What’s Next?


Functional Nutrition emphasizes the importance of high-quality foods and phytonutrient diversity to address clinical imbalances and move individuals toward the highest expression of health.

Our genes are not our destiny…they are our greatest opportunity. Through food, you may tap into the flexibility of your genes. The nutrients in healthy foods – vitamins, minerals, phytonutrients, botanicals – all work synergistically to help your cells express good health. It is not often the genes that are our issues – it is the effects that the environment has on our genes. This starts with the foods we eat. It also is highly dependent on how we detoxify our highly toxic world.

We encourage you to explore our nutritional services at RMD. We offer many other nutritional programs.  Please talk to your RMD providers, including:

• Medical foods
• Professional supplements
• Detox programs
• Prolon
• Fasting mimicking diet (Longevity diet)

Medical Foods

Medical Foods vs. Dietary Supplements

Medical foods are often confused with dietary supplements—perhaps because both may contain nutritional ingredients; however, the terms are not interchangeable and fall within discrete regulatory classifications.

Dietary supplements are intended to:
  • Provide supplementary nutritional support for healthy people
Medical Foods used for:
  • Compromised Gut 
  • Inflammatory bowel disease
  • Sarcopenia
  • Glucose control
  • Dyslipidemia
  • Cardiovascular support


The ProLon Fasting Mimicking Diet is the first and only meal program that has gone through clinical trials at the University of Southern California and been patented for its anti-aging effects! This 5-day meal program provides scientifically researched micro- and macro-nutrients in precise quantities and combinations that nourish you, but are not recognized as food by your body and therefore mimics a fasting state! The ProLon Fasting Mimicking Diet is your secret to fasting – with real and delicious food. Join the health trend of fasting without going hungry!

ProLon is designed to prime your body to transition into a fasting state so it can begin celluar recycling.

ProLon guides your body to switch to a fat burning state. Cellular cleanup begins.

Many people reach a degree of the fat burning metabolic state known as full ketosis.

Autophagy continues and stem cell-based regeneration is ramping up.

Stem cell-based regeneration continues for rejuvenation from within.

The benefits continue after the 5 days end.

Stem cell-based rejuvenation continues for up to 5 days once you complete the ProLon Fasting Mimicking Diet and return to your regular healthy meal plan. See the providers at RMD. We have many options for nutritional support /  programs, fitness and counseling through your wellness journey.  Nutritional services available.
