Low-carb really suits me too. 15 months ago, I gave up carby food and refined sugar, pretty much completely. I now only eat unprocessed food. Diet consists of lots of veg, some fruit, olive oil, cheese, eggs, full fat greek yoghurt. These can be made into all sort of delicious things, and I've never enjoyed food more.
I've lost two and a half stone, look younger, my are eyes brighter, I'm full of energy and I don't get all the weird aches and pains I used to get. I actually want to get up in the morning! It's been life-changing for me, to he honest.
I used to feel like a trash can, all the rubbish that went into me. Mentally, I feel so much sharper and on top of everything. Never been happier. It's worked for me, though I'm not saying that it would work for everyone. But for me, low-carb / no sugar is definitely it.
