Hi Jill,
I think that ultimately it is up to you to decide what you are happy with.
For me to start off with when I first went on keto, I had a cheat day once a month, then it became only on very special occasions & far less frequently, partly because I felt like rubbish for about a day afterwards, (carb headache) & partly because I didn’t want to regress too much.
When I restricted myself to super-special occasions, I enjoyed my indulgences more when I did partake but also didn’t beat myself up too bad as I knew it was going to be a long time until I did it again.
I made a bigger exception for myself whilst overseas in Europe with my son & his Mum in December so I could try some of the local food/drink, eg German beer, Italian pasts, pizza, etc - turned into gelato every night + loads of carbs for the last two & a half weeks. I ended up putting 5kgs back on even though we were walking a lot which I sort of expected. Lost it all in the first 4 days back on keto. Probably better sleep, etc too but I did feel strong cravings for a while when I got back. For about a month I was allowing myself artificial sweeteners which is something I normally avoid so that I could wean myself off the carbs bit by bit.
Before I went on keto, I wasn’t aware of any food cravings but now I am aware that I was definitely addicted to carbs.
How far you can go without it becoming a problem for you is something you’ll have to decide for yourself. I think of myself as a recovering carboholic. Carbs once in very long while is OK for me but semi-regularly definitely won’t work for me. I wouldn’t be happy with the results & feeding my old addictions all the time would make it very hard for me.
Some people have problems with alcohol & have to refrain from drinking too often, others have to be total teetotallers to stop from being an alcoholic. Alcohol was never something I craved but carbs were so I know that I need to be careful & know my limitations.
Have a think about it & see what you are happy with, whether it be the weight, health, cravings, etc & be realistic about whether it is going to be sustainable for you. Don’t forget that carbs can be seriously addictive…
This may sound a bit silly seeing as you are a psychotherapist but when I am talking to my son about how he should be acting, I ask him to externalise it & say to himself “If this was one of friends, what advice would I give them?” Sometimes it can be a bit easier to think about something more rationally if it doesn’t seem so deeply personal.
Good luck with all. Just remember at the end of the day that it’s about what you are happy with, not anyone else.
