Should You Intermittent Fast? A Basic Primer on Intermittent Fasting

First, in brief:

Intermittent fasting can work sometimes with exercise, depending on what you do and how.

You should avoid intermittent fasting if you work out in the morning.

The more training you’re doing, the less likely it’s a good idea.

Most of those who practice intermittent fasting and train effectively only strength train as their only meaningful, intense exercise. Generally, their only aerobic training is whatever walking they do during the day, or very brief high intensity interval training… if they do any cardio at all.

If you don’t do much exercise at all, then yes intermittent fasting is a good idea. And you should probably get some exercise, but intermittent fasting is a good habit.

A General Overview of Intermittent Fasting:

Instead of traditional fasting, where you may go a day or more without eating… intermittent fasting is about eating all your day’s meals in a short window of time and not eating the rest of the day.

Even if you eat a similar number of calories, the long break from eating gives your body an extended metabolic break, which can help reduce inflammation and better promote healing and recovery. This is actually more of the benefit of intermittent fasting than the potential fat burning improvements that can occur during the fast.

There’s no calorie restriction on how much you eat during the food window. But, obviously, it’s going to be harder to overeat in a single 8 hour window than it would be if you ate meals throughout the day.

Still, it is possible to outeat the fast during the 8 hour window and still maintain or gain weight. The fast doesn’t cause you to lose weight in itself. While it’s obviously more difficult in a shorter window of time, you can still overeat. That said, intermittent fasting can help with food portion and weight control.

How A Busy Schedule Improved My Nutrition

I’m currently working in a fairly isolated location across town, and some weeks I’m working longer than 8 hours. My schedule many workdays is wall to wall booked:

  • Wake up
  • Perhaps run as time allows
  • Prep for work
  • Go to work and work 8-10 hours
  • Commute home
  • Work out if I didn’t get to in the morning
  • Eat dinner
  • Prep food and clothes for tomorrow
  • Go to bed.

On many workdays I can’t leave the client facility because I only have 30 minutes for lunch, plus even when I can the best food options are halfway across town. In this location there’s no supermarkets or viable restaurant options nearby. I won’t eat garbage fast food or something off a vending machine or convenience store counter. Even if any of it was satisfying (hint: doubtful), the near total lack of useful nutrients will crash my energy levels in the afternoon, in a job where I need to stay engaged and proactive.

And, of course, I’m now endurance training. I need to stay fueled for those morning and/or afternoon runs. I can’t just eat a minimal diet or whatever happens to be available and expect to perform as needed in these workouts. Plus, I have to maintain my overall health and not make choices that will contribute to illness or burnout. The food I eat has to support not just my general day to day health but what I am doing in training.

L-Theanine And Vitamin Timing

Whole Foods Market Double Strength L-Theanine 200mg Suntheanine Stress Response | eBay

Most people who take vitamin supplements take them all at once, usually at the end of the day after their last meal.

Other than the risk of overloading your digestive tract and most of them being passed instead of used, this isn’t a bad strategy… especially if your vitamins are fat-soluble and you’ve had a large, fairly-fat-rich meal for dinner. Sure, some will likely get passed, but much of what doesn’t directly go to your bloodstream for use could them get stored in whatever fat you end up storing, to be released in your bloodstream later when that fat is tapped for energy. (This in fact is why vitamin capsules contain oils: The oils are digested and stored as fat, and the vitamins absorbed can come along for the ride.)

This is beneficial for runners, triathletes and other endurance athletes. When they go to train soon thereafter, any of that fat that’s aerobically burned will also release those stored vitamins for use… at a time when their body may actually need it.

Now, that said, while I’ve talked about vitamins that can and should go together (like Vitamin K2 and calcium), some nutrients don’t go with other nutrients. And one key nutrient to keep in mind is L-theanine.

Food and Thermogenesis: How what you eat affects your body temperature

Energy produces heat. If you didn’t sleep through science class, they probably taught you this.

There are all sorts of circumstances behind what we now call climate change, the steadily rising temperature of the planet. But one key element is the fundamental existence of more human beings than have ever been on the planet in recorded history.

All humans produce heat. Every mechanical, electrical, chemical anything we have ever done produces heat. Vehicles and other machines produce heat when they operate. Anything we built that moves produces heat. Even the coldest fridges, freezers and air conditioners produce heat to cool what’s inside: The heat is just emitted out of the back or top of the device into the surrounding atmosphere.

And our bodies produce heat. The bigger we are, the more active we are, the more heat we produce. This is a key reason why your perceived temperature is hotter when you’re running than it is when you’re walking or still. You produce a lot more heat when you exercise.

Even the energy required to digest food produces heat. The act of digestion producing this energy is a little something scientists call thermogenesis.

