This Week's Links


Here are some more good reads that I came across this week. Enjoy!

Ross Enamait gave us a new article called The Endless Search imploring us to stick to the basics and never forget that it is the individual that determines the effectiveness of a training protocol (or by extension, nutrition plan), not the protocol itself.

I found this gem on Mark Sisson's site: The Carb Pyramid. Notice the base of greens, colorful, and cruciferous vegetables. That's lettuce, spinach, broccoli and califlower, peppers, onions, carrots, radishes, cucumbers, celery, and kale, collard, mustard, and turnip greens. And plenty more vegetables that fall in that category. Round out your carb intake with some sweet potatoes and fruit depending on your activity level and maybe add in a bit of rice here and there. As Mark shows, bread and sweets are relegated to the uppermost reaches of the pyramid and there's no danger in not consuming these items at all.

Robb and Nicky discussed breakfast. I chimed in with the first comment and my thoughts on breakfast.

Dr. Eades talked about Intermittent Fasting and Inflammation. The charts at the bottom show reductions in IL-6, CRP, and Homocysteine, all markers of inflammation.

Like green tea? Here are the 9 main types of green tea from Dr. Weil's website.

A Day of Vittles

I've talked several times about my IF protocol, so I thought I should give some examples of what a day of eating looks like for me. This is my menu from yesterday at about 6:30pm to today at about 6:30pm, when I started my next 24 hour fast. I'll start eating again tomorrow at 6:30pm.

Dinner

Last night, I broke the fast with a bowl of canteloupe and blackberries covered in ~1/2 can of coconut milk and some cinnamon.


I ate that and then made a salad of 1/2 head of red romaine lettuce, the last of a bunch of purslane, a small cucumber, a carrot, 2 hard-boiled eggs, and 1/4 of a raw onion, along with a few almonds. The dressing was 3 tbsp of olive oil and the juice of a lime with oregano, fresh basil, and fresh-ground pepper. I forgot to take a picture of the salad before I started chowing, so here is one after a bit of eating.


The salad was eaten while my chicken thighs (*gasp* with skin) were grilling. As the chicken was finishing cooking, I sauteed the other 3/4 of the onion and the leftovers of some green beans from Sunday in a skillet with a tbsp of palm oil and some crushed chili sauce. Put it all together and this is what you get (that's 3 chicken thighs).

Breakfast

This morning, I got up and had some watermelon (already half-eaten in the picture above) with the other half of the can of coconut milk and then made lunch while my breakfast cooked. For breakfast, I sauteed an onion in olive oil, then cracked 4 eggs and cooked them sunny side up with the last of the basil and some garlic added at the end. Along with that, I had a can of Beech Cliff sardines and a few slices of the cucumber that went in my lunch salad.

Lunch

For lunch at work today, I had a salad of 1/2 head of red romaine, a large cucumber (minus the breakfast slices), a carrot, 1 raw onion, 2 hard-boiled eggs, and 3 chicken thighs topped with 3 tbsp olive oil, 1.5 tbsp organic balsamic vinegar, oregano, basil, and pepper. Alongside that, there is a bowl of blackberries and strawberries with coconut.

Dinner Again

My last feeding today was a light dinner of 2 chicken thighs with some verde salsa and a pint of boiled Brussels sprouts with a touch of soy sauce and olive oil. I finished off the meal with some more watermelon.

The tally for 24 hours of eating is:
- 1 head of red romaine lettuce
- 2 carrots
- 2 cucumbers
- 3 onions
- A handful of green beans
- 4 bowls of fruit - blackberries, canteloupe, strawberries, and watermelon
- A bit of purslane
- 1 pint of Brussels sprouts
- Various herbs/spices - fresh and dried basil, dried oregano, cinnamon, garlic, and pepper
- 8 eggs
- 8 chicken thighs (~2 lbs counting bones)
- 1 can of coconut milk and some shredded coconut
- 1 can of sardines
- Olive oil and balsamic vinegar dressing
- Olive oil and lime juice dressing
- A few almonds

