The Radix 5:2 Vitality System is designed to support weight loss while helping maintain muscle mass.

Traditional weight-loss approaches often reduce overall food intake without protecting protein intake. This can increase the likelihood of muscle loss, especially for adults over 35, when muscle becomes harder to rebuild.

Radix takes a different approach. Both Light Nutrition Days and Foundation Days are built around protein-centred meals, helping you maintain a meaningful protein intake across the week. When combined with regular resistance training, this supports the maintenance of muscle while body fat is reduced.

The goal of the system isn’t just a lower number on the scale. It’s weight loss that still supports strength, energy, and long-term vitality.

No. The Radix system is not a fasting protocol.

Traditional 5:2 approaches often involve very low-calorie “fasting days,” sometimes with only one small meal. Radix replaces those with Light Nutrition Days that provide structured, nutrient-dense meals across the day.

Instead of skipping meals, you follow three planned eating occasions built around protein-centred Radix products. This creates a reduced energy intake while still supporting normal physiological function.

The focus is on structured, functional nutrition, not deprivation.

Yes, light to moderate training is generally suitable on Light Nutrition Days.

Many people continue with:

• Walking
  
• Mobility work
  
• Light cardio
  
• Technique-focused sessions

However, higher-intensity or heavy resistance training is usually more comfortable on Foundation Days, when energy intake is higher.

The system is flexible. You can schedule your Light Nutrition Days around your training routine so that your more demanding sessions fall on Foundation Days.

Missing a Light Day occasionally isn’t a problem.

The Radix 5:2 system works through a weekly rhythm, not perfection. If you miss a Light Day, you can simply:

• Move it to another day that week, or
  
• Continue with your normal schedule the following week
  

Consistency over time matters far more than any single day. The goal is to build a repeatable structure that fits your lifestyle, not to follow a rigid plan.

Yes. In fact, the system is specifically designed with adults aged 35–65 in mind.

As we age, maintaining muscle mass becomes increasingly important for:

• Strength and mobility
  
• Metabolic health
  
• Long-term independence
  
• Energy and resilience
  

Many weight-loss approaches do not account for this. The Radix 5:2 Vitality System prioritises protein and nutrient density to help support these foundations while body fat is reduced.

For best results after 50, it’s recommended to:

• Maintain regular protein intake across the day
  
• Include resistance or strength training 2–3 times per week
  
• Follow the Light Day and Foundation Day structure consistently
