I mostly eat something different every day but because I'm Dutch there's often a potato product and always veggies involved.
There's usually a sort of pattern though
Monday: Meat dish
Tuesday: Meat / Chicken dish
Wednesday: Chicken dish
Thursday: Pasta dish
Friday: Fish dish
Saturday: Luxury meat dish (steak or something)
Sunday: Simple dish (Hamburgers or something)
When I go the bakery I usually pick up something like Croissants or some pastry as well.
Other than that it's candy, bags of crisps, fruit salads, yogurt, ice cream, soup, bananas etc. etc.
I weigh a wooping ~65kg / 140 lbs on average.
And its really hard for me to maintain that weight, I was underweight for years.
A week of flu has brought me back to 135 lbs and I didn't even skip a meal, just ate less.
It will probably take me at least a month to get back that lost 5 lbs.
