If you go to SW things might work out wonderfully well. However if you are planning to eat rice, potatoes, pasta etc - and even fruit and higher carb vegetables - then you may end up right back where you started.
I can't lose weight by eating even a normal but reduced number of carbs. Many can, because they don't have my extreme carb sensitivity/addiction.
If I had a nut allergy I would avoid nuts entirely. Likewise a strawberry allergy, or even a Penicillin allergy. I now view certain carbs, the ones that trigger slip after slip and usually lead to mad bingeing, as 'allergens'. They affect me very badly indeed and any pleasure I get from eating them is counterbalanced by the cravings, the hunger and the eventual weight gain they cause.
Please think carefully before walking away from ketosis. And please also watch that cream intake! 2 Tablespoonsful per day maximum provided it does not stall you. It ain't easy! ha ha.
Glad your weight is still going down hun x
