The Ketogenic or Keto diet is a high-fat and low-carb diet. While it may seem counterintuitive to consume more fat to lose weight, with the ketogenic diet, it is not. By reducing your carbohydrate intake, your body begins to burn fat instead of carbs. This state is called ketosis and is what the keto diet strives for.
By tracking your daily macronutrient (carbohydrates, proteins, and fats) consumption and limiting it to 70 percent fat, 20 percent protein, and 10 percent carbohydrates, your body will enter into a state of ketosis after several days to a week.
A Ketogenic diet promotes weight loss and is studied continually for its effects on brain function, heart health, and more. The ketogenic diet is one of the best diet plans.
Read on for everything you need to know before starting your ketogenic diet.
How Does the Keto Diet Work?
The Keto diet works by changing where we get our energy and how our bodies burn energy. Ketogenic eating forces the body into the metabolic state of ketosis. Ketosis is one of the ways the body can produce energy when other food sources are unavailable.
Normally, cells transfer energy to our bodies through blood sugar absorption. Blood sugar is produced through the consumption of carbohydrates.
When the body consumes fewer carbohydrates, it seeks other means to produce the energy that we need. Ketone bodies, or ketones, are produced by the liver and absorb fat to use for energy when carbohydrate levels in the body are low.
By switching from blood sugar energy to the energy produced by ketones, the keto diet enables weight loss and a reduced appetite. If you don’t know what will you eat on a ketogenic diet, you can find a lot of food on the keto diet food list.
What Are the Health Benefits of a Keto diet?
The keto diet has been widely studied for its assistance in reducing seizures in epilepsy patients. As studies continue to emerge, we see that the keto diet has health benefits for weight loss, heart health, improved brain function, reduced acne, and more.
- Weight Loss with Ketogenic Diet
- Improved Heart Health with Ketogenic Diet
- Protected Brain Function with Ketogenic Diet
- Improved PCOS Symptoms with Ketogenic Diet
1. Weight Loss with Ketogenic Diet
Patients experience weight loss with the ketogenic diet through a reduced appetite and a boosted metabolism. There have been many studies on the efficacy of the keto diet for weight loss and assisting patients with obesity.
2. Improved Heart Health with Ketogenic Diet
Ketogenic diets significantly decrease LDL cholesterol and increase HDL cholesterol for improved heart health.
3. Protected Brain Function with Ketogenic Diet
Studies show that the keto diet can be neuroprotective and possibly assist patients with Alzheimer’s and Parkinson’s disease.
Other studies suggest that the ketogenic diet can enhance the effects of radiation treatments on patients with brain tumors.
4. Improved PCOS Symptoms with Ketogenic Diet
Ketogenic diets can help improve symptoms of polycystic ovary syndrome. By decreasing insulin, glucose, and testosterone in women with PCOS, a keto diet can help alleviate symptoms and potentially increase fertility.
What Are the Health Risks of a Keto Diet?
The keto diet has some associated health risks. It can be challenging to achieve nutritional needs with a highly restricted diet. Talk with a nutritionist or doctor about how your body can best reap the benefits of the keto diet without sacrificing your nutrition.
The keto flu is a common symptom of the keto diet. Many people starting out experience the keto flu within two to seven days of strictly reducing their carb intake.
The keto flu does not necessarily mean you are in a state of ketosis, but an indication that your body is adjusting how it metabolizes fats and carbs. Symptoms of the keto flu include fatigue, headache, and brain fog.
Keto diets are not recommended for anyone with liver, pancreas, gallbladder, or thyroid conditions.
How to Do the Keto Diet?
The Standard Keto diet restricts your food intake to 70% fat, 20% protein, and 10% carbohydrates. Generally, this is under 20-50 grams of carbohydrates per day. Each body is unique, and the gram amount is adjusted to each person differently.
The cyclical keto diet is the same as the standard keto diet but allows you a couple of cheat days in between.
When getting started with the keto diet, it can be a math game calculating your daily calorie and macronutrient intake. However, it is important to do the calculations and follow these guidelines to achieve ketosis.
- Start Familiarizing Food Labels
- Plan Your Meals Ahead of Time
- Customize Keto Meals to Your Liking
- Search for Keto Diet Meal Plans
- Look for a Frozen Keto Meal Plan
- Bring Your Own Food
1. Start Familiarizing Food Labels
Get acquainted with the nutritional information on your favorite foods. US food labels list fat and carbohydrates in grams and percentages. Protein is listed in grams only.
Many keto dieters calculate the net amount of carbs they eat rather than the total because dietary fiber is not digested. Dietary fiber and total sugars are listed separately on the label for easy subtraction.
Once you have spent some time eating keto, you will have a general understanding of which food items are your go-to’s and which ones to save for a cheat day.
2. Plan Your Meals Ahead of Time
Meal prep for the keto diet is crucial to success. Measure out foods and do the calculations in advance so that when hunger strikes, you can grab and go without thinking.
3. Customize Keto Meals to Your Liking
Research keto recipes of your favorite dishes to keep mealtime pleasureful. By customizing your keto diet to suit your taste, you are more likely to stick with it longer.
4. Search for Keto Diet Meal Plans
If the calculations and meal preparation are holding you back from starting a keto diet, then search for a keto meal plan in your area. Many places offer deliverable boxes with keto snacks and prepared meals right to your door. This option saves you time and forethought but is more expensive than doing it yourself.
5. Look for a Frozen Keto Meal Plan
If you are short on time, consider a frozen keto meal plan in your region. Like fresh keto boxes, frozen keto meal plans are delivered straight to your door. Simply unpack it into your freezer and conveniently stick to your keto diet.
6. Bring Your Own Food
Going out for dinner can be the bane of a keto dieter’s existence. Most restaurants do not cater to the keto diet without the kitchen making modifications or bringing each ingredient separately. Avoid the temptation to cheat by packing keto-friendly snacks and meals.
How to Start a Keto Diet?
To start a keto diet, you need to track your macronutrients daily. Replace high-carb foods like fruits, grains, sugar, and starchy vegetables with healthy protein and fat-rich sources.
Allow yourself to reduce your carb intake slowly until you are comfortable eating fully keto. You can monitor your progress into the state of ketosis by checking ketone levels in urine, blood, or breath.
Eating the right amount of keto-friendly foods each day will help you see the keto diet’s weight loss benefits. Avoid making mistakes during keto dieting by drinking lots of water, eating foods rich in Omega-3 fatty acids, and consulting with a healthcare professional.
