FAQs

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.

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.

Trusted by experts

"I use Cellular Hydration during my workouts and it has been fantastic. It's undoubtably helped my training and performance and has an incredibly refreshing taste."

Dr. Hugh Coyne

"I use Enhanced NAD+ Complex because it targets multiple aspects of NAD+ biology, supporting production via nicotinamide riboside while also helping reduce NAD+ depletion. This synergistic formulation supports both energy metabolism and longevity pathways in a way that feels both intelligent and aligned with systems biology."

"As a nutritionist and someone currently pregnant, I’ve felt great taking ARTAH’s Enhanced Fertility. It’s one of the few formulas I fully trust for both clinical recommendations and my own journey. It is thoughtfully dosed, easy to tolerate, and includes key nutrients that so many standard pre-natals miss! "
