This is me after Sunday’s 100 km ride with Moment Cycle Sports. Yes, I wear jeans, a t-shirt, and a backpack, and ride my fixie with the roadie clubs around town. I weigh 77 kg now, and my ultimate goal is around 70 kg. I was a wreck 16 months ago @ 105 kg.
Perpetual thanks to Dr. William Davis for establishing the six bagel stack as a dietary icon. When I think of Wheat Belly, it’ll usually put me in the mood to pick up half a dozen bagels. They have a special at Einstein Brothers, where six bagels plus a half-pint of spread costs $9 USD. The bagels totaled to about 630g, so it’s a reasonable price.
I was really hungry after back-to-back spin classes this morning, and I quickly finished four of the bagels. They were just-baked warm and delicious! I’ll save the last two for after dinner, which will probably be Taiwanese noodle soup again.
Yes, if I eat a stack of bagels everyday, I’ll lose weight. It’s not magic, it’s just a low-fat diet.
(If you really want to do the math: I burned about 1600 calories in spin today. Maybe 60% of that was from fat, so I burned about 100g of fat from adipose stores. I’m pretty sure my post-workout carb meal was used to replenish glycogen stores, and almost no fat was created by DNL. But, even if 5% of the bagel carbs were converted to fat, that’d be (5%)(4/6)(630g bagel)(2.75 kcal/g bagel)(g carb / 4 kcal) = 14 of fat. No problem. I’ll burn 14g of fat sometime in the 6-8 hours before dinner.)
Lately I’ve been eating about a 1/2 box of cereal a day, along with about a pound of bread, and a bunch of tortillas. Before I learned about de novo lipogenesis, and how excess carbs are not easily turned into fat, I thought this would be a recipe for instant weight gain. I didn’t know it was just the dietary fat that got stored in our adipose tissue, while the carbs are just stored as glycogen, or burned off.
Plus, I didn’t know that these “carbs” contained all the protein I needed. I probably would have added some meat, afraid of being protein deficient. Of course, that meat just contains a bunch of fat that my body would store, and I’d get fat. Then I’d probably blame the “carbs”, because that’s been the popular message for the last 15 years.
Nowadays, I think of the bread and cereal as “carbs and protein” that’s fat-free. Basically, most starches contain about 12% protein, by calories. So, if I eat about 3000 calories of bread, etc., it’ll contain (3000 kcal)(12%)(g protein/4 kcal) = 90g of protein. That’s way more than I need, which is at most (1.2 g protein / kg of body weight)(77 kg) = 92g.
The beauty of eating almost no fat is that I don’t bother even thinking about calories anymore, let alone count them. I just eat the cereal and bread until I’m full. Then I probably eat some more cereal out of the box while watching tv on the sofa. No problem. My body will top off its glycogen stores, then burn off the rest.
I didn’t ride the bike on Monday or Tuesday, so my glycogen stores were completely maxed out for tonight. When I started my ride, my legs felt very strong. (Normally, they’re tired from day-after-day riding.) I rode my usual 5th Ave hill reps, and I PR’ed the 5th Ave Cedar to Laurel segment, taking 3rd overall with a 1:57 (out of 770 riders).
The biggest problem with constantly eating carbs is that it probably forfeits some opportunities to burn fat. I might return to eating more vegetables and lower calorie density starches like potatoes. But for the last few weeks, I’ve pounded down unlimited refined carbs (bread, noodles, and tortillas), and still lost weight. That’s a nice lesson to learn.
When I get on the road at lunchtime, I’ll often pick up a loaf of bread to eat while I drive. I tried this brioche from Bread and Cie for the first time, expecting it to be really good. But it was drier than I thought it would be, as I expected the egg and sugar to make it really delicious. They must really try to make this healthy, since the nutritional info claims only 25g of fat for the whole loaf.
Anyways, I ate half the loaf driving to my destination, and the rest on the way back home that night. I also ate more bread, tortillas, and noodles. I always try to keep the fat intake below 50g/day, which means you have to check all labels and know all the ingredients in your food. Luckily, you don’t have to count calories, nor worry about whole grains, or that “carbs make you fat”. Who’s afraid of a loaf of bread?
Gary Taubes is so obsessed that “carbs make us fat”, that he thinks we could (should) eat unlimited fat, as long as we don’t eat any carbs. Who the ^#%$ wants to do that? Sure, I like bacon and eggs, but I’d rather eat sensibly than follow some tortuous ketogenic diet that doesn’t work (see below).
