Trust me you will be in ketosis as you haven't broken any rules, it defies the laws of nature not to as our bodies will naturally just turn towards our fat stores!
haha you should sell those 40 cans, and buy a weeks supply of lipotrim! lol
Enjoy your shopping trip, and look at all those clothes that you will be wearing after you have dropped down to your weight, it will make it worth it. Drink a nice cup of black coffee with a sweetner if you find it difficult eating around them, as it may help supress the appetite or atleast mean you can distract yourself whilst they eat... think about the sensation of the coffee touching your lips and literally just do some visual meditation to make the time go by (lol well this is the kind of mindfulness tips that you would tell someone with anxiety difficulties) haha or you can just be a soldier and be super strong, not eat or drink anything and act casual.
I have been a bit of a soldier, yesterday I purposefully walked past the take away shops just to get a wiff of the junk, and alhtough it seemed excruciatingly nice... I am one of those people that are extremely strict when it comes to sticking to rules,,, well certain rules
the smell was so nice I even considered just going to a take away and just standing there "testing myself" but really I think it would be more just to smell the nice foods hahaha
anyway have a great day and report back!
