Self Control: A Limited Resource

Donating blood yesterday, going to bed late last night, a light breakfast, light lunch, and coming home lightheaded tonight: this is how I account for thinking that a dinner I knew added up to a lot of carbs (46) was a good idea. My resistance was lowered and not replenished. At least I didn't go far over my  daily 50-carb limit, and the meal was real food full of nutrients. But I know that big meals make me feel like a slug.

There's been research over the past few years about willpower being limited. Some clinical studies have looked at glucose's relationship to willpower, others have looked at performance on sequential tasks. Sandra Aamodt and Sam Wang write,

In one pioneering study, some people were asked to eat radishes while others received freshly baked chocolate chip cookies before trying to solve an impossible puzzle. The radish-eaters abandoned the puzzle in eight minutes on average, working less than half as long as people who got cookies or those who were excused from eating radishes. Similarly, people who were asked to circle every “e” on a page of text then showed less persistence in watching a video of an unchanging table and wall.
Other activities that deplete willpower include resisting food or drink, suppressing emotional responses, restraining aggressive or sexual impulses, taking exams and trying to impress someone. Task persistence is also reduced when people are stressed or tired from exertion or lack of sleep.(1)
Add hunger to the "tired from exertion" part, and it's no wonder eating less and exercising more doesn't work for weight loss. (Even if you keep at it, it doesn't work: see this.(2)) Before you rationalize eating cookies, keep in mind that your body only needs a teaspoon of blood glucose, and that it can make it out of protein. Eat some nuts or a low-carb brownie instead.

Limited self-control is a good reason to not allow yourself to get too hungry. Intermittent fasting may be all the rage--well and good if it works for you--but Dr. Atkins told his readers and patients to eat even if they just thought they were hungry(3) and for bingers to binge on protein(4), The New Atkins for a New You permits snacks(5), and Dr. John Briffa recommends having a snack of nuts or seeds if you're hungry between meals.(6) These doctors recommend quelling your hunger now so you don't go on a bender later.

This is why it's good to keep your home free of any food you shouldn't have. Sooner or later, we all get stressed out or run down--but if bad food isn't there, you can't eat it. Likewise, you need plenty of good foods on hand so you don't end up ordering Chinese (it's notorious for jacking up blood sugar too high).

There's a saying that good luck is often with the man who doesn't include it in his plans. The same thing is true for willpower.

Edited to add: It's the next morning, and I'm down a pound since yesterday. As I mentioned, I didn't go far over my 50g of carb per day limit. I just ate a really big meal, which makes me feel lousy.

An Objective Book about Other Childhood Vaccines

Today's decision by the CDC to add COVID shots to the schedule of childhood vaccines has some people concerned about the rest of the vaccines on the schedule. Contrary to fact-checker claims, adding COVID shots to the schedule means children will be required in about a dozen states to get a COVID shot to attend public school. Indiana isn't one of them--our childhood vaccination law doesn't mention the CDC and such a requirement could run afoul of our ban on COVID vaccine passports. But even freewheeling Indiana has some vaccine requirements and this kerfuffle has people wondering how safe those vaccines are.  There's a book called Vaccines: Truth, Lies and Controversy  by Peter C. Gotzsche, DrMedSci and co-founder of the Cochrane Collaboration, about the safety and efficacy of all those vaccines, including COVID and others. Cochrane was founded to "to organise medical research findings to facilitate evidence-based choices about health interventions involving healt

Battered Cod and my Eclipse Pictures of my Colander

If you miss battered cod on a low-carb, grain-free diet, here's a recipe that'll satisfy your craving. It's based on a Dr. Davis recipe. Battered cod and cole slaw Ingredients 1 pound cod fillets 2 eggs 2 tablespoons butter, melted 1/2 cup ground golden flaxseeds 1/2 cup grated cheddar cheese 1/2 teaspoon onion powder 1/2 teaspoon salt 1/4 teaspoon ground black pepper 1 teaspoon garlic powder Instructions Preheat the oven to 375°F. Line a rimmed baking sheet with parchment paper. Slice the cod into 1-1/2 to 2 inch pieces. In a small bowl, whisk the eggs and butter. Beat continuously--don't let the butter cook the eggs. In a shallow bowl, combine the flaxseeds, cheese, onion powder, garlic powder, salt, and pepper. Coat each piece of cod in the egg mixture and then roll in the in the flaxseed mixture. Place on the baking pan. Bake for 20 minutes, turning once. Eclipse Crescent Shadows Today was the total solar eclipse, and my house was in the "path of totality."

Eclipse Glasses, Probiotics for Heart, Muscle Recovery

Are your eclipse glasses fake? The total solar eclipse over North America is almost here, and Indianapolis is in the "path of totality," meaning the moon will completely block the sun here. A lot of people have gotten special glasses to safely look at the eclipse. But the American Astronomical Society says , "counterfeit and fake eclipse glasses are polluting the marketplace." Some of the counterfeit glasses appear to be safe, the society says, but others are fakes that are no more effective than sunglasses. One of the counterfeits they describe matches the glasses someone gave me. I don't know where she got them, and she's not someone I'd trust to perform adequate due diligence. I just got over an eye injury and I don't need another one--I'll try the pinhole method instead to see crescents during the eclipse if it's not too cloudy.

Diabetes Down, COVID Curiosities, New Glasses after Accident

Diabetes Down Despite Dietitians' Directions Last Sunday when I wrote about the grifters over at EatThis.com, which calls itself "Eat This, Not That," I was worked up enough to tweet to their medical expert board members if they stood by the site's article flogging sugary drinks and fast food for St. Patrick's Day. The site has over 1,300 articles, mostly puff pieces, on McDonald's and a news feed full of "the most important breaking news" on Doritos, burger joints and Chips Ahoy! I asked a dietitian who responded to me what exactly the "not that" part was in "Eat This, Not That." Important news about what you should eat! I was worked up until I remembered the saying, "You can't cheat an honest man." Meaning that this con, like a lot of others, requires some dishonesty on the part of the mark. Every Joe Six-Pack knows that cookies, chips and coffee-flavored milkshakes from Starbucks aren't health food. It takes s

Blog Lineup Change

Bye-bye, Fathead. I've enjoyed the blog, but can't endorse the high-fat, high-carb Perfect Health Diet that somehow makes so much sense to some otherwise bright people. An astrophysicist makes some rookie mistakes on a LC diet, misdiagnoses them, makes up "glucose deficiency," and creates a diet that's been shown in intervention studies to increase small LDL, which can lead to heart disease. A computer programmer believes in the diet and doesn't seem eager to refute it because, perhaps, scientists are freakin' liars and while he's good at spotting logical inconsistencies, lacks some intermediate knowledge of human biology. To Tom's credit, he says it's not the right diet for everyone, but given the truckload of food that has to be prepared and eaten, impracticality of following it while traveling (or even not traveling), and unsuitability for FODMAPs sufferers, diabetics and anyone prone to heart disease (i.e., much of the population), I'm
