As those who follow my journal are aware, several weeks ago I was in a position where I was unable to eat my normal food and had to make do with typical cafeteria fare. I experienced some unpleasant side effects from this in the form of large amounts of water retention even though I did my best to eat only protein and fat and consume no obvious carbs.
Two weeks ago my wife and I attended a summer family gathering and I decide to throw caution to the wind, eat all the forbidden foods, and see what would happen. The results are rather instructive and should be given consideration before a person decides to commit to a zero carb lifestyle.
The framework of the experiment was that I ate my normal meal during the day and then consumed a large amount of carbs in the evening between about 6pm and 9pm. The next day I returned to my normal meat only fare. Here’s what happened.
At 4pm I ate 1.5 lbs of raw meat and fat after which we headed off to attend the family gathering.
Between 6pm and 9pm I ate the following:
6oz of 7Up,
½ dozen cheese and cracker appetizers
3 pieces of thin crust pepperoni pizza
2 large chocolate chip cookies
1 small scoop vanilla ice cream
1 large slice of watermelon
½ cantaloupe
I found that the more I ate the more I wanted to eat of these foods. My intention was to eat one piece of pizza, (after all I had already eaten a full portion of my normal food and really wasn’t all that hungry), but found myself going back for seconds and thirds. Chocolate Chip Cookies are my favorite and I justified 2 as it was “only this one time and I deserve it”. Probably my favorite thing in the world is ice cream and I would have loved more but they ran out. Large plates of sliced melons were available all night long and I found myself picking up a piece every time I walked by them even though by this time I was pretty well stuffed – I still wanted more. We finally left about 9pm and my binge was forced to an end.
By 10pm I noticed that I was very thirsty and just couldn’t get enough to drink. I checked BG and it had risen in to the low 200s. It might have gone higher but I didn’t start measuring until I got home.
I went to bed about 11pm and woke up twice during the night from thirst and each time consumed 16 oz of water. BG started to fall but this process was very slow. It took almost 24 hours to get back down below 100. My thirst continued for about 36 hours and during that time my weight increased by about 12 lbs, and my ankles, feet, and hands swelled up with edema. I was very uncomfortable to say the least.
Even though I returned to my normal diet the next day, my thirst continued for about a day and half and I continued to gain weight during that period. I’d say that I hit the peak at about 48 hours before things started to reverse.
On the 3rd day I started feeling better but I was really puffed up with fluid retention. When I stood for long periods (working in my shop) fluid would pool in my lower legs, feet and ankles making them stiff and painful due to stretching of the skin. I’d go to bed and throughout the night the fluid would redistribute more evenly throughout my body and I would wake up with my hands noticeably stiff and swollen, but legs and ankles less so.
After the 4th day I began to see a slow drop in weight and this continued at the rate of about one pound per day over the next week and a half until now I’m almost back to normal.
Of course I really have no idea of what is actually happening but here are the conclusions I’ve drawn from this experience:
My guess is that, after 3 years of zero carb, my body is no longer conditioned to handle large carb loads efficiently. Insulin production is probably low and when BG was suddenly and unexpectedly driven very high, my body called for large amounts of water in an attempt to dilute BG to bring it down to safe levels.
I have had small amounts of carbs in the past, but in very small amounts, a single bite of something just to taste it as an example. This might have amounted to 5g of carbs and this caused no detectable problem, but clearly large infusions of carbs are now a problem for me.
My previous experience with the cafeteria food suggests that since I experienced the same symptoms as with this current experiment, there must have been a significant amount of hidden carbs in what I was eating. Maybe sugar in the sausage, lactose in the cheese, and eggs may have more available carbs than expected. Also it took much longer for the edema to develop, though it was just as severe, so it seems that lower levels of carb intake over an extended period of time will exceed the body’s capacity to handle ever rising BG levels once the body has shut down those systems through adaptation to a zero carb diet.
It took several months for my body to adapt to zero carbs and during that time I was rather uncomfortable. I think that if I were to decide to return to a high carb diet, I would face a similar period of adaptation back to where my body handled carbs efficiently again. I think this is an important consideration for anyone contemplating adopting a zero carb lifestyle. You should not make this decision lightly.
Don't take this to assume that I'm now sorry for being zero carb - nothing could be further from the truth. My health has improved dramatically, and I have a much better quality of life. I can do things today that I couldn't do as recently as 5 years ago, and at an age when most are taking more and more medications while at the same time having to reduce their activity levels, I'm off all meds but one, have reduced my single remaining medicaton to 1/4 the original amount, and increased my activity levels almost to what I was doing in my mid 30's. The trade-off of now being forced to restrict my carb intake or suffer the rather unpleasant consequences is well worth it for me.
