Twenty-Five Pounds by the Wedding
Danielle, 34, is 168 cm and 84 kg (BMI 29.8). She marries in 10 weeks and wants to lose 11 kg (25 lb) by then, which she describes as 'about 2.5 pounds a week.' She drinks two regular sodas daily, skips breakfast, eats restaurant meals five nights a week, and sleeps 5-6 hours. She lost 6 kg on keto two years ago and regained 8 kg. She asks about a 'detox and fat-burner' stack she saw online and whether you will write her a meal plan. She says she 'hates' tracking food. She reports no diagnosed eating disorder and no other medical conditions.
1. Evaluate her goal quantitatively. What deficit does it require, and what target would you propose instead?

Do the arithmetic before responding. 25 lb in 10 weeks is 2.5 lb/wk. At roughly 3,500 kcal per pound of fat, that is about 8,750 kcal/wk, or a 1,250 kcal/day deficit.
Check it against her energy needs. Using Mifflin-St Jeor for a 34-year-old woman, 84 kg, 168 cm: BMR is approximately 1,560 kcal/day. With a light-activity factor of about 1.3, maintenance is roughly 2,000 kcal/day. A 1,250 kcal deficit would leave her near 780 kcal/day - below her BMR, below usual minimum intake guidance for women, and very unlikely to preserve lean mass or be sustained for 10 weeks, let alone afterward.
Reframe. A rate of 0.5-1 lb/wk implies a 250-500 kcal/day deficit and a realistic 10-week loss of roughly 5-10 lb (2-4.5 kg). Say plainly that this is not a judgment about her willpower - it is what the math supports. Ask what she wants the wedding to feel like and negotiate two additional non-scale outcomes (energy, sleep, strength, how her dress fits) so the whole plan is not hostage to a number on the scale. Her history of loss and regain argues for a slower rate, not a faster one.
2. Name two behavior-change strategies that fit her stated constraints, and justify them with a theoretical basis.

She has told you what she will not do (track food), so build around it.
1. Stimulus control and environmental restructuring for the sodas. Two regular sodas is roughly 250-300 kcal/day of liquid energy with no satiety. Remove them from the house, keep chilled sparkling water or a filled bottle in the same refrigerator spot where the cans lived, and stop buying them in multipacks. This is a direct application of stimulus control from social cognitive theory: change the cues rather than relying on in-the-moment willpower, which is exactly where her past attempts failed.
2. Implementation intentions (if-then plans) for the five restaurant meals. Before each week, she writes: 'If I am at a restaurant on a weeknight, then I order a non-fried protein and a vegetable first and box half the entree.' This is an if-then plan that pre-decides the behavior in the environment where it will occur, and it satisfies her refusal to log food.
Also address sleep. Five to six hours is associated with higher energy intake and weight regain. Set a consistent bedtime as a target in its own right. Use motivational interviewing - she is in preparation/action, and her past regain should be discussed without confrontation.
3. How do you respond to the supplement and meal-plan requests while staying inside your scope?

Supplements. 'Detox' products and thermogenic 'fat burners' have no credible evidence of meaningful fat loss, are loosely regulated, and carry real risk (stimulants, blood pressure effects, hepatotoxicity, interaction with medications). You can describe that evidence gap and the safety concerns, tell her not to start a stack before her wedding without discussing it with her physician or pharmacist, and note that a stimulant-containing product plus a 10-week crash diet is a bad combination. What you must not do is recommend a product or dose.
Meal plan. Detailed nutrition prescription is the registered dietitian's scope, not the EP-C's. You can provide general education consistent with national dietary guidelines - reduce sugar-sweetened beverages, include protein at breakfast, build meals around vegetables - and refer her to an RD for an individualized plan. Say this clearly rather than improvising a plan.
Safety flag. A 2.5 lb/wk target plus 'hates tracking' plus a hard deadline warrants screening for restrictive or compensatory behavior. If she describes skipping meals to 'bank' calories, purging, or weighing herself many times daily, pause the weight goal and refer to a clinician. Also confirm her BMI and lack of comorbidities in her file before setting any calorie target.
