Cleaning up my lifestyle (further)

With a career change came a shift in my lifestyle. I had also re-gained about 5-10 of the pounds I had previously lost during the last few months at my old job, despite a high volume of regular running. The resulting self-reflection led me to make wholesale improvements to my lifestyle.

Granted, my habits weren’t terrible to begin with: My diet and lifestyle at the start of 2018 was dramatically improved over 2015, let alone 2010-2014, let alone further back etc. But you don’t gain weight randomly. Even though I logged my food and found I was about even with my estimated calorie burn, I apparently was storing more than I could use. Along with my career situation, something clearly wasn’t right.


 

I cleaned up my diet in varying stages over the years, but over the past few months have really simplified it. At this point I’m challenging myself to eat as much whole food (cuts of whole meat, raw fruit, vegetables, rice) as possible. There are a lot of reasons for this.

  • It’s easier to track whole food items in Fitbit, and a lot harder when you eat something complex/processed, especially from a restaurant where you’re not privy to the ingredients let alone.
  • Processed food typically costs more per serving than its whole food counterparts. You’re paying for, among other things, satiety combined with immediacy. Sometimes I need that for whatever reason (it’s convenient at the end of a tiring day with few prior meals to house an Eastside Cafe frozen pizza and immediately get that 80-95 grams of protein, plus a bunch of calcium etc from all that fatty cheese). But usually I can find the space to prepare a fulfilling meal from whole food myself at home.
  • Processed food lacks key nutrients… especially dietary fiber, protein, and the underrated potassium. Plus, there’s far too much inflammatory and water-retaining sodium in processed food, and in many cases far too much fat. Since I run every day and am active in general, I need all the nutrients and as little garbage I can get.
  • You have no idea what 90% of processed food’s ingredients are, what they come from, what it does to your body long-term, etc etc. To get into the nuances of this would probably send us both into seizures, so let’s leave it at that.
  • Processed food is engineered to generate cravings to eat more food, which defeats a key reason to eat food (satiety i.e. not feeling the need to eat more food).
  • Hormonal balance and healthy hormone production is predicated largely on getting enough nutrients. Processed food is nutrient poor and disruptive. Whole foods closest to their natural state are nutrient rich.
  • I’ve found more ways to efficiently prepare and port whole, natural foods. I’ve had an on again, off again relationship with canned sardines, and now that I’ve found I can combine them with white rice prepared at home, they’ve become a lunch staple at work.

One problem that emerged at my prior job is that I started buying lunch more often. Previously I had brought food and eaten that every day, but even eating that food I was also sneaking out for hot bar meals. Granted, as I ran at a higher volume leading up to Vancouver I needed the extra nutrition. But that nutrition was also highly processed and was probably a key factor in my weight gain… not just for insidious extra calories, but the processed food probably wreaked havoc on my biology with inflammation and compromised hormonal function.

Changing careers coupled with a break from marathon training allowed me space to experiment with my eating habits, with different food choices (which granted were limited based on what I was doing for work and when: you have more freedom in some work situations than others).

Currently I’m on work assignment in an area close to two supermarkets with hot bars. Of course, hot bar food is not only partially processed, but expensive.


 

I wasn’t getting as much sleep as before. I woke up more during the night, woke up earlier, went to bed no earlier. I had plenty of time to sleep, yet my sleep was being disrupted.

This is something I still work on, granted. It’s a matter of forming the needed habits to eliminate the habits and sources compromising my sleep:

  • Remember to shut off all electronics, as well as disconnect power sources to those electronics, before bed. When I shut down my mobile and turn off the power to the modem and router (my laptop is already shut completely down at the end of every night), I find I sleep better. And while the evidence is disputed, there is evidence that electronics do interfere with sleep even when they’re off.
  • Call it a night during the 10pm hour. If I let my attention span drift and keep me awake through 11pm, that’s when sleep becomes a problem. Not only does it limit the hours I can sleep but it means more blue light later in the night, which is known to interfere with sleep.
  • Eating a satisfying meal within a couple hours of bed that doesn’t leave me wanting once I do lay down to sleep, since I know that hunger keeps me awake and can wake me up during the night.
  • Using my window A/C to keep the room reasonably cool during the night, as summer warmth does interfere with my sleep.
  • Making sure I get in solid exercise, usually at least a run, because I notice that on days I don’t exercise much I also tend not to sleep well.

