It was 5 year ago, I don't really remember...

I guess one question is: how big was it? If it couldn’t fit more than 25 people, it was definitely not a US supermarket...

No, it was big supermarkets. Definetly more than 25 peoples.

I was a bean pole into my early twenties, and would have been 20 lbs skinnier still if not for cycling. I never gained any more weight until I dumped the classical advice and did my own thing. Everyone tries to compress a workout into a single time interval in the day, where you do n sets of each exercise and then go home. To do three sets in three minutes, you're going to have to pick a very conservative goal. Doing…

What were the exercises you ended up doing at home spread out over the day? Given the current situation, seems like a unique time lots of us could try out that type of workout.

i just do laps around the house

I just checked some hamburger buns that I bought from my local grocery store. They were in the middle price range. Enriched flour (wheat flour, barley malt, niacin, reduced iron, thiamine mononitrate, riboflavin, folic acid), water, potato flakes, yeast, wheat gluten, sugar, 2% or less of: salt, soybean oil, soy flour, sodium stearoyl lactylate, corn flour, extratives of paprika and turmeric, calcium propionate, calc…

The only bread I've bought in a long time is supermarket (ciabatta) rolls:

> fortified wheat flour (wheat flour, calcium carbonate, iron, niacin, thiamin), water, extra virgin olive oil (2%), fermented wheat flour, malted wheat flour, salt, yeast

They're not the cheapest of course, but hardly some absurd luxury at 33.8p each, they're a lot nicer than squidgy cheap rolls that are unlike anything you could reproduce at home or see a baker produce, and have pretty much the same ingredients list you'd use at home, if you used commercial yeast and bothered with three different flours.

And there's no selection bias or anything - I haven't looked at the ingredients list before, that's not why I buy them. I buy them because they're nice enough and so far I haven't bothered to bake rolls, mainly because my demand for them is more erratic than slice[able] bread.

Reading through the post makes me thinks that are we eating unnecessarily? 3 meals a day have become the basic necessity for most. Our ancestors used to eat as much as they could because there's no guarantee that they will have enough food until the next hunt. So, the body will go into a state we call "hungry", which reminds us to eat. However with such plentiful of food available (know it didn't came easily, at leas…

> I am able to reduce my daily meals to 2 by having a bulletproof coffee in the morning. For whatever it's worth, two tablespoons of butter on your coffee is 204 kcal according to Wolfram Alpha. Even Bulletproof says things like "Bulletproof Coffee is breakfast" and "curbing your hunger with food that keeps you full for hours. Bulletproof Coffee checks those boxes." which I read as saying that they think of it as (li…

True, I don't believe anything that is marketed/advertised as "miraculous". While bullet coffee doesn't give me superpowers, it does however helped me to "replace" (skip is a superstitious word, I agreed with you) breakfasts that would otherwise be full of sugars and such. The hunger disappeared from 6am (when I wake up) until around noon.

I think diet is not just about the food and nutrients but also the lifestyle. You can't expect someone to always be taking meticulous steps in measuring their intake, most will slip away. Start trying out small adjustments to see whether you can make it a habit, else it is not a good idea.

For me, the coffee helps me stay full (physiological or physically) and don't make me grumpy the whole morning, yet still having the energy to crush it.

I am actually looking for more replacements/practices that would allow me to eat just enough and suits my lifestyle, instead of following a specific regime that is coupled with courses that they sell you.

Likewise, HFCS has about the same blend of sugars as honey, yet it is considered unhealthy and honey is considered healthy somehow. I'd like someone to explain how that works.

Honey is only considered "healthy" by people who know nothing about nutrition but who think "natural" is automatically good [0]. Honey is no better for you than HFCS, but no worse either (except in infants because honey often contains botulism spores that infants cannot fight [1].) [0] https://www.glycemic-index.org/high-fructose-corn-syrup-vs-s... [1] https://www.fda.gov/food/alerts-advisories-safety-informatio...

The observation is, I think, based on the top level post mentioning:

> ban all added sugar, except (real) honey in reasonable proportions.

