👔 "Can shedding weight actually help you shine at work? We dug into the numbers."
🧙♂️ Hi there! I’m The Data Whizard, the guy who stirs up emotions and numbers into magical insights.
Have you ever had those mornings where just getting out the door feels like climbing a mountain?
Or those workdays when even your usual tasks seem... heavier than usual?
It might not just be the workload — it might be your body talking.
💡 It turns out, when we take care of our bodies, something bigger happens:
We feel more in control — and that mindset change spills into how we feel at work.
📊 That’s why we looked at a national dataset — the Korea Employment Panel Survey (KEPS) — to explore:
👉 What happens to job satisfaction when people lose weight
👉 How other factors like age and income fit into the picture
👉 And whether self-care can actually be your career superpower
- Dataset: Korea Employment Panel Survey (KEPS)
- Sample: 5,000 working adults across Korea
- Statistical Model: Fixed Effects Panel Regression — basically, we track changes within the same person over time
- Stata Command:
xtreg job_satisfaction weight_loss age income, fe - Main Variables:
😊 Job Satisfaction — How content people are with their jobs
🥗 Weight Loss — Any personal weight changes they’ve had
👶 Age — Because energy levels and outlook shift over time
💸 Income — Because, let’s be honest, money does affect peace of mind 
- 🥗 Weight Loss (β = +1.15, p = 0.002): Each kilogram (2.2 lbs) you lose can boost your job satisfaction score by 1.15 points. It’s not just about looking better — it’s about feeling back in control. That confidence travels with you into every meeting, every pitch, every project.
- 👶 Age (β = -0.05, p = 0.045): As we get older, there’s a very slight dip in job satisfaction. It might reflect burnout, or feeling disconnected from younger peers or company culture.
- 💸 Income (β = +0.021, p = 0.000): More money still helps — a ₩1,000,000 (roughly $750) raise means a 2.1-point increase in satisfaction. But, interestingly, it’s not as powerful as feeling good in your body.
📉 This graph says it loud and clear: Weight loss had the biggest impact on job happiness — even more than age or income.
Why? Because when you care for yourself, your self-worth rises. And that means you show up at work not just as a worker — but as someone who believes they belong at the table.
- 💪 "After losing weight, I didn’t dread Mondays as much."
- 🎯 "Even my commute felt lighter. I walked with purpose again."
- 🧘 "That feeling of control — it bled into how I tackled work, too."
✅ This isn’t just about dieting. It’s about a feedback loop:
Self-care → Confidence → Career satisfaction.
The numbers — and people’s stories — agree.
💼 So if your work life feels foggy or exhausting, maybe your next power move isn’t a new strategy — it’s a walk, a stretch, a salad. Small wins stack up.
It is not the mountain we conquer, but ourselves.
— Sir Edmund Hillary
