Why Medical Partnership Matters

Many people begin keto independently and experience positive results such as weight loss, improved blood sugar control, reduced hunger, and better metabolic health.

However, keto can also affect:

• Blood sugar levels

• Blood pressure

• Hydration status

• Electrolyte balance

• Kidney function measurements

• Cholesterol and triglycerides

• Medication requirements

Because of these changes, working with healthcare professionals can help you:

• Improve safety

• Monitor progress objectively

• Identify problems early

• Optimize nutrition

• Adjust medications appropriately

• Personalize keto to your specific health needs

Think of your healthcare team as partners who can help you make informed decisions rather than obstacles to your success.

Who Should Be Especially Careful?

Medical supervision is even more important if you have:

• Diabetes (Type 1 or Type 2)

• Prediabetes

• Kidney disease

• Liver disease

• Heart disease

• High blood pressure

• Eating disorder history

• Pregnancy or breastfeeding

• Multiple prescription medications

• Significant obesity

• A history of electrolyte disorders

Some medications may require adjustment shortly after beginning keto.

Never stop or reduce medications without professional guidance.

Your Healthcare Team: Who Can Help?

Primary Care Physician (PCP)

Your primary care physician is often the best starting point.

Potential benefits include:

• Baseline health assessment

• Ordering laboratory testing

• Monitoring long-term progress

• Reviewing medications

• Identifying contraindications

• Coordinating specialty referrals

A PCP can help determine whether keto is appropriate for your individual situation.

Registered Dietitian (RD)

A dietitian can help:

• Design balanced keto meal plans

• Prevent nutrient deficiencies

• Improve food quality

• Address digestive issues

• Adapt keto to allergies and food intolerances

• Create sustainable long-term eating habits

Look for a dietitian familiar with low-carb or ketogenic nutrition.

Endocrinologist

Especially valuable for:

• Type 1 diabetes

• Type 2 diabetes

• Insulin use

• Complex blood sugar management

• Metabolic disorders

Blood sugar often changes rapidly when carbohydrate intake decreases, making specialist oversight important.

Cardiologist

For people with:

• Heart disease

• Significant cholesterol concerns

• Hypertension

• Prior cardiac events

A cardiologist can help evaluate cardiovascular risk factors and monitor relevant markers.

Nephrologist

For individuals with:

• Chronic kidney disease

• Reduced kidney function

• History of kidney-related complications

Protein intake, hydration, blood pressure, and laboratory monitoring may require individualized guidance.

Other Practitioners That May Provide Support

Depending on your interests and health goals, some people also work with:

Functional Medicine Physicians

May focus on:

• Lifestyle interventions

• Nutrition

• Metabolic health

• Comprehensive laboratory testing

Approaches vary significantly among practitioners.

Naturopathic Doctors

Some individuals seek support for:

• Dietary counseling

• Lifestyle changes

• Supplement discussions

Training and scope of practice vary by location.

Health Coaches

Can assist with:

• Accountability

• Habit formation

• Goal setting

• Meal planning systems

Health coaches should complement—not replace—medical care from qualified healthcare professionals.

Baseline Testing Before Starting Keto

Before starting a keto diet, ask your healthcare professional what baseline measurements they suggest. Such tests check for any conditions that would contraindicate a keto diet and also make it easier to evaluate your future progress. Some of the tests your provider make suggest include:

Basic Metabolic Panel (BMP)

Provides information on:

• Glucose

• Sodium

• Potassium

• Kidney-related markers

• Carbon dioxide (bicarbonate)

Useful for hydration and electrolyte monitoring.

Comprehensive Metabolic Panel (CMP)

Includes additional information about:

• Liver function

• Protein levels

• Electrolytes

• Blood glucose

Frequently ordered as a general health assessment.

Hemoglobin A1c (HbA1c)

Shows average blood sugar over approximately 2–3 months. Particularly important for:

• Diabetes

• Prediabetes

• Metabolic syndrome

Fasting Glucose

Provides a snapshot of blood sugar control. Often evaluated alongside HbA1c.

Fasting Insulin

May provide additional insight into:

• Insulin resistance

• Metabolic health

Not always included in routine testing.

Lipid Panel

Typically includes:

• Total cholesterol

• LDL cholesterol

• HDL cholesterol

• Triglycerides

Many people experience significant triglyceride reductions on keto, although individual responses vary.

Complete Blood Count (CBC)

Evaluates:

• Red blood cells

• White blood cells

• Hemoglobin

• Hematocrit

Provides a broad overview of general health.

Thyroid Testing

Depending on symptoms and medical history:

• TSH

• Free T4

• Free T3

May be appropriate to discuss with your provider.

Optional Tests Worth Discussing

These tests may not be necessary for everyone.

hs-CRP

High-sensitivity C-reactive protein is a marker associated with inflammation.

Vitamin D

Many adults have suboptimal vitamin D levels.

Vitamin B12 and Folate

Especially useful if:

• You have absorption concerns

• You follow restrictive eating patterns

• You have symptoms suggestive of deficiency

Iron Studies

May include:

• Ferritin

• Iron

• Transferrin saturation

Particularly important if symptoms suggest deficiency.

Uric Acid

Can be helpful because temporary increases sometimes occur during early keto adaptation.

