> A given person, in 2006, eating the same amount of calories, taking in the same quantities of macronutrients like protein and fat, and exercising the same amount as a person of the same age did in 1988 would have a BMI that was about 2.3 points higher. I think the recent obsession with macronutrients is a big part of the problem. I'm not sure if the macronutrient ratio I eat has changed much from when I was growing…

I agree, the macros look sort of the same, but the source of those calories is much different. Just the types of cooking oil we use has changed a lot. Look at what goes into cookies now. It used to be butter, now I've seen recipes with canola oil. (if anyone tells you to use canola oil in your baked goods, ignore them and use butter!) There is evidence that gut bacteria is passed down from generation to generation, w…

I think this is spot on, and came to comment likewise... I think the types of product we are using for our macros is way off base from even a few decades ago. I only had a little glimpse of how much so because I know someone very allergic to soy, and it's in almost everything these days.

I don't think that most things in particular are necessarily bad for you, but it might be worth taking a few steps back and switch to less processed foods... I don't think organic makes much of a difference for most foods (aside from berries)... But using oils that have to be heavily refined, perfumed and dyed to make them palatable doesn't make so much sense.

There's also recent studies on the affects of artificial sweeteners on digestion, trans fats and a bunch of other stuff. I think the push towards vegetarianism, low-fat, low-carb, etc as fads combined with industrialization of food has done a lot of harm to the public.

If you're young and relatively healthy, avoid processed/refined foods as much as possible, eat a variety of things and don't consume too many calories on a weekly average, and you should be okay. I'm 40, diabetic, insulin resistant, and wish I'd received that advice when I was younger.

I just think it sucks how much it really costs to actually cook for yourself... over the weekend I made 3 different pots of soup to have this week. I had some chuck roast that I braised in beef broth (store bought), used the roast in a menudo inspired soup (I don't like tripe), the braising liquid was combined with mushrooms and onions for another soup... I used the left over carcase from a roasted chicken to make another broth that I then used to make vichyssoise (sub some potato with cauliflower and parsnips). All told it cost about $160 for everything with about a gallon each of three soups... breakdown to 2-cup servings comes out to just under $7 a serving for a low-gl diet with a variety of veggies... That doesn't count adding other protein in my diet too.

Now make it a family of 4-5 and that budget is too high for families making under 40-60K/year. It's no wonder that boxed mac & cheese, hamburger helper and the like rule the roost at home along with the dollar menu at fast food places. With all the heavily refined, packaged, canned, frozen and just plain overly processed food that we all consume too much of, is it any wonder why we as a society are experiencing the problems we are?

I don't know how well supported it would be, but would really love to see food/nutrition/cooking as a core material in elementary schools... Actually bringing cooking into school lunches with a required prep rotation for all students would go a long way. It would cost more than those programs do today, but is using subsidy trades to turn chickens into chicken nuggets for school lunches really a good thing?

I don't have access to the study, but I suspect it doesn't say what The Atlantic is saying it's saying. I lost weight: I went from 340 pounds to 214 pounds in exactly a year, and then bottomed out at 184 eventually (I've been purposely trying to gain muscle lately, which has been causing my weight to meander in the 190s since then). My caloric intake hasn't changed in a way that can explain such a weight loss. I went…

I did the same for a bit over a year (went from 460# to 360# that year), minimal activity.. since then I've hovered between #365-380 though... I haven't been as strict as that first year... A couple months ago I spent two months relatively high stress and ate a lot of fast food.. was inching towards 390 again... The past 2 weeks have been back on track (staying fairly strict in my diet) and back to 370 again.

It's purely anecdotal, but the fewer grains I eat (I do have some legumes, but try to limit them), the better I do all around. In general if I stay under an estimated glycemic load of 100/day, I loose weight with not other real changes in terms of calories or exercies.

Staying away from soda (Diet Dr Pepper) has been much harder... mostly drink water, but have a soda about every other day. I try to cook about once a week, usually soup that's easy enough to eat during the week and supplement with some meat along with fruit & nuts. It isn't easy, especially the first week... also, it's definitely more expensive avoiding heavily processed foods all around.

Weight gain is simple: calorie intake - calorie expenditure. The amount of calories in our food tends to go up over 20 years. Doing the same activities consumes the same amount of calories after 20 years. Thus we would have more caloric surplus, and likely gain more weight than people 20 years ago with less caloric food. Pretty simple imo.

> The amount of calories in our food tends to go up over 20 years.

RTFA, please. Paragraph five, specifically.

Its strange really. I'm on a ketogenic diet, and hear people preach the caloric balance constantly, that it doesn't matter what my macros are as long as I consume less calories than I burn daily. Yet, I consume close to my previous garbage diet calories and I lose about 2-3lbs/week due to my high fat/moderate protein/very low carb ( Go figure, it appears that caloric energy balance isn't the only factor.

From someone who's been doing keto for several years now. A: Pre-Keto, odds are you we underestimating how many calories you were eating. Unless you were tracking every single thing you ate, there is a high probability you just didn't realize how many calories you were consuming. B: It is super hard to over eat on Keto. It is possible, take lots of liquid calories in (heavy cream can do this easily!), and there are s…

It's definitely hard to eat too much when you aren't taking in starchy carbs or sugars.

Made a vichyssoise the first time a few days ago (subbed most of the potato with cauliflower and parsnips) and have to say it was about the most filling soup I've ever eaten... had trouble eating the 2-cups I usually do for a "serving" of soup.

If going a more Paleo inspired route, fruit is probably the most easy to over do. I try to stay under a GL of 100/day, being diabetic it's risky for me to stay in keto too much, ketoacidosis is not fun at all.

You've gone all out for some high end luxury soups :)They sound delicious. But you can make nutripus delicious soups without spending that kind of money, for very little money in fact. Cooking can be done coat effectively but you have to remember the objective is not Masterchef finesesse.

I did home economics in school and I agree everyone should do some.

How carefully were you tracking calorie intake? It's notoriously difficult and I simply don't believe you ate 1500-2000 calories at 340lbs and didn't lose weight (not that you need to convince me). In any case, congrats on the achievement!

There are lab rats (whose hormones/genetics have been fucked with) that can literally die of starvation while remaining nearly spherical with excess fat. When their food is removed, their bodies ignore the stored fat and strictly cannibalize muscle and other tissues until the rat dies.

Being fat is much more complicated than calories in minus calories burned.

From the article you're writing a comment to: > A given person, in 2006, eating the same amount of calories, taking in the same quantities of macronutrients like protein and fat, and exercising the same amount as a person of the same age did in 1988 would have a BMI that was about 2.3 points higher.

They didn't control the energy expenditure to any meaningful degree. Essentially worthless.

The point of the study, from what I can tell, was to show that calories+macronutrients+exercise, the three main current targets of anti-obesity intervention, fail to account for a large portion of observed population-scale changes. They aren't arguing generally against total energy balance being involved, only that those three quantities don't constitute a sufficient measure of total energy balance. The implication would be that there are likely other sources of variation, e.g. changes in digestion, metabolism, etc. (the study doesn't really go out on a limb and speculate on that part).

Humans aren't the only ones gaining weight, animals are too:

What you're talking about is macronutrients (amount of sugars vs. saturated fats vs. protein, etc.), and if the study is correct, it specifically claims that changes in macronutrients, even when coupled with a measure of total calories consumed and levels of exercise, fail to fully account for the observed increase in obesity rates.
