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!

Dieters fail when:

Guidelines are too strict
The guidelines of the diet they choose are too difficult to follow long term. Nobody wants to weigh and measure everything they eat for the rest of their life.
Motivation declines
They eventually feel too lousy to stay motivated. If your diet doesn’t improve your health, there will come a point when you can’t take any more.
Progress plateaus
Results stop coming, leaving them far short of their goals. When you want to lose 30 pounds, getting stuck after losing only 10 makes it hard to stay diligent.

AltShift was created with these important questions in mind:

Why does any change to a new diet protocol seem to work, at least for a while?

It doesn’t even matter which diet you choose, almost any significant change will get you some short term results. What does this say about our bodies and fat loss in general?

Why do so many diets only produce results temporarily before they stop working?

You know the routine. You start a shiny new diet and some weight is lost on the front end, maybe even quickly, but then you hit a wall. You persist for a while, but nobody can keep pushing for results that aren’t coming. What does this say about our bodies and fat loss in general?

Is it natural to eat the same way every day?

Is it even remotely possible that we evolved under conditions in which our calorie and macronutrient intake were roughly the same each day? Of course not. Yet diet after diet is designed on a daily prescription. If our bodies were molded under more varied conditions, what does this say about them and fat loss in general?

Should nutrition plans that maintain health be prescribed for those who are far from a maintenance goal?

Have you ever wondered why your fit friends can eat certain foods without getting fat, yet when you eat those foods you can’t lose a pound? Maybe being healthy and getting healthy require that we ask different questions for a while. If so, what does this say about our bodies and fat loss in general?

"It’s easy to see myself doing this indefinitely. I feel great! I haven’t had any of the ups and downs with my energy or motivation that I felt when we tried other things." Sheryl Seib was the first person to ever try AltShift and she lost 5 inches in her waist in just 6 weeks. Her results just keep getting better! *

Mark Rogers of Simply Human

"99% of the foods I eat are real "human" food -- but I never really thought about when certain foods were eaten other than eating foods that are in season. After 31 days of the AltShift, I lost 1.5 inches on my waist (that I really wasn't trying to lose) and lost about 6 pounds. On top of that, I FELT great. My training didn't suffer and I really enjoyed the variety. Love this lifestyle -- and I plan to continue it indefinitely." *

Sarah Fragoso of Everyday Paleo

"I've been in the health and fitness world for almost 8 years now and my passion is helping people get healthy - really freaking healthy - and I don't give up until I find answers. Well guess what? Jason Seib has found a really big and really awesome answer. I personally have struggled with repercussions from severe adrenal fatigue and I have to work diligently to feel good and to stay lean. AltShift has truly changed my life. I haven't had this much energy in years. I'm recovering from my workouts better, I'm lean without having to "try" so hard, and the shifts just feel rhythmic and natural and not like "work" or a "diet". I'm so glad that Jason put his awesome knowledge to work and stepped outside the safe little box we tend to live in created a plan that makes so much sense and gosh darn it - it totally works!! Alt Shift is my new normal and I'm excited to continue to help others find health and now I have another amazing tool to help! Thank you Jason!" *


"It’s easy. I never feel hungry!" *


"AltShift is so easy! Just about the time I start to get tired of eating a certain way, it’s time to change things up again. I never feel deprived." *


"AltShift is straightforward and simple to follow. I never get bored with my nutrition and meal planning is easy." *


"This diet isn’t hard at all. Like anything, it takes some getting used to in the beginning, but then it’s easy. There’s none of the white-knuckling I experienced in other diets." *


"This feels less like a diet and more like a natural rhythm." *


"AltShift has changed my life! One month on AltShift brought change for me and I couldn’t be more excited! The protocol is so easy to follow, fun and I never feel deprived of food choices. As a result, 1.25 inches are gone from my waist and 1.75 inches on my hips; in fact I lost a total of 4 inches total body in my first month!! Although I’m still working through some pre-menopausal symptoms, my overall disposition is improved and I’m finally getting results. My energy is fantastic, I’m sleeping great, and my strength in the gym is awesome. My skin looks fantastic too! After stopping HRT, my skin began breaking out again, but after my month of AltShift, breakouts happen less frequently and the texture of my skin overall has softened – almost plumped with youth. I feel less stressed and calm and my thinking is clearer than its been in a year. People around me are noticing how refreshed I look, they’re noticing a positive change! I can’t wait to see what the future months on AltShift bring." *


"I bought AltShift as soon as it came out and have found it so easy to follow. I've done tried so many different ways of eating for fat loss and this one seems the most sustainable. I love how it switches so I never get bored or have the temptation of bringing of something off plan. I could see myself eating this way forever - it's so easy and intuitive. I'm through my first shift and have seen results, which has not happened in over a year!" *
