I worried about the example dieting would set my teen and pre-teen dc. However, by eating Low Carb High Fat, and being the main cook at home, I am able to eat the same food as them, with them, at the same table, at the same time. I just have half a potato and loads of greens with my meat, for example, and a generous spoonful of mayo.
The dc see both parents enjoying a range of food. They get an alternative view on 'healthy eating' to the carb-heavy, anti-sugar, anti-fat one that is promoted elsewhere.
They do not see any food demonised: they see dh loading up on carbs when he is fuelling up for a long-distance run. They get chocolate bars and Full English when out hiking. We have desserts and treats. Carbs have their place.
Fat is demonised by conventional thinking. They see me using it mindfully as a replacement for carbs, because I am not as physically active, therefore do not need carbs.
When they bake, I have a little portion of their creation. Nothing is demonised or forbidden. Diet is not about control, but about fully enjoying food in the best balance for each individual.
I would say that my dc eat a bigger and healthier range of food in the last 4 years since I discovered LCHF.
