In addition to the effects of the health warnings on public acceptance of the product, olestra might not have lived up to consumer expectations of speedy results. If consumers believed they could eat more to compensate for the fat calories "saved", olestra would not be an effective way to improve overall diet. The manufacturers claim that the authentic taste and feel of olestra offsets this tendency, and some studies have shown that people who consume foods with olestra don't eat more to offset the loss in calories. P&G conducted publicity campaigns to highlight olestra's benefits, including working directly with the health-care community.