As they say, you have to watch those low-carb diets. They don't allow you to eat any vegetables at all. Actually I'm not sure that what I'm eating would really qualify as low-carb due to all the fruit, but it's late summer and I'm taking advantage of nature's bounty. I'm sure there are people out there that will look at this and say "That's not healthy! Look at all that fat and protein. And where are the grains? You have to have some whole grains. Where do you think you get fiber? Ohmigawd, coconut and palm oil....augh! Saturated fats! Chicken thighs? Dark meat is bad for you and you shouldn't eat the skin because that's where the fat is [It's also where the vitamins are]." And to those people I say "Your indoctrination is nearly complete. Keep watching the news for your nutrition information."

Of course the reality is that in 24 hours I probably consumed more vegetables and fruits than 90% of vegetarians and 99% of the general American public. The diversity of produce in one day of eating is likely higher than most people eat in a month. This diet is replete with vitamins, minerals, proper fats, plenty of protein, and a good dose of fiber.

Anybody else want to offer up a run-down of their day's eating?

My New Fasting Regimen

I wrote a month ago about my ad-lib eating/fasting regimen. Soon after that post, I changed things up. With my lack of exercise due to shoulder surgery, I cut down on my food intake since I wasn't supporting any level of exercise. Between not exercising and not eating as much, I quickly shed 12 pounds, much of which was hard-earned muscle put on from Dec-May. One problem was that I went to eating for only about 4 hours a day and was having trouble taking in enough calories to maintain my weight without resorting to sub-optimal foods, which I pretty much refuse to do (outside of an occasional treat). So I'm now doing a 24-on/24-off regimen. I still eat everyday, but the timing of my meals is different. I have been going about 6:30pm to 6:30pm, either fasting or eating. So today I won't eat until 6:30 and what I eat will be a normal-sized meal rather than a gorge-fest of trying to ram in a day's worth of calories. Tomorrow I will have breakfast, lunch, and possibly another small meal before 6:30 hits and I shut down the eating to start fasting until 6:30 Wednesday.

I've been doing this for a couple weeks now and thus far I like it. The main benefit over my previous setup is that I don't have to gorge myself at my evening meal in an attempt to take in enough food. A lowish-carb, moderate protein, high fat diet makes it hard to really go hog wild eating because protein and fat are so satiating. The main drawback is that on Tuesdays and Thursdays ("eat" days), I have to get up early, make breakfast and lunch, and carry lunch to work with me. But it's a small price to pay to not waste away. Now that I'm back to working out with regularity (discharged from physical therapy!!), food intake is going to become more important to support recovery and fuel my activity level. I haven't really noticed any benefits in terms of performance (possibly since I haven't been working out as intensely) or mental clarity, but it is nice being able to eat without stuffing myself and knowing that I can get in plenty of high-quality calories to support my bodyweight and activity level.

Anyone else have any experience with Intermittent Fasting? I love IF, as evidenced by my two glowing posts about it. I'll give you a run-down of 24 Hours of Eating here soon.

Hayflick Limit, Intermittent Fasting, and Life Extension

There was an interesting discussion of using Intermittent Fasting for life extension at the Performance Menu a few weeks ago. Robb Wolf, in all his genius, mentioned something I'd never heard of before known as the Hayflick Limit. This principle is a conondrum for those hoping for to extend life much beyond normal human limits.

Here's a quote from the Wikipedia article that sums it up nicely:

The limit to the number of times a cell divides has been noted in all human cell types that have been fully differentiated, as well as in other organisms. It varies from cell type to cell type, and more significantly from organism type to organism type. The human limit is around 52.


I find this kind of biochemical geekiness absolutely fascinating.

