A new study published in the Journal of Clinical Endocrinology & Metabolism just confirmed something many in the low-carb and carnivore communities have been saying for years: eating more fat and fewer carbs is better for your health. Researchers followed 731 Japanese people with type 2 diabetes for about 7.5 years. They wanted to see how different diets affected heart disease and overall risk of death. What they found should make anyone still pushing a high-carb, low-fat diet take a second look.
The study showed that people who ate a higher proportion of their calories from carbohydrates had a greater risk of heart problems and even death.
On the flip side, those who ate more fat—especially animal fats—had better health outcomes. In fact, the study found a strong link between more saturated fat intake and a lower chance of getting heart disease or dying from any cause. That’s the complete opposite of what many nutrition guidelines have been saying for decades.

For years, we’ve been told that fat, especially animal fat, is bad for the heart. But what if they lied or misappropriated the truth to sell goods.
This study joins a growing body of research proving that carbohydrates—not fat—are the real problem. When you eat a lot of carbs, especially processed ones, your blood sugar spikes, leading to insulin resistance and inflammation. Over time, these insulin spikes leads to diabetes, heart disease, and other serious health issues. But when you cut down on carbs and replace them with healthy fats and protein, your body runs on fat for fuel instead of sugar.
Running on ketones helps to keep blood sugar stable and reduces inflammation, helping to prevent chronic disease.
The carnivore diet, which is based on eating only animal foods like meat, eggs, and dairy, aligns perfectly with these findings. It eliminates the high-carb foods that contribute to disease and focuses on nutrient-dense animal products. People following a carnivore or high-fat, low-carb diet often report weight loss, better blood sugar control, and improved heart health. This study backs up what many have experienced firsthand.
Some might argue that this research only applies to people with type 2 diabetes, but it actually has bigger implications. If people who already have blood sugar issues see huge benefits from lowering carbs and increasing fat, it makes sense that avoiding excessive carbs is a smart choice for preventing these problems in the first place.
Another key takeaway from this study is that the type of fat you eat matters. The people who ate more animal-derived fats and proteins had better health outcomes than those who got their fats from other sources. This means natural, whole foods like beef, pork, eggs, and dairy are likely much better for your body than processed vegetable oils and plant-based fats.
This is yet another nail in the coffin for the outdated advice that tells people to avoid red meat and animal fat.

At this point, the evidence is becoming impossible to ignore. Low-carb, high-fat diets aren’t just another health trend—they’re backed by real science. This study adds to a growing pile of research showing that cutting carbs and eating more natural fats is a smarter way to eat. Whether you follow a strict carnivore diet or just focus on eating more animal-based foods and fewer processed carbs, your body will thank you.
For those still clinging to the old-school low-fat, high-carb diet model, it might be time to rethink what actually makes sense for long-term health.
The data is clear: high-carb diets come with serious risks, while diets higher in fat—especially from animal sources—offer real protection. If you want to take charge of your health, embracing a diet rich in meat, eggs, and healthy fats might just be the best decision you ever make.
