Decades ago, society was more bullish on the importance of exercise in weight management. Just go jogging a few times a week, the thinking went, and you’d shed the pounds — never mind that you ended your run by heading to the bagel shop for a big, well-earned, carb-tastic breakfast.
In the last decade, much water has been thrown on the idea of using exercise to manage your weight, and the importance of diet has risen ascendant. Nutritionists and fitness trainers are quick to tell folks that “You can’t outrun your fork!” and “Abs are made in the kitchen!” Which is to say, that when it comes to preventing weight gain, losing the lbs, and keeping lost pounds from coming back, exercising a lot can’t compensate for a poor diet.
Which is perfectly true; diet is the critical factor in weight management. But, as with all cultural trends, once the pendulum on something swings too far in one direction, an overcorrection occurs in which it then swings too far in the other.
What’s gotten lost these days is that exercise is incredibly helpful in achieving and maintaining a healthy weight. While exercise alone (without a modification in diet) is only modestly effective in helping someone lose weight (the more, and more intensely, you exercise, the more effective it becomes), exercise has been shown to be significantly effective in preventing weight gain in the first place, and to be even more important than diet in preventing the regaining of weight after its been lost.
The efficacy of exercise in weight management is due to a number of factors, such as the way it increases lean muscle mass and improves metabolic health. But its most potent factor is one that typically goes unappreciated: the way it regulates appetite.
The Profound Effect of Exercise on Appetite
It’s often assumed that exercise will increase your appetite and make you hungrier. Some people who are trying to lose weight actually avoid it for that very reason.
But as it turns out, active people eat less than inactive people.
In our podcast interview with Dr. Layne Norton, he described a study done “in the 1950s looking at Bengali workers [that] looked at sedentary people, people with a lightly active job, a moderately active job, and a heavy labor job”:
And what they found was from the lightly active to heavily active jobs people pretty much matched their intake without even trying. They just ate more calories and they remained in calorie balance. What they found was the sedentary people actually ate more than every other group except for the heavy labor jobs.
This same result has been born out from more recent studies. As shown in this graph from one, the relationship between physical activity and appetite follows a J-curve:
So to reiterate here: even though they’re inactive, and thus have lower energy intake needs, sedentary folks eat more than even people with high activity levels (the only people they eat less than are those with very high activity levels, who because of the intensity of their activity, obviously have exceptional energy intake requirements). As your level of physical activity increases, so does your ability to match your energy intake with your energy expenditure.
What causes the mismatch between energy expenditure and energy intake for sedentary people, and the healthy coupling between the two for active people?
Well, regular, long-term exercise has been shown to have a kind of paradoxical effect on appetite: it does increase your drive to eat, but, this effect is balanced by an improvement in your appetite sensitivity — your sensitivity to the signals of satiety. So, you may feel a little hungrier overall, but when you sit down to eat, you’re more likely to stop eating when you’re full, and less likely to overeat. As you increase your physical activity, you may eat more, but this increase in caloric intake is matched to your increase in caloric expenditure; you intuitively couple your energy consumption to
Sunday Firesides. Sometimes the Critic Counts
“It is not the critic who counts.”
If this line from Theodore Roosevelt’s famous “Man in the Arena” speech is taken to mean that the individual who takes action has far greater worth than he who merely casts stones from the sidelines, then it can be adopted as an unassailable truth.
If, however, it’s taken to mean you should never listen to your critics, then it’s a mantra that cannot be universally applied.
T.R., after all, was a critic himself, and when he called individuals “fragrant man swine,” “little emasculated masses of inanity,” and “beings who belong to the cult of non-virility” — you can bet he wanted to be listened to (and probably should have been).
While adopting a blanket “f**k the haters” mindset may anesthetize the pain of receiving negative feedback, it comes at the cost of two key things:
First, you surrender a potentially helpful perspective.
We’d all do well to heed our inner voice and scorecard over that of the crowd. But we can lose track of that voice or allow ego to convince us we’re doing a better job than we are, and it can take an external observer to point that out.
Second, you forfeit — at least if you apply the “never listen to critics” standard with integrity/consistency — the right to be heard yourself.
Because if people shouldn’t listen to anyone else’s opinions, they shouldn’t listen to yours, either.
Little credit belongs to the masses of heckling, grandstand-riding spectators, who nine times out of ten, have nothing valuable to say. But to avoid developing what Teddy called “a mind that functions at six guinea-pig power,” it’s wise to recognize that sometimes the critic can count: when he’s someone you respect; when he’s someone who also has skin in the game; when he’s someone who’s got, well, a point.

How to Diagnose and Treat Heat Stroke & Heat Exhaustion
It’s been freaking hot around the world this summer. Here in Oklahoma we’ve had more than a dozen days in July alone with temperatures over 100 degrees.
