Night-Shift Nurse Wants 9 kg in 8 Weeks
Your client is a 34-year-old emergency department nurse who works three 12-hour night shifts per week and has two children under 10. Her BMI is 33.4, waist 101 cm, and she wants to lose 9 kg in 8 weeks for her sister's wedding. She has tried keto and 16:8 fasting, lost 4 kg each time, and regained it. She eats her largest meal at 1 a.m. after her shift, often fast food, and reports 'all-or-nothing' thinking: 'If I mess up one meal, the day is ruined.' She says, 'Just tell me exactly what to eat and I'll do it,' but she has missed two of the last five sessions because she was too tired. Her perceived stress score is high, and she sleeps about 5 hours on workdays. She has no diagnosed eating disorder but feels ashamed after overeating. She wants a meal plan today.
1. How would you respond to the 9-kg-in-8-weeks goal and her request for a prescriptive meal plan? Show your reasoning.

Nine kilograms in 8 weeks is about 1.1 kg/week, or roughly 1% of body weight per week for her. That is at the aggressive end and may be unsustainable given her shift work, sleep debt, and history of regain. Rather than simply saying no, I would explain the trade-off: a slower rate (about 0.5–1 kg/week) is more compatible with preserving lean mass and building habits.
I would ask what the wedding means to her and what she wants to feel like, then negotiate a process goal: for example, 'eat a protein-containing meal before each night shift and pack two snacks' rather than 'follow this exact plan.' Her request for a prescriptive plan is understandable, but it has failed before because it removes autonomy. I would offer structure (a flexible template with 2–3 options per meal) and ask her to choose the first change. I would also set a review date and clarify that I am not promising a specific weight.
2. Select two behavioral strategies that fit her night-shift schedule and all-or-nothing thinking, and explain why each fits.

If-then plan for the 1 a.m. meal: 'If I finish my shift and I am too tired to cook, then I will eat the pre-packed protein and rice in the fridge before driving home.' This works because it targets the exact high-risk cue (post-shift fatigue) and reduces in-the-moment decision fatigue.
Self-monitoring with a next-meal rule: she records meals briefly and, after an overeat, writes one next action instead of labeling the day ruined. This directly counters all-or-nothing thinking by making the next choice, not the whole day, the unit of change.
I would also schedule sessions on her days off and keep them short. I would not use a strict 16:8 window unless she chooses it, because her night shifts already disrupt eating timing and the previous plan led to rebound. Success would be measured by planned meals and sessions attended, not only weight.
3. She misses two sessions and gains 1.5 kg. What is your coaching response?

I would start without shame or a lecture: 'Two missed sessions and a 1.5 kg change-what got in the way?' I would listen for barriers such as sleep, childcare, or a work stretch, and normalize that weight fluctuates with sodium, carbohydrates, and the menstrual cycle.
Then I would review the plan: was it too ambitious? Which one behavior is still doable? I would shrink the next step, for example one pre-shift meal prep and one 10-minute walk, and rebook a short check-in. I would ask about binge episodes, purging, or persistent low mood; if present, I would refer to an eating disorder or mental health professional. I would not add a stricter diet as a response to a missed session, because that reinforces the all-or-nothing cycle. The goal is to re-establish contact and confidence, not to punish.
