History:
Balanced nutrient ratio diets hit the scene in the mid to late 1990’s. Instead of cutting out fat or carbs completely this theory suggests that you eat each major macronutrient at approximately the same ratio. The most common style was to consume 30% of your calories from fat, 30% from protein and 40% from carbs.
This was a drastic change from the mainstream diet advice of approximately 70% carbohydrate diet mixed with 10% protein and 20% fat. Considering this as the guideline at the time you can see how changing the ratios to 30‐30‐40 would be a big shake up.
This theory borrowed from the insulin control concept from the low carb theory but threw away the notions of the low fat theory which had proven to be a bust by at this point.
Proponents of the balanced nutrient ratio diet teach the consumption of the good fats that helped reduced heart disease risk.
Increasing protein consumption from 10% to 30% of the diet was an easy recommendation to make as nobody could find anything wrong with eating more protein, and compared to carbohydrates proteins cause slightly more calorie burning and satisfy hunger better.

The balanced nutrient ratio diet theory correctly assumes that people will not want to eat very low carb or very low fat for too long until they give up. This style of eating borrows from the insulin controlling aspect of low carb theory as well. In this case the reduction in carbs is not as big as the reduction called for in low carb theory. This would allow people to still eat a healthy amount of fruits, veggies and grains without feeling deprived of carbs.
By now most people are well aware that there are good fats and bad fats and that we still need the good fats in a healthy diet. Increasing the recommended fat content from 20% to approx
30% of total calories isn’t that big of a jump. The increased fat is also meant to be ‘good fats’ which makes it much easier for people to