I prefer to eat low-fat (< 10% of calories), knowing that I can eat unlimited carbs, exercise moderately, and not risk gaining fat. This is because the body can't readily turn carbs into fat (de novo lipogensis is slow). However, any excess dietary fat will be quickly stored as body fat.
Gary Taubes takes the same understanding of the body’s mechanisms (that we preferentially burn dietary carbs and store excess dietary fat), but reaches a different conclusion. He reasons that if you don’t eat any carbs, then you can’t store any fat. WTF?! How do you make that conclusion? This logical error is called the fallacy of the inverse (If A, then B. Therefore, if not A, then not B. Not!) Here, A = “overeating carbs AND fat”, and B = “we become obese”. So “overeating fat BUT eating no carbs” is not A, therefore not B, and we don’t become obese. Not!
Some people realise this can’t really be true, and aren’t surprised when they hear about people (like Jimmy Moore) gaining weight on a ketogenic diet (< 30g/day carbs). That's exactly what a caller to Sean Croxton's Underground Wellness podcast asked (could you over-eat fat, without any carbs, and not gain weight?). Here’s Gary Taubes’ response (starts at 4:00):
… but I do not believe you can get fatter [no matter how much fat you eat, when you eat no carbs], and for most people, probably some huge proportion, 80% – 90%, if you’re not eating carbs, your’re going to lose weight, you’re not going to gain it.
So to me, its the carbohydrates that literally make you fat. You will store the fat that you eat. See, what happens when you eat the carbs and your insulin levels go up, you store the fat, the dietary fat, while you burn the carbs. And if your insulin levels stay up, you never let that dietary fat that you stored out of your fat tissue. So the carbs are still the problem, even though the fat is being stored first.
So he understands the well-known “fat-sparing” effect of eating carbs. Carbs are preferentially burned while the fat is stored. So most reasonable people eat low fat to minimize its storage. (Our bodies were made to store fat. It’s a great survival feature.) But Gary Taubes thinks we can trick the body into not storing excess dietary fat, by not eating any carbs. Good luck with that.
Then he goes on:
And because of that, we’ve been told, “Well, since we’re storing the fat and burning the carbs, if you don’t eat the fat, or if we eat less of it, we’ll store less of it.” But the carbs are controlling how the fat tissue is holding on to the fat, and whether it’s releasing it to be burned later.
So the carbs are basically what’s regulating the insulin and the insulin is regulating the fat and the dietary fat is only a problem if you’re eating a high carb diet.
He’s saying that low-fat diets don’t work, because carbs never let the fat out of the adipose tissue. But, there are plenty of times where the body burns fat, like in between meals, during moderate exercise, while you’re sleeping, etc. Sure, if you constantly keep eating, you won’t access your fat stores, but in most normal people, adipose tissue is metabolically active. Excess fat goes in when eaten, and comes out as needed. (Hey, what would happen if you didn’t eat any excess dietary fat?)
Argh. You know, if you like bacon and eggs, then eat them. If you want to eat ketogenic, then good for you. And if you want to believe that carbs make you fat, no matter what the science says, then hopefully the low-carb approach works for you. But if you go around arguing that there’s a metabolic advantage to eating no carbs, please try listening to reason occasionally.
I don’t think anyone out there really believes that low-fat noodle soup will make you fat. On the other hand, I’m sure everyone knows that frying them up and adding a bunch of fatty meat and oil-soaked vegetables makes a perfect recipe for weight gain. So, I avoid the restaurant dishes like Chow Fun and Chow Mein, and just make my own soups which are all-noodle, and no fat.
These 3 lb bag of noodles are a couple dollars each, and will make about 9 meals each. I’ve learned to cook the noodles for 3 minutes, then drain them before adding them to the soup broth containing mushrooms, green onions, carrots, cilantro, broccoli, and bok choy.
I don’t need to understand about de novo lipogenesis to know these noodle soups won’t make me fat. They’re satisfying meals for cold winter weather, and if I’m still hungry, I’ll eat some more bread, beans, or tortillas.
Even though I cycled over 300 km last week, the Thanksgiving feasts of turkey, cookies, cake, pie, and chocolates ended up winning on the scale this morning. I never restrict my calories, nor when or how much I eat, so I have to stick to the low-fat whole foods to lose weight. I think I would have done fine with all the eating out, and the higher fat “real” foods, but it was all the desserts that did the damage. Maybe for Christmas, I’ll eat the roast beef, but none of the desserts.
I’m back on the high-carb, low-fat eating plan, and I’ll probably see improvements on the scale over the next few days. I’m pretty familiar with how my body weight reacts on my diet, so I know it’ll continue back down.
