@davidludwigmd Except, when you completely control the sugar level they still get fat in relation to increasing fat in the diet up to about 60% by calories. see https://t.co/elKzw0Td7G a study that used 30 diets controlled for macronutrient contents which they mysteriously forgot to cite.

AI synopsis
What people are saying
The discussions show active engagement with details from the research, referencing the specific composition of diets that impact weight gain in mice, such as the percentage of fat versus carbohydrates. Phrases like 'this is just the tip of the iceberg' and 'the best-controlled studies support this' indicate a tone of excitement and urgency for further exploration of the topic, highlighting a strong belief in the significance of these findings.
Most discussions affirm the findings of the article, with many users corroborating the role of dietary fat in energy regulation and adiposity.
Participants express significant curiosity about the implications of the study, as indicated by frequent references and requests for related research.
Many commenters engage with the content by discussing specifics of diet formulations and their observed effects in both animal studies and their relevance to human diets.
The community perceives the publication's findings as having noteworthy implications for understanding dietary impacts on obesity.
Abstract in brief
- The study investigated how different macronutrients, particularly fats, proteins, and carbohydrates, affect energy intake and obesity in mice.
- Increased dietary fat was the only macronutrient linked to higher energy consumption and increased body fat, while proteins and carbohydrates did not show the same effect.
- The research found that this increase in fat intake influenced certain brain pathways related to appetite regulation, suggesting that fat triggers a stronger response in the body than sugars or proteins.

@garytaubes I am wondering if you read our paper in Cell metabolism in 2018 showing that when you completely control the sugar levels it's still increasing fat in the diet that makes mice fat. 30 diets, 5 strains, >1000 mice. https://t.co/elKzw0Td7G
This echoes the findings of @JohnSpeakman4, whose large, detailed study reported that dietary fat, but not carbohydrate/sugar, is the primary macronutrient that drives body fat gain in mice. https://t.co/lrlWBlF83K
Interestingly, sucrose (which is a 50:50 glucose:fructose disaccharide) was not very fattening and did not lead to metabolic problems, consistent with previous findings like those from @johnspeakman4 group. https://t.co/lrlWBlF83K
@ggkuhnle It's worth noting that solid sugars aren't very fattening in rodents and don't seem to have much impact on adiposity in human RCTs. Liquid sugars appear to be more fattening. https://t.co/VTsObeSwdX

@richcollins I use the term "refined high-fat diets" in an attempt to communicate that this is a specific type of pelleted rodent diet that's high in fat. That said, the fat itself does play an important causal role in the fattening effect. https://t.co/VTsObeSwdX

@tednaiman @realDaveFeldman If the animal is a mouse then the answer is no. To make a mouse obese you need to feed it a diet where about 40-60% of calories come from fat, 20% from protein and the balance comes from carbs.

@deirdre_tobias Also, how well controlled a trial is for the fat/CHO swap in inversely related to its duration. As you know, it's hard to tightly control variables in long-term diet trials. The best controlled of all are the rodent studies, especially this one. https://t.co/lrlWBlo51K

@garytaubes @whsource @KevinH_PhD That is simply not true. C57BL/6 mice get fat on high fat diet but stay slim on a high carb diet because on high carbs they eat less food/energy. They are relatively food restricted and dont get fat (Hu et al 2018 Cell metabolism https://t.co/elKzw0Td7G
