Man’s Week-Long Protein Bar Diet Leads To Surprising Body Reactions

Colin Murray thought a week of protein bars sounded like an easy win, clean eating, simple routine, and zero effort. Then the bars started taking over his body in ways he did not expect.

By day two, he was already panicking because he hadn’t had a proper bowel movement, and his stomach felt like it was fighting him. The bloating didn’t just show up, it changed how he looked, turning his once-defined six-pack into something softer and more swollen.

What makes it worse is that even when he tried to “fix it” by sneaking in fruit like blueberries and apples, the relief did not last, and the fatigue kept creeping in.

"I Ate Only Protein Bars For A Week! "

On day two, Murray finally admitted he hadn’t pooped in three days, and the protein bar challenge instantly stopped feeling like a flex.

As the days progressed, Murray faced increasing health issues. By day two, he was alarmed that he had not yet had a proper bowel movement.

His body seemed to struggle with the lack of fiber and other essential nutrients found in regular meals. He openly shared his concerns, noting that he hadn't "pooped in three days," which understandably caused him anxiety. The lack of regular digestion showed that his body wasn’t getting what it needed from the protein bars alone.

“I ate a lot of protein bars, but nothing has come out yet, so that's a little bit alarming. I haven't pooped in three days. That is a long time, and to be honest, it is kind of starting to freak me out a little bit,” he admitted.

The severity of his digestive problems forced him to briefly break his strict diet, adding some fresh fruit like blueberries and apples to help things "move downstairs." While this offered temporary relief, it didn’t resolve all the issues he faced during the week-long challenge.

Nutritional Insights

Colin Murray was challenged to eat nothing but protein bars for a week.

On day four, Murray returned to his protein-bar-only diet and continued to experience discomfort. He felt tired and weak throughout the day, and his bloating persisted.

One of the most concerning observations was the visible change in his physical appearance. Murray, who typically sported a defined six-pack due to his workout routine, noticed that his abdominal definition had diminished. The bloating from the bars made his body look and feel different, indicating that something wasn’t right.

After he added blueberries and apples to get things moving downstairs, he went back to bars on day four, and the bloating came right back.

This is the kind of boundary fight like the neighbor who refused to split a dog walker with their neighbor.

Once Murray noticed his six-pack definition fading while he felt tired and weak, the whole “protein-only” plan started looking less like dieting and more like a body takeover.

In addition to the physical changes, Murray also experienced more general fatigue. By day five, he felt both exhausted and restless.

His workouts were not as productive, as his body lacked the energy needed to perform at its usual level. This decline in his physical performance was a significant red flag that the diet was taking a toll on his body.

As the week ended, Murray's attitude toward protein bars shifted drastically. Once a fan of their convenience, he now saw them in a different light.

He expressed guilt over how frequently he had consumed protein bars in the past, realizing that processed foods, even those marketed as healthy, can negatively affect the body when consumed in excess.

“I feel like I've been poisoning myself for the past five years because I've eaten these a lot—especially this week. Processed food [like protein bars] really just kills your energy, is kind of what I'm noticing... when you eat processed food, it really messes you up.This past week, I haven't gotten sleep; I haven't been able to do anything... They should be an every-now-and-again snack,” concluded this YouTuber.

Murray noticed his workouts were getting more challenging, and he was dealing with a constant feeling of bloating.

By day five, the exhaustion and restlessness hit during workouts, so his routine fell apart right when the week was supposed to be over.

Murray’s experiment showed the importance of a balanced and varied diet. While protein bars are a quick and easy way to get protein, they can’t provide your body with everything it needs.

His bloating, tiredness, and other health issues proved that protein isn’t enough to keep your body functioning well. You also need carbohydrates, fats, fiber, vitamins, and minerals to stay healthy.

This experiment reminds us that convenience shouldn’t come before good nutrition. While protein bars can be handy when you’re in a hurry, they are no replacement for a proper meal.

The results of the week-long protein bar diet experiment highlight the critical importance of nutritional diversity.

Now Murray is left wondering if the bars were doing more harm than he ever agreed to.
