It’s worth noting though that the focus on protein in the diet is not wholly without foundation. One reason why protein is often recommended by nutritonists is not because the protein itself is needed but because it can help with weight control. There have been numerous scientific studies (such as by the CSIRO in Australia, which developed the Total Wellbeing Diet) showing that protein does a better job of filling you up. Calories from protein may keep you full for longer than the same calories in carb or fat form. This varies by person but I’ve found it be generally true – if I have eggs for breakfast I rarely get hungry mid morning, whereas if I have cereal I do. Low-GI carbs are good too though – I also find porridge (oatmeal) and healthy muesli to be pretty filling.
