Joey Thurman enjoys a scroll-stopping well being and health problem. After we linked and he shared that he was about to do a 24-hour Dunkin’ Donuts problem whereas sporting a steady glucose monitor, I stated, “I need in.” Thurman, a Chicago-based health knowledgeable, who’s labored with a variety of clientele from WWE wrestlers to hedge fund executives, is understood for placing his physique by self-experiments to higher perceive what his shoppers may undergo.
“I’m a human guinea pig myself,” he advised me. “I like actually seeing what occurs to my physique and the way I really feel.”
This time, he got down to eat nothing however Dunkin’ Donuts a la carte for a complete day whereas monitoring his blood sugar response. Suppose sandwiches, wraps, donuts, bacon snacks, and low. I jumped in to deliver a feminine perspective to the metabolic insanity. Outfitted with steady glucose screens (CGM) and a meals log app, we needed to see if resistance coaching, walks, and apple cider vinegar may blunt the harm, or whether or not the glucose curler coaster would run the present.
What the Numbers Confirmed
I aimed for roughly 2,000 energy and 100 grams of protein. Nonetheless, it proved to be a problem at a sequence the place donuts and croissants rule the menu. My precise log got here in at slightly below 2,400 energy: about 94 grams of protein, 202 grams of carbs, and 129 grams of fats. Joey went greater in each sense, consuming 4,500 energy with a a lot increased protein goal. He carries far more muscle mass than I do, so his goal made good sense.

My blood sugar began steady sitting at my 85 mg/dL baseline, however it shortly became a Six Flags curler coaster experience that by no means appeared to finish. By the point of the problem I had been sporting the CGM for 10 days, so I knew my regular patterns nicely. Most meals would spike me to 95-98, hardly cracking 100 except dessert was concerned. But each single Dunkin’ meal launched me into the triple digits.
Thurman’s ranges had been barely totally different however equally revealing. His glucose was within the triple digits a lot of the day and even hit 160 mg/dL at one level.
The spikes had been only one factor, it was the relentless frequency. To hit our protein aim, Joey and I needed to eat 5 instances all through the day, roughly each three hours. This created a metabolic nightmare the place we’d set off one other insulin response earlier than our glucose may even return to baseline from the earlier meal. Our pancreases had been working time beyond regulation, pumping out insulin to cope with waves of refined carbs, by no means getting a break to let our blood sugar really stabilize. You should definitely take a look at his video as he logged the complete day! He even added a management day a day previous to see how Dunkin Donuts would impression his blood sugar with none exercise concerned.
Why Bioindividuality Issues
The variations between us had been attention-grabbing and certain rooted in bioindividuality. My blood sugar by no means soared into excessive highs, however it lingered longer after meals. Thurman defined that could be as a result of excessive fats content material. “These are increased fats meals, which slows gastric emptying,” he famous once I described my sluggish glucose clearance.
However essentially the most fascinating distinction confirmed up in a single day. My knowledge settled into the 80s mg/dL and stayed regular. Joey’s, however, had a pointy drop to 73mg/dL at 3:15 a.m., which was rather a lot decrease than at any level all through the day for him, adopted by a rebound spike to 140 mg/dl. All that possible a liver glucose dump that coincided precisely with him waking up.
“I dropped all the way down to 73 [mg/dL] at 3:15 AM, after which at 3:45, it jumped as much as 140 [mg/dL],” Joey stated, checking his sleep knowledge. “I used to be awake at 3:48. The very same time. That’s instantly coinciding.” For athletes and lifters who typically wrestle with sleep high quality, that type of glucose swing is a reminder of how meals decisions and meal timing may ripple into restoration.
Energy vs Starvation
What struck us each was starvation. Regardless of consuming 4,500 energy, Thurman was ravenous. “The starvation was actually attention-grabbing,” he mirrored. “I felt extra full than another day having half the energy.”
I felt the identical approach, and we had been each “hangry” all day.
The wrongdoer, he defined, was possible the shortage of fiber on the Dunkin’ menu. On the Dunkin’ day, Joey consumed simply 11 grams of fiber, whereas his common is at the very least six instances that quantity. Whereas fats slows gastric emptying, it doesn’t set off the identical satiety indicators as fiber-rich meals. We had been consuming continuously however by no means feeling really happy.
How Motion Impacted Blood Sugar
From a coaching perspective, the outcomes had been blended. Thurman loved the pump that comes with carb-loading. He stored his exercise easy and accessible. He did three working units every of again squats, bench press, and cable rows, totaling about 12-15 compound motion units. “My exercise was nice. I imply, I’m at all times vascular, however I used to be all pumped up, able to go,” he stated.
My expertise was totally different. I tackled a lower-body HIIT circuit. I may nonetheless raise, however my legs felt heavy, and the vitality swings made it exhausting to remain targeted. By dinner, the bacon-and-donut combos produced what felt like a pharmaceutical yo-yo of vitality and mind fog.
Thurman’s post-meal exercises and walks made a dramatic distinction, he recalled. Along with resistance coaching, he additionally tracked over 14,000 steps that day. “It stayed just about steady the complete time from that stroll a couple of hours beforehand,” he shared. “Motion is the most important distinction maker, and a brisk stroll is the quickest, best and handiest hack.”
I additionally give credit score to his skeletal muscle performing like a glucose sponge, pulling sugar out of his bloodstream by insulin-independent pathways.
The Sensible Takeaways
So what must you take from this metabolic rollercoaster experience?
Stroll it off, actually. A stroll after meals is an easy however highly effective instrument. As Thurman put it: “5 to 10 minutes after a meal. Do it thrice a day. That’s half-hour of motion with out ‘figuring out.’ Sesame Road math,” he defined with a smile.
Protein helps, however it’s not a defend when paired with excessive fats and sugar. We each hit our protein targets however nonetheless felt undernourished and glucose spikes had been nonetheless frequent.
Fiber stays the muse for satiety and steady vitality. The considerably decrease ranges of fiber than what we each had been used to left us hungry the complete day.
Timing issues. Consuming too often earlier than glucose from the final meal would clear stored our blood sugar ranges elevated between meals.
The Psychological Sport
The psychological element proved as essential because the physiological. Thurman’s perspective on deliberate indulgence versus guilt-driven restriction was notably insightful: “Should you’re going to have a day the place you go loopy, be ready mentally. You want to know your self and your responses. Should you can’t have a cheat day with out beating your self up the subsequent day, don’t.”
He advocates for reframing “cheat days” as strategic refeeds round high-activity durations. “Construction it round a giant exercise day, like leg day.”
The Backside Line
You’ll be able to’t outlift donuts eternally. Protein and train blunted the glucose spikes, however fats, sugar, and low fiber nonetheless dragged our focus, starvation, and restoration.
The information confirmed what we each felt: train helps rather a lot, however it isn’t a free cross. A easy stroll after meals can work wonders, however it might probably’t fully override the metabolic price of consuming like a toddler at a birthday celebration for a complete day.
Most significantly, this experiment bolstered that sustainable well being is about making knowledgeable decisions and understanding the results. Typically which means strategically deliberate indulgence round exercise. Typically it means strolling away from the donut case totally.
