Keto Zone Diet Review: Everything You Need To Know

Dr. Colbert is the mastermind behind the Keto Zone Diet. He has been practicing as an anti-aging medical doctor for over thirty years. He is also a world-renowned speaker and author. Dr. Colbert has put years of research and study into finding the perfect option for living a successful and healthy lifestyle through diet.

What prompted Dr. Colbert to study the skin and dieting is the fact that he had his own serious skin condition. He was able to overcome that condition by choosing the right foods and eating more healthily, he had healthy skin. For the first time in his life, he felt comfortable in his own skin.

He learned that certain foods made the body healthier and that the body responded differently to different foods. He spent years testing thousands of foods and different ingredients on himself. Then he did the same thing with his patients. This is how he developed the Keto Zone Diet. In addition, he developed an entire line of Keto Zone Diet nutritional products and supplements.

The Keto Zone System is the best system and was developed with all of the knowledge that Dr. Colbert had. It is the most complete and effective system according to him. It will help you to have a total state of nutrition. This is due to the fact that you are not just entering ketosis to burn excess fat, but also because you are focusing on your complete health and ultimate well-being.

The Keto Zone Diet puts you into Ketosis. You will notice that you no longer have cravings and that you are not hungry all the time. At the same time, you get a boost of energy, improvement in mental clarity, steady improvement in sleep, and an overall healthy and well-rested feeling.

What You Need to Know When Choosing the Keto Zone Diet

The Keto Zone Diet is one of the more comprehensive and serious diets on the market today. Keto has some benefits for those who choose this way of life.

Not only do they reach their optimal weight, but they also can maintain weight more easily (long-term weight loss). It can leave you feeling healthier, and more energized, and overall give you the best possible state of health. Plus you are going to sleep better and have an improved mental status.

Features of the Keto Zone Diet

One of the things that you have to remember with keto is that it is more than just a diet. It is a way to live. If you do not consider going keto for life, you might want to reconsider.

No diet is a magical cure, the way to have the best results is to choose a new way of life. If you choose to go on and off of keto there is a good chance that you are going to mess up your metabolism.  This would cause you to have continuous problems with losing weight forever.

What You Can Expect

The first thing that you should expect is to be patient. Sometimes you will be a lucky keto person who can hit ketosis very quickly after starting the diet. However, there is a good chance that you are going to need to be patient and wait. The more weight that you have to lose, the faster that your body is going to get into ketosis (as a general rule of thumb, but not always).

You will be able to customize the keto diet as well. This means that each person’s body is different and how they process carbs is different. Some people are able to have 50 grams of carbs a day and still have success with keeping their bodies in ketosis.

Other people are only able to have 20 grams. Some people might have to eat as little as 4 grams of carbs a day. Learning your body is a process that is going to take time. Don’t worry or stress, just prepare to really learn to focus on your body and how you feel as you are eating.

Weight Loss Benefits of Ketosis

The main goal of the keto diet plan is to put the body into ketosis. In ketosis, the body actually fuels itself by burning fat instead of burning carbohydrates. You are resetting your body to do its job differently.

Fat burning is one of the best benefits of the Keto Zone Diet because you are going to lose weight quickly. Be forewarned though that if your body is used to eating a higher carb way and if it is used to you eating low-fat foods you might see some initial weight gain with the keto diet.

Overall Health Benefits

There are a lot of amazing health benefits with the Keto Zone Diet. These include that you are going to have fewer cravings. You will notice very quickly that you no longer have that desire for sweet treats or bread. Pretty soon, you are not going to like eating those things at all.

Additionally, you are going to be able to lower your caloric intake. This can lead to a number of additional benefits. While keto diets are often high in fat, they are often lower in calories because you are eating healthy fats that come from natural sources which do not contain the higher calories you see in most processed foods do.

Things You Should Know Before Starting with the Keto Zone Diet

Before you get started on the keto diet, you must first remember that you are going to need to make this a lifestyle change. You do not want to use keto like you would a normal diet.

Instead of just going back and forth, you will want to jump in with keto and make this your life. If you are not going to do this, then you need to consider another plan for weight loss. Going back and forth with the keto diet is going to lead to nasty overall gains in weight and will leave you feeling sluggish and bad.

It is never going to be easy to make a lifestyle change. However, with the keto changes, you will want to stay on the plan since you are going to feel so much better. Additionally, you are going to be able to add in some simple Keto-friendly foods that are going to help you stay on track, thanks to the Keto Zone products that are readily available.

A Quick Breakdown,  Foods Allowed and Not Allowed

  • Water — This is the best choice for drinks. It is simple, available everywhere, and remarkably good at purifying your body.
  • Broth — Broth is loaded with tons of vitamins and minerals and is a great alternative when you need a good snack. It is a great way to help replenish electrolytes while offering a boost in energy.
  • Coffee — Coffee can help aid in digestive issues, with weight loss, and can help improve mental focus.

meal in container

We all know the struggle of living a very busy life. One of the hardest things about any diet is trying to find a way to enjoy healthy meals even when you feel like you have no time. When you are on the Keto Zone diet, you will find that eating healthy becomes natural. Thanks to meal prepping you can be sure to always stay on task.

