Try substituting quinoa for rice, eat avocado, chia seeds to help you feel full. Chia seed ‘jam’ is tasty and useful, just defrost a bag of frozen berries mixed with chia seeds to absorb the moisture. The chia forms a kind of jelly which binds the fruit together, the jam can be eaten with yoghurt or breakfast ‘cereals’ (I make quinoa or buckwheat porridge)

Don’t make smoothies etc but eat the whole fruits instead.
Eat plenty of protein.
