Like Firestorm, I have to be cautious of obsessive behavior so I measure my waist and hips once per month and I'm now taking a monthly "mug shot" for comparison as well.

Since I allowed an "open eating season" I hoped to maintain but in fact I lost an inch off my waist and my face is ever-so-slightly leaner.

No need to dread the holidays next year!

Spent a week in a non-paleo household, not cooking for myself. Suffice to say, I didn't eat paleo; at all. My digestion took a hit, but after 3 days back, that's normalized. I ended the vacation up 10 pounds, but know much of that is carb weight and sodium weight, and have lost all but 3 of it so far. Those 3 will probably take a week or two more of normal paleo diet to shed. All in all, I felt like I enjoyed my vacation and time with family, and that's what matters most.

Gained 5 pounds of mostly muscle, nice Christmas present :)

I maintained my weight through out the holidays. I treat Paleo as a lifestyle not a diet. So my eating habits didn't change due to the normal holiday feast that take place in Nov and Dec.

The holidays per se weren't too much of a problem for me, so I rather doubt that I gained while I was with family. However ... I have been having a bit of a problem being home, as I've been finding myself eating a lot of stuff before starting some sort of whole 30 or junk-free January. For me at least, this kind of kick-off to the year may be more trouble than it's worth.

I haven't hopped on the scale and don't intend to until I've been back on track for a week. I want to smooth out any scares that are water weight related.

I always end up slightly undereating over the holidays because I have less control over food choices; suffice to say, I probably lost a pound or two.

My salt intake also naturally plummets because I tend to salt the hell out of my own meals.

No change. Well, small change: I managed to go down about %1 in body fat, and up 1.5% in muscle mass, which might actually just be a roundoff error in my favor from the fat measuring scale, but time will tell.

That's because I kept to what I normally eat, +/- a paleo version of a pumpkin pie and some excess booze.

Last year, between September to January, I would up gaining about 27lbs between a Cruise, Thanksgiving, Xmas, New Years, and an early VMWare class that had catered breakfasts, lunches, and cookies for snacks at 3pm.

I don't weigh or measure. I have a tendency to obsessive behavior, and feeling bad about myself if I perceive that I've 'failed' somehow, so I just try to trust my body and listen to what it's telling me... I tried to eat to appetite, not eat too much stuff that would set me off, and stay a little active. This morning, I put on my 'skinny pants' -- the pair of pants that immediately tell me whether I've been lax about my diet -- and they fit with enough extra room to pretzel myself in them to get my ZEDs on, so I think I did OK.

Maintained for me. I don't use a scale but looked the same and nothing fit weird. I kept to my workouts, was in my CF joint for a Christmas WOD - Hero DT and swimming in the Atlantic Ocean on NYD.

Some married's adopted me for both the Eve and The Day. They are all very aware of how I eat and made sure that I could eat everything - they just adapted crispy veg and plantain chips instead of the bread and crackers, all other items were game on or I wasn't interested. Even the days leading up + Hannukah it was fine. Kept to workouts and good sleep, nothing nuts.

Same for NYE but I was home and had a mini-picnic with my pup. All my good food upped a few notches with a little hard cider. I walked to watch fireworks from the deck of another set of marrieds and they had a plate of prime rib and shrimp cocktail waiting. I think everyone finally gets it now.

It was easy, you know? I'm so used to eating this way now that it's all just another day for me. Just adapt if needed. Now - if there had been pie.. that's a whole 'nother story.

I maintained. I don't remember overeating at any particular meal. So many people I know were to busy to do the usual holiday baking, so it was relatively cookie-free, which is unusual. I did have have some foods with wheat, so I am recovering from that.

2011 was my first year going paleo, and I was very pleasantly surprised that even though I gained a few pounds during the holiday, I was able to shed the excess weight very quickly.

I think part of my success comes from repairing my liver and intestines as part of my transition to the paleo lifestyle. When I began the paleo diet, I completed a detox program and continued with a milk thistle supplement for a month to restart my system. It was the best thing I've ever done for my health because I was really sick and didn't know it. I've concluded a healthy digestive track is the key to weight loss.... and just being healthy in general!