 

Even though I avoided it because I run and need plenty of calories, I started intermittent fasting again. Basically, I skip breakfast and my first meal of the day is lunch, usually around 12:00 noon or 1:00pm. Along with the obvious tendency to eat less since I’m eating one fewer meal a day, going 12-16 hours between dinner and this 1st meal also improves fat burning during that time while helping to reset hormonal function. I definitely feel a difference, more so than hunger pangs. I’ll have black coffee and water in the morning at work, and that’s usually it.

This also improves the digestion and utilization of that 1st lunch meal, since your body is primed to get after whatever food you finally give it. At my current work assignment, it sets the metabolic table well for that 5pm run home from work. And that sets the table well for effective digestion of dinner later than evening. I definitely eat fewer calories, but I don’t feel at all broken down as I worried I would before if I ever went back to fasting. Quite the opposite.

There’s more I can say about Intermittent Fasting but I’ll save that for another time. Basically, I’m now at a place where it works well for me.


 

Since getting my act further together, my weight has gone back down to about 163-164 lbs, about 5 pounds down from where it had re-peaked during the end of my last career. My body fat has receded from 17-18% to a better 15-16%.

More to come on that front, but it’s looking good for now.

A marathon dress rehearsal run, and discussing in-race fueling options

Yesterday’s 6 mile run wasn’t so much about training, because at this point of the taper I’m pretty much as trained as I’m going to get.

The goal of the run was to practice marathon fueling. Never minding that the Vancouver Marathon uses low-calorie Nuun as their electrolyte hydration at aid stations (which isn’t effective like Gatorade because Nuun is low calorie and the calories in Gatorade are important to avoid late-rate bonking)… even if they used a better solution, race mixed drinks are typically mixed on-site, often poorly so and leaving your cup short on the actual electrolyte solution.

——

If I haven’t effectively implied it, one of my primary race goals is to avoid hitting The Wall, the moment of 100% glycogen depletion when you bonk and just have nothing left in energy. I’m obviously not a marathon expert by any means, but anyone who says it’s unavoidable is wrong.

For those wondering why they hit the wall late in a race… pretty much every resource points to a lack of effective in-race fueling. Your body burns mostly carbs when running at any pace beyond a recovery jog, and the faster/harder you’re running the more proportionally you burn carbs. At my size I burn about 120 calories per mile run, and at over 26 miles, that’s over 3200 calories burned.

Despite my weight loss and fitness, I still carry a good portion of fat. But fat burns glacially in exercise compared to carbs. While you can train your body to proportionally burn more fat, your fat will never burn anywhere close to as fast as carbs will during a run. Carbs become glycogen, which is your body’s primary fuel during a run. No matter how much fat you have… as soon as you tap out your available glycogen, you bonk. You’re running on auxiliary power and your body acts like it. So I have to make sure I get enough carb fuel to offer a chance of avoiding the wall in the final miles.

(Yes, your pacing and general hydration are also factors, but those are far easier to control. And all of this never minds that no matter what I’m absolutely going to be very sore and tired in the later miles. I accept that.)

According to the Hansons’ fueling formulas, my lower body stores around 1200 calories of glycogen, and should burn about 1000-1200 calories of fat throughout the race. If I properly pace myself I need about 600-750 calories in pure carbs to finish the marathon without hitting the wall. I also should ideally do it frequently in smaller portions rather than every half hour or when I pass the aid stations.

Even if courses provide nutrition, your best bet is to carry this nutrition yourself and consume it regularly throughout the marathon (which adds the benefit of allowing you to pick nutrition that works best for you). Plus, I still need to be able to physically get myself to a food resource and then back to the hotel, so I’m better off overkilling a little bit on what I carry and consume since my effort doesn’t end at the finish line.

Since I’m not Eliud Kipchoge with custom engineered drink bottles waiting for me every 5K, and point to point van service for transport… I’ve needed to figure out what to carry with me. I only have so much space in a belt pack, and carrying a 32oz bottle of Gatorade will obviously slow me down more than it’s worth, as every extra pound you carry adds 3-5 seconds to your mile time. What I use has to work effectively, and be portable.

Over the last few months I’ve worked on in-race fueling on various runs. I’ve experimented with gels (one packet is 100 calories), chews (one 6-chew packet is 200 calories), honey (a full 6oz flask is 568 calories), and for a while made a go with the minimally viscuous raw agave in a gel flask (6oz = 485 calories).