I was afraid of stepping on the scale this morning, but overall, the slight uptick is no big deal. It could have been a lot worse, and I again learned the lesson that “you can’t outrun your fork”.
Okay, with all the relatives in town, and the fun of eating out, I’m not toting around a loaf of bread, and insisting on my boring low-fat diet. So it’s two slices of pizza and a “salad” (the good kind with the tossed-in fat and meat), with frozen yogurt for dessert. This is the only time I’ll watch the quantity of food I’m eating (like normal people do, I guess).
I rode 50km this morning, with some good hill efforts, so I’m probably keeping a little ahead of my fork. I’ll still lose weight eating this, even though I have to resort to the dreaded “portion control” mindfulness. Think of it as a LCHF diet with real healthy fats, plus some plain bread.
Update: Ate more off-plan junk after dinner, including a bunch of cookies, more pie, and chocolates. I’ll hope to burn off the calories on the Sunday morning ride, but from experience, I know “you can’t outrun your fork”.
Golden City is the best Chinese restaurant ever, because the food is great, the service is actually good, and the place is clean, bright, cheerful, and quiet. There might be a few other places like this, but I’ve never seen them. So instead of dreading a family outing, I’m actually pretty happy to have dinner there.
I only had a 600g loaf of bread today, so I’m pretty hungry. I hammered some hills this morning, fueled by Thanksgiving dinner and pumpkin pie, and I PR’ed the 5th Ave Hill Sprint from Date to Laurel, placing an overall 4th @ 2:00 (out of 2,900 total attempts). I’ve been monitoring my progression on this hill, because on my fixie, my times are a direct function of my weight. I’ll still probably lose another 5-7 kg, so I expect to improve by another 10 seconds or so.
Anyway, my family is in town for Thanksgiving, and four of us are pretty involved (obsessed) with health and fitness, so the dinner conversation always includes a debate over carbs. I give them the vegan argument that you get everything you need from bread, tortillas, beans, rice, and vegetables. Everyone else worries about protein, and thinks you have to get it from meat. Plus, they’re convinced that bread makes you fat, and I only get away eating a pound a day because I bike a lot. We have the same conversation every meal (because I bring it up), and no one changes their mind 🙂
I used to think that the low-fat vegan crowd were diet-Nazis, who couldn’t even begrudge me a reasonable amount of fat or meat in my diet. They seemed particularly humourless, singularly bent on taking all the fun out of food. Well, I finally “get it” now, and not because of their constant beratings and lectures.
I started eating a very low fat (~10% of calories) diet, because I learned a few simple things. First, the body doesn’t easily turn carbohydrates into fat (de novo lipogenesis in humans is slow and basically insignificant). Secondly, the body simply and reliably burns fat from adipose tissue during low to moderate exercise . So, I put 2+2 together, and eat only “carbs” (breads, tortillas, noodles, etc.) and avoid all fats (oils, meats, etc.). I eat whenever I’m hungry, and my exercise is a one-way fat burn (can’t come back, even if I eat a loaf of bread after a workout).
I ate most of this challah loaf after a 100km ride on Saturday. It’s made with eggs, so it has more fat than I wanted, but 50g of fat after a hard workout won’t kill you. Before the ride, I ate a nice fresh bagel and drank 350ml of orange juice. For dinner, I had a rice and bean burrito. For dessert I ate about 300g (most of the box) of Shredded Wheat cereal with blueberries, bananas, and almond milk. I ate a few corn tortillas for good measure.
It’s a great relief knowing that unlimited carbs (but no fat) won’t make you fat, nor interfere with your fat-loss workouts. I just eat till I’m full, and consider the food as re-fueling my glycogen stores. At any rate, I know that even refined carbohydrates aren’t easily turned into significant amounts of fat, so I’ll eat yummy breads like challah. A big post-workout carb meal doesn’t “nullify” my efforts, since the fat was burned during the exercise, and carbs aren’t turned into fat. (Sure, calorie restriction would probably work to burn even more fat, but why would I bother?)
So, I’ll continue with this low-fat diet (<10% of calories) and we’ll compare the weightloss rate on my progress chart. I’m never hungry, and even occasionally overeat a little too much bread and/or tortillas. But I’m progressing towards my 70 – 75 kg goal (I weighed in at 77.4 kg this morning) at a noticeable pace. It’s pretty rewarding, and worth giving up the fat for. Don’t worry, I’ll eat reasonable amounts of meat after I make my weight goal.
