overnight weight loss

[Chuck Koehler]

Just an update:

Today I tried to rank my first 500m row. Although I have been rowing every day for three weeks I didn't do so well. I "gave up" after 1:35 to breathe and then finished off at 1:53. I think that it would be better if I were "training" on and off, but since my principle goal is weight loss it's OK for me now.

I plan to start trying to rank before doing my 10000 meter weight control routine.

When I weighed again in the morning, I was amazed to see that I had lost 5 pounds. I thought that my memory must have been playing tricks on me, so I did the same a couple of nights later and wrote the weight down before going to bed. In the morning the scale showed a loss of over 5 pounds.

The obvious cause would be loss of water, but, even with two or three trips to the bathroom during the night, I doubt that it would account for even as much as one pound total.

I apologize for reviving a dead thread, but I want to report that I now have the answer. I had vastly underestimated the weight loss resulting from voiding. I recently acquired a digital bathroom scale and did a check last night. On three middle of the night bathroom trips plus one just after getting up, the weight losses were: 1.2#, 1.6#, 1.4#, and 0.8# — a total of exactly the 5# that I was wondering about a couple of months ago.

That may seem like a lot of trips to the younger members, but 2-3 trips a night is fairly common for us older folks. It comes with the territory.

Our bodies require a lot of water to digest and absorb food, if you are very active your less essential body functions slow as you reduce the blood flow to the organs concerned. the mots massive of these is the gut, so we can add much water to the gu in the evening before bed and then absorb this and some more (food nutrients get transferred in a solution). Also polymerising fod stores reduces the water they require (lower osmotic strength) as well as the food used no longer requiring water with it (I believe glycogen is held with 3 times its own weight of water, so 600 kcals of glycogen used overnight will be 150g and a full pound of water will no longer be required).

Add a regular erger remaining fully hydrated ready for the next session and 5lbs weight loss overnight is fully believable.
