I’m a young professional who’s no stranger to grabbing a quick taco or a candy bar when work gets crazy. Burnout makes you lean hard into convenience, right? But I started wondering what ultra-processed food was really doing to me. So, I decided to eat nothing but fast food, packaged snacks, and frozen dinners for a week. Holy cow, what a ride! 😅 Here’s how it flipped my energy, mood, wallet, and mental clarity upside down, and why I’m all about healthy eating now.
Why I Lived on Junk for a Week
Let’s be real: ultra-processed food is everywhere—cheap, fast, and oh-so-tempting when you’re buried in emails and feeling fried. I wanted to know what would happen if I made it my entire diet for seven days. Would I be fine, or would my body throw a fit? Spoiler: it threw a fit. Here’s what went down and how it changed my take on healthy eating.

My Energy Was Nonexistent
Three days in, eating nothing but burgers and soda, I was a total zombie. By lunchtime, I’d crash so hard I could barely follow a meeting. I remember my coworker Alex giving me a side-eye when I zoned out, like, “Dude, you okay?” My brain was foggy, no mental clarity in sight, thanks to all that sugar and junk. I’ve since switched to easy stuff like oatmeal or fruit in the morning. Whipping up a smoothie—check our breakfast hacks—takes me five minutes and keeps me going strong.
I Got Super Cranky
By day four, I was a grump. A slow Wi-Fi connection or a loud neighbor had me ready to lose it. I even got snappy with my friend Sarah over a dumb text, and she was like, “Chill, what’s your deal?” 😬 All that ultra-processed food, loaded with weird additives, was messing with my mood. Now, I keep nuts or a little dark chocolate in my bag, tossed into a lunchbox (like these from our kitchen faves). It’s made me way more even-keeled, even on hectic days.
My Wallet Was Crying
Eating takeout and snacks all week was a money pit. I was dropping $10 on fast food lunches and $3 on candy bars just to stay awake. When I checked my bank account, I’d burned through $80 extra—yikes! I thought, “This is not it.” Now, I’m hooked on meal-prepping simple meals like rice and veggies. Some cheap storage containers (see our meal-prep ideas) save me time, and I’m banking $15 a week for stuff like concert tickets.
My Body Felt Like Trash
By day six, I was so bloated and sluggish, my skin looked like it gave up. My partner laughed and said I looked “like a soggy fry,” and yeah, he was spot-on. 😆 All that ultra-processed food was dragging me down. I’ve gone back to basics—salads, chicken, and lots of water, with a trusty water bottle (like these in our eco picks). A couple days of real food, and I felt light, clear-headed, and ready to roll.
A Better Way to Feed Myself
This junk food week was a reality check. Ultra-processed food might be a quick fix, but it trashes your energy, mood, and cash. As a young professional dodging burnout, I’ve learned healthy eating doesn’t need to be fancy. I grab an apple instead of chips, cook a big pot of lentils on Sundays, and chug water all day for mental clarity. I still sneak a burger sometimes, but these tweaks make me feel alive, not like I’m running on empty. Work’s easier, and I’m not scavenging for snacks.
Try One Healthy Swap
My diet impact experiment showed me food is everything—how you think, feel, and spend. Young professionals, I know burnout makes healthy eating feel like a chore, but start small. Swap one processed snack for something fresh this week. You’ll feel sharper, happier, and maybe even richer.
