The Nutrition Grouch

The Major Mistake Nutrition Education Keeps Making

Todd Weber, PhD Episode 30

We keep treating nutrition and weight management as a logic and reasoning problem when it is not.  The math is simple, eat fewer calories than you burn, and you'll lose weight.  If you know the number of calories in a food, you'll make the decision to eat it or not eat it to stay within your daily calorie budget.

Yes, weight loss is a calories in/calories out math equation, but it is also so much more than that.  We need to spend more time looking at how food decisions are made and how to better control our food environment.

The nutrition field seems to think that we can "educate" our way out of the obesity epidemic.  That if people had the "right" information, they would make better eating decisions.  But eating decisions are not born out of logic and reasoning.

Eating decisions are controlled more by our emotions (whether conscious or subconscious), the food environment, and the pleasure and reward we get from eating sugar, fat, and/or salt, than by knowing what is "good" for us or "bad" for us.

We're not going to out reason, or outwit, manipulate or hack our physiology to decrease our hunger or increase our metabolism through various diet strategies.  We've been there, tried that (food doesn't work but medicine can).

Nutrition does not exist in a vacuum, separate from all the other parts of peoples' lives.  We need to take a more wholistic approach at looking at the individual's emotions and stressors that lead to food decisions.  Rather than focusing on the food, we need to focus on the individual.

We also need to find ways to "replace" the pleasure people are getting from food by engineering other daily pleasure inducing opportunities into their lives whether that be phoning a friend, watching Netflix, or going for a walk.
