The short version
Food cues and cravings reliably predict eating. Visual cues, like pictures and videos of food, have about as much pull as real food.
Rigid, all-or-nothing control of eating is linked to more binge eating. Flexible control is linked to less, but "flexible" rules can quietly turn rigid.
Eating while distracted increases intake at that meal and, even more, at later meals.
If-then plans work better for adding something than for cutting something out. The plans that last are the ones the client writes.
Cues are powerful, and that isn't a character flaw
The smell from a bakery, a candy display at the register, a commercial during an evening show: these cues set off wanting before a person has decided anything. Boswell and Kober (2016) pooled 45 published reports covering 3,292 participants. Food cue reactivity and craving predicted later eating with a medium effect (r = 0.33). Visual cues had about the same effect as real food exposure and a stronger one than smells.
This is useful to share with clients, because it moves the problem out of willpower and into the environment. Responding to cues is how human learning works. It's not a sign of weakness, and the food isn't the enemy.
The phrase "rules of disengagement" comes from David Kessler's 2009 book The End of Overeating, which has a chapter by that title in its section on treatment. The idea of planning ahead for cues holds up. What needs updating is the assumption that the answer is a set of firm rules.
Rigid rules versus flexible plans
Westenhöfer, Stunkard, and Pudel (1999) developed questionnaire measures of 2 kinds of eating control, using data from more than 54,000 people in a weight-reduction program and a random sample of 1,838 adults in West Germany. Rigid control (all-or-nothing rules, no exceptions) was linked to more frequent and more severe binge eating and more disinhibited eating. Flexible control (a more graded approach that allows exceptions) was linked to less frequent and less severe binge eating. These are associations, not proof of cause.
There's a catch. Tylka, Calogero, and Daníelsdóttir (2015) found that flexible control overlapped heavily with rigid control in a sample of 382 adults. A plan that starts flexible ("I'll mostly skip dessert on weeknights") can harden into a rule that feels broken by one cookie. The problem usually isn't having a plan. It's a plan with no room for exceptions, and the guilt that comes with "breaking" it.
Distraction and attention
The common "no eating in front of the TV" rule has real evidence behind it, though the reason is worth explaining. Robinson et al. (2013) reviewed 24 experimental studies. Eating while distracted produced a moderate increase in intake at that meal (standardized mean difference 0.39) and a larger increase at later meals (0.76). Making the memory of a meal stronger reduced later intake. One likely reason is that distraction weakens the memory of having eaten, and that memory matters for later eating.
That's an argument for paying attention, not for banning screens. A client who loves eating dinner with a show on doesn't need a rule; they might experiment with the first few bites before pressing play.
If-then plans
An if-then plan (an implementation intention) links a specific situation to a specific response: "If X happens, then I will do Y." Adriaanse et al. (2011) pooled 23 studies of if-then plans for eating. They worked well for adding healthy foods (d = 0.51) and less well for reducing less healthy eating (d = 0.29). The authors note some effects may be inflated by weak control conditions.
The practical lesson: plans aimed at adding or substituting tend to work better than plans aimed at avoiding.
Using it with clients
Start by mapping the client's own cues, not by handing over a list. Use MI to draw out what they already notice, then let them write the plan in their own words.
"When do you find yourself eating when you hadn't planned to?"
"What's going on around you in those moments?"
"If you could set things up ahead of time so that moment goes more the way you'd like, what might that look like?"
"It sounds like when the plan slips once, it feels like you've blown the whole week."
Help the client phrase plans around adding or substituting. "If I get home hungry at 6, then I'll have the snack I packed before I start cooking" tends to work better than "I won't snack before dinner." Build flexibility in from the start: plans that apply "most days" or that name the exceptions ahead of time.
Listen for signs a plan is turning rigid: guilt, "always" and "never" language, or talk of having "ruined" a day. When you hear it, reflect it and explore whether the plan still serves the client.
Blanket rules like "limit eating out" or "cook at home more" can edge into nutrition advice. If those ideas come from the client, coach them. If they come from you, they're a meal plan in disguise.
Where coaching stops
Coaches don't diagnose or treat eating disorders. Frequent loss-of-control eating, purging, fasting or exercising to make up for eating, or rules that cause real distress call for a referral to a mental health professional or the client's physician. Specific food or nutrition guidance, especially for a medical condition, belongs with a registered dietitian or physician.

The Weight-Inclusive Coaching for Clients Who Want Weight Loss package is in development, including how to help clients build flexible plans around food cues without turning them into diet rules.
