How much does the average person on a cruise gain in one week? Also,
is there a reference specifying what percent of body weight increase
is seen. We need a scientific reference.

I'm going on a cruise on September 9th, for 7 days.

I will scientifically weigh myself on the morning of September 9th,
and weigh myself when I come back on the 16th --and make a full
report!

In the meantime, here's some info:

Are Vacations and Weight Gain Synonymous? 
http://travelingtoday.com/resources/articles/weightgain.htm
..."The average weight gain on a weeklong cruise is 8 pounds, though
most of us have experienced vacations on dry land that have yielded
the same or greater results. Anytime your daily routine is interrupted
and you are confronted with the allure of foods you don't normally
eat, doled out in larger portions than you are used to, the weight you
lost the first part of the year will find its way back..."

Hi Cynthia....

I hope you have a wonderful time on your cruise :)

Thanks Steph!  

My son won it at a regional sales meeting at the new car dealership
where he worked last year, it was the grand prize out of over 400
people present, and he chose to take me. Imagine that, what a kid!

The US Surgeon General and the EU Commission definitely should require
that all cruise advertising and tickets bear warnings:  "Cruises can
be detrimental to your health;"  "Cruises may increase the risk of a
heart attack," etc.
Maybe there could be a small print proviso:  "unless you are underweight."

Have a great cruise, nonetheless, Cynthia.

And here gossip me was thinking of more Suri news.

It is reconned that you will gain fifteen ounces of body wait for
every day of the cruise therefore on the "around the world cruise" 110
days you will need to shop at least twice during the voyage

My father-in-law went on a cruise last year and spent most of the time
"feeding the fish".  I think he LOST about 10 pounds.
