If you’re starting the keto diet, congratulations! You’re on the path to changing the way your body uses energy—and you might even start to feel it in just your first week. However, you may also feel some side effects that are less than pleasant (hello, keto flu). Don’t worry, though; it’s all part of the process! In this guide, we’ll walk through what to expect in your first week of keto, from the ups and downs to the tips and tricks to help you push through successfully. Ready to dive in? Let’s get started!

What is the Keto Diet?
The keto diet, short for ketogenic diet, is a low-carb, high-fat eating plan designed to get your body into a state called ketosis. Normally, your body uses carbs for energy, but when you’re on keto, you drastically reduce your carb intake and load up on fats. The idea is to switch your body from burning glucose (sugar) for energy to burning fat.
When your body doesn’t have enough carbs to burn, it turns to fat for fuel. This process produces ketones, which your body then uses for energy. Over time, this can help with weight loss, better mental clarity, and even more stable blood sugar levels.
Common Symptoms During the First Week of Keto
Ah, the infamous keto flu. Yes, it’s real, and for most people, it kicks in during the first week of keto. You might experience things like:
- Fatigue: You may feel sluggish and low-energy as your body adjusts to burning fat instead of carbs.
- Headaches: These can be a result of dehydration or electrolyte imbalance.
- Nausea: Some people report feeling a bit queasy, especially in the first few days.
This happens because your body is going through carbohydrate withdrawal and learning how to use fat as a new fuel source. It’s similar to when someone cuts out sugar or caffeine—it takes a few days for the body to catch up. The good news? The symptoms usually only last a few days to a week.
How to Alleviate Keto Flu Symptoms
- Stay hydrated: Drink plenty of water, as your body will lose more fluids than usual.
- Increase electrolytes: Make sure you’re getting enough sodium, potassium, and magnesium. This helps with headaches and fatigue. Adding a pinch of salt to your water can actually help!
- Don’t restrict calories too much: Your body is already adjusting to low carbs, so make sure you’re eating enough food to fuel yourself through the transition.
Signs You’re Entering Ketosis
So, how do you know when your body is switching into ketosis? Here are a few signs:
- Bad breath: Sorry, but it’s true. One of the most common signs is a metallic or fruity taste in your mouth, a side effect of ketone production.
- Increased thirst: You’ll notice you’re thirstier than usual. This is due to the loss of water weight, which we’ll talk about next.
- Reduced hunger: As your body adapts, you’ll find that your appetite naturally decreases.
Want to be sure you’re in ketosis? You can use ketone testing strips (available at most drugstores) or a blood ketone meter to test your ketone levels.
Benefits You May Start Noticing in the First Week
Though the first week can be rough, many people also start seeing some positive changes early on. Here’s what you can look forward to:
- Initial weight loss: Most people notice a significant drop in weight during the first week. This isn’t because you’re shedding fat just yet—it’s water weight. Reducing carbs causes your body to release glycogen (which holds onto water), so you’ll drop a few pounds of water weight.
- Stabilized blood sugar levels: With fewer carbs in your system, your blood sugar becomes more stable. This can help reduce energy crashes.
- Mental clarity (eventually): Some people feel a bit foggy during the transition, but once you’re fully in ketosis, you might notice a boost in mental clarity and focus.
Tips for Surviving Your First Week on Keto
The first week of keto can feel like a rollercoaster, but there are ways to make it smoother. Here’s what you can do:
- Plan your meals ahead of time: Prepping your meals will make it easier to avoid carb-heavy temptations. Stick to simple, keto-friendly foods like avocados, eggs, cheese, and fatty meats.
- Stay hydrated and maintain your electrolytes: This can’t be emphasized enough! Drink water constantly, and don’t be afraid to add a little extra salt to your meals.
- Sample 7-day meal plan for beginners: Start with easy meals like bacon and eggs for breakfast, salads with olive oil and grilled chicken for lunch, and a steak or salmon with veggies for dinner. Keep it simple!
- Avoid the social pressure: Social events can be tricky, especially in your first week. If you know you’re going out, check the menu ahead of time or pack your own snacks to stay on track.
- Manage cravings: Cravings will come, but staying prepared with keto-friendly snacks (like cheese, nuts, or pork rinds) can help you resist temptation.
Conclusion:
The first week of keto might be tough, but it’s also incredibly rewarding once you start to feel the benefits. Remember, the keto flu will pass, and the initial weight loss, mental clarity, and improved energy will kick in soon enough. Stay hydrated, keep your electrolytes balanced, and trust the process. You’ve got this!
Now that you’ve survived the first week, the real fun begins as your body continues to adapt and thrive on keto. Ready for week two? Keep pushing forward, and you’ll be well on your way to achieving your goals!
