See how the 5 Day Formula works
Watch Jason explain how delicious food, meal timing and movement work together.
Feel full—not deprived
Learn which foods help satisfy your appetite, then plan delicious meals you’ll look forward to eating. Eggs, salmon, a burger bowl: weight loss doesn’t have to mean a miserable dinner.
Get freedom from food
Stop drifting from breakfast to snacks to a late-night bite. Choose when you’ll start and finish eating, with room for dinner with friends and the life you want to enjoy.
Feel better in your body
Use food and meal timing to support fat loss, then build strength with short workouts. Aim for a slimmer waist, more energy and the confidence to feel good in your own skin.
The weight comes back. The frustration stays.
You’ve cut calories, followed food rules and pushed through hunger. Maybe the weight came off. Then the diet got too hard to keep up, and you were back where you started—with clothes that still felt tight and another reason to doubt yourself.
I saw this with my coaching clients: they weren’t just unhappy with a number on the scale. They felt old, tired and unable to do what they wanted with their children. Losing weight mattered because they wanted to feel strong and enjoy their lives again.
That’s why the Formula starts with making weight loss more enjoyable. You’ll learn how to satisfy hunger, choose food that supports fat loss, and give your day a clear start and finish for eating. You still have to do the work. But suffering isn’t the plan.
The best diet is the healthy one you’ll stick to.
I’ve researched and tried approaches including keto, Paleo, Bulletproof and intermittent fasting. The Formula combines the parts I use with clients: food that fills you up, time between meals, and movement that builds strength.
Your eating window is the time from your first calories of the day to your last. Instead of jumping into a long fast, you’ll measure that window and learn how to shorten it by 1 hour. What you eat inside it still matters.
You’ll also learn weight loss biohacks: coffee, tea, a creamy Bulletproof coffee, protein and prebiotic fiber can help make hunger less of a struggle. Choose the tools you want to try. Then plan delicious meals with my protein-first food guide and build strength with Quick HITs—short high-intensity workouts that fit into a busy day.
Joe Mills, a student in my longer fasting Masterclass, described the freedom he found: “I was no longer planning or fantasizing about my meals each day, but once they came around I truly enjoyed them.” Less time thinking about food. More enjoyment when you eat.


Put the Formula to work with a group
It’s easier to put off a food log or tomorrow’s meal plan when nobody else is doing it with you. In this free group course, you’ll work through the 5 lessons together. Share what you tried, ask a question and see how other people fit delicious food and movement into their day.
A new lesson opens each day at 07:30 Thailand time. Join before October 19 at 07:30.
I’ll add 1 written check-in each day during October 19–23 to help you keep moving with the lesson. You can read and contribute at a time that suits you.
The whole course is free, with no payment and no limit on places. Lessons, group comments and written check-ins are online; there are no live calls.
Keep posting and replying through October 30. After that, you can still read the lessons and discussion.

Why I created the Formula
I’m Jason Ryer, founder of Zen Strength. After launching my coaching business in 2017, I found that many clients wanted more than weight loss: they wanted to feel better, be there for their families and feel proud of their bodies. I created the 5 Day Formula to teach the food, appetite and movement tools I’d been using with clients—without asking you to suffer through another strict diet.
