The Claim
In healthy adults following a self-selected low-carbohydrate, high-fat (LCHF) diet for at least six months, saturated fat intake is strongly associated with significantly higher total and LDL cholesterol levels, with saturated fatty acids being the strongest positive predictor and monounsaturated fatty acids a negative predictor, explaining 40% of the variance in cholesterol levels.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you eat a lot of fat and very few carbs for half a year or more, the saturated fats in your diet tend to raise your bad cholesterol, while the monounsaturated fats might lower it — together, these fats explain about 40% of why your cholesterol levels go up or down.

What the research says
1 studyStudy: Habitual low carbohydrate high fat diet compared with omnivorous, vegan, and vegetarian diets
This study looked at people who ate low-carb, high-fat diets for months and found that the more saturated fat they ate, the higher their 'bad' cholesterol went—and the more healthy fats they ate, the lower it went. This matches exactly what the claim says.
