Not sure if Joan’s comment is tongue in cheek or not above, but If so, well played! Dr. Pontzer suggests after we reach equilibrium regarding incorporating exercise into our daily lives, we have the ability to manage roughly 600 calories worth of energy expenditure through hormone fluctuation, reproductive system alterations and the like internally (exercise above this threshold is the natural Ozempic). As you mention Michael, reaching this plateau in calorie burning means we’re reaping the most benefits we can from our exercise, those that the evolution of our species lead us to need.

I think most people think adding in exercise makes a sedentary person healthier, but Dr Pontzer suggests it’s a more accurate relationship to think about not exercising makes an average person unhealthy. Everyone should think of 4-600 calories of exercise per day as a mandate for a healthy lifestyle, but they can do it in whatever form they want!

As usual, great content. I look forward to these every M, W and F!

Like many American women, I have lost and gained the same pounds over the course of my life. I thought I had found the holy grail when I discovered Keto. And yeah, I lost weight. But was it because I was eating low carb, or was it because I religiously measured every bite I took.

One of my trainers long ago told me that weight is 10% exercise and 90% diet. So that’s always been in the back of my mind. It took a minute to recognize that if I eat 600 calories of junk food, I will definitely not exercise enough to burn that off. My solution? Stop eating 600 calories of junk food.

I’ve left keto behind. My BMI is higher than I’d like, but I lift twice a week and am heckin strong. I’m trying to learn how to eat to live, instead of living to eat. Great article!

I've been outrunning diet for the last 7 years. I started ultra-running (50Ks then 50 milers and now several 100 milers) when i was 30 after sustaining an injury to my shoulder in the gym. Before I started running 30-40 mile weeks i would fluctuate weight from 145-175. For the last 5 years i've been consistently 155-165 lbs - no matter what i eat. It's quite nice but I know it won't last forever. If i ever have to reduce my activity i know i will need to watch what i eat.

I wonder what the second and third order affects would be if the government mandated a much more rigorous lifestyle, i.e. an hour a day of moderate to heavy exercise? Beyond creating a more resilient populace, I'm sure lots of health care costs would drop, as well as mental health would improve. Would there be any downside?

And as a follow-on question: how does the government come up with "exercise guidelines"?

Does it matter if you get that hour in shorter sessions throughout the day?

Can't you read about Ozempic?? Don't you understand that weight and calories whether from "healthy" or not so are not relevant. Forget calories Hormones Rule. Anyone who pushes the body to extreme exercise unless this is the only way they can earn a living is essentially nuts and so what they eat is summed up by: Who cares?
