“I used to eat a lot of packaged, low-calorie diet foods. I would buy the low-calorie frozen dinners all the time and just a lot of processed foods and once I started eating all these plants and vegetables, I just found my mental energy was much more clear, I could focus on my work, I felt happier, I felt less anxious. For me, it was really discovering that I felt so crummy for a long time and I realized I could eat much more of this food and maintain my weight and have more energy.”
