Diets work best when compensatory intentions are not acceptable from the start. The team’s findings were published in the journal Appetite. The study was made up of 42 women participants and examined how dieters dealt with temptations.
The McGill team created a scenario in which dieters were given the choice of either eating a tempting cookie or an untempting cookie. Then they were asked to report any compensatory intentions they formed while deciding which cookie they wanted to eat. When dieters were tempted by a high calorie food they formed plans to make up for eating it such as; “I’ll skip dinner”; “I’ll cut back later”. These rationalizations or compensatory intentions were formed, so that they could eat the cookie and not feel guilty about breaking their diet.
“There are many ways in which dieters manage temptation, said Ilana Kronick, McGill Ph.D. student. “Typically, they will either resist it with an increase in willpower or give-in by adopting defeatist or rebellious attitudes”. A third option is to give in to temptation with the promise to make up for it later. Dieters who use this type of thinking believe in the ability to compensate for indulgence with later behaviors, such as skipping dinner, but this doesn’t happen.
According to Knäuper, people should not form compensatory intentions because they lead to failure. “Refrain from indulging in compensatory intentions so that you may indulge, because it rarely balances out in the end as you had planned.”
