I notice a few of you doing Lytham's Challenge are reporting "carb cravings" and/or some trepidation about keeping this going. I can completely understand this. Once you get into LCHF, you realise that the British food landscape is awash with carbs (and low-fat food). Supermarkets, restaurants, everywhere. Staying low-carb for any length of time can be a bit of a trial. The things you need are there, but they're hidden among mountains of junk.
Just a couple of a reminders:
1) Eat until you are full. In particular, you want to really stack up your plate with veg. If you're feeling absolutely stuffed after a meal, you're less likely to make an emergency trip to the all-night garage for a three-week-old doughnut or a Mars bar. Keep some snacks in the fridge that you know you'll like: Greek yoghurt (with some sort of topping) gets mentioned a lot.
2) Carbs are not evil. If you "fall off the wagon", or if you simply feel like a plate of spag bol for a change, that's perfectly OK. You don't need to feel guilt about it, or switch back into self-destruct mode because "you've already blown it, so what's the point".
As long as you've made it through the first 2-3 weeks, your body will be much more capable of coping with carbs. In all likelihood, you'll be able to go back to your normal (low-carb) routine the next day; the worst that will have happened is that your weight-loss target will be delayed for a few days. This is not the end of the world. Even if you end up having carb-based blowouts once a month, the impact on your end goal is going to be minimal or nonexistent.
