Wellness Wednesday for June 26, 2024

The Wednesday Wellness threads are meant to encourage users to ask for and provide advice and motivation to improve their lives. It isn't intended as a 'containment thread' and any content which could go here could instead be posted in its own thread. You could post:

  • Requests for advice and / or encouragement. On basically any topic and for any scale of problem.

  • Updates to let us know how you are doing. This provides valuable feedback on past advice / encouragement and will hopefully make people feel a little more motivated to follow through. If you want to be reminded to post your update, see the post titled 'update reminders', below.

  • Advice. This can be in response to a request for advice or just something that you think could be generally useful for many people here.

  • Encouragement. Probably best directed at specific users, but if you feel like just encouraging people in general I don't think anyone is going to object. I don't think I really need to say this, but just to be clear; encouragement should have a generally positive tone and not shame people (if people feel that shame might be an effective tool for motivating people, please discuss this so we can form a group consensus on how to use it rather than just trying it).

On Outrunning a Bad Diet

We've probably all heard the phrase, "you can't outrun a bad diet". There's certainly some wisdom embedded there, particularly for anyone that's just starting to get a handle on their weight and fitness - burning enough calories to significantly outstrip dietary intake isn't really an option for most people most of the time, and even if they do start burning quite a few calories, many people find it easy enough to outeat that burn rate anyway. Nonetheless, I find that the phrase irks me a bit, I think because people use it in a fashion that I think is stronger than what's consistent with either the general set of facts or my own personal experience. I've been thinking about this more lately for reasons I'll get to shortly.

As a bit of background, I'm a running enthusiast that picked the sport up in my late 20s when I had started to look at little doughy around the middle. After entering a couple races, I found that I really enjoyed the sport, wanted to be more competitive, and embarked on what's now a more than decade-long journey through the sport. Over that time, I've had ups and downs due to work schedule and injuries that resulted in my mileage fluctuating from a then-highpoint around 2200 miles back in 2015 down to about 1100 miles in 2020. Over the past couple years, I've been lucky enough to finally sort out both my work and injuries well enough to have set a new yearly mileage PR last year, knockout a great marathon training cycle to start 2024, culminating in a marathon PR to close the spring race season. During that time, I saw, "you can't outrun a bad diet" quite a few times on various message boards, and I'd quibble a bit with it on the basis that it sure seemed like controlling my weight had become a lot easier since I started my running life. Nonetheless, it was true that it fluctuated a few pounds and that I had to consider my calories a bit, so at least the weak form of the claim seemed true even for a consistent runner.

In the last couple months, that's changed. Now, I am outrunning a bad diet. After I bounced back from my marathon, I just started running every day with recovery days being slower and shorter rather than true rest. After finishing my morning run today, I'm at just a shade over 500 miles in 50 days, and the result is that I've lost a few pounds of fat. What's more, I'm seeing some additional muscular remodeling through both my torso and legs as I adapt to the consistently higher mileage. Going even a shade further, we got a dog and I'm walking more now too, with Garmin saying that my total movement per week is about 105 miles. I haven't made any conscious changes to my diet and haven't noticed any sharp increase in appetite, so without any dietary effort at all, I'm getting leaner.

To be clear, what do I mean by a "bad diet"? I think the first thing to note is that I kind of object to the term, I think most foods are fine in their proper time and place, and to the extent that food is "bad", it's contextual. Donuts are a terrible idea for diabetics, but there's nothing wrong with someone walking in from ten mile run and smashing a donut. At 140 pounds, I generally eat about 3000 kcal per day and I'm not at all particular about "eating clean". I drink too much beer (particularly big stouts and IPAs), I eat potato chips, I grill a lot of burgers, beef and onion fried rice is a huge go to, slow-cooker pork shoulder is great, cheese is definitely a go, fries or tater tots from the freezer are great, I'm happy to have pizza, and so on. It's not comically bad or anything, and I don't have a sweet tooth, but I just eat a lot of basically whatever I want.

So, is there any real point, any lesson to take away here, or am I just being a smug, pedantic asshole in saying that ackshually I outrun my diet? Well, admittedly there's more than a little of the latter. But really, I do want to note that I think people take the framing too far and undervalue exercise as part of maintaining a healthy weight. While it's true that a fat guy probably can't run enough to get skinny, the flip side is that a guy that isn't fat that takes up running or cycling really probably isn't ever going to get fat because of the way these sports change your relationship to food, giving you a real perspective on what you're eating and how much you need to eat for a given task. The metabolic impact is also crucial as easy aerobic work both burns fat directly and improves the capacity to use fat as a fuel for exercise. As with many other things, this isn't very helpful for digging out of a hole, but it's great for avoiding that hole in the first place.

I think the body is just resistant to change. There are some major things that seem to alter the body:

  1. Caloric restriction (including intermittent fasting).
  2. Exercise.
  3. Non-caloric dietary choices (keto, sugar intake, vegetarianism, etc).
  4. Sickness / poisons (your body trying to save itself and expending lots of energy, also poisoning from taking too many drugs legal and illegal).
  5. Age.

Even making drastic changes in one area you'll be held back by the other things. But get drastic enough, and you'll still break through the effects of the other things. This can be seen in the extremes. Take in zero calories and you will lose muscle mass no matter how much you exercise. A severe alcoholic is on the path to liver failure and death no matter how good their diet and exercise are. Be Michael Phelps and swim miles every day and you can eat 5000 calories of sugar for breakfast and still look like a chiselled Greek statue. Be old enough and no amount of dieting, exercise, or healthy living will save your body.

The original advice is probably helpful in the sense of telling people to avoid trying to do a thing that is very difficult. I think outrunning a diet specifically is very hard, because as you've experienced injuries are not uncommon. I think people can hit a death spiral with running. Where they need to run a dangerous amount to burn off their excess calories and fat, that amount of running leads to injuries. While they are injured they still have the bad dieting habits so things get even worse before they can get back to running. Rinse and repeat until they learn that swimming is a superior sport for exercise.

The death spiral point is interesting. As I get older, I realize over and over how much injury prevention and management is the long term key to fitness.

Amen to that, you can't do shit when a major joint is out of commission.
