Ketosis occurs when a lack of carbohydrates forces your body to use up its stored glycogen reserves, and instead your body begins using stored fat as its primary energy source.

To achieve ketosis,  you will need to ELIMINATE all high carb foods from your diet including sugar, bread, pasta, rice, beans and starchy vegetables such as potatoes.   All of these high carb foods convert to glucose (sugar), which will prevent your body from entering ketosis. You’ll also need to cut out most fruits and all sugary drinks such as soda, iced tea, alcohol and replace them with water, flavored seltzer, or coffee/tea.  Refer to the ‘Avoid’ section of mKeto Grocery Shopping Cheat Sheet for additional guidance on Keto Food Do’s and Don’ts.

Foods to Avoid on Keto

Aim for no more than 20-25 grams of Net Carbs (or about 5% of your calories coming from carbs) per day to enter ketosis.   Start reading labels to familiarize yourself with how many Net Carbs are in each food. Not sure how to calculate Net Carbs?  Refer to my How to Calculate Net Carbs post for more guidance.  

You can also download a Carb Tracking app such as CarbManager which is helpful to identify the number of Net Carbs in foods that don’t have nutrition labels on them.



Fat becomes your primary energy source on a ketogenic diet, so it’s critical that you’re consuming an adequate amount.  Consuming a high amount of healthy fats will help boost your ketone levels – which is a sign that you’ve hit ketosis.  Approximately 70% of your calorie intake should come from fats.  Refer to my Easy Keto Meal Planning for Beginners post for examples of how to add fat to your meals.

Monitor your protein intake.  Consuming too much protein may suppress ketone production, while too little protein may lead to muscle mass loss.  You should aim for approximately 20% of your calories to come from protein. Refer to my Easy Keto Meal Planning for Beginner’s post for guidance on incorporating proteins into your meals.

Preferably you should aim for high-quality protein sources such as grass-fed beef, wild-caught fish or free-range eggs – these will supply your body with the most nutrients.

Fasting or Intermittent Fasting will help you get into ketosis faster and aids weight loss, among other health benefits.  Try skipping a meal (such as breakfast) or fasting for an entire day.  If you accidentally (or intentionally) cheat and fall out of ketosis, fasting is the  QUICKEST way to get yourself back on track.


It’s important you maintain a proper level of hydration when you start the Keto diet. Aim to drink at least 8 cups of water a day. Staying hydrated helps regulate vital body functions and controls hunger levels.


Exercise depletes the body’s glycogen reserves which are stored in your liver and muscles.  When glycogen reserves are low, your body automatically reverts to burning fat for energy through ketosis.  Burning fat combined with an active lifestyle will expedite weight loss.


A successful keto diet leads to a reduction in blood sugar levels and an increase in ketones. Testing your ketone levels is the best method to ensure you’ve achieved ketosis.  Refer to my How to Test Your Ketone Levels post for my info.

It typically takes anywhere from 2-4 days to get into ketosis.  If you’re still not in ketosis after several days, you may want to take a closer look at your diet and track your carbs more carefully.  Watch out for hidden carbohydrates and sugars in condiments and prepared foods.


Starting a keto diet may cause electrolyte imbalances if you don’t supplement because your body tends to deplete them quickly on a keto diet.  Supplementing with electrolytes such as sodium and magnesium are vital to replenish lost minerals and reduce the potential for ‘keto flu’ symptoms like fatigue, headaches, brain fog and digestion issues.  

If you’ve hit ketosis but are experiencing Keto Flu symptoms, the FIRST thing you should do is boost your water and electrolyte intakes (including sodium, magnesium, and potassium – ideally through food sources).  Refer to my How to Fight Keto Flu and my Supplementing Electrolytes on Keto posts for more details =) .

I want to emphasize that this is a critical step that often gets overlooked by those new to Keto.  If you want to be successful, it’s essential you  take care of your electrolyte needs.


Last but not least, don’t focus too much on the scale.  While it’s one method people use to assess progress during their Keto journey, it’s certainly not the only way.  Chances are you may see inches coming off your body or clothes starting to fit more loosely even without the scale numbers budging.  That’s why I always recommend you take a ‘Before’ photo so when you hit what seems like a weight loss stall, you can reflect back and visually observe just how much progress you’ve actually made.
