Before day one
Write down what you hope to learn. Discuss suitability and baseline checks with your clinician. Plan a few meals, shop within your budget, and decide what to record: hunger, digestion, energy, and how practical meals feel.
Week one: keep meals manageable
Carnivore diet week one does not need an elaborate menu. Cook enough for leftovers and eat regular meals. Some people report fatigue, headaches, or digestive changes during a large dietary change. Do not assume symptoms mean the diet is working.
Week two: review how you feel
Look at your notes. If digestion or energy is getting worse, seek advice instead of tightening the rules. A gradual transition may be easier to manage; a difficult week need not become a test of willpower.
Week three: check the routine
Try another fish or cut if you want variety. Review cost, social meals, and whether you can eat enough. Avoid adding fasting or aggressive calorie restriction to an already large change.
Week four: make a decision
Review your notes with your clinician or dietitian. Decide whether to continue, broaden your menu, or stop. Feeling better does not replace appropriate monitoring, and a month cannot settle long-term safety questions.
Water and electrolytes
Drink regularly. Do not copy a high-salt or potassium-supplement routine from a forum. Kidney conditions and some medications make electrolyte advice especially individual. Ask your clinician what is appropriate for you.
When to stop
Stop and seek medical help for persistent vomiting, severe weakness, fainting, palpitations, or signs of dehydration. Chest pain, confusion, or trouble breathing needs urgent care. Do not change insulin or other medication on your own. MedlinePlus: dehydration.
