely gave up on cheeses. I’m reversing that now. I love cheese, and it’s good for me. Calorie counting just doesn’t work (the book does a great job of explaining this).
- Not doing keto. It’s unsustainable. And I love my fruits too much. Oh, and I need to eat my fruits along with my meals. Not as “snacks”
- Processed carbohydrates are not good. So no more bread for me. I need to figure out if fried eggs + milk will be enough for breakfast. Or find a decent substitute.
- I also need to figure out how good or bad basmati rice is. Definitely makes me feel better than sona masuri (which we used to eat before). Need to figure out if this feeling is justified.
- Peanuts are good. Peanut butter is good. Other nuts are good as well. But need to eat them for breakfast. Not as a snack.
The hardest part for me, with this new regimen I plan to start, is “no snack”. I’d gotten so used to snacking that I think I eat far less than necessary during my main meals. And that results in a vicious cycle. I’ve attempted to start breaking out of that by supplementing my chapati-paneer curry with some curd rice tonight.
So far I’ve been feeling great. Let’s see how this goes.
