Yes but the macros are more or less comparable? It's chicken breast with extra saturated fat and stuff.

I think you are unfairly overly minimizing the impact of the "extra saturated fat and stuff".

This reminds a little of Usain Bolt famously having chicken nuggets before his final at the Beijing Olympics. Although hardly indicative of a bad diet that he may or may not have had. I think as well there is some difficulty with variability between people that isn't clear or maybe doesn't matter at scale. The article linked study was across 43 nations with 4213 adults. Yet there may still be individuals who can argu…

I do bouldering and I eat fast food multiple times a week, I can definitely outclimb my poor diet... I probably helps that I don't eat breakfast though... It's well known though that as you build muscle, your rest calorie consumption increases, so probably if you build/maintain enough muscle, then you can just outrun your intake, since you consume more without doing anything to start with...

I don't think we're talking about "unhealthy diet" solely in the sense of eating unhealthy foods. The real issue is calorie intake. If you are taking in an unhealthy amount of calories -- regardless of the source -- you are unlikely to be able to outrun that diet.

And you're kinda agreeing with that point: you eat fast food a few times a week, but you don't eat breakfast. So perhaps your caloric intake is still at a reasonable level for your body, regardless of the source of those calories.

I just lost 50 kilos in 10 months. Quit sugar, walk 10km a day and most importantly ate almost only soup. So kind of low carb vegetable oriented stuff.

The 10km per day thing is certainly great for your health, but I suspect you'd still have lost most of that weight if the only change you made was to your diet.

I have been, rather lazily I suppose, trying to tweak my diet in such as way as to lose weight; and with little to show for it. I'm not sure that there is much if any processed food still in my diet (maybe just the English muffin in the morning?). I stopped buying/drinking soda pop decades ago (a low-hanging fruit indeed — I lost almost 10 pounds within a month of making that dietary change alone). And since I have t…

I think it's great to try to eliminate foods that you believe aren't healthy (in any quantity) from your diet, but if you replace those foods with a quantity of other foods that keep your caloric intake more or less the same, you're not going to lose weight.

> ... I ate very small portions for each meal.

That's what does it. Decreasing the calories you eat.

> I'm not sure why I can't change my habits such that I continue to eat those small portions (now that the fear is gone).

Because, like all of us, you're only human, and human psychology, plus how our stomachs and brains signal each other, is complex and sometimes makes it really hard for us to achieve our goals. It sucks, but that's how it is. This is why the semaglutide weight loss drugs are proving so effective: they short-circuit some of that and help you just not want to eat as much food.

If drugs aren't for you, try counting calories, and use an app to help with it and help keep you honest. I experimented with it back in 2017 or so, and it actually did cause me to be more mindful about how much I ate, and made me think twice if I'd already hit my calorie budget for the day but wanted more food. I was pleasantly surprised to find I actually did lose weight. I didn't stick with it (don't remember why), but it did work for me for a time.

There is a simple and very low-impact exercise which affects obesity: the fork put-down.

Citation needed. A quick search suggests this is mainly pushed by influencers and life-coach type people. I'd be incredibly skeptical of anything pushed by people like that, unless it's backed by research... which doesn't seem to be the case here.

A Big Mac is over 500 calories.

Running, not walking, only burns around 500 calories an hour.

You can eat a Big Mac in 5 minutes and it'll take you an hour of running to burn it off.

For most people, a 1 hour moderate run is only about 1-2 cookies worth (and only half a Crumbl cookie). Even a marathon run might only burn 2000 calories . a chipotle burrito is 1600 .

> It's actually best to do most of your activity undernourished, as it helps develop true intuitive nutrition feedback sensation. You'll start to sense how every macro and salt feels when you ingest it.

Not exactly my experience.

My did a exercise schedule involves climbing a mountain every week. The mountain is about 400 meters (that's ~1312 feet, or more than four American football fields laid end-to-end) tall, and the exercise was usually done during afternoon (1 or 2 hours before dinner) without eating lunch.

After two mouths of that, I've noticed:

1. My weight or belly size don't really changed much. I also notice that some people who also frequented the mountain have big bellies.

2. I got very hungry after that, which triggers me to eat more during dinner, usually salty food.

3. The delight of salt becomes craving, probably due to the lost of liquid/electrolyte through sweat (and tears, probably).

4. For comparison, I stops craving salty thing the next day.

I guess you need to actively suppress some of your inner urges to really make the "nutrition feedback sensation" work. Otherwise, exercise more only leads to consume more.

P.S. Also, doctors really can't recommend doing heavy physical activity with empty stomach, as it might increase your heat rate or something (I might be hearing it wrong). I've since changed the schedule so I can eat something before start climbing, though my belly size still remained the same, and I'm still craving for salty food if uncontrolled.

But maybe it's just because I don't know how to do it correctly.

Unsurprisingly, the title is sensationalist and not representative of the study.

After I started doing moderately long and fast bike rides (200+km/week, flat and hilly terrain, averaging 70km/ride during summer, 100+ if I have enough time), I have found that:

- compared to "not much exercise" (some periods during winter), it modulates my hunger. I do not eat more, or only proportionally.

- when the rides are longer than cca. 50km, I start losing weight (not just water, weight, sustained)

- after several days with no exercise, my hunger starts to increase again. In other words, I have to exercise to not overeat. I don't understand this effect, but it works for me, and it's been like this for many years.

Yet perhaps taking a huge time commitment during which you won't be able to eat much is exactly what is needed.

I'm 5'6", 165lbs, I bike 6-8 miles every day and do resistance training 6 days/week. I also have limited myself to 1800 cals/day and at least 130g protein. For two years I was biking 6-8 miles every day, doing resistance training and maintaining 210lbs which, at my height, is bordering on clinical obesity. If you could be healthy just by training and eating what you want I would have done it twice.

Your bike ride is too short to lose weight.
