But when people refer to ultra-processed food, what they're referring to is Nova Stage 4.

And that stuff kills your gut microbiome because it doesn't contain anything that they can feed off.

And if you're living off that stuff, they're just going to die of starvation, these poor bacteria.

So when we're talking about the food that we should be eating...

80% of our food should come from Nova Stages 1 to 3, and with a particular focus on Stages 1 and 2.

So whole foods, minimally processed foods, cooking from scratch.

The more plants you get into your diet, the better it is for your gut, the more fibre.

Fibre is the key word when it comes to gut health.

The idea is that we should be getting 30 grams of fibre a day.

Basically, the more plants you get into your diet, the better.

Yeah, that's exactly right.

It's like going out with a group of friends and you're all choosing different things off the menu.

Your bacteria are exactly the same.

They all want a different plant.

Yeah.

And then they like friends as well.

So add to the friendship group by having a probiotic.

Feed them.

Feed them and get them to multiply.

How does gut health affect our ability to lose or maintain weight?
