There is of course no perfect diet but there is one common denominator shared by almost any successful approach.
An emphasis on whole foods.
This one simple switch, consistently applied, will usually create a cascade of dietary benefits including an increase in nutrient density, an increase in protein intake, an increase in fibre intake, a boost in gut health, a decrease in energy density and a restoration of satiety and hunger signals which get so distorted by the modern cocktail of ultra-processed foods.
Whole foods include things like vegetables, fruits, herbs, spices, whole-grains, beans, legumes, nuts, seeds, meat, fish and eggs. Food that nature provides!
It really is the best diet fix there is.