The agave is portable and easily consumable, but its simple sugars only replenish certain glycogen stores (albeit important ones for the body, like in the liver) and aren’t fully utilized by the body to run. I still found myself fading or even bonking late in 2.5+ hour runs despite consuming it every 10-15 minutes in-run… whereas the more engineered electrolyte sugars of Gatorade and similar drinks did keep me going.

I have found Clif Shot Bloks useful, but there’s an obvious problem: Trying to chew and swallow something while actively running at a decent pace makes it a little hard to breathe, which in turn makes it hard to effectively run until you’ve swallowed (and hopefully washed down) a given blok.

And, as I’ve found out the hard way, you definitely need to chase anything you consume with water or the issue will become much more difficult. In a race that will already be very taxing, those little aggravations could more quickly exhaust my energy stores before the end of the race… which defeats the purpose of fueling in the first place.

——

So anyway, I sampled the shot bloks once again yesterday while carrying 20oz of water. Perhaps active water use after consumption would help. Perhaps practice would help. They are the easiest and least messy of my fueling options, and if I can make them work it’s a better solution than gel, which is not only really messy and tastes like flavored motor oil but doesn’t feel good in digestion. I took one blok every 10 minutes and washed it down after swallowing.

The good news is despite attacking Cricket Hill (up and down) three times during the run, I felt energized after the run as compared to tired (as I often am when I take a similar run after work). The issue remains that, even with water, the moments between the blok entering my mouth and when it finally goes down remain difficult for my breathing and in turn my running. My heart rate did spike the first 3 times I fueled but stayed level the subsequent times… but my pace wasn’t great relative to my active heart rate, and I suspect repeating this process 8-24 times could slow me down and further complicate an already complicated marathon situation.

Now, I could just do it anyway, which I think is not a bad Plan A given this is already going to be a difficult race, and having usable fuel for the haul that works is better than not having such fuel. I think no matter what I’m going to bring Shot Bloks for the race, and if no better method presents itself I will just suck it up and pop one every 10-15 minutes until I cross the finish line.

I can also consider loading up a gel flask with agave and carrying it as well, saving the Shot Bloks for every 30-60 minutes or so, and just taking the agave on the regular. Both sources are palatable and digest reasonably well, and (though I will want to attempt using them together at home or in training to make sure nothing happens) I think having an adequate supply of both will cover my fueling bases.

The race has an interesting (possibly Canadian?) wrinkle, supplying bananas to runners at an aid station around mile 19. Aside from the concern of runners recreating a Mario Kart course with discarded banana peels, I think taking and eating one at the opportunity would also help. Bananas are my most common post-run carb-replenish fuel, so digestion is no problem.

And of course I plan to stick to a pre-race ritual: Eating a breakfast sandwich and chasing it with a shot of espresso a couple hours before the race. The nutrition from this must be important: Every time I’ve done this, I’ve raced well.

——

Admittedly, a lot of the above is talk-it-through thought process on my part. I’ve given this a lot of thought, because being able to finish the race with dignity regardless of finishing time is a high priority for me, and I know fueling in-race is vital to that happening.

Random things I learned over my time running, with no explanation

The harder your feet hit the ground, the quicker you’ll get tired and the more you will hurt.

You’ve got to eat like a bodybuilder: A whole food minimally processed diet anchored by lots of clean protein.

Sleeping well matters a LOT more.

The quicker your feet can step during a run, the easier keeping a faster pace will be.

In cold weather you will warm up after 20 minutes of running.

To race great you have to go out slower than everyone else wants to, and resist keeping up with them.

If you take advantage, life will give you lots of opportunity to practice running in little bursts.

If you can comfortably run in them, lighter and less-cushioned shoes feel better.

If your body can handle it, walking and weight training will not only make you stronger but help you heal between workouts.

You’ll know by feel when you shouldn’t use a pair of shoes for training anymore.

Perfect temperatures can actually be too hot for running.

Most people don’t understand the importance of fueling during long runs.

Most people over-fuel on shorter regular runs.

Big races are overrated, and consistent high-volume training is underrated.

Most people do their easy/regular/recovery running way too fast and hard.

If someone runs or bikes close to you on an empty path, they’re intentionally harrassing you.

Beginning runners try to do too much right away.
