• Refrain from excessive antibiotics and processed foods.

Why This Matters:

Healthy gut is associated with robust immunity, improved mood, enhanced nutrient uptake, and reduced inflammation levels.

No One Diet Fits All:

What helps one person might not help another due to variation in genetics, lifestyle, health conditions, and preferences.

Examples:

• A person with insulin resistance might find the keto diet useful, but someone with thyroid problems would not.

• Intermittent fasting can help improve metabolic health, but is not appropriate for individuals with eating disorders.

Why This Matters:

Custom-tailored nutrition allows one to make informed and sustainable decisions regarding their body’s nutrition through the use of DNA tests, health screenings, and one’s medical history.
