I have helped hundreds of women get into ketosis and use th keto diet to get health, happier, and lose weight. This is how I teach my clients to get into ketosis, and avoid the keto flu, mostly.

If you’ve heard of the keto diet, you know it’s more than just a trend—it’s a powerful way to burn fat, balance hormones, and boost energy. But how do you actually get your body into ketosis, where you’re burning fat for fuel instead of carbs? For women, this process can feel a little more complex due to hormonal factors, but with the right approach, you can achieve ketosis and experience the benefits of the keto lifestyle.


Whether you’re new to keto or looking to optimize your journey, this step-by-step guide will show you how to get into ketosis in a way that works for your body.

When do you start?

As a woman, this question is not the same as men, your body has a cycle that changes through out the month, and there are times where it is much happier to start ketosis, and times where it will be much more difficult.


The time that your body will be happiest to slip into ketosis for most women is days 3-10 of your cylce. Or directly after you ovulate, if you know that information.


The time you should never ask your body to switch to ketosis, is the 7 days befoe your period. Your body will e looking for carbs naturally at this time, so cravings will hit double hard, and so will PMS.


If you are excited to get started then what I would do is start lowering your carbs and prepping for day one following the guide below.

Tools for Success

Things that really help my clients in the first week or months of their keto lifestyle and things I always have on hand in my house include electrolytes and ketone strips.


Electrolytes will replace the ones that you lose as your body drops excess water weight in the first two weeks, being in keto also uses more electrolytes then the standard american diet so you will always want them on hand. There is a graphic below with the signs to watch for so you know when to take them. I love this brand because of all the ones I have seen, they have the most beneficial ingredients, in ratios that just make sense. Also a ton of flavours and more affordable then many other brands. Check out key nutrients here.


Keto test strips can also be fun and will tell you when your body is starting to make ketones. The goal is not to have it as dark as possible, if it is dark that is fine, you just want to see that your body is making them. Store the strips in a closed container in a dark place, open containers and to much light will make them non effective fast. I like these onees by TruePlus.


Tracking can be very helpful as you learn what foods will fit into a keto lifestyle. My favorite app for tracking macros is Cronometer, it has the most accurate tracker I have found, and most foods you can buy at the store are already in the app. It can be used for free. I highly recommend. They also have a cool womens nutrition tracker in their paid plan which is pretty cool!


The last thing that can be really helpful is having a plan for what you are going eat, the recipes you want to make that you are excited to try. This can help keep you on track. I have a great meal plan that comes out each week with fresh recipes that are delicious that are designed to help you use keto to become a healthier, happier you. You can check that out here.

Step 1: Cut the Carbs

The first and most essential step to getting into ketosis is cutting your carbohydrate intake. Your goal is to switch your body’s fuel source from glucose (sugar) to fat. To do this, you’ll need to reduce your daily carbs to around 20-40 grams.


For women, it’s important to focus on quality carbs. That means swapping out processed foods and sugars for vegetables, leafy greens, and low-carb fruits like berries. These carbs are full of fiber, which helps support digestion and hormone balance.


  • Foods to avoid: Bread, pasta, rice, sugary snacks, soda, most fruits, and starchy vegetables like potatoes.
  • Foods to eat: Meats, seafood, butter, hard cheeses, leafy greens, (romaine, arugula), cruciferous veggies (broccoli, cauliflower), avocados, nuts, and seeds.

Step 2: Increase Your Healthy Fats

Once you’ve lowered your carbs, it’s time to ramp up your healthy fat intake. Fat will become your primary energy source in ketosis, so it’s essential to focus on getting enough of it throughout the day.


Aim to get 70-75% of your daily calories from fat, choosing high-quality fats that nourish your body. Healthy fats help keep you satisfied, balance hormones, and give you steady energy throughout the day.


  • Healthy fats to include: Avocados, olive oil, coconut oil, grass-fed butter, ghee, fatty fish (like salmon), nuts, seeds, and full-fat dairy (if tolerated).
  • Fats to avoid include: Canola, oil, margarine, vegetable oils, soybean oil, and anything hydrogentated.

Step 3: Moderate Your Protein


While protein is important for maintaining muscle and keeping you full, too much can actually interfere with ketosis. If you eat too much protein, your body may convert it into glucose through a process called gluconeogenesis, which can kick you out of ketosis.


Aim to get about 20-25% of your daily calories ( 100 - 150 grams ) from protein. Women should focus on clean proteins that support muscle maintenance without spiking blood sugar.


  • Good protein sources: Meat, fish, poultry, seafood, and eggs. It doesn't have to be grass fed or organic, it can be conventional meat from the grocery store. Whatever works in your budget as long as it gets you the protein you need.

Step 3: Moderate Your Protein



One thing many women don’t realize when starting keto is how important hydration is. As your body burns through glycogen stores (stored carbs), it releases water, which can lead to dehydration and a loss of electrolytes like sodium, potassium, and magnesium.

To avoid the dreaded “keto flu”—a set of symptoms like headaches, fatigue, and irritability—you need to drink plenty of water and replenish your electrolytes.

  • Drink plenty of water: Aim for at least 8-10 cups of water a day.
  • Add electrolytes: Use an electrolyte supplement or consume foods rich in sodium (Himalayan salt), potassium (avocados, spinach), and magnesium (pumpkin seeds, almonds).




Step 4: Stay Hydrated and Replenish Electrolytes

One thing many women don’t realize when starting keto is how important hydration is. As your body burns through glycogen stores (stored carbs), it releases water, which can lead to dehydration and a loss of electrolytes like sodium, potassium, and magnesium.

  • Read this blog all about avoiding the keto flu.





Step 5: Get Moving (But Don’t Overdo It)

Exercise can help speed up the process of getting into ketosis by depleting your glycogen stores. However, it’s important to balance exercise with adequate recovery, especially for women.


High-intensity exercise can elevate cortisol (the stress hormone), which may interfere with your ability to get into ketosis. Instead, focus on moderate exercise that supports fat burning and hormonal balance.


  • Ideal activities: Walking, yoga, Pilates, and strength training.
  • Avoid overdoing: If you’re feeling fatigued or under-recovered, listen to your body and scale back your workouts.
  • Skip workouts entirely on days 3 and 4, opt for a walk if you feel up to it.




Step 6: Monitor Your Ketone Levels

Step 7: Monitor Your Ketone Levels

To know for sure if you’re in ketosis, it can be helpful to measure your ketone levels. There are several ways to do this:


  • Urine test strips: These are inexpensive and easy to use, but they’re less accurate over time.
  • Blood ketone meters: These are the most accurate way to measure ketones but can be a bit more expensive.
  • Breath ketone analyzers: These are also accurate and reusable, measuring acetone levels in your breath.


By tracking your ketone levels, you’ll know when your body has fully transitioned into ketosis and can make adjustments if needed.




Step 7: Be Patient and Stay Consistent


Getting into ketosis doesn’t happen overnight. For some women, it may take a few days; for others, it can take a week or two. The most important thing is to be patient and stay consistent with your food choices, hydration, and lifestyle changes.


As you adapt to the keto diet, you’ll likely experience a range of benefits, from increased energy and mental clarity to weight loss and hormonal balance. But like any lifestyle change, results take time, and it’s important to focus on progress, not perfection.
