100% guaranteed you won't watch the whole 2 parts but there are literally hundreds of studies linked to in this video of part I and part II that prove Saturated Fats cause heart disease
They are all RCT's and meta analysis
"Literally" hundreds? There goes all of your credibility.
1. There are only four studies on saturated fat linked to part I, four, not literally hundreds. And there are none linked to part II, zero.
2. None of those four even claim to "prove that saturated fats cause heart disease" as you claimed, and none of them were done in the context of a keto diet. What they claim is that replacing saturated fats with vegetable oils may be more heart healthy. That might indeed be "better" in people who consume saturated fats along with a high carbohydrate intake (excessive carbs are the problem), but it's definitely not true for people on a very low carb, ketogenic diet.
More recent studies show saturated fats are not only harmless, but beneficial too.
CVD = Cardiovascular Disease
"Numerous meta-analyses and systematic reviews of both the historical and current literature reveals that the diet-heart hypothesis was not, and still is not, supported by the evidence. There appears to be no consistent benefit to all-cause or CVD mortality from the reduction of dietary saturated fat. Further, saturated fat has been shown in some cases to have an inverse relationship with obesity-related type 2 diabetes. Rather than focus on a single nutrient, the overall diet quality and elimination of processed foods, including simple carbohydrates, would likely do more to improve CVD and overall health. It is in the best interest of the American public to clarify dietary guidelines to recognize that dietary saturated fat is not the villain we once thought it was."https://pubmed.ncbi.nlm.nih.gov/30084105/"High carbohydrate intake was associated with higher risk of total mortality, whereas total fat and individual types of fat were related to lower total mortality. Total fat and types of fat were not associated with cardiovascular disease, myocardial infarction, or cardiovascular disease mortality, whereas saturated fat had an inverse association with stroke. Global dietary guidelines should be reconsidered in light of these findings."https://pubmed.ncbi.nlm.nih.gov/28864332/"Canada’s Heart and Stroke Foundation recently removed any specific limitation on saturated fat, stating instead that their dietary guidelines do 'not include a threshold or limit for saturated fat and instead focus on a healthy balanced dietary pattern'"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5577766/