I recently talked about Intermittent Fasting and the benefits that I have derived from it. In that post, I mentioned CRON (or CRAN) and how its practitioners hope to retard the aging process and extend their lives. My reasoning for doing IF is less about quantity of life and more about quality of life. If I had a choice of leading a full and active life and dying at 75 or leading the inactive life that CRONies are forced to live due to their limited caloric intake but having an extra 10 years, I would go with dying at 75 and living life to the fullest (my opinion may change as I near that age though). I find that IF allows me to find the perfect Triple Point (another gem from Robb) of Performance, Health, and Longevity. I am able to perform optimally in the gym, my health is impeccible, and I would surmise that, barring some freak accident, my longevity will be above average. I don't expect to extend my life to some beyond-human-limits age. I feel that I am merely setting myself up to live past the average life expectancy and still be a functioning member of society rather than one of the typical worn-down 80 year olds we see.

Dr. Garrett Smith mentioned on a Crossfit Live session (episode 12) many moons ago that if you ask someone if they want to live to 95, they nearly invariably say no (it's in that mp3 somewhere). That's because what we commonly see is people that live a good life until 60 or 65, then a life of poor nutrition, stress, poor sleep, and no exercise catches up with them and they spend the next 20 years dying. But there are plenty of vibrant, energetic, and strong septuagenarians and beyond. These folks don't exhibit that typical wasting away, medicated lifestyle characteristic of aging. That is what I'm shooting for - 85+ years of life and then a quick, natural death rather than 65 years of life and a long, drawn-out death that takes 20 years and saps every bit of life from my soul; alive, but not truly alive. In the natural world, death is a quick process and as Dr. Smith notes, after an accident or injury, the healthy tend to either get better or die rather than languishing in an ever-increasing cycle of loss of independence, function, and health. "Get better or die," as cold as it sounds, is the way nature works.

Ad Lib Eating and Intermittent Fasting

"Eat 5 smaller meals per day to maintain energy levels." That's pretty common knowledge in the nutrition world, is it not? I reject this line of thought. I eat only as many times as I need to eat each day. My day consists of somewhere between 1 and 3 meals, generally two large meals with about 18-20 hours of fasting ("compressed eating window"). I don't really see the point in forcing myself to eat 5 or 6 times each day. There are several reasons I eat this way.

First, the human body isn't designed for constant feasting. A constant titration of calories and insulin is not a natural state for humans, who would've fasted (or eaten lightly) during the day's hunting and gathering and then feasted at night. Some days there would be little food (unsuccessful hunt). Some days there would be abundant food (woolly mammoth!). But nevertheless, our ancestors would not have eaten 5 meals each day. I have no scientific data to back this up, but my body tells me that giving it a break from constant digesting is much appreciated. The studies that have been done on Intermittent Fasting (check PubMed) show promise.

Second, Caloric Restriction (CRAN) has shown promise in promoting health and extending life (in mice). Intermittent Fasting, which is technically a 24 hours on, 24 hours off schedule, shows many of the same benefits as CRAN, such as increased beta hydroxybutyrate, marked decreases in blood glucose and insulin, and increases in neuroprotection and neuroendocrine response. But the beauty of IF is that it doesn't have the downsides of CRAN like decreased body weight. Take a look at some of hardcore CRAN practitioners...many are quite twig-like and quite a few lose their sex drive, all for a chance at having a few more years tacked onto the end of their lives. I love this quote: "I'm a much more considerate husband and father than I was prior to starting the diet. My testosterone is extremely low, in the ballpark of an average woman." Sounds like a blast. Robb Wolf has written some good stuff in The Performance Menu about Intermittent Fasting; Issue 6 is a nice introduction.

Also, I find that I think better when I don't have a belly full of food. This works out well at work. When everyone else is hitting their post-lunch lull, I'm still humming along. And I don't lose the 30 minutes or hour of work to eating. Similarly, my workout performance is better during my fast than if I have eaten within 4 or 5 hours before the workout. I'm stronger, lighter, and crisper during a fast than afterwards. The body and mind just seem to work better during short fasts. I surmise that this is an evolutionary adaptation providing peak performance right when it is needed: at food finding time. The body doesn't need such levels of energy and clear thinking following a meal as energy supplies are secure for awhile so it can devote the blood supply to the stomach for digestion.

