00:00I hope you save room for dessert.
00:01What the hell is that supposed to mean?
00:11For dessert, I'll have dinner again.
00:20So the more you eat a food that you really like at the beginning of the meal,
00:25after a while you'll start to find it less pleasant.
00:29And that means that the reward value of that food, the hedonic assessment of that food,
00:34is less pleasant.
00:36And then if someone comes along and offers you a different food,
00:40perhaps a dessert, then you will have room for dessert.
00:44Because you may have switched off of the hedonic assessment of the savoury food.
00:55As omnivores, we have to eat a variety of foods.
01:03So at one level, when one food is consumed during a meal,
01:07we switch off of that food and we start to seek and search out for other foods.
01:12So at one level, sensory specific satiety is considered to be a driver of variety
01:19to ensure that omnivores eat a lot of different foods.
01:25So
01:45the scientific studies conducted by Barbara Rawls shows very clearly
01:49that if you feed someone a simple, plain food as a first course,
01:54and then offer a second course, they will eat modestly.
01:58But if you have one course followed by a different course followed by another course,
02:03or you have access to a variety of foods at one sitting,
02:07then this will encourage overconsumption.
02:12In today's society, we have so much access to very cheap foods.
02:18We have foods delivered to our door.
02:20And there's now a mismatch between the amount of energy that we need to expend
02:25to get those foods. We're not hunting and gathering anymore.
02:28So there's definitely a sense in which our sensory specific satiety
02:32and drive for variety might actually be counterproductive
02:37in such an obesogenic environment.
02:39So the solution is to eat simply and modestly.
02:45And it's good to eat a variety, but smaller portion sizes
02:49and to have a strategy and a plan in mind.
