I agree with teaser's point and I would add that due to the fact that no one person responds to a designed diet in the same way, we need to understand the health implications of consuming types of fats, proteins, and carbohydrates against a backdrop of metabolic tendencies. There are those who can do very well with a low fat approach, however, those that do well also are inclined to have a well-designed WOE based on eliminating nutritional gaps to maintain health. It's the same issue for LCHF as well.

To attempt to achieve a universal dietary guideline for everyone is folly. To understand this fact and implement a varied approach with choices would be the first indication that the DGA recommendations could be of value in the future. In the past, members of the DGA advisory board have had agendas or are named to that role for the purpose of implementing a specific food agenda. This must stop if we are to make any progress in making the DGA process valuable for all.