Finally, it's hard enough to put together 2 or 3 perfect meals of meat, vegetables, nuts, fruits, and tubers. Forcing yourself to eat on a schedule is setting yourself up to eat subpar foods. And eating 5+ times per day is that many opportunities to eat foods that you really shouldn't be eating. I have very few chances to cheat on my nutrition plan each day since I rarely eat away from my house. And the cheat foods that are in my pantry aren't as detrimental as anything in a snack machine. Plus, it is easier to not eat than it is to eat just a little.

While I generally end up not eating breakfast or lunch and then chowing down when I get home, the real beauty is that I can break my fast at any point in time without a major effect. If I get overly hungry, I eat. I don't have to remain dogmatically tied to a certain eating schedule. If I'm hungry in the morning, I'll grab a small breakfast. If I get hungry at work, I can walk downstairs and grab a salad. That's the "ad lib" part of my fasting regimen. I find that following an this nutrition plan puts me much more in tune with my body than 5 perfectly timed meals ever did. I understand what is real hunger and what isn't. I aim for long fasts, but if my body says "uh uh," I eat.

I typically follow one of two eating plans each day. Right now, I'm not working out due to my shoulder surgery (which I'm recovering from nicely), so most days I get up, get dressed, go to work, come home from work, then break my fast with a handful of nuts while I make my patented enormous salad (~20 hour fast). This constitutes my first meal, which I follow about 2 hours later with another feast of meat and vegetables and plenty of olive oil. If I'm still hungry after that, I might coat some berries, grapes, and/or melon with coconut oil, coconut, and cinnamon for dessert or get ahold of some almond butter and get some more good fat calories in. Two large meals in 3-4 hours. When I am working out, I usually time my workout for early- to mid-afternoon and then eat some starchy carbs, protein, and fat an hour or so later, then I head home after work and have 1 big meal (15-18 hour fast).

Many people that follow a "compressed eating window" (eating the same number of calories in a shorter time frame, like my 18-20 hour fasts) find that they recover from workouts faster and contrary to what you would think, don't lose tons of weight. Until my recent bout of two shoulder dislocations and surgery (mid-May), I had gained about 8 lbs while dropping some fat, so probably a 10-pound muscle gain starting in Dec, with pretty big gains in the major lifts of deadlift, squat, and overhead press. So I was getting in enough high quality calories to fuel muscle growth while gaining weight and still losing fat. That's contrary to the popular belief that you can't gain muscle while losing fat unless you are a rank beginner, isn't it? It is possible if one is eating properly and lifting properly. Alwyn Cosgrove touched on this recently.

I've been asked a few times about "starvation mode" and catabolism (muscle breakdown). I don't know the mechanisms behind it, but my jump from 185 lbs (~9.5% bodyfat) to 193 lbs (~8.5% bodyfat) during the months of Dec to May certainly show that I wasn't wasting away and that a bit of catabolic action didn't harm muscular growth. Catabolism is every bit the natural process that anabolism (muscle growth) is. Art DeVany gave a brief description of the benefits of catabolism following a workout.

An easy way to get up to speed on fasting is The Fast-5 Diet. I dislike the author's lack of concern over food quality, but I think that's more of a way to make it marketable than anything else. I mean who really wants to hear that they have to get rid of their crappy food AND not eat for 19 hours of the day? Needless to say, a fasting protocol with high-quality natural foods is better than a fasting protocol with low-quality processed foods. It is also easier to fast on a low-carb diet than on a low-fat diet since carbs stimulate the appetite, while protein and fat are satiating.

One other thing I've noticed is that I appreciate my food much more. When I eat, I really savor the flavors, textures, smells, and colors rather than just mindlessly forcing more food down my gullet as I did in past days of eating every 3 hours. Fasting really brings an appreciation of the food that you are eating. Give it a shot.
