To be fair, our diets and lifestyles changed drastically in the 20th century. When we're bombarded with advertisements of highly caloric, processed, sugary foods engineered to flood our taste buds and trigger dopamine, we can't be surprised that people get addicted to it. Combine that with forms of entertainment, transportation, and a work culture that keep us sedentary, and it's no wonder many people struggle with b…

indeed, a lot has changed from when we lived on rural farms doing manual labor. People aren't going back to the farms, so we need to adopt new behaviors and norms around self control. There is simply no viable alternative.

To frame the discussion as one of either/or alternatives is self-defeating, a more productive framing is what are the various strategies we can employ to reduce obesity?

There are plenty which are unrelated to self-control or personal discipline. One is a sugar tax (not a huge fan personally but it exists).

One I do like is to regulate the advertising and labeling of food. Frankly I'd like to know how many calories I'm eating or being persuaded to eat, pretty much all the time. This is a work in progress with the FDA gradually expanding the types of restaurants that are required to disclose caloric and nutrition info about their food. Frankly I'd like to see it required in advertisements too, if you're advertising a pizza, the advertisement should disclose that there are 2,000 calories in that pizza, many people actually are not aware.

Not that I ever thought they were serving health food at the Cheesecake Factory, but I recently learned that their peanut butter cheesecake is 1650 calories per slice! Almost a full day's calories in one slice of cake! Nearly everyone I've talked to about it knew it was a gut buster but no one guessed that high.

Those cheesecakes are only for special occasions now and it's because C.F. is required to disclose calories, I'd be fatter if not for this simple government intervention. Nothing to do with self control. Apologies to C.F. but with the nation's obesity rate cresting 50% I consider this a wholly reasonable imposition on their free speech rights or whatever.

This sounds ridiculous until you go to Amsterdam see that few wear helmets there. And everyone is cycling. They might be more inclined to cycle because they don’t need to wear a helmet. After years of cycling with helmet you get so used to it and it doesn’t bother you. But how many skip the bike because they never got used to wearing a helmet?

more like because it’s safe and there are penalties for injuring pedestrians and cyclists, and because the infrastructure is great. not riding a bike because a helmet is ??uncomfortable?? is ridiculous and probably self-selecting

Over the past 11 months, I've lost 122lbs, from 330lbs to 208lbs. (May 30, 2023 - Today)

For the first 2 months, cardio was not part of it. Really focusing on diet, reintroducing myself to portions of Whole Foods to hit macro goals. Really focusing on vegetables and protein, large quantities of low calorie foods that digest relatively slowly to keep me satiated for long periods. They're also quick to digest.

I was always active, even at 330lbs I would mountain bike (ascending and downhill) comfortable on black diamonds, same with snowboarding. This continued, but I didn't try to explicitly do and track cardio.

After I lost 35lbs, I added CrossFit once a week. Then 2 times a week. Then 3 times a week. I noticed that olympic lifts and squats would cause extreme systemic fatigue, and would leave me dizzy and out of breath. After a couple months,

I stopped doing CrossFit due to an injury caused that that effect, and started isolated training for muscle hypertrophy utilizing machines for 5+ days a week, but missed the cardio that CrossFit gave.

I was about 260lbs at this point, and started with incline walking at about 3mph at max incline for 40 minutes. Then I started to begin my cardio with a 6mph run until I was out of breath and a high heart rate, and then began the incline walking.

After a week or so, I began running the a mile at the fastest speed I could, then switching to incline walking until my heart rate dropped, and alternated running and incline walking for 40 minutes.

Then, in November, I ran my first 5k in 34 minutes. I was hooked. I walked a couple minutes of it in the middle, but was pround myself. Today, I can run a 5k in 25 minutes if I push myself.

Today, I ran 5 miles without stopping with several hundred feet of elevation gain.

Cardio health is life changing. I used to be tired walking up large sets of stairs, and it was embarrassing to not be able to hold a conversation for long while walking up stairs.

