Is porridge good for weight loss?

Porridge is one of the most filling breakfasts for its calories, thanks to the fibre in oats. On its own it is low in protein, so stir in some Greek yoghurt or protein powder, or make it with milk, to keep you full until lunch.

Toppings

A teaspoon of honey adds about 20 kcal, a tablespoon of peanut butter about 95, a sliced banana about 105 and a handful of berries about 30. Toppings can easily double the calories of the oats.
