A Limit to Counting Calories

I am on record as stating that calories count. However, I am about to revise that opinion slightly. I have been counting calories and measuring my macronutrient ratios using the free software at livestrong.com. Since I began counting calories in August, I have lost nine additional pounds, after a mild stall. But I have discovered one thing that gives me pause in counting calories: I may still be eating too much.

It is all psychological. I have been rigorously tracking every calorie I consumed, but recently I have noticed that at the end of the day, I often have several hundred calories left. Since I have the calories left, I have felt obligated to use them, even if I wasn't hungry. After all, livestrong.com tells me I should be losing two pounds per week based on my height, weight, and age. But I am not losing two pounds per week and it occurs to me this is because I am consuming too many calories, even when I am below the level stipulated by livestrong.com for a two pound weight loss per week. I think all of these months on a low carb diet have slowed my metabolism.

So I am trying something new this week: eating until I am full, but stopping when I am no longer hungry, even if I have hundreds of calories left. Yes, I will still track the calories but won't feel obligated to consume them. We'll see how this goes.

In the "Good News" category, I have not regained five pounds by switching to the Perfect Health Diet, even after increasing my daily carb intake to around 100 grams per day, mostly from rice, potatoes, and whole milk yogurt.

Lipid Profile

I got the results of my completely useless lipid profile today, and my doctor reacted exactly as I predicted (here and here). She applauded my weight loss, congratulated me on low triglycerides and an HDL number in the normal range, but was "very concerned" because my overall score was 197 and my LDL was 142, was 12 points above the upper end of the "normal" range. She wanted to put me on statin drugs, which I politely refused.

Since I suspected this would be the reaction, I brought the explanation of pattern A and pattern B LDL particles to her attention and pointed out that the LDL number was a calculated, not measured, value. I showed her the pages in The Art and Science of Low Carbohydrate Living by Jeff Volek and Stephen Phinney that discussed why LDL readings are often elevated in people following a low carb diet and explained how the calculation overestimates the LDL cholesterol particles. She did not know what to say.

People like Kurt Harris, M.D. question the whole utility of getting a lipid profile. What's the point? Saturated fats don't cause heart disease and statins don't do anything, so why bother spending money to get a number that is meaningless? I think I can see where Kurt Harris is coming from.

Liver and Onions

Yesterday marked a full week on the Perfect Health Diet, my new take on low carb living. Each day, I had been taking my multivitamin, eating three Brazil nuts, getting enough sun, etc., everything except... eating liver. But I committed to doing the Perfect Health Diet correctly, so, on the last day of the week, we made liver and onions.

And I lived to tell about it. Actually, it wasn't that bad. I followed Sally Fallon's suggestion of soaking the liver in lemon juice for "several hours" prior to cooking it, then cutting it into small pieces, as per the Nutty Kitchen suggestion. I cooked it outside on my Camp Chef stove in a cast iron skillet so as not to stink up my kitchen (we had visitors coming over after dinner).

Cooked this way, with lots of onions, butter and garlic, it was... tasty. And I discovered that my aversion to it was mostly psychological, probably leftover from my teenage years when I was a cook at Perkins Cake & Steak, where we cooked really smelly liver. I like pâté de foie gras, goose liver, and chicken liver pâté, so I wonder what my problem was with beef liver.

Why Taubes has Groupies

In a tweet today (Labor Day, September 5, 2012), Paul Jaminet commented:



I don't think this is hero worship at all. I think it is a visceral, positive response to his message, reinforced by successful weight loss. Let me explain.

DISCLAIMER: I have matured in my low carb way of eating and thinking. I have given up on several of Taubes' ideas, because they didn't jive with my experience. I believe calories count, that exercise matters, that there are safe carbs, and I am following the Perfect Health Diet version of low carb eating now. I believe that we have confused an obesity cure (cutting carbs) with an obesity cause (carbs are fattening). Just because cutting carbs can cure obesity does not mean that carbs cause obesity (thank you, Chris Kresser, for expressing this idea). I eat about 100 grams of carbohydrates per day, mostly from whole milk yogurt or safe starches such as rice and potatoes. I have also lost almost 60 pounds thanks to the low carb way of eating, and Gary Taubes introduced me to it, for which I am very grateful. Even though I no longer believe some of what he wrote, he had a powerful influence on my life, for the better.

Okay, now the explanation. I don't know if Paul Jaminet or Emily Deans or Beth Mazur have ever been obese or not, though I suspect they have not. Taubes' message rings true if you have struggled, unsuccessfully, with weight for a long time. I have struggled through thick and, sometimes, thin, for most of my life. I have been about 100 pounds overweight, lost that on Weight Watchers, regained it (very embarrassing), and despaired about ever being able to achieve a normal weight. I was about to give up, when a post on InstaPundit.com linked to Why We Get Fat. I downloaded the book from Audible.com, but didn't immediately get around to listening to it, until the 12th and 13th of February, 2011.

Taubes gave an explanation for obesity that didn't focus on me being a slothful glutton. He provided a rational that led me to believe my metabolism was broken, and that I had been lied to by the low fat, high carb establishment, including Weight Watchers. I clearly remember listening to this explanation with my jaw slack. It was something completely different than anything I had ever heard, and it put the blame on insulin rather than on my weak will and base desires. No wonder Weight Watchers failed! According to Taubes, I was starving at a cellular level! On Valentine's day, I started eating low carb and I lost 11 pounds in the first two weeks. Success! I had personal evidence that what Taubes said worked, and I was firm in the belief that I had been fat for reasons other than my weak will and abnormal appetite. Further, the low carb diet slayed my hunger demons and made it possible for me to go about the day, without obsessing on food, just as Taubes said. He had great credibility with me, and I bought and devoured Good Calories, Bad Calories and had several epiphanies reading that. Such as the whole Ancel Keys story on the demonization of saturated fat. I was hooked.