The chances of suffering a heat-related illness like heat exhaustion and heat stroke go up during extreme heat. According to the CDC, between 2004 and 2018, an average of 702 people died annually from heat-related causes, and thousands more ended up in the hospital. Small children and adults over 65 are most susceptible to heat-related illness. However, it can hit anyone who works or exercises vigorously in the heat. In fact, heat stroke is one of the three most common killers of soldiers and athletes in training.
Below we share how to recognize heat exhaustion and heat stroke and what to do to treat both conditions.
How to Recognize & Treat Heat Exhaustion
Heat Exhaustion Symptoms
Heat exhaustion occurs when your body can no longer cool itself down through sweating due to a loss of water and electrolytes. Heat exhaustion needs to be treated as soon as you recognize it in yourself or others. Left untreated, it can develop into its more severe sibling: heat stroke.
Symptoms of heat exhaustion include:
Heavy sweatingCold, pale, and clammy skinFast, weak pulseNausea or vomitingMuscle crampsTiredness or weaknessDizzinessHeadacheBrief fainting (passing out)
How to Treat Heat Exhaustion
The goal of treating heat exhaustion is to cool the sufferer down and restore their fluids.
Move to a cool room. If you don’t have access to an air-conditioned room, at least move to a shady spot.Take a cold shower or bath. If that’s not possible, drape (do not tightly wrap — this will trap heat) cool, wet towels/cloths on the body. Turn a fan on these towels if you can. Remove extra clothing.Sip cool fluids, like water and Gatorade.
If heat exhaustion symptoms continue for an hour despite your treatment, seek professional medical assistance.
How to Recognize & Treat Heat Exhaustion
Heat Stroke Symptoms
Heat stroke is the most serious of heat-related illnesses. With heat stroke, the body has lost its ability to cool itself down, resulting in a dangerously high internal body temperature (above 104 degrees Fahrenheit). High internal body temperature is potentially life-threatening as it can cause seizures, organ failure, and rhabdomyolysis. Even if you recover from heat stroke, you can still suffer long-term damage to your heart, brain (creating cognitive deficiencies), kidneys (requiring lifelong dialysis or a transplant), and liver (also requiring a transplant). Heat stroke victims often die months after they’ve “recovered.”
To guide me on the intricacies of identifying and treating heat stroke, I talked to Dr. Sean Langan, a research assistant at the Korey Stringer Institute at the University of Connecticut. The Korey Stringer Institute specializes in research in preventing heat stroke deaths among athletes.
Heat stroke symptoms include:
Central nervous system (CNS) dysfunction:ConfusionAggression/agitation (Dr. Langan says you frequently see heat stroke victims bite and punch people)DizzinessFaintingSeizuresVery high body temperature (104 degrees F or higher)Red, hot, dry skin (no sweating). Sean notes that you rarely see dry skin in people with exertional heat stroke (caused by exercising or working in the heat). Those exerting themselves in the heat may still be sweaty, and you’ll need to be on the lookout for other symptoms, particularly CNS dysfunction.Throbbing headacheNausea/vomitingRapid breathingRapid pulse
According to Dr. Langan, the critical heat stroke symptom to be on the lookout for is CNS dysfunction:
You can have really fit people who have an internal body temperature of 104 degrees Fahrenheit at the end of a marathon who are fine. Their body is adapted to having that high of an internal temp so they don’t have any CNS dysfunction and they cool down quickly after they finish their race.
You can also have someone who has an internal body temperature of 103, but they’re experiencing CNS dysfunction. This person has heat stroke and needs to be treated.
If you see someone who’s been in the heat who’s showing signs of CNS dysfunction, your best bet is to start treating that person for heat stroke. To confirm, take their temperature with a rectal thermometer (it will give you the most accurate reading)
Podcast #678 Physical Benchmarks Every man should meet at every age
As men, we all want to be physically capable. We want to be able to save our own life in two ways: in the more metaphorical sense of wanting to preserve it in healthy, fit form for as long as possible, and in the more literal sense of being able to make it through an emergency unscathed. How do you know if you do possess that kind of lifesaving physical capability?
It’s time to do more than wonder, and really check in with yourself. My guest today has some helpful benchmarks that guys from age 8 to 80 can use to see if they’ve got an operative level of strength, mobility, and conditioning. His name is Dan John, and he’s a strength coach and the author of numerous books and articles on health and fitness. Dan walks us through the fitness standards the average male should be able to meet from childhood to old age, beginning with the assessments he gives to those who are 55 years old and older, which includes carrying their body weight, a long jump, and something called “the toilet test.” We then reach back to childhood, and Dan discusses the physical skills kids should become adept in, which were inspired by a turn-of-the-20th-century physical culturist who thought every individual ought to be able to save his own life, and which can be broken down into the categories of pursuit, escape, and attack. We end our conversation with the physical standards those in the 18-55 range should be able to meet, including how much a man should be able to bench press, squat, and deadlift, and the walking test that’s an excellent assessment of your cardiovascular conditioning.
