My job and social life is quite busy too. Airports, service stations and to a certain extent hotels etc are a nightmare to eat well, which for me means whole foods, nothing much ultra processed and very low added sugar.
breakfast almost always savoury. Even if it needs to be something a bit “weird” or if I need to find an actual supermarket the night before. I’d eat a plain chicken and salad wrap over a pastry or big bowl of cereal. At home it’s mostly eggs or mixed beans/ lentils with some veggies on toast
lunch at conferences etc I just don’t take the bread or pasta or desserts usually. I’m not saying never, but like 90% of the time I’m eating the salads and veggies with meat or fish.
dinner mostly like lunch. I don’t drink alcohol during the week, but at the weekend I don’t stress about having two glasses of wine and maybe a G&T or martini too if it’s been a long week 😅
i also know that when I’m travelling I’m out of my regular exercise routine and likely eating not as well, so even if I feel a little hungry in between meals, that’s fine 🤷♀️ I know I’m not going to wither away before dinner! So I just don’t reach for a snack.
if I’m home then it’s much easier and I guess I just stick to what is termed a “Mediterranean diet”. I think a massive help to me is I just don’t have a sweet tooth so it doesn’t feel hard not to eat cakes and biscuits etc.
