The Diet Hall of Shame

Every fad diet in history fails the same two-question exam. One: is there basic science behind it? Two: does it produce results people actually keep? Decade after decade, costume after costume, the answers come back no and no. Let’s tour the museum.

First, two famous exhibits that deserve nuance.

Fasting, done wrong. Fasting can work — it’s simply one way of arranging a caloric deficit. But the popular version often goes like this: keep breakfast, white-knuckle through the day feeling virtuous, then demolish the kitchen at 10 p.m. Congratulations — you’ve invented the all-day appetizer for a nightly binge. The clock didn’t fail you; the deficit never existed.

Keto. The ketogenic diet is a genuine medical tool — developed in the 1920s for epilepsy, and still used in neurological care today. That’s its real niche, and it’s a respectable one. As a general weight-loss plan? Nothing magical: when it works, it works through the same old deficit. And many online versions lean hard on butter, bacon, and saturated fat — re-read lesson four and wince.

The hall of shame

Now the main gallery:

• The moon diet — fast according to lunar phases. The moon moves oceans. It does not move your fat cells.
• The liquid diet — all the hunger, none of the chewing.
• Detox teas — your liver and kidneys detox you every day, free of charge. The teas mostly make you poop and pay.
• The cotton-ball diet — swallowing cotton to feel full. Genuinely dangerous: intestines are not laundry hampers.
• The tapeworm diet — paying money to acquire a parasite. Yes, this was sold. Yes, on purpose.
• The soap diet — soap, but as a food. History is undefeated.
• The drinking man’s diet — a 1960s bestseller built on martinis and steak. The hangover outlived the results.
• Multi-day extreme fasting — muscle loss, misery, and a rebound with your name on it.

Funny? Absolutely. But firm: some of these are merely useless, and some are genuinely dangerous. None of them taught anyone how to eat for the rest of their life — which is the only exam that counts.

You now know more than every diet in this museum: energy balance, protein, fiber, a sane deficit, and muscle as your engine. That’s the whole secret. It was never hiding.

The takeaway: if a diet has no basic science and no long-term results, it belongs in a museum — not in your kitchen.

That wraps the Nutrition track. Next stop: the Exercise track, where we build the engine.