As if there is something "magic" about honey that makes it OK as opposed to all other sugars. There is not.

You're right - there are 40,000 grocery stores in America, and only 30,000 Dollar Stores and their like. So less than half of Americans buy from Dollar Stores, if patronage equals frequency of the store. Buts Dollar stores are growing fast. That won't be true for long. I wonder at the "make their own meals". Maybe from packets or reheating frozen stuff. But the meat counter sure isn't the largest section in the groce…

That's assuming people go to the Dollar store specifically to buy food instead of going to the grocery store, which is certainly not the norm. People go to the Dollar store to buy food containers, snacks for a road trip, batteries, toothbrushes, etc. That's like assuming people buy groceries at the hardware store; the intended purpose isn't the same. At all of the American grocery stores I've been to, the unfrozen me…

Sorry, should have been more clear. The Dollar Stores are taking over grocery business across America. Its their most popular item (grocery) and many, many people's sole source of groceries. There are many articles about this, and it was even discussed here on HN some months ago.

I think its maybe a 'first world' view, that every body goes to Dollar Stores for the same things the upper class go there for. One source noted there are many times more Dollar Stores in Texas alone, than WalMarts across the entire USA. Gotta be a reason, and it isn't batteries.

The 'unfrozen meat section' is a prestige-item display case with really a trivial amount of product on display compared to the square footage dedicated to it. Vs every other section of the grocery, with racks 5-10 shelves high crowded with products. I honestly buy meat at the butcher counter maybe once a month, for a special occasion. Not a lot to do with 'what I usually eat'. Maybe its different for others.

Ah, the Americans... ;-) As a Dutch person living in Amsterdam, I completely agree. I noticed when I visited SF a few times (and California in general) that: - Vegetables are more expensive - Bread is sweetened (there goes my breakdfast) - Bread sucks (yep, I said it, basic bread should be thrown into the thrash can) - Basic cheese in the US is a new species, and I am afraid of it I went around these 2 issues by buyi…

> Bread is sweetened > Bread sucks I spent some months working in Houston a while back, and this drove me crazy! I mean, why on earth would you sweeten bread?! Another thing that struck me was how many ingredients everything seemed to have - you could pick up just about any item in a grocery store, and it was pretty much guaranteed to contain 10-30 ingredients. Even the bread. > Basic cheese in the US This too - most…

As a Brit living in the US, I have a real problem with the sugar in bread. As a bread lover I detest it. Everything I eat DOESN'T have to be sweet. I can't stand it and I avoid it as much as possible.

In the last few years, I've started making my own sourdough bread (salt, water, flour, homegrown sourdough yeast) with no chemicals and I'm loving it. I can't remember the last time I've bought bread. (Dutch-oven method)

>most cheese was of the horrible processed variety

I had this experience as well, but in the last few years, things have massively improved IMHO. Don't go the deli section (where they cut cheese), go to the area where there's brie/english-chedder etc. However Wisconsin has really stepped up to the plate and now creates very reasonable European styles cheeses (of course, more expensive). It's worth trying it again if you've not done recently.

Reading this brought back another memory - cinnamon! Now, I like cinnamon as much as anyone, but why the hell is it added to everything in the US!

McDonalds lists the ingredients in their foods here: https://www.mcdonalds.com/us/en-us/about-our-food/nutrition-... Their hamburger doesn't look any different than what I would make at home. I don't have any grocery store bought buns in front of me, but I assume it would have similar ingredients. The pickles are not the most natural, but once again, it's not much different than what I would buy in a grocery store. T…

And here we get at the root of the problem with the North American diet... The fact that people think an ingredient list like this is acceptable or 'not that bad' is a problem. The 'white bread' ingredient list looks nothing like real bread. Sugar? Oil? These are ingredients in muffins and cakes, not bread. The wheat they use has been processed to the point that a few key vitamins have to be added back just to make i…

No one's claiming that McDonald's hamburgers are super healthy and that we should be eating them every day, just that they're no worse the typical home-made burger. But they're also not bad. The problem with the average American diet isn't really the ingredients, but the size.
