After adjustment for trend and seasonal effects, the Monday following spring time changes was associated with a 24% increase in daily AMI counts (p=0.011), and the Tuesday following fall changes was conversely associated with a 21% reduction (p=0.044). No other weekdays in the weeks following DST changes demonstrated significant associations.

You are seriously misinterpreting the medical evidence of the harm caused by the spring DST shift.
Despite common opinion that the DST spring shift leads to the relatively inconsequential loss of 1 h of sleep on the same night, increased sleep fragmentation and sleep latency present a cumulative effect of sleep loss at least across the following week, possibly longer . . . . Janszky and Ljung first reported a higher incidence of AMI following the spring DST shift, which was more pronounced in women. We reviewed the available literature on this association [10], and found another six studies, four conducted in Europe and two in the United States, accounting for a total of 87,994 cases. Although there were differences among each other, they all supported the existence of an association between DST and the risk of AMI, particularly after the spring DST transition, with an increase ranging from 4 to 29%. In particular, three studies report a higher incidence on Monday, and only four provide an analysis by separating subgroups by gender

As to eating a single triple bacon cheeseburger with extra cheese being a more significant risk - nonsense. Even if you follow traditional notions of cholesterol consumed => serum cholesterol, the risk from a single triple bacon cheeseburger with extra chees is insignificant. In addition, there is a growing body of evidence that serum cholesterol is not directly linked to consumption of cholesterol. Many people who eat a ketogenic diet (generally more than 50% fat) have significantly lower cholesterol than those who eat high carbohydrate diets.