Suggested Monitoring Schedule

When you consult your healthcare professional before starting a keto diet, ask them what schedule they recommend for ongoing monitoring. Individual needs vary, but many people discuss testing at these intervals:

• Before starting keto

• 6–12 weeks after starting

• Every 6–12 months

More frequent monitoring may be appropriate depending on health conditions.

Medications That May Require Special Attention

Many prescription medications, over-the-counter drugs, and dietary supplements can affect—or be affected by—major dietary changes, making it important to review them with your healthcare team. For example, some may be incompatible with a keto diet or require closer monitoring or adjustments. Changes in diet, body weight, blood sugar, fluid balance, and other factors can also affect how certain medications and supplements work. Examples include (but are not limited to):

Diabetes Medications

Changes in carbohydrate intake can significantly affect blood glucose levels, which may alter medication needs and increase the risk of hypoglycemia if not appropriately managed. Examples include:

• Insulin

• Sulfonylureas (e.g., glipizide, glyburide)

Blood Pressure Medications

Reduced carbohydrate intake may be associated with changes in fluid balance and blood pressure, which can influence medication requirements. Examples include:

• ACE inhibitors (e.g., lisinopril)

• ARBs (e.g., losartan)

• Beta blockers (e.g., metoprolol)

Diuretics

Changes in fluid and electrolyte balance may be relevant when using medications that affect hydration status. Examples include:

• Hydrochlorothiazide

• Furosemide

Cholesterol-Lowering Medications

Dietary changes may influence lipid levels, which can be relevant for ongoing cardiovascular risk management. Examples include:

• Statins (e.g., atorvastatin, simvastatin)

• Ezetimibe

• PCSK9 inhibitors

Thyroid Medications

Changes in body weight and metabolism may influence thyroid hormone requirements in some individuals. Examples include:

• Levothyroxine

Anticoagulants (Blood Thinners)

Dietary patterns and nutrient intake variability may be relevant for monitoring clotting status. Examples include:

• Warfarin

• Direct oral anticoagulants (e.g., apixaban, rivaroxaban)

Mental Health Medications

Changes in appetite, weight, and metabolic state may be relevant for some individuals using psychiatric medications. Examples include:

• SSRIs (e.g., sertraline, fluoxetine)

• SNRIs

• Atypical antipsychotics (e.g., quetiapine, olanzapine)

Seizure Medications

These are historically associated with therapeutic ketogenic diets and may require individualized medical oversight. Examples include:

• Valproate

• Carbamazepine

• Lamotrigine

Over-the-Counter Pain Relievers (NSAIDs)

May be relevant in the context of kidney function, hydration status, and overall medical considerations. Examples include:

• Ibuprofen

• Naproxen

Laxatives

Changes in dietary fiber intake and hydration habits may influence use patterns or tolerance. Examples include:

• Polyethylene glycol (PEG)

• Senna-based products

Electrolyte Supplements

Commonly used in low-carbohydrate dietary patterns and may overlap with medical electrolyte management. Examples include:

• Sodium supplements / electrolyte powders

• Potassium supplements

• Magnesium supplements

Fiber Supplements

May be used depending on dietary composition and individual gastrointestinal response. Examples include:

• Psyllium husk

• Inulin

Fat-Soluble Vitamins

Supplementation practices may vary depending on dietary intake patterns. Examples include:

• Vitamin D

• Vitamin A

• Vitamin E

• Vitamin K

Stimulants and Herbal Supplements

May influence hydration status, heart rate, blood pressure, or sleep in some individuals. or Examples include:

• Caffeine supplements

• Green tea extract

Questions to Ask Your Doctor

Consider discussing the following:

• Is keto appropriate for my health situation?

• Which lab tests should I obtain?

• How often should I be monitored?

• Do any of my medications or supplements require adjustment?

• Will any of my medications of supplements be affected by changes in diet, body weight, blood sugar, fluid balance, and other factors?

• Are there specific nutrients I should monitor?

• What warning signs should I watch for?

• What goals should I track?

• Do you have any other concerns?

What to Track Between Appointments

Maintaining records can improve the usefulness of follow-up visits. Consider tracking:

☐ Weight

☐ Waist circumference

☐ Blood pressure

☐ Fasting glucose

☐ Ketone measurements (if desired)

☐ Energy levels

☐ Hunger levels

☐ Exercise performance

☐ Sleep quality

☐ Medication changes

☐ Laboratory results

Signs You Should Contact Your Healthcare Provider

Seek professional guidance if you experience any of the following while on a keto or low-carb diet:

• Persistent dizziness

• Fainting

• Severe weakness

• Recurrent hypoglycemia

• Significant blood pressure changes

• Ongoing vomiting

• Severe dehydration

• New or worsening symptoms

Do not assume every symptom is simply "keto flu."

Building a Long-Term Partnership

The most successful keto journeys are often supported by:

• Regular monitoring

• Objective testing

• Evidence-based decision making

• Open communication

• Individualized adjustments

Rather than viewing healthcare professionals as separate from your keto journey, consider building a collaborative team that helps you safely pursue your goals while monitoring your overall health.

A well-designed keto diet combined with appropriate medical oversight can provide a more informed, personalized, and sustainable path toward better metabolic health.