Another trick I've used to shed 2-3 pounds in a day is fasting or being really strict about what I eat the next day. If I gorge horribly, I figure the best thing is to fast or eat totally clean afterwards.

Paleo is the only diet where I've been able to cheat on occasion and still loose weight, or at least keep it in line. My relationship with food is far improved and I don't loose control like I used to.

I lost! A first for me at this time of year. Down 4 pounds in the past week and a half. I had some chocolate but no grains/starches whatsoever.

I more or less broke even through the holidays, thanks to accommodating parents, time to hit the gym, and keeping my cheats to christmas day only. Now that I'm back in the swing of regular life, I'm doing a pretty tight Whole 30 and I already feel better 3 days in.

The weirdest thing that happened is that I took a long, steep, and fast hike with my dad, and and we took dense fruit and nut snacks with us as fuel. This was a compromise, he usually fuels his hike with junior mints (and he's a beast so I can't judge him). I made dried fruit and nut "bars" in the food processor instead. The hike was fine, but by dinner time that night I was ravenous, cranky, and totally out of sorts about my food choices (basically, my pre-paleo self). Next time I will trust my fat-adapted instincts and stick to jerky, pemmican, eggs!

The best thing about the holidays is that I've managed to capitalize on everyone's new year's resolution attitude to "recruit" some friends to do a Whole 30 with me. Its always nice to have friends in the fight ;)

I had some grain in a sauce while out at friends. I felt not good after. Friends know that I am paleo; hence they cook plain foods (mostly) so that I can just eat what I am able to eat.

I've gained two pounds just from adding a moderate amount of starch and fruit (pomegranate, potatoes, nothing crazy) and eating more fatty meats than I usually do. I feel horrible, fat, triggered, ready to do stupid things to kickstart the weight loss again.

I lost a couple of pounds, which was quite a surprise. We had rather a lot of wine at dinner for several nights in a row, and way more desserts than we usually eat. (Paleo desserts, though.) I thought for sure I'd gain weight, but no.

I've been on a slippery slope since I baked cupcakes for my daughter's class the day before Halloween--it's been off and on Paleo for two straight months. As a result, I'm 4 to 5 pounds up (155/156 to 160). Started the Whole 30 yesterday to kick myself back into gear! (And, like Molly, I recruited some friends into the Whole 30! Woohoo!)

I maintained using minimal cheats, and some 16/8 fasting protocols.

When given into temptation, I ask myself, "Is it worth it? Is my enjoyment of this particular _ going to trump how crappy/ew/meh/guilty I will feel after?

Worked pretty well. But am craving sweets sometimes.

I haven't weighed myself yet (tomorrow at work), so I don't know weight wise how I did. I know my eating wasn't the best. I gave myself the ok to make bad choices if I wanted too. It happened more than it should, but I was also aware of how it affected me. The bloating is back, and the over-all tiredness. Today I started a month-long sugar detox, so that should put me back on track. This was my first Christmas/New Year's following Paleo, so I can use this experience and be better prepared for future holidays.

I ended up dropping about 3/4 pounds right before I left for home...but then came 3 days with the family of eating and drinking THEN I went to Atlanta to work the Chik-Fil-A bowl and Auburn so graciously gave us per diem to feed ourselves...Let me tell you, a week of eating out in Atlanta is expensive and very filling. I tried to eat as Paleo as possible (salads, steak, fish, greens, coffee with cream) but those holiday cocktails will get to you ;] I worked out almost every day(I took 2 days off I believe), light workouts because I was without a Crossfit box, and I am back to where I was before I lost those few pounds...Yesterday I started a 7 day fast consisting of water, tea, bone broth, a BCAA supplement for PWO, and a sip of apple cider vinegar here and there to kill any hunger cravings. I'd like to go 14 days to become fully ketoadapted, but Ill go a week first and see how I feel.

