The Wedding Deadline: 14 kg in Eight Weeks
A 30-year-old woman, 165 cm and 82 kg (BMI 30.1), books a consult. She wants to be 68 kg on her wedding day, eight weeks away - about 1.75 kg per week. She has done two crash diets; each produced 8–10 kg in three months and full regain within a year. She works 50 hours a week, strength trains once weekly, and drinks four coffees daily. Her dress is already ordered in a size that fits at 75 kg. She says, 'I just need you to give me a meal plan and keep me accountable. I can do strict - it's the after that's the problem.' She also mentions that her mother has type 2 diabetes and that she is scared of 'ending up like that.'
1. Evaluate whether her goal is realistic. Show the arithmetic and describe how you would present it.

Run the numbers out loud. 14 kg in 8 weeks is 1.75 kg/week, or about 2.1% of body weight per week. Evidence-based fat loss runs 0.5–1% per week - for her, 0.4–0.8 kg/week, which is 3–6.5 kg over eight weeks.
A 1.75 kg/week rate requires roughly a 1,900 kcal/day deficit. With a BMR near 1,540 kcal, that means eating below BMR for two months, which is associated with lean mass loss, gallstones, micronutrient gaps, poor training quality, and - according to her own history - a predictable binge-restrict rebound. So the goal is not a willpower problem; it is arithmetically outside what her body will tolerate comfortably.
Reframe: a realistic wedding target of 4–6 kg, putting her near 76–78 kg and close to the dress fitting at 75 kg, with 68–72 kg as a 12-month goal. Present the numbers as information rather than judgment, then ask which matters more - the number on the day or not repeating the regain. The aim is for her to state the trade-off herself rather than hear it as a restriction imposed on her.
2. Build a plan with calorie targets, macronutrients, and SMART goals.

Energy: BMR via Mifflin–St Jeor is about 1,540 kcal; TDEE at light activity is roughly 2,150. Prescribe 1,650–1,700 kcal for a 450–500 kcal deficit. Protein 1.6 g/kg, about 130 g; fat at least 50 g; fiber 25–30 g; carbohydrates filling the remainder and placed around training.
Training: strength work two to three times per week and 8,000 steps daily. Compensate for the 50-hour week with two batch-cook sessions, a standing protein breakfast, a planned afternoon snack, and coffee capped at two cups, always with food.
SMART goals must be behavioral, not outcome-based: 'By Friday of each week I will have completed two strength sessions and three planned dinners, logged,' not 'lose 2 kg.' Weigh daily and use a seven-day average to avoid reacting to noise.
Retention plan from day one: name her two highest-risk situations (dress fittings, wedding-week stress), script a response for each, and set a maintenance calorie range to begin immediately after the wedding rather than drifting. Screen the diabetes concern by referring for A1c and waist measurement rather than reassuring her.
3. She asks you to 'just keep me accountable.' How do you handle that request and the regain history?

What she is describing is external control, and her history shows external control is exactly what collapses afterward. Shift the structure to self-monitoring: she logs intake and weights, and you review weekly and problem-solve together. That keeps your involvement high without making you the mechanism her adherence depends on.
Use motivational interviewing. Ask what happened after each of the two prior diets, what she wants to be different at the wedding and at 40, and what she is afraid of. Reflect the ambivalence rather than arguing with the 14 kg target - arguing produces compliance in the session and abandonment afterward.
Build the 'after' into the plan now: a maintenance calorie range, a weigh-in band (for example, act if the seven-day average rises more than 2 kg over two weeks), and a return-to-logging rule. Also screen for disordered eating patterns before prescribing any strictness.
If she insists on the 14 kg, document the conversation, decline to promise it, and offer the closest evidence-based version: 4–6 kg by the wedding plus a structured maintenance phase.
