Optimal Weight Program

At the Marcus Institute, we provide the thorough and thoughtful care you need to reach your optimal weight, with plans designed specifically for you. In fact, our approach to weight loss is so personalized, you can call it the opposite of “one size fits all.”

Dr. Staid, who is board-certified in Internal and Integrative Medicines and specializes in Nutritional Sciences and Biochemistry, starts by reviewing your medical records going back up to 2 years. This helps her create a timeline of your health, rather than the 20-minute snapshot most appointments provide.

Next, she draws advanced labs to go deep into your biology and underlying imbalance, including:

  • Nutrigenomic DNA testing to assess how your body handles both macro-nutrients and micro-nutrients;
  • Specialized functional nutrient tests to determine your body’s nutrient imbalances and deficiencies; and 
  • Stool testing to evaluate how your body digests and processes food, to uncover any imbalances or inflammation that may be present in your gastrointestinal system, and to evaluate the health of your gut microbiome — a factor that has been found to be critically important in weight management1

Dr. Staid also gathers essential details that are often overlooked: your individual stressors, relationships, work environment, and other lifestyle factors that are central to your well-being and likelihood for success.   

These layers of insight combined give Dr. Staid the clearest picture possible as she identifies and partners with you to eliminate the foods, patterns and obstacles that are holding you back, and embrace effective solutions that are just right for you.


By partnering with the Marcus Institute you’ll walk away with a personalized healthy eating plan that sticks, exercise options you enjoy, and proven techniques to help you reinforce your healthy lifestyle choices. 

Additional recommendations may include micronutrient infusions, stress management sessions and other targeted therapies. You’ll also receive continuing support and follow-up appointments as needed to help you fine-tune your strategy and strengthen your results.