Here are some tips that can help you to prep your Keto Zone meals so that you can save time and still stay on track.

Why You Should Prep Your Meals

There are a number of reasons that you should meal prep, and while I am sharing some here, you can potentially name even more.

  1. Saves you time
  2. Saves you money
  3. No worry over what to eat
  4. Don’t have time; you have something prepped
  5. No excuses to not eat a healthy meal
  6. Stay in ketosis
  7. Have your meals ready to go
  8. Never be without a healthy food choicе
  9. Stay serious about your diet
  10. Avoid temptations that you are unable to handle

Tips For Meal Prepping Success

Tip #1 — Decide the Meals that You Will Have for the Week

One of the things that can help you with success is choosing to prep a series of weekly meals.

Tip #2 — Choose Meals That Are Very Simple

There are a number of very easy meals that you can have when you are eating on the Keto Zone diet. Some of these include breakfasts like keto coffee or a couple of eggs made with avocado and grass-fed butter. The lunches can be a big salad with some keto protein, vegetables that are low-carb and have been steamed with some grass-fed butter or olive oil.

Tip #3 — Prep Extra Food for Leftovers

When you cook a meal, consider doubling up and having leftovers. This will help you always to have something delicious to eat.

Tip #4 — Don’t Forget to Prep Snacks

The Keto Zone diet leaves you with little feelings of hunger or desire to snack. Instead of just grabbing something on the go, if you are a snacker make sure that you prep your snacks for the week too. Single serving sized containers or bags of snacks make them simple to grab no matter where you are going.

Tip #5 — Be Okay with Repetition and Simplicity

When you are doing the Keto Zone diet, you want to make sure that meals are simple. One of the ways that you can mix things up is to try different meals. Be simple in the meals that you try and consider making simple changes that offer you a delicious variety without any struggle. Try to do a few things with each meal. If you plan on many of the same meals you are going to reduce any anxiety over what to eat. Plus, you do not have to think, and you know what to keep on hand so that you can always cook a meal even if you are running late.

Add healthy keto fats to every meal. Women should have two or three tablespoons at each meal while men should have three or four.

Make sure that you have keto-friendly proteins at each meal as well. Women should have three or four ounces, and men should aim for three to six ounces.

Include keto-friendly vegetables at each meal. You can have between two and six cups of salad or between one and two cups of cooked keto vegetables each day. You can spread these out throughout the day at any meal or as snacks.

Tip #6 — Go Shopping One Time Per Week

Make a comprehensive list of all of the meals that you are going to eat. Then go through each meal and list the ingredients. Check pantry item to make sure that you have what you need. Then go shopping once and avoid heading to the store in between. Sticking to a meal plan is much harder if you are spending a lot of time in the grocery stores. Additionally, avoid all of the middle isles in the grocery store. This will really help you to focus on what you should be eating.

Tip #7 — Don’t Forget to Check All Keto Recipes for the Week Before Heading to the Store

Make sure that you are checking each keto recipe and that you have all the needed items. Nothing is more frustrating than coming home from a long day, going to cook a meal, and then finding out that you do not have everything that you need. Take time to check each recipe when making your grocery lists.

A Quick Look at Keto Zone Products

Thankfully Dr. Colbert has introduced a line of products that are Keto Zone Diet friendly and offer you the chance to have some delicious “treat” like foods. Plus, they are convenient things to have as well.

Dr. Colbert’s Keto Zone Diet

The book that started it all – If you want to make sure that you are doing it right, read the book. The book offers great insight into the ketosis process and really gives you practical suggestions that will aid in your ability to change your lifestyle. We have enjoyed the book. Dr. Colbert’s Keto Zone Diet: Burn Fat, Balance Appetite Hormones, and Lose Weight.

The Fat Zyme is a great supplement to take when on the Keto Zone Diet. It is the first digestive enzyme for those who are doing the keto lifestyle. It can help you with a number of intestinal and digestive issues. We were able to notice that we had fewer issues with digestive problems.

This unflavored powder is a great way to boost the protein in your diet. It helps to support your digestive system, skin, joints, hair, and nails. We noticed that our nails and hair grew faster. We also noticed that we had fewer digestive issues and that our skin was clear. Plus, those of us who suffer from achy joints noticed an improvement there.

Iced Krill offers you the chance to get all of the omega-3 fatty acids that you need. It is a great choice to ensure that you have the best brain development among other things. We noticed an improvement in energy and overall mental focus and ability. [

There are two flavors of Keto Zone Instant Ketones, both Coconut Cream and Limeade are available, and both are delicious. They are a great way to boost your fat-burning potential with a delicious daily drink. The only complaint that we had was that this was one supplement that was a little more expensive.

It was $210 for a two-month supply which is not something that is affordable for everyone.

There are three varieties of MCT Oil Powder: Hazelnut, Pumpkin Spice, and Unflavored. MCT Oil helps to trigger the metabolic system to change from burning carbs for energy to burning fat for energy, supporting heart health, and brain health. All three flavors were nice, we chose to use the unflavored in a smoothie, and the other two we just drank.

They seemed to help us stay in ketosis, and we all noticed a great amount of fat loss when using these. We also appreciated the price point since it was a more affordable option.
