I would be interested to see that same data cross-referenced with rates of:
- Increase/decrease in portion sizes at restaurants and/or grocery stores.
- Advertising for food products and/or advertising for food products to kids.
- Price per calorie of food (broken down by restaurants vs. grocery stores).
Not to claim that we shouldn’t take responsibility for our own actions, but since I started measuring what I ate, I’ve discovered that calorie counts in restaurant food are way higher than I thought, and appear to have risen substantially over the last 20 years. It makes sense since the marginal cost of serving more food is a small for a restaurant, yet popular with customers.
Even though I’m not obese, it’s generally a good idea for me to eat no more than half of any dish I’m served in a restaurant.