Some foods require more energy from thermogenesis than others. This is one of the keys behind why it’s generally healthier to eat unprocessed meat and vegetables than processed sugar.

Insoluble fiber and most proteins require a lot of digestive energy for the body to digest its nutrients. These foods are highly thermogenic.

Meanwhile, chemically refined sugar is by design quickly digested, as these foods are chemically engineered to not satisfy you hunger and make you crave more of them. These foods are lightly thermogenic.

You can eat 500 calories of sugar cookies, and still be very hungry immediately after eating them. Meanwhile, you can eat 500 calories of steak, and be so full you won’t want another bite of anything for several hours. And woe is the poor soul who tries to eat 500 calories of broccoli… if he even manages to get it all down (1 cup of cooked broccoli is about 60 calories). He will end up spending a regretful amount of time on a toilet at some future point.

Broccoli and other vegetables are among the most thermogenic of foods. Many require more caloric energy to burn them than the calories the vegetables themselves contain!

Now, why bring up global warming when bringing up the thermic effect of food? Is Steven saying that broccoli causes climate change?

Energy Availability and making sure you don’t undereat when training

Currently I’m tinkering with my diet, not necessarily the foods but the meal timing and the calorie macros.

It’s not so much that my weight loss has currently stalled. In fact, it did drop to a month-low 168.9 lbs over the weekend… though it has been tough, slow going to move the average down.

I’m trying to naturally maximize my energy levels, which when I’ve fasted had tended to stay low. This means I need more nutrients around these times, which indicates I should stop fasting.

However, I went back through my RRCA training course materials… mostly because I was walking on a treadmill for an hour and the spiral-bound book was one of the only books I had that I could suitably read while on the treadmill. In any case, I went through the information-laden appendicies and it includes a robust booklet on nutrition by the IAAF.

In the IAAF’s Nutrition materials, they mention an interesting stat: Energy availability. The idea of Energy Availability is that aside from calories burned in exercise, the body has a certain number of calories it needs to rebuild and recover from that exercise.

Twelve (12) Training and Lifestyle Tips For Fat Burning

There’s a lot I could say about fat burning, and there’s a legion of users-guide material throughout the internet world about methods to healthy fat burning (and many more about unhealthy fat burning ideas, which I will not bother to cover). I could write a piece about a dozen topics.

But I think it would help you to get some actionable tips in one place, and perhaps a shorter bit of writing on each of those in one place may help you more in the present. I can always cover all of these topics in additional pieces later.

So instead, I’m going to put a dozen topics into this long post, and succinctly get into why you should make it a standard or best practice.

If you’re trying to burn fat and struggling with it, these tips should help spur things along or keep things moving in the right direction.

Avoid the Novel Coronavirus (and other illnesses)

Coronaviruses are in general quite common. You may actually get one once every year or two. However, we’re experiencing mass panic over the current novel coronavirus strain, which has killed a few thousand people in China among the many thousands infected, and sent entire nations into a panic.

There are a handful of truths regarding this novel coronavirus:

  • Most of the people who contract the worst form of the novel coronavirus will make a full recovery without any required medical intervention, just like most people who get a common cold or the flu.
  • The death rate of the novel coronavirus is actually quite low. About 1-2% of people who have reportedly tested positive for it have died from it, and almost all of the deaths have been in China and Italy, where tens of thousands (again, nearly all known cases) have been diagnosed. Virtually all of the people who have died from the novel coronavirus either have seriously compromised immune systems or live in abjectly unsanitary conditions (and that’s assuming all stats are accurate, which is highly questionable). Sure, I’d be worried about the health of either population, but the vast majority of those reading this are in a much better situation.
  • Regardless of anything anyone does, there’s little people can do to prevent its overall spread, quarantines or not. It’s an airborne virus, and a common type of virus at that. It’s like trying to eradicate or quarantine the flu or common cold. Good luck.
  • The current quarantines are more a product of systemic panic than necessity.
  • Other governments are semi-thoughtlessly following in kind with their own over-reaching quarantines, not realizing they’re parroting a needless overreaction from a totalitarian government. This never minds major events that have elected to cancel said events in response to the hysteria. In most cases, they’re making a panic-driven mistake.

All of this said, this novel coronavirus strain is worth concern, the same way any major flu strain or flu season is worth concern.

As always, there are things you can and should do to safeguard yourself from illness and give your body the best chance to flush and resist that illness should it find its way into your system.

However, I have useful advice beyond the standard “wash your hands, take your vitamin C, avoid crowds, etc”. Here are some tips for you to help your body and immune system withstand any potential exposure to any illness, not to mention the novel coronavirus.
