Teens using AI meal plans could be eating too few calories — equivalent to skipping a meal

https://www.frontiersin.org/news/2026/03/12/teens-ai-meal-plans-too-few-calories-frontiers-in-nutrition

Can AI tools make meal plans that help us lose weight the right way? In a new study, a team of researchers compared AI’s meal planning abilities to those of a dietician. The results showed that AI-made meal plans – when compared to dietician plans – severely undercalculated the needed amount of calories and macronutrients like carbs and overemphasized other macronutrients like proteins and lipids. The team cautioned that teens should not solely rely on AI to make meal plans for weight loss, saying that the consistent deviation of five different AI models from nutritional guidelines recommended by health organizations could have negative effects on growing bodies.

I wonder how much of this comes from dieting nonsense on Reddit and blogs.

Tollana1234567@lemmy.today · 4 pts · 158d

intermittent fasting seems to the current trend, considering how body image/gym obssesed people are on reddit subs. r/gym will ban you for even mentioning "peds' in any form, they dont want get called out for cheating and using shortcuts for thier weight loss.

Well, since over 40% of the world is considered overweight … maybe we should have fewer calories.

Tollana1234567@lemmy.today · 3 pts · 158d

its actually biologically dangerous to lose a lot of weight at once if you way hundreds of lbs over your limit. its the same for pet dogs and cats.

CheeseNoodle@lemmy.world · 1 pts · 157d

I've been thinking about this lately in regards to how shitty food is getting, with shrinkflation a lot of stuff now has smaller portions sizes but the calorie count usually remains the same, presumably due to adding more sugar to mask the taste of replacing ingrediants with cheaper alternatives, fresh produce isn't spared either as most meat and vegetables turn a lot sooner and are sometimes already beginning to turn the same day you buy them. The result is a decreasing ability to have more than a day or twos worth of fresh ingrediants on hand and frozen food (or worse) just getting simultaniously less health and less filling.

If that 60% of people who aren’t weren’t occupied with working hard not to starve they might take offense to your use of “we” (Satire)

Iconoclast@feddit.uk · 5 pts · 158d (9 replies)

Food isn't expensive - high quality food is. Junk is cheap which is why obesity is especially issue with low-income families. Nobody is starving.

webghost0101@sopuli.xyz · 2 pts · 158d

I am not talking about people who have easy acces to processed foods.

I don’t have exact stats nor know how big% of the world that is but people going to bed hungry and being underweight is absolutely still happening.

ExcessShiv@lemmy.dbzer0.com · 1 pts · 158d (7 replies)

I don't know where you live, but where I live junk is stupid fucking expensive compared to veggies, and an increasing number of people are still overweight. A single 300-350g frozen pizza will set you back at least 6EUR, I can easily buy fresh veggies for a meal to feed a family of 4 people for 12EUR, less if you try to save money. I simply don't buy in to the whole cost premise being the reason.

nyan@lemmy.cafe · 7 pts · 158d

Time and energy to prep meals is also a cost. I don't know how it is in Europe, but in North America, the poor-but-employed segment of the population is often working multiple minimum wage jobs to stay afloat. Even if they know how to cook and have the tools to do so, they may be too tired when they get home to do more than pop a pizza in the oven.

Iconoclast@feddit.uk · 5 pts · 158d (5 replies)

3 euros worth of vegetables almost definitely doesn't have the same calorie content than 3 euros worth of any junk food. This is true independent of where you live in the western world.

ExcessShiv@lemmy.dbzer0.com · -1 pts · 158d (4 replies)

Exactly, so obesity is not a cost issue

Iconoclast@feddit.uk · 2 pts · 158d

Yeah because poor people are famously known for switching to home cooked vegan meals which naturally decreases their calorie intake.

org@lemmy.org · -5 pts · 159d

Maybe they should eat the other 40%. ;)

socphoenix@lemmy.world · -3 pts · 159d (9 replies)

Losing weight too fast can destroy your organs, so this is a very stupid take.

Iconoclast@feddit.uk · 22 pts · 158d (2 replies)

Lemmy logic on full display again. A user merely mentions that almost half the world's population is overweight and could stand to lose some weight - and the response is "stupid take, losing weight too fast can destroy your organs."

And people are actually upvoting that. Great. Just great. Good job, guys.

fallaciousBasis@lemmy.world · 2 pts · 157d

Lemmy is just Reddit going full reeeeeeetard.

