Hi there - just coming back to Minimins - and saw you are looking at Keto. I've been using dietdoctor.com and am lurking on the reddit keto threads. The keto thread on reddit has a really useful calculator. FB groups on this sort of way of eating seem toxic and not so supportive.
I choose low carb medium protein high fat things to eat - and track it, rather than rigid planning. I choose not to eat "white" foods - potatoes, bread, pasta, wheat pizza etc.
I had lost a shed load of weight on vlcd, and then didn't manage maintenance. When I tried to do vlcd again, I couldn't sustain it. I'm finding the low carb approach much easier.
So I aim to shed 100lbs - starting with the first 10% as that seems more manageable. I've reset my tracker - and am already 5% (a stone) down on my new start weight. So I am pleased with that.
I find it much easier than shakes as I can eat - and often things I really like, like meat, eggs and low carb veg.
I started off just eating the foods on dietdoctor's webpage.
Now I've been tracking what I eat on MFP for two weeks, staying under 20 carbs. I don't feel deprived and am rarely hungry. I'm down 16lbs since 1 Dec - 52 days. I know it may steady - however I'll be very happy if I can shed a stone every 6 weeks - I'll be c4 stone down by Xmas - that probably means size 18-20 from size 24-26 now. My waist is already down a good few inches, even though I've just shed a stone.
I'm a bit disappointed to find no lchf thread here - and also not to find old friends active here.
Atkins is the nearest to lchf or keto - and thats not so active either.
The only difference is that Atkins phases back in more carbs to find steady state when at goal, whereas hard core keto or low carb stay that way. I am thinking about posting on the diaries thread - as daily blogging here was helpful. Reading back through a single thread was good - tracking how I felt. I have weighed daily (up & down, not straight line) on MFP. So I am thinking about daily posting here or on reddit (can't have a single thread there). Not really decided yet.
Good luck!
