> Making password entry difficult is like attempting weight loss by eating bland food. It's not the flavour that makes you fat.
Big side-tangent, but amusingly enough, one modern view on the etiology of metabolic syndrome is that your brain tracks satiety for different nutrient classes separately; so foods that are "tasty" in the sense of containing many different nutrient-signals (sugar, salt, fat, acid, etc.) take larger quantities of food to signal fullness (something something liver metabolism is a rate-limited queue); so if you start off hungry and eat such foods until you "feel full", you will have eaten more of them than you "should have", to the point of eventually doing excitotoxic things to your leptin receptors, inducing leptin resistance and making you feel hungry more often.
Which is to say, it's not flavor that makes you fat, but rather flavors, plural. ;)
The advice of the scientists who subscribe to this hypothesis is that you don't have to eat bland food; you just have to eat monotonous food (food only containing one primary nutrient-signal), and you'll feel full with less of it. When you sit down for a meal, eat all meat, or all bread, or all green leafy vegetables. Balance your diet by having something different each meal, not by combining foods in a single meal. Avoid foods that are themselves "combinations", like pizza. Avoid adding a secondary nutrient-signal to something to "amp up" the taste, like adding sugary+oily dressing to a mineral-y salad. Just choose foods that already taste good to you without any "amping up", and eat those, by themseleves.
This is, after all, the real "paleo diet": when animals kill prey, they eat just meat for a meal. When they find fruit, they eat just fruit for a meal. They don't bring them together to eat them all at once.
(Whatever you think of the hypothesis, studies have been done which confirm the advice: eating monotonously per meal, makes you feel full after less food intake. You hit a wall with a kind of "tired/bored of eating this, disgusted by the idea of eating more" feeling, which makes you lose the rest of your appetite. That's your body's nutrient-satiety mechanism kicking in correctly.)
