Quick answer: Common keto questions cover what to eat, how many carbs to allow, side effects like keto flu, alcohol, dairy, cholesterol and long-term safety. In short: focus on healthy fats, low-carb vegetables and quality protein, keep net carbs low, hydrate and replace electrolytes, and work with your provider if you have health conditions or take medication.
Food and macros
What can I eat?
Healthy fats, low-carb vegetables and quality protein. See the keto food list.
Can I still eat carbs?
Yes, from vegetables, nuts and berries, kept low. See net carbs.
Do I need to track macros?
It helps at first. See tracking your macros.
Can I eat dairy?
Yes, full-fat options like cheese, butter and Greek yogurt if tolerated.
Side effects and safety
What are common side effects?
Headache, fatigue and nausea early on. See keto flu.
What about cholesterol?
Keto may raise HDL and lower triglycerides, but LDL rises in some people. Check a lipid panel before and during.
Is keto safe long term?
Long-term safety isn’t fully known. Meet nutrient needs and check in with your provider.
Lifestyle
Can I drink alcohol?
Alcohol slows ketone production and lowers inhibitions. If you drink, keep it occasional and choose dry options.
Can vegetarians do keto?
Yes, with eggs, dairy, tofu, nuts and seeds.
Can I build muscle?
Yes, with enough protein and strength training.
What about eating out?
Grilled meat or fish, salads with oil-based dressing and vegetable sides.
Healthy aging lens
Keto is one tool; the habits that support healthy aging are the ones you can keep.
When to see a naturopathic doctor
- You have diabetes or take insulin, sulfonylureas or SGLT2 inhibitors (risk of low blood sugar or ketoacidosis)
- You take blood pressure medication or diuretics
- You have kidney, liver, gallbladder or pancreas disease, or high cholesterol
- You are pregnant, breastfeeding, or have a history of disordered eating
- You want a keto plan tailored to your labs and goals
See a medical provider promptly for nausea and vomiting, abdominal pain, confusion, fruity-smelling breath with rapid breathing, or very high blood sugar or ketone readings, which can signal ketoacidosis.
