“Whether you’re taking your first steps on this path to wellness or recommitting yourself to success, let A Plant-Based Life(AMACOM Books, 2016) by author Micaela Cook Karlsen be your guide. Her program enables you to set your own pace and stay the course—without relying on willpower. Drawing on personal experience and the latest research, she reveals how to: find and sustain your motivation; gradually add more whole, plant foods into your diet, crowding out less nutritious fare; break old food addictions and establish new habits and translate favorite recipes to create delicious, nourishing meals. Especially valuable are directions for navigating roadblocks. Here you’ll find strategies for getting family members on board and for allaying friends’ concerns about your food choices with evidence-based nutrition information.” — Excerpt from Mother Earth Living

amaze-magazine“Most diets fail, as research shows, due to the rigid rules people impose upon themselves. Vowing to never eat a favorite “forbidden” food again fuels feelings of deprivation. Too often when dieters surrender to temptation, the guilt drives them to go on a binge eating spree and, eventually, just give up. The good news is there is a more sensible and satisfying recipe for adopting a healthy plant-based diet. Rather than concentrating initially on what NOT to eat, simply add in more whole plant food than you’ve been eating.” — Excerpt from Amaze Magazine
