thanks, that was both humorously and well-informed to read :)

yeah i agree, plant oils specifically are very good. in the general population, for inexplicable reasons, there's a common narrative that "fat is bad", which is very very wrong.

you can and should add plant oils to your food, i for example like to pour sunflower oil or olive oil in copious amounts over any salad that i make. It both tastes good and carries the flavour of other spices more thoroughly.

(it might be worth to point out that sunflower oil is about as good as olive oil for many applications, and much cheaper. 1 L of sunflower oil costs $2 while 1 L of olive oil costs around $10 for me.)

milkshakes: where i live, the nearest supermarket sells these milkshake products for 2.50€ /bottle:

a bottle has like 500 kcal, they taste well enough and have a good balance between protein/carbs/fat content.
