That's right - only 1 ONE thing. These days there are 4 food groups: Protein, Fat, Carbohydrate, Highly Processed Foods. Stop eating the fourth "food" group: highly processed foods, and I promise you the weight will melt away, your skin will be radiant, your digestion system will function well, inflammation will decrease or be eliminated, serotonin and dopamine will increase and so will your joy and calm.
There is no potion, pill or powder that will have this amazing effect. Nor is there any fad diet that will enable you to meet and keep your health and vitality goals for all of your live-long days.
The food we eat has changed dramatically from the food our parents or grandparents (depending on your age) ate. The way we eat food has changed dramatically. To compare the 2 is like comparing apples grown in your own town to fruit flavored gummy snacks found in a convenience store. Seriously.
"Those who think they have no time for healthy eating, will have to sooner or later find time for illness." ~ Edward Stanley