It's also a myth, perpetuated by highly trained athletes that you cannot gain muscle and do cardio, or that you cannot do these things while in a caloric deficit.

I have lost nearly 1% of my body weight per week as a vegetarian while gaining significant muscle mass (today, I am about 15-17% body fat at 6'1 and 208lbs).

The biggest thing I can say is it's never too late to start, and it's important to be consistent and find what works for you. At 32 years old, I have added years to my life, and feel and look better than I ever have.

Also, cardio gives an amazing dopamine rush that beyond addicting. Highly recommend it. But don't forget the resistance training.

Anyone can do it. One day at a time.

As someone in tech, the process of rebuilding yourself is addicting once you start to see progress on every front.

VO2Max Increasing. Resting Heart Rate Dropping. Waist Shrinking. Chest, Arms, Legs Growing. Muscle definition increasing. Lift PRs increasing. And you look better in clothing.

Not sure how true this is, I heard in the Joe Rogan podcast, cardio vascular fitness, like the extreme kind correlates with nearly the entire disease spectrum. It doesn't apply to something like 'acts of god' type things like Cancer or COVID. But it seems to be the best bet against aging, and other diseases.

My favorite exercise in this regard is Swimming and Kettlebell training.

Disclaimer: This is not an endorsement for Swinning and Kettlebell training.

Smoking does reduce appetite and therefore can help in weight loss/getting in shape. (I don’t smoke)

I have definitely seen more than a few smokers who quit gain weight, no idea if it's picking up a new addiction or if the smoking subdued their hunger pangs, or some combination thereof.

Nicotine is absolutely scientifically known to be an appetite suppressant.

I biked through Amsterdam as a commuter along with everyone else for a week, and it just blew me away. Everyone was absolutely predictable and part of the “school of fish”. No hesitation or ill-conceived politeness. It was only a week but it was so refreshing. I think about this experience daily when driving because I think of how much time would be saved if people just knew absolutely when to take their turn and too…

This doesn’t work when driving primarily because cars are generally moving a lot fast and are less maneuverable that bikes in avoiding conflict.

The poor VO2Max estimates on the Apple Watch is why I'm phasing out of wearing one. I track my actual VO2Max measurements in Apple Health via a shortcut, and I don't need a daily made-up number messing up my data.

Why is Vo2Max important for people who aren't professional athletes? It's not that I'm not curious about my number I'm just not sure how helpful it is going to be - I need to understand what pace I can hold 5k, 10k, 21k and eventually 42k. I think the best way to know that is racing again and again and getting a good feel for your aerobic / threshold zone. Whether my Vo2max is 51 or 52 - does it matter to me?

To me it's a measurement of roughly how not-dead I am

I was blown away at just how little exercise is required to significantly increase your lifespan: 20 minutes a day, 3 times a week. That's it. The Copenhagen City Heart Study, published in the Journal of the American College of Cardiology in 2018 found that light jogging for 20 minutes a day, 3x a week reduces all-cause mortality by 78%. That's insane.

It's a logarithmic curve. On a 1 to 10 scale, increasing activity from 0 to 1 provides a large decrease in mortality. Going from 1 to 2 another big jump. But 2 to 3 is less, until finally it plateaus.

But yes, people don't realize that even just walking at a moderate pace for 20 min 3 times a week provides huge benefits if you are otherwise completely sedentary.

Define substantial. I find that incredible. EDIT: Now that I've seen the replies, I realize that this is from a very low baseline. I'm personally going to the gym four to five days a week already and my own cardiovascular fitness has not seen much of an improvement in many months.

n=1, but I can personally attest to going from average sedentary 29 year old to marathon running shape in roughly 3 weeks of continuous hiking 8 to 10 hours a day in the Appalachian mountains with a pack that was about 35% of my body weight.

I have a hard time believing that a truly sedentary person could do that.
