Anyone on Atkins? in Lose Before You Cruise Posted March 15, 2015 I have done Atkins in the past and yes it works short term. For me now it doesnt. I am to active doing hard core classes daily , walking 12 k a day, I find using my fitness pal more beneficial. Keeping track on everything that I drink and eat, calorie Burn etc, really opens your eyes. I gained a lot of muscle and lost inches. I feel great while eating well and having a few drinks to. It is a lifestyle change that is for sure. The last cruise I went on I payed for the boot camp plus the trx class, yes some days 2 a day. But didn't feel guilty and enjoyed the cruise. Leaving next Thursday for 2 cruises 20 days, planning to do the same. So I guess what works for one may not work for you. As my trainer says you need to eat or you won't lose. She was right.
