While weight management is a simple equation, it still has nuances. On our journey, there were ups and downs (no pun intended) as we measured our weight every day. We started to notice a trend. Every weekend, we would see our weight go up 2-3 lbs. We knew it wasn’t real weight such as new muscle or fat. This post talks about one aspect of what we found which is another reason that we stopped eating out as often.
The Weekend Bump
We travel a lot on weekends. For us, it was normal to eat home-prepared meals all week, and then eat out on the road. That was a simple tradeoff for us. We couldn’t or didn’t want to maintain a specific schedule or may have no way to heat something we made on the road. Let’s face it, road food was also a treat.
We also tracked our weight every week. If you are traveling, scales weren’t always in the picture for weekends. What we noticed would be Friday we would be at weight X. On Monday morning we would be up 2-4 lbs. By Tuesday or Wednesday, we will be back at X. Maddening to see what happens every week. When we decided to start tracking our calories, we started to see an obvious trend.
On the weekends our calorie intake went up. Yay! We found our smoking gun. It turns out not so much. Since we know the 1000-calorie rule has lost favor, we knew weight gain wasn’t that instantaneous. Ok, maybe you would gain a couple of ounces but not up to 4 lbs from having some extra calories over a weekend.
The Bigger Picture
It would be easy to simply place the gain on the additional food. We did that at first and tried lowering our calorie intake because math is math. After a bit of time with no changes, we saw no differences. We decided there had to be more at work than just food. After thinking about it we realized our weekly routine was drastically different from our weekend routine. Some things we noticed the differences and changes:
- Water intake was lower.
- Physical exertion was higher.
- We drank more alcohol on weekends.
- Sleep patterns were disrupted.
- We ate food that was higher in fat and salt.
- As physical exertion increased so did hunger which pushed our calorie intake higher.
- A completely sedentary pattern of traveling for 3-5 hours either via car, plane, etc.
How this happens is pretty easy and it isn’t always obvious. Let’s say we get up early for a raft trip. We spend a day in hot weather and probably don’t drink as much water as we should to compensate. For food, we bring some salty snacks like jerky or nuts that can survive the warm day. Getting in and out of the boat, going down the river, etc. uses muscles in ways we don’t usually use them. That’s just the day.
After the trip, we stop at the local restaurant and wolf down a huge burger to compensate for the light eating day. That night we would sit out late on the deck have an extra glass of wine or beer and reminisce about the day. The next day we would be starving as our bodies are now repairing muscle on food that probably isn’t balanced. Let’s face it, it wasn’t the kale chips we would be reaching for at that time.
Our Reality Check
We tried changing up our food to be ‘healthier’ but it didn’t help. Ordering a chicken footlong from Subway instead of a big burger didn’t help. Oddly enough, we noticed lower weekend gains when we ate fried chicken and jo-jos as an emergency meal from a gas station hot case than we did trying to eat healthy choices. For us, it still was about controlling portion size and finding hidden calories such as are in sports drinks.
As we monitored our weight bumps, we would occasionally see the opposite result. There were weekends when we would have the exact opposite result. We would start the weekend high, and then, magically, find our weight the same or lower after the weekend. As we dug through our data we found the weekends we stayed with smaller portions, we had less dramatic fluctuations. There was more to it, however.
At first, we thought it was the extra calories which included more salt and fat. We also theorized it was due to additional calories. Sometimes we thought it was the extra physical exertion putting our bodies in ‘threat’ mode to store calories. In some ways, we felt these were all contributors however not any one of these on their own seemed like a true ‘smoking gun’ to point at as a cause.
Want an Answer?
We do too and we have a theory but no simple answer. While not doctors or dieticians we were pretty sure it wasn’t simply the calories we ate. We did some experimentation and research and found a correlation between keeping our calorie intake moderated to what we have during the week and the weekend. Shocker, correct? Not really. It didn’t tell the full story and we still had some fairly large swings in weight despite modifying our eating habits.
We noticed we could eat more and still not have our weekend ‘bump’ sometimes. On those weekends we consumed extra fiber and made sure we consumed water. Hotter weather and alcohol seem to also contribute to the bump. The paradox was we were expending more calories, eating only a little more, and gaining 2-4 lbs. It didn’t make sense.
Your GI Tract
Our GI tract is responsible for moving everything we eat and drink from inlet to outlet so to speak. Most of us have heard it takes anywhere from 6-24 hours to process our food. We know this to be true since we get hungry sometimes fairly soon after we eat a meal. If you have ever had food poisoning or the 24-hour flu, you know symptoms show up rather quickly. Those numbers are both less than a weekend correct? Yes, but what we think of as digestion is only part of the process.
For some people, the full food ride from the fork to the bathroom can take between 14 and 73 hours according to Healthline. That means whatever you have eaten may stay with you for up to 3 days. Like any machine, when we are operating routinely, with known inputs, we expect known outputs. If we change that routine on the weekend by increasing load (eating more) while decreasing lubrication (water and fiber) we can’t expect the routine processing times.
That is our Empirical Theory
Let’s play our raft adventure back and see how this can happen. In our example, hotter temps and lower water intake can increase digestion time. Having salty snacks that are low in fiber, high fat, and protein can cause digestion to take longer. The use of alcohol can cause dehydration as well. All of this can slow digestion. We then add more calories in the form of a burger and fries than we are used to processing. All of that can cause our GI Tract to come under additional pressure and slow down.
If you are carrying extra weight on Monday and Tuesday after a weekend binge this is one plausible cause. As we started to see this pattern we became more focused on how to stay hydrated and eat more appropriately when on the road or out doing our sports. We tried to keep as much of our routine, well, routine as we could. Most importantly, we learned to keep hydrated and get more fiber to help mitigate the ‘weekend bump’.
This is still an ongoing experiment for us. When we can come up with more concrete findings we plan on updating this post. Until we do, do your experiments and research. At worst, you will find what is causing you that weekend weight gain in your situation.
Ewww…gross
We are biological creatures with biological processes. It is neither gross nor pretty. What we are talking about is something that is part of being human, animal, and most other living organisms. Digestion is simply the breakdown and separation of food into what we need and what we don’t. Sometimes, you have to simply be ok talking about it so you can understand its effects on us.
Wrapping up
We talked about how the GI Tract is impacted by changes in routines. We have also drawn an empirical correlation between GI Tract health, changes in routine, and weekend weight gain. In the articles we have linked, there are many steps on how to avoid the ‘bump’ so we won’t re-iterate them. While there is no quick answer, this post has given some insight into one possible cause of our weekend weight gain. Do your research to decide if that is what is affecting you.
