For the longest time I thought I was eating healthy. A piece of fruit each day and vegetables with dinner. I was really active with biking, yoga and hiking, but not losing any weight. Carbohydrates secretly sabotaged my diet. Then last January, I decided to turn to more of a protein-based diet. I did lose weight fast, but after a discussion with a person who eats a plant-based diet, I quickly learned that high protein was not sustainable or good for my health in the long term.
