Education, not medical care
The coaches, this website and everything they provide (including meal suggestions, macro targets, training programs and answers to questions) are for general educational purposes only. They are not a substitute for professional medical advice, diagnosis or treatment. Using the Service does not create a doctor-patient, dietitian-client or other healthcare relationship.
Hal MacKenzie is a certified health coach and personal trainer, not a physician or registered dietitian. His certifications: Primal Health Institute Health and Nutrition Coach, National Academy of Sports Medicine (NASM) Certified Personal Trainer, and Clean Health Institute Pre Natal Health Coach.
Talk to your doctor first
Consult a qualified healthcare professional before changing your diet, exercise, supplements or medications, and especially if you:
- Are pregnant, trying to become pregnant, postpartum or breastfeeding.
- Have a medical condition, such as heart disease, diabetes, high blood pressure, kidney or liver disease, or a past injury.
- Take prescription medication.
- Have, or have had, an eating disorder.
- Are new to exercise or returning after a long break.
Stop exercising and seek medical help if you feel chest pain, faintness, dizziness or unusual shortness of breath.
Supplements, peptides and lab work
Any discussion of supplements or peptides is educational only. Supplements and peptides are not evaluated by the FDA for safety or effectiveness the way medications are, and some are not approved for human use. They can interact with medications and health conditions. Talk to your doctor before taking any of them.
Any discussion of lab results is for general education and does not replace interpretation by your doctor. The coaches do not diagnose or treat any condition.
AI can be wrong
The coaches' answers are generated by artificial intelligence. They are trained on Hal's coaching methods, but individual answers are not reviewed by Hal and can be inaccurate or incomplete. Never ignore professional medical advice, or delay seeking it, because of something a coach said.
Results vary
Results depend on many factors, including your starting point, consistency, health and genetics. We do not guarantee any particular outcome.
Emergencies
The Service is not for emergencies. If you think you may have a medical emergency, call 911 or your local emergency number right away.
Your responsibility
You are responsible for your own health decisions. By using the Service, you accept the risks of changing your diet, exercise or supplements, and you agree that Health Coaching with Hal is not liable for any injury or health problem that results.
