AltShift Diet by Jason Seib with recipes by Sheryl Seib


AltShift – Lasting Fat Loss at Last

AltShift works by not only asking what we should eat to be healthy and lean, but also when we should eat those foods (over days, not hours) to make the most of their macronutrient content and to keep our bodies from adapting and halting fat loss.

The hard part is keeping it off?  Not anymore!

Body Beliefs 3D cover -400h


Body Beliefs

After years of coaching frustrated, yo-yo dieting women with fat loss goals, Jason Seib has reached a firm conclusion: his job is about minds, not bodies. Poor body image, low confidence, self sabotage, perfectionism, extrinsic motivations, social comparison, a basic misunderstanding of what fat loss really is – these are just a few of the obstacles keeping so many women from achieving their goals and creating bodies they love to live in. Yes, he is a man, but few professionals of either gender could ever lay claim to as much passion and devotion as Seib has poured into Body Beliefs. You can have the body you want, but you’re focused on the wrong part of the problem and your perspective is keeping you from success. Change your beliefs so that you can change your body. Forever.
