I haven't gained any weight since 1994. The secret to my success is I haven't weighed myself since then.
There's been some hints from others that I may have gained a pound or two. The agent at the airport check in counter asking Mrs. Kuki if she had a container for the freight, for example.
Honestly.... I don't belive I gained much weight, even on the back to back cruises. I actually eat more at home than I do on a cruise.... unfortunately.
On a ship I generally have only two meals a day. At home, it seems I'm constantly putting something in my mouth. We have a lot of food available in our bar, so nibbling as I walk by is common. After dinner at home, I've invading the "nosh" cupboard all night.
In ports of call we do a ton of walking as we like to often get off the beaten path and go exploring.
So... I believe I'm the same loveable cuddly 250 or so pounds I was before we cruised<G>
