siameasy I'm in a maintenance mode.
I pretty much follow the bootcamp lite rules. I focus on low carb and high fat, with lots of water. My range of carbs on maintenance is more varied, so tomatoes, carrots, a few peas. I include small amounts of nuts and seeds and a very small amount of fruit (rhubarb and strawberry compote yesterday, with cream).
For me, on maintenance, I have one day a week with more carb - always from veg / pulses. I try to plan this in, whenever possible. So yesterday I had Egyptian Courgettes with butterbeans. I think that next week I will have some puy lentils. I do this for gut health and fibre, which at a maintenance weight (or close to it) feels important ** On the days when I plan to have more carb, I massively reduce the fat in my diet. So I avoid the combination of higher carb and high fat.
Those rules sort of help me in everyday life. If I'm out and I am tempted by bread, then I have a mental choice between the bread or the butter (can't have both), and if I choose the bread then I know that I can't have cheese for desert. OR if I've started the day with buttery scrambled eggs and smoked salmon, I know that I can't chose the lentil and chicken curry for lunch.
** NB I am close to OK weight, so I start to think that overall health, nutrition, and gut health is important. But in the words of a wise AA councillor: "you should deal first with whatever is most likely to kill you". So if reducing weight is the priority, then balanced gut health comes later.
Hope that all makes sense.
