Keep desired items within reach and unwanted ones out of sight — no need to resist temptation on the spot
Grade BMedium benefitTimeFreeLittle timeNo willpower
When items are physically farther away, people tend to consume less of them. Placing snacks at a distance noticeably cuts down on intake — this effect is of moderate strength. Limiting the number of available choices also leads to a marked drop in consumption. These strategies require no willpower on your part; you can arrange everything in just a few minutes.
- Cost
- No cost involved; takes just a few minutes to set up. Simply move your phone to another room and lay out books and a computer on the desk.
- Benefit
- A Cochrane review encompassing 24 randomized trials supports these findings. Moving food farther away reduces consumption, with a standardized mean difference of −0.60 (95% CI −0.84 to −0.36; based on 12 studies involving 1,098 participants; evidence of low certainty). Limiting food options yields an even stronger effect, with a standardized mean difference of −1.13 (95% CI −1.90 to −0.37; based on 3 studies involving 154 participants; evidence of low certainty). Regression analysis confirms that both distance and fewer choices amplify the effect.
- Notes
- This B rating stems from the fact that all 24 studies included in the review focused on food only; none examined alcohol or tobacco. Additionally, 14 of those studies were conducted in laboratory settings and originated from high-income countries. Applying these same principles to phones and video games is a logical extrapolation, as no direct trials exist on this specific use case. One study directly examined the effect of removing phones from one’s line of sight; see Section 3, Item 1 for details (turning off nonessential notifications and keeping phones out of sight while working).
