Actually eat healthily for £1 per day
Eating cheaply is really difficult to do for the folks with the least amount of money to spend on food, as working is counter to the things that make eating cheaper: cooking your own meals, shopping or growing cheaper foodstuffs, having appliances to store items for longer periods or cook dried items, being able to plan meals out in advance, etc. That is the reason why convenience foods are popular. A lot of advice stories about eating cheaply often fail to achieve that goal because it is hard to do and requires a lot of effort.
