This keto meal plan for beginners is a free 5-day starter plan built around simple, real-food meals that keep you under about 25g net carbs a day, the level most people need to reach ketosis.1 No gimmicks, no fancy ingredients, and no stress.
If you're new to keto, this 5-day plan will help you get started without the overwhelm. It focuses on meals you can actually cook (or prep in 15 minutes or less). I designed this specifically for people who feel buried by more complex meal plans.
This plan is part of our full keto meal plans collection. Need a refresher on how keto works first? See our What Is the Keto Diet? guide.

Tips for Your First Week on Keto
Drink more water. When you cut carbs, lower insulin signals your kidneys to release more sodium and water, so you'll lose fluids quickly early on. Stay well hydrated.3
Add salt to your food. You'll excrete more sodium as insulin drops, which is normal and a common cause of early fatigue and headaches.3
Don't skip meals early on. You need steady energy while your body adjusts to burning fat instead of carbs.
Expect "keto flu." You might feel off (fatigue, headache, or irritability) as your body adapts. For most people it lasts a few days to about a week and resolves within two to four weeks.2
Avoid cheat days. A high-carb day usually pushes you over your carb limit and out of ketosis the same day, and it can take several days to about a week to get back in.4

Beginner Keto Questions (FAQ)
How many carbs should a beginner eat on keto?
Most beginners aim for under 20-25g of net carbs per day to reach and stay in ketosis. Authoritative sources put the typical keto range at 20-50g of total carbs daily, so staying under 25g net carbs is a safe, reliable starting target.1
How long does the keto flu last for beginners?
The keto flu usually lasts a few days to about a week, with symptoms like fatigue, headache, and irritability typically peaking in the first week. Most people feel back to normal within two to four weeks.2
Why do I need to add salt when starting keto?
When you cut carbs, insulin levels fall, which signals your kidneys to excrete more sodium and water. That early sodium loss is a common cause of keto flu, so adding salt to your food and staying hydrated helps you feel better faster.3
Will a cheat day kick me out of ketosis?
Yes. A high-carb cheat day usually pushes you over your carb limit and out of ketosis the same day. It can then take several days to about a week to get back in, so it's best to avoid cheat days early on.4
How much does this 5-day keto meal plan cost?
This beginner plan uses everyday grocery-store foods like eggs, chicken, ground beef, leafy greens, and healthy fats. The estimated grocery cost is about $45-60 for the week, with roughly 3-4 hours of total prep time.

The ketogenic diet typically restricts carbohydrates to roughly 20-50g per day to induce ketosis. See Harvard T.H. Chan School of Public Health, Diet Review: Ketogenic Diet for Weight Loss (notes <50g/day, as low as 20g) and Cleveland Clinic, Ketosis ("under 50 grams of carbohydrates per day"). Staying under ~25g net carbs keeps beginners comfortably within this range. ↩︎ ↩︎ ↩︎ ↩︎
"Keto flu" symptoms (fatigue, headache, nausea, irritability) usually appear within the first few days and typically last one to two weeks. See Cleveland Clinic, Keto Flu: What It Is, Symptoms and Remedies (symptoms "typically occur for one to two weeks") and Harvard Health, What is keto flu? (energy usually returns "at the end of a week"). A scoping review of consumer reports found symptoms peak in the first week and largely resolve within about two to four weeks: Bostock et al., Consumer Reports of "Keto Flu" Associated With the Ketogenic Diet, Frontiers in Nutrition (2020). ↩︎ ↩︎ ↩︎
When carbohydrate intake drops, insulin falls and the kidneys excrete more sodium and water, which can cause early fatigue and headaches; replacing sodium and staying hydrated helps. Insulin has a well-documented antinatriuretic (sodium-retaining) effect, so lower insulin promotes sodium and fluid loss. See DeFronzo, The effect of insulin on renal sodium metabolism: a review with clinical implications, Diabetologia (1981), and Harvard T.H. Chan School of Public Health, Diet Review: Ketogenic Diet. ↩︎ ↩︎ ↩︎
A high-carb cheat day generally exceeds your daily carb limit (eating more than ~50g of carbs can end ketosis) and re-entering ketosis can take several days to about a week. See Healthline, Cheating on Keto: Effects and Recovery ("several days to 1 week"). ↩︎ ↩︎