Only later did I realize that some of his ideas were not scientifically grounded, that he was a theorist, not an empiricist. I discovered alternative voices, such as Kurt Harris, Paul Jaminet, and Jenny Ruhl, all of whom viewed low carbing differently than Taubes. I have gradually changed my view of some of Taubes' ideas, but it took a long time for the halo effect to wear off. It still hasn't worn off completely, and I am grateful Taubes exposed the whole "fat is bad" line of reasoning and that he introduced me to the low carb way of eating.

To an obese person, Taubes' message resonates powerfully, even viscerally. When you experiment on what he said, you get immediate, substantial results. No wonder so many people think so highly of him.

Right or wrong, that is why he has a lot of followers and that is why he is such a big name in the low carb community.

10% Goal Reached--Again

The weight loss continues to happen, though much more slowly than at the beginning of my low carb way of eating. That said, today I hit another milestone. I lost 10% of my body weight--for the second time. I started out weighing 301.6, then some time in early May, I hit my first 10% goal by losing my first 30 pounds (271.6). Today when I weighed myself (I weigh in every Monday morning), I was at 242.6, down another 29 pounds and realized that some time in the last week or two, I hit my 10% goal again.

A lot has changed since Valentine's Day, 2011, when I embarked on this low carb way of eating. At first, I was losing weight very rapidly, but that has slowed in recent months, to about a pound per week. I have changed my approach to my low carb way of eating. First, after stalling, I started to count calories.  Then I doubled my carbs about a month ago but still stayed under 50 grams of carbohydrates per day.  About a week ago, I started the Perfect Health Diet, a low carb way of eating that permits "safe" starches, such as rice and potatoes. I don't eat a lot of these safe starches, just enough to provide my body with the glucose it needs to function, but that effectively means I have doubled my carb intake again, this time to around 100 grams of carbs per day.  I was afraid of gaining water weight by doing this, but that hasn't happened so far, and I am cautiously optimistic. This past week's weight loss came from the Perfect Health Diet version of my low carb eating experience.

Even though the weight loss has slowed, I am more committed than ever to this way of eating. My hunger is at bay thanks to the protein and fat I consume and the food I am able to eat is very delicious. It is a much more pleasant experience than Weight Watchers, even if the weight came off faster on Weight Watchers. This is sustainable and I feel like I will be able to eat this way for the rest of my life. That is the key to weight loss and weight maintenance.

Five Perfect Health Diet Days

Today is the fifth day on the Perfect Health Diet version of low carb. The good news: no five pound weight gain! I have been eating about 100 grams of carbohydrates per day for each of the past five days with no real negative effect on blood glucose levels, and no weight gain.

But there has been a positive effect on the blood sugar. The morning after consuming the first 100 grams of carbs, my fasting blood glucose reading was actually below 100. And it has stayed in the 95 to 105 range ever since. Normally, my fasting blood glucose reading is near 130, the only out of whack blood sugar reading.

So why has it normalized at a lower range? Perhaps because my liver is no longer converting protein to glucose over night. The theory behind the Perfect Health Diet is that your body needs glucose to function, so you might as well provide that glucose with "safe" carbs, rather than stress your liver by forcing it to produce glucose very inefficiently through a process called gluconeogenisis. I had concluded those high fasting blood glucose levels in the morning resulted from my liver converting protein to glucose while I slept.

On a positive note, there are now a lot more foods I can eat, when one allows potatoes, rice, sweet potatoes, tapioca, etc., back into the diet.

Nervous About Perfect Health Diet

I did it today. I started in earnest the Perfect Health Diet. And I am nervous about it. We potatoes with dinner tonight and I figure I consumed about 35 grams of carbs with my potatoes. I finished the day at about 85 grams of carbs, which, for me, is a lot. I haven't consumed that many carbs since before I started a low carb way of eating.

The Perfect Health Diet makes a lot of sense; it recommends getting 50 to 150 grams of carbs from "safe starches," such as rice, potatoes, yams, and taro. The logic: your body needs a certain amount of glucose to function, and if you go very low carb, you force your liver to produce the glucose from protein. Which is not necessarily healthy for your liver. So I get why "safe" carbs are necessary, but it is hard to change old habits. It's a bit like changing religions, really.

And I am a type II diabetic and I really have to watch the carbs I consume. So I checked my blood glucose levels after dinner and they were fine. Two hours after eating dinner, including the potatoes, it was 118. Ideally, two hours after a meal, it should be below 120 but at a bare minimum, be below 140. So I met that standard. Jenny Ruhl said in a recent podcast with Jimmy Moore that most type II diabetic men she knows can handle 75 to 100 grams of carbs per day, so I am hoping she is correct. If not, I will have to scale back.

Another issue making me nervous is I am likely to gain five pounds, almost over night, by replenishing glycogen stores. But I have to keep reminding myself that it is only a water gain. The theory is, one molecule of glycogen bonds with four molecules of water, and since we normally carry around a pound of glycogen, that means, gulp, one pound of glycogen and four pounds of water. It's all psychological. I know it is going to happen and I know it is water, but it still makes me nervous. Paul Jaminet says it may not happen, so I can at least hold out a little bit of hope.
