I have eaten 4000 calories of fat in an afternoon, mostly in cream and butter as part of a giant poundcake trifle [0]. I didn&#x27;t throw up but I really regretted it all evening. This was at a time when I was very active and eating around 7000 calories a day.<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Trifle" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Trifle</a>
