Lower carb but not high fat apparently. He's playing a very 'safe' game which is why I say he needs to get off the fence because he is in danger (?) of contradicting himself.
Edited to add.
I give you an excerpt of Dr. Moseley's book 'The 8-week blood sugar diet recipe book'.
PP 13.
"6. Enjoy your dairy products and eat more healthy fats and oils. Until recently full fat dairy products were shunned because of a misguided fear that they are bad for you. In 2014 a systematic review by the British Heart Foundation* which looked at the results of nearly 80 studies involving more than half a million people found no evidence that eating saturated fats leads to a greater risk of heart disease. In fact, they found that people with higher levels in their blood of a particular saturated fat called called margaric acid ( the sort you get in milk and dairy products) had a lower risk of heart disease. These days I encourage people to consume more fats such as olive oil, yoghurt, cheese, nuts, prawns, avocados and coconut milk. They make food taste better. They are an excellent source of slow burn energy. And, although gram for gram they are higher in calories than carbs , they keep you full for longer. Adding fat to starch food (butter to potatoes, for example), will actually slow the rate at which the starch is broken down into sugars and absorbed. Eating healthy oils also improves the absorption of the essential fat-soluble vitamins (A,D, E and K)."
