Question
I am a 48-year-old middle school teacher (162 cm, 79 kg, waist 88 cm).
Over the last two years my weight has crept up. A coworker kept pushing me to buy an expensive $80 herbal 'skinny detox tea' cleanse that promises to flush 10 pounds in a week. My gut tells me it's a scam or harsh laxative.
Tonight I am making dinner for my family: baked salmon filets, roasted red potatoes with olive oil, and steamed broccoli.
Can you:
- Give me the sourced WHO/NHS adult screening markers for my height, weight, and waist without shame?
- Tell me how to configure tonight's salmon and potato meal using the visual plate method instead of calorie counting?
- Give me one evening movement step to build momentum instead of falling for detox teas?
Answer
1. Adult screening markers (population-level, not a verdict)
For 162 cm / 79 kg, your BMI is 30.1 — the WHO/NHS adult obesity population marker (BMI ≥ 30). NHS adds: when BMI is under 35, waist less than half your height is the separate "tummy-fat" check. Your waist 88 cm ÷ height 162 cm = 0.54, which is at or above the half-height line. Muscle, age, sex, and ethnicity all change how a screening number reads — these are markers, not a diagnosis.

2. Tonight's plate (visual, not a calorie budget)
You already cook the right dinner — keep it, shift the shares.
| Share | Already on tonight's menu | Note |
|---|---|---|
| ½ plate | Steamed broccoli (add a green side if you want) | The largest share |
| ¼ plate | oasted red potatoes | The starch |
| ¼ plate | Baked salmon filet | The protein |
| Drink | Water on the table | Skip the sugary bottle |
A drizzle of olive oil on the potatoes is fine; that's not what moves the marker — the vegetable share is.

3. One evening movement step
After dinner, one walk out the door — about 20 minutes, brisk enough that you can talk but not sing. That is the AHA adult heart-health pattern (150+ minutes a week) shown in one session. If 20 is too much tonight, walk 10 and add a few minutes each evening. The walk is for head and sleep, not to "undo" the salmon.

4. The coworker's $80 "skinny detox tea" — your gut is right
The FDA runs a public running list of weight loss products — teas, "detox" blends, "slimming" capsules — that lab-tested positive for hidden drug ingredients (undeclared stimulants, laxatives, sometimes prescription drugs). Their own page says, word for word: *"Many products that claim to help with weight loss — such as diet pills; fat-burning pills; and weight loss supplements, pills and teas — are likely to be contaminated with dangerous hidden ingredients."* The list is updated monthly and includes products sitting in the exact "skinny detox" lane the coworker is selling. Skip the $80. If she pushes back, the FDA Tainted Weight Loss Product list is the page to point her at.

What I can't do this turn: give you a daily calorie number, a target weight, or a "kg per week" rate — those would be guessing for you. The pattern above (plate + one evening walk, sustained over months, not days) is the trajectory that actually changes those screening numbers.
