BIWI, I made your tartiflette last night, and it was heavenly!
It turns out that what Sainsbos call turnips over here, are actually swede. Confusion over. I'm not sure how low-carb friendly swedes are, but that's beside the point, it was lovely.
I have spent this morning doing a weightloss chart on excel. Over the years, I have tried lots of different things, and I have weight data at various points over the last 5 years.
I have made a chart, showing the rates of loss and sustainability of each type of diet I have tried. I'm not sure if I can post it onto my profile - I may try. Anyhow, it's interesting as I seem to lose a lot of weight very rapidly with low-carb / Harcombe, however I waver around day 40. I was on Reductil 5 years ago, and interestingly it was almost completely linear weight loss for a year. The irritating thing is that although I lose weight, I always end up putting it on again, and I think that is something that I need to address with myself.
