Surviving grad school on Oreos and multivitamins

Fall break is here, so it is time to catch up on the daily activities we have been neglecting because of school; such as putting away that massive floordrobe that has accumulated, or cooking a well-balanced and nutritious meal rather than survive off of the sad smashed Oreos at the bottom of your backpack. As I reflect on how sad my diet has been over the last 53 days of the semester so far, I wonder to myself: could you actually survive on Oreos if you also take a multivitamin?

 Homeostasis involves complex mechanisms in order to maintain weight, energy production and expenditure and maintain cellular function (Galgani et al, 2008). Cellular function needed to sustain life depends on metabolism homeostasis, which is the balance of both catabolic and anabolic rate of macromolecules and other nutrients. In other words, the intermolecular coordination of chemical signaling and organ systems is used to store and burn fuel to keep you running smoothly (Galgani et al, 2008). 

In our thought experiment, someone who has an increased amount of energy stores (i.e. overweight), could sustain themselves for a longer period of time on a diet of Oreos and vitamin supplements. An extreme case was with a man named Angus Barbieri, who was morbidly obese, survived with no food for a total of 382 days. Barbieri weighed in at a total of 456 pounds when he first participated in a fast that was supervised by medical professionals, but as weeks turned to months, Barbieri decided to keep going until he reached his goal weight of 180 pounds. Doctors monitored his health and noted that he was hypoglycemic which confirmed he wasn’t eating. Barbieri was occasionally given multivitamins, sodium and potassium supplements throughout the duration of his fast (Loria, 2017). Barbieri and other patients who have undergone prolonged periods of fasting were morbidly obese, indicating that fasting is a potential treatment in the field of bariatrics. As the number of obesity cases rises in the United States, more people are likely to turn to fasting trends (Hruby, 2015). 

The average student could survive only eating Oreos and multivitamins, however it’s a terrible idea, considering that three Oreos have 14g of sugar and only 1g of protein, not to mention the saturated fat content! Depending on the amount of stored energy the student has, they could potentially lose weight on an all Oreo diet, but don’t confuse this for a healthy diet. This logic also extends to juice cleanses, “detox” diets, and other fad diets. They are unhealthy even if they do result in weight loss since they lack critical nutrients that a body needs to maintain homeostasis. A combination of diet, exercise, (and an occasional Oreo) is the best way to maintain proper metabolic function and energy balance.

  1. Hello Angelina! I too have found myself reaching for the easy, immediately available foods like frozen pizza or boxed Mac n cheese over the past few months of our program! I think it is important that you noted while a feat such as only surviving on minimal nutrients and supplements in possible, it is not the best option. I would like to tie this in with what we learned in our TBL #1 about LTP. A study in 1983 found that mice that were exposed to malnutrition had a more difficult time developing potentiation, and evidence of long term potentiation was seen to decrease within 24 hours after stimulation (Jordan & Clark 1983). This is just more evidence that maintaining a healthy diet and lifestyle will not only give us the nutrients to maintain homeostasis, but also prepare us to take on the academic challenges of this program!

  2. Hi Angie! I was excited to read your post because I was recently wondering about the benefits of taking vitamins supplements versus getting vitamins straight from your diet. After keeping track of my calorie and calcium intake for physiology class, I realized that I was not reaching the recommended amount of calcium from my diet alone. This got me wondering if I could and should simply take vitamins everyday to fix this deficiency. Are getting the required vitamins and minerals from a pill the same as getting them naturally from your diet? Vitamin supplements seemed like a quick and easy fix, but I wasn't sure if they had the same benefits. Your post along with an article from Harvard Health Publishing helped me to understand the importance of getting nutrients from food first, and then using supplements to plug any gaps. This is because nutrients are more potent when they come from food (Harvard Health Publishing 2015). Thanks for your post!

  3. Hi Angie! I can also agree that my diet has been a bit questionable since starting this program - convenience has definitely outweighed nutrition more than I'd like to admit! The story of Angus Barbieri and his incredible amount of weight loss is fascinating; I can't even begin to imagine living off of nothing but Oreos for over year. This made me wonder if he was actually getting the proper amount of vitamins despite taking vitamin supplements since some of the essential vitamins like A, D, E, and K are all fat-soluble. I'd be curious to know if the Oreos alone were sufficient in helping him to absorb nutrients, or if perhaps adipose tissue holds a greater reserve of these vitamins to be used over time. One study found greater total body vitamin D stores in obese patients as compared to normal weight patients (Carrelli et al. 2017), but it would be interesting to see how these stores could be utilized, if at all, during an intense period of weight loss.

  4. How many Oreos do you need to eat per day to get enough Calories anyway? I looked up the nutrition information and it says that one serving is three cookies with 160 Calories in each serving. That means for Calories alone we need 12.5 servings or 37.5 cookies to get 2000 Calories each day. That’s just over one of those large three row containers of Oreos if that’s the only food you’re eating. That also means that you’d be getting 125% of your daily saturated fat and sugar (not as bad as I expected), 112.5% of your daily carbohydrates, and 1687.5% of your daily sodium (yikes!). WIth no dietary fiber, potassium, or any vitamins to speak of, you’re obviously right that it wouldn’t do the trick, though you’d still get 100% of your daily iron requirements (but probably only if you’re male).
    This actually made me think of the person who went blind and started going deaf because he only ate a few things (Pringles, fries, and stuff like that) and just plain didn’t get the nutritional building blocks to perform normal bodily functions anymore.
