Easy Weekend Weetabix Cake (Fatless and High-Fibre)

Weetabix Cake - Fat Free & High Fibre (and delicious!)


This fat-free, easy-to-make Weetabix cake sounds too good to be true doesn’t it? Well, I promise you it isn’t. It doesn’t even require a lot of mixing–it’s that easy. Really, Mr. Weetabix does the hard work here, acting as a superb glue for the rest of the ingredients (so you need no butter), he adds a delicious taste and a high dose of fiber too.

No cake is ever going to be classed as a health food, but if you’re going to have a cake then at least make a healthier version. A slice of this will fit in your lunchbox just perfectly.

What’s the Big Deal with Fibre?

intestine diagramSo, you probably hear a lot about why fibre is so good for us, but you don’t really know why. Well, probably most grown-ups don’t either! To understand better, let’s take a look at how our bodies process the food we eat.

Once food reaches our stomach (tummy) it next gets sent to the small intestine. The small intestine processes our food, and anything that can be absorbed into our bloodstream gets taken care of here–such as sugar, for example. Anything that our body can’t absorb then gets sent on to the large intestine. The large intestine processes what is left of the food that our body can’t use, and  it turns it into… well… poop.

Fibre travels through both the small intestine and the large intestine, making sure they stay clean–this helps to keep our insides nice and healthy. If you eat a good amount of fibre, then when it’s time to go to the toilet, fibre makes it easier for you to… well… poop.

So, as you can see, fibre is a really important thing to have in our diets.


Where is the Fibre in Weetabix Cake?

In our Weetabix cake, the Weetabix itself has a good amount of fibre, and the dried fruit (sultanas, raisins, etc.) is a good source of fibre too. So these foods aren’t only yummy they are good for our bodies too!
