Question
I am a 34-year-old male, 178 cm tall, weighing 94 kg, with a waist circumference of 92 cm. I sit at a desk all day.
I've been feeling sluggish and want to lose weight fast. A friend suggested I do a strict 1,200 kcal/day crash diet for the next 7 days and skip meals.
Can you calculate my BMI and waist marker, tell me if doing a 1,200 calorie crash diet is safe, and give me a realistic dinner plate shift and movement step for tonight instead of starving?
Answer
Your numbers
- BMI 29.7 — WHO adult overweight population marker (obesity cut-off is 30). It's a screening number, not a diagnosis; muscle and waist change the read.
- Waist-to-height 0.52 — at or above half your height, which is the NHS tummy-fat concern for adults with BMI under 35.

On the 1,200 kcal × 7 days crash + skipping meals
I'm not going to coach that plan. A 7-day very-low-calorie crash with skipped meals for a 94 kg male typically causes muscle loss, rebound over-eating, worse sluggishness, and — with a desk job and no medical supervision — a real risk of fainting or blood-sugar swings. It also doesn't produce a result you can keep. The work that *does* keep weight off is small, repeated, not heroic.
So: no kcal target, no "lose X kg in 7 days." If you want a hard medical plan (very-low-calorie diet, prescription, or surgery), that's a conversation with your clinician — it needs monitoring.
Tonight instead
Plate (works on whatever you already cook — rice, noodles, stew, stir-fry, sandwich plate):
| Half | Quarter | Quarter | Glass |
|---|---|---|---|
| Vegetables or salad (the biggest share) | Protein — beans, fish, chicken, egg, tofu | Starch — rice, pasta, bread, potato | Water |
If you're cooking a stew or stir-fry, just push the vegetable portion up and the starch down. Don't rebuild the meal — change the proportions in the pot you already make.
Move: a 20-minute walk after dinner. Brisk enough that you can't sing easily but can talk. That's the whole job tonight — shoes, water, daylight or streetlight, traffic on the right side.
One honest limit
"Sluggish all day at a desk" can be more than deconditioning — thyroid, sleep, blood sugar, anemia are common drivers and a clinician can check. If the walk + plate +7–8 h sleep doesn't shift how you feel in 2–4 weeks, please book a visit rather than doubling down on restriction.
