Adherence
Lowering the price of food, particularly through temporary promotions and quantity discounts, significantly increases energy intake and consumption volume, especially among low-income consumers and children.
Be aware that sales, coupons, and bulk packaging are designed to increase your total food intake, not just save you money. If you buy a large package or use a coupon, you are likely to eat more, even if you are not hungry. To counteract this, buy smaller portions or dispose of excess food immediately after purchase.
GoodSupportsHIGH confidence
Overall, all the studies reviewed here clearly show that pricing is one of the strongest – if not the strongest – marketing factors predicting increased energy intake and obesity, and this is why lower-income consumers are predominantly affected by these conditions.
Why this rating
Supported by multiple randomized controlled trials, longitudinal field experiments, and econometric studies.
