Here's the Biology","\u003Cp style=\"margin:0 0 18px;\">A pastry shaped like a breadstick, a meter-class length, and a price tag around $1.50: the \u003Cstrong>long egg tart\u003C\u002Fstrong> has become the viral food of the season. Bakeries, coffee shops, and street stalls all sell it — some stores limit purchases, some lines run for hours, and the 60-centimeter tart has turned into a social-media badge: the photo comes first, the eating second. Fans call it a photo-op miracle. Then comes the confession everyone seems to share: \u003Ci>\"I got through one-third and it was too rich — I had to throw it away.\"\u003C\u002Fi>\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">A single long egg tart can pack \u003Cstrong>over 1,000 calories\u003C\u002Fstrong> — close to the energy of an entire meal, or two. Why is something so irresistible also so hard to finish? The answer is not marketing.

Food scientists have shown that sugar-fat mixtures sit at what is sometimes called the \u003Cstrong>\"bliss point\"\u003C\u002Fstrong> — a ratio of sugar, fat, and salt that maximizes reward.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">Fat delivers rich mouthfeel and slow-burning energy; sugar delivers fast sweetness and a quick signal to the brain's reward circuits. Together they produce a pleasure response neither can achieve alone. That is why \"crust plus filling\" foods — pizza, croissants, egg tarts — have a near-universal pull, and why the viral tart's thinner crust and bigger filling is precisely the direction consumers demanded.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cimg src=\"\u002Fattachment\u002F20260927\u002F42c736f3674d496ba86866581c3b917c.png\" alt=\"Long egg tart cross-section showing flaky butter layers and thick custard filling\">\u003C\u002Fp>\n\u003Ch2 style=\"color:#111;font-size:21px;line-height:1.4;margin:28px 0 12px;\">\u003Cstrong>Why You Get \"Tired\" of It After a Third\u003C\u002Fstrong>\u003C\u002Fh2>\n\u003Cp style=\"margin:0 0 18px;\">Feeling sick of it is not a character flaw; it is a set of biological brakes.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cstrong>Fat slows digestion.\u003C\u002Fstrong> Fats move slowly through the stomach, delaying gastric emptying. The presence of fat in the gut triggers satiety hormones such as \u003Cstrong>cholecystokinin (CCK)\u003C\u002Fstrong>, which signals fullness and, at high levels, a sense of heaviness.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cstrong>Sugar-fat meals are energy-dense but not volume-dense.\u003C\u002Fstrong> 1,000 calories in a custard pastry occupies far less stomach space than 1,000 calories of vegetables. Your fullness signals are volume-based, so a small, dense pastry can deliver a huge calorie load before your stomach \"registers\" it — and the nausea often arrives right after the reward fades.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cstrong>Sensory-specific satiety kicks in.\u003C\u002Fstrong> Pleasure from a food drops as you keep eating it — especially for foods that are monotonous in taste and texture. A long egg tart is one flavor, one texture, repeated for 60 cm.
