"The diet plan that changed my life in 3 weeks" - The Times

"Unquestionably The Metabolic Reset completely lived up to expectations as Stephenson promised it would. I was calmer, more focused, sleeping better and my temperament was manageable and even.

The big lesson was that we can, if we wish, cross the border into the land of optimal health, and what passes for acceptable can be swapped for vibrating vivacity and hugely boosted mental clarity."


Recipe Highlights

The Metabolic Reset provides over 90 gluten, dairy and sugar-free recipes designed to support the microbiome and improve metabolism. They are rooted in the CORE and CORE+ foods from the programme, and deliver nutrient dense, plant-rich meals. With omnivore, vegan, keto, and low carb options, you'll find recipes you love to enjoy on the programme and beyond.

Eggs on toast with baby kale and sriracha

Plant Parmigiana

Broccoli rice bowl with tuna, poached egg, and Caesar dressing


Super green Thai vegetables with coconut broth

Cali-inspired harvest salad with pomegranate dressing

"Amazing programme - has genuinely changed my life."

"This programme is phenomenal and has completely changed my approach to eating. Before the programme, I was mindlessly snacking and making food choices that were not giving my body the nutrients I need... my sugar cravings are basically gone and I now gravitate towards nutrient rich foods that make me feel satisfied and stronger. The recipes are delicious and filling. Keto buns are now a firm staple in our household!"

What results should I expect?

This programme is designed to combat cravings, support your metabolism, and reduce body fat. Common results include better energy, appetite control, emotional wellbeing, and fat loss.

Can I still eat out?

Yes! There are guidelines in the e-book that help you understand how to navigate this.

Can I personalise the meal plan?

Yes, there are over 90 recipes to choose from. If you prefer to swap in other Artah recipes you are free to do so.

Will I experience any side effects?

This programme is designed to optimise your nutrition and metabolism to help you feel better. As you start to change how and what you eat, your body will start to adapt and some individuals will feel this more than others. It depends on your starting point, how much sugar you currently consume, and if you follow a plant rich diet. Common side effects at the start of your plan can include cravings, fatigue, and headaches from sugar withdrawal, however these should be short lived. If you are concerned about potential side effects, we recommend purchasing the Ultimate Metabolic Reset, which includes supplements to support energy, combat fatigue, and help with healthy metabolism.

Can I still exercise?

Yes, and its recommended! You'll find workout guidelines in the programme.

What is time restricted eating?

Time restricted eating means eating within a specific timeframe, for example, condensing your meals into an 8 hour period, and 'fasting' for 16 hours. It is a proven tool to help improve energy, metabolic health, gut health and more.