Tollana1234567@lemmy.today · -2 pts · 158d

and think he has more downvotes than upvotes.

entropiclyclaude@lemmy.wtf · 5 pts · 158d

Slowly eating fewer calories isn’t going to cause this. Quit overreacting

fallaciousBasis@lemmy.world · 1 pts · 157d

It seems you're confusing starvation being bad with dieting being good.

stoly@lemmy.world · 1 pts · 159d (1 reply)

So not feed the troll

fallaciousBasis@lemmy.world · 3 pts · 157d

Bro... you don't want the troll to get organ failure.

Tollana1234567@lemmy.today · 0 pts · 157d

seems the original commentor is downvoting us multiple times, with different ACCTS with bots.

org@lemmy.org · -10 pts · 159d

It’s a fine take. You just dislike AI and you need dopamine from online arguing.

sturmblast@lemmy.world · 9 pts · 158d

..... this is a fake problem

TheTempest@lemmy.world · 3 pts · 157d

If they live in America skipping meals here and there might not be a bad thing tbh

Can AI tools make meal plans that help us lose weight the right way?

No. Don't use it for that.

What's the needed amount of carbs? Proteins and fats are essential nutrients. Carbohydrates are not.

XLE@piefed.social · 5 pts · 158d

Just realized you're the same person who was doing a weird defense of AI companies generating CSAM and revenge porn the other day... Now you're taking AI's side by Just Asking Questions about nutrition.

Do you actually have an issue with the article, or is this just a knee-jerk defense of the companies?

Carbohydrates are required to break down proteins and fats. They're very much an essential nutrient, just not in the quantities the old food pyramid would have you believe.

If carbs weren't essential, a pure protein and fat diet wouldn't outright kill you from kidney failure.

xep@discuss.online · 8 pts · 158d (3 replies)

You're confidently incorrect. You don't need to eat carbohydrates to break down fat and protein, and a diet consisting of healthy proteins and fat has not been proven to cause kidney failure.

fallaciousBasis@lemmy.world · 1 pts · 157d (2 replies)

Actually.... High protein diets can cause de novo kidney disease. De novo means it's causal, from the new. Out of nowhere! Not even with pre-existing conditions, although if you have those pre-existing conditions then this applies even more.

I'm not aware of any direct links to kidney disease from dietary fat. But extremely high protein has strong causal links to de novo (along with comorbidities) kidney disease.

High protein diets can cause de novo kidney disease

I'm not suggesting that you overdose on protein, if you're referring to rabbit starvation. If you aren't, would you care to provide more information?

fallaciousBasis@lemmy.world · 0 pts · 153d

Here's my thoughts.

Hyperfiltration exhausts (overworks, think of it like high blood pressure?) the kidneys.

This causes acceleration and perhaps inducing(de novo) disease.

I know the evidence is quite weak. But there's so many studies that show it's making it worse for people with even minor kidney impairment and it just gets worse as it gets worse showing an accelerated momentum effect.

Iconoclast@feddit.uk · 6 pts · 158d (4 replies)

Your body can synthesize all the carbohydrates it needs through gluconeogenesis. There are no "essential carbs" the way there are essential fatty acids and amino acids. You can absolutely live on a diet of just fats and protein - and plenty of people do. The Inuit mostly did, and so do folks on carnivore diets today.

It might not be the healthiest long-term option, but it won't kill you from a lack of carbs. You're probably thinking of "rabbit starvation" which happens when you eat too much protein and not enough fat.

Braindead comment.

I say that because brains demand carbs to function optimally.

Sure. You're gonna survive. But you'll have brainfog and your red blood cells aren't gonna be happy either.

Plus you need micros....

Don't get me twisted. IMO, you gotta balance your diet. Extremes aren't doing you any favors.

Your position isn't an informed one. A quick pubmed search on ketogenic diets and cognition shows improved and protective benefits.

fallaciousBasis@lemmy.world · -1 pts · 153d

Lol...

Fine print:

In studies in epileptics and others with cognitive impairments... Not normal healthy cohorts.

xep@discuss.online · 2 pts · 157d

The human brain can use ketones for its requirements, and your body is able to produce all the carbohydrates it needs via gluconeogenesis. Including the needs of all your erythrocytes.
