Clark argues for a 40-50gm daily intake of carbohydrate, increasing this once your body weight has stabilised. He talks through the process (and the science) convincingly, but diverges from his earlier book by aiming this one at vegetarians and people who do enjoy pasta and rice. He suggests limiting your intake of red meat, dairy products and eggs - foodstuffs which had been advocated in the earlier work.
This book contains recipes for incorporating a wider range of fruit, grains, pasta, rice and pulses into your diet. Clark, however, recognises that you will have to start counting carbohydrates if you do so.
He explains the Glycaemic Index - its a measure of the effect of any particular food on your blood glucose levels. People tend to gain weight not because of the quantities of food they eat, but the types of food they eat. A diet rich in carbohydrates stimulates the body to lay down reserves of fat rather than burn it off as fuel - hence the weight gain, and hence the value of low GI foods.
Its good stuff, its well explained, but I cant help feeling youre better reading this book after youve read The New High Protein Diet (which Im not sure is released in the USA, but see my review on Amazon.co.uk). The two do complement one another. The earlier book, in fact, is better in its explanation of the science. In this latest work, Clark includes case studies of patients of his who have experienced weight loss as a result of his diet. The case studies are too clinical. They contain phrases like, a reduction in LDL by 23 per cent from 4.06 to 3.11 mmol/l. Its hardly inspirational stuff unless you like playing around with calculators and statistics. You sense hes trying to leverage his argument, to convince you, trust me, Im a doctor.
