It is definitely worth remembering that a pound of fat represents about 3500 calories. It takes a LOT of extra eating, or a LOT of missed exercise to make up a pound of fat.
Almost certainly what you are seeing is changes in your hydration levels. This is why you really need to be keeping an eye on the longer term trend, rather than attaching too much significance to a single weigh-in.

In the morning, I weigh the lowest, so I take a reading then. Each week I weigh in and depending on what I consumed the day/ week before, my weight will be up or down about a pound.

I weigh myself first thing in the morning. I go to the gym, shower there, and then go about my day. The gym I go to is at the school I go to (grad school). When I get home, I will weigh myself. Sometimes the weight may be down a few ounces. Sometimes it's up a few ounces to a pound or so. Now, I don't weigh myself 2x/day everyday. I do it once or twice a week, if I can remember. I just like to see if there are any differences. My dr. knows that I do that. Of course, I'm also a scientist (wildlife biologist/ecologist).

I was 3 pounds up yesterday, but down only 1 this morning. In addition to high sodium for a couple of days (including yesterday's lunch), I did a strength training workout yesterday.

mine also goes up about 5 lbs in a day... sometimes more. The reason I weigh naked, after using the bathroom, first thing in the morning, before I eat lol. Lightest weight of the day :)
It's crazy to know just how many calories it takes to gain a pound of fat.... kind of makes me ill thinking about all the calories I ate to get to where I am right now

I've tracked "gains" of as much as 9 lbs in a single 24 hour period! It was all gone the next day. The food you eat and the liquids you drink all have mass... and until they're digested, their weight is added to YOUR weight. Combine that with normal fluid retention through the day, and of course you'll weigh more!
Remember that this is NOT fat gain. It takes 3500 calories OVER your maintenance range to actually gain a pound of fat. Your weight is a vital sign, like your temperature or your blood pressure. It's not a static number. No one actually weighs a single number at all!

My daughter didn't believe that weight fluctuated that much daily (they were talking about it in health) so we did a little experiment.
In one day, she ranged from 102 - 106.
In one day, I ranged from 164 - 172 (!!!).
She was lowest when she woke up & highest around 2pm. I was lowest around 11am & highest after dinner.
We deliberately ate higher sodium items for lunch. We both worked out and drank tons of water.
The next morning, she was 102 again and I was 165.5.

Your weight can vary by as much as 7 pounds in the course of a single day. Factors that affect the scale include the weight of the food and liquid you just ate, the last time you used the restroom, water retention, hormonal changes, clothing and more. It's normal for your weight to fluctuate day-to-day and throughout the day. That's why it's best to weigh yourself less often (like once a week) an preferably in the morning sans clothes and after you go to the bathroom.

I weigh myself every week or so when I go to the gym. Usually I go before lunch, but today I happened to be there in the evening, just before dinner. I weighed myself and found that I'd gained almost 2 lbs! Of course I'm discouraged, but I'm also wondering how much of that is normal weight fluctuation that happens over the course of a day.
I have not been exercising much for the past week or so because I have been sick, but I also have been eating less than usual, so I didn't expect to have gained. Any thoughts?
Please send encouragement, because this is disheartening!