I maintained (much to my surprise). Some days were paleo cooking and baking, others were non paleo if I was at other peoples houses. I have been paleo since september and I think my metabolism has finally started to heal itself and function normally, hooray, which is the main reason I believe I didn't pack on the pounds. It's great once you realize your body has truly began the healing process.

I'm up 3 pounds. I did eat more paleo-friendly carbs and wine than normal, but I think the gain mostly came after I got home and was sick with a nasty cold (First time since going paleo and all I can think of is air travel and lack of control over my environment). That plus getting unintentionally glutened over New Years seems to have bloated me up. But I had grass fed steak and eggs for breakfast and I'm planning on starting a complete immune/gut healing 30 day plan by the end of the week, so I figure it will be gone quickly.

Maintained, which was a bit of a surprise as my clothes feel tighter. Probably gained fat and lost muscle. Back to the gym.

Gained 5 lbs. and went off Paleo for for pretty much a month. :(

It is really hard to go back home during winter break from college. I went a week trying to stay Paleo, but every time my mom would make dinner I'd tell her I couldn't eat it. She'd get frustrated, ask why, I'd list all the ingredients I couldn't eat, and then she'd get worse. Even trying going with her to the grocery store to get what would be good. They didn't care what I ate and wanted me to stop worrying about it, so when you are surrounded by that 24/7, I just started not to care myself. I totally lost it. I just wish I could get back on. I still read Paleohacks, paleo books, and keep updated, but I'm so scared of failing again and I don't know where to start, so I'm not eating well. Blahhh.

I don't really know how I did it but I lost 1 single pound.

I ate wheat and sugar and PUFA like a madwoman, gained five pounds, and am still dealing with the after effects -- my joints hurt, my stomach hurts, even my BONES hurt! Not to mention the crazy mood swings (whee!), foggy brain, and clumsiness, and how lovely the puffiness on my face is. Gorrrgeous. ;)

It's the first time I've really gone whole-hog (wait - whole hog would be Paleo), off-the-rails SAD since starting Paleo almost a year ago, and was it worth it? For the most part, No, and I absolutely won't do it like this next year.

My dad's homemade Strawberry Shortcake, though -- that I will do again next year. That was worth it. Mmmm.

I noticed a huge uptick in Paleo tweets bemoaning the holiday cheats. I was pretty surprised at how many went off the rails.

I'm no saint, but I'm lucky in that all my family and friends know that we won't eat something that's totally off-plan like pasta, pie, or chips. It also helps that I'm the main cook for a small family. We don't have herds of extended family bringing their dishes over to tempt us.

All meals and treats I planned were Primal. For example, xmas dinner was prime rib, buttered carrots, and creamed spinach. When going to someone else's social event, I made sure to bring a snack and a dessert-y item so that we wouldn't feel left out. I did have a little refined sugar but only 2 run-ins with a small amount of gluten, 1 intentional and 1 not.

Preparedness is key. Don't expect anyone else to take care of you. Even when I travel, I make sure to have a stash of food. I mean, give in as much as you're comfortable doing, there's no right or wrong here. But for me it comes down to two things: 1) I'm an ambassador of this lifestyle and how am I going to convince skeptics when I'm stuffing my face with Ho-Hos, and 2) I feel like shite the next day and I don't want to feel like that anymore. There's no croissant in the world worth that. I'm over it. I just don't really consider it "food" anymore.

So, to answer the question :) , I maintained. Actually lost two pounds, but it's within the range I consider normal for me. I felt like I got to indulge but I didn't go overboard.

Even with 10 days of flu which kept me out of my holiday festivities I managed to gain about 3 lbs. I stayed mostly paleo (accept for half a small bag of Funyuns that jumped into my mouth when I was busy doing something else) but my carbs went up as I had planned hence the weight gain. I enjoyed a lot of dried fruits (Whole Foods had some awesome fig and walnut and almond and date cakes that were totally worth the splurge.) Had a couple of gluten free cookies and some not-as-dark-as-it-should-be chocolate to round things out. Oh and some soaked oats which was again so worth it. So I'm happy with how it went down. The pounds will be gone within a week I think now that I'm back on the straight and narrow. No regrets whatsoever.
