The Keto Diet works simply by restricting carbohydrates to 20-30 grams per day which forces the cells to release stored fat. Your liver converts that fat into ketones which you use as energy. You lose weight (fat) and as the body gradually adapts to burning fat, you have less hunger and cravings and health improves.
When people ask me for a quick keto diet explanation I sometimes struggle.
I tend to make it more complicated than it is. The word “keto” is just short for ketogenic and that just means your body is breaking fat down into ketones and you’re using that as energy.
The popularity of the Keto Diet can’t be ignored.
If you check Google Trends for “keto,” the search phrase “Keto Diet Explained” is the 4th most popular trending search phrase. The popularity of keto just exploded in March 2019 and now shows a 900% increase in search traffic
In 2018, the search term, “What is the Ketogenic Diet,” was the 8th most popular search term in the diet category. It was searched for on average 6,600 times per month.

There has been a lot of negative publicity and false myths relating to the Ketogenic diet, but that hasn’t slowed it down. In fact, The Keto Diet is making a serious dent in the diet industry. Weight Watchers is taking a hit. On Wednesday (02/27/19), its stock fell 35% in morning trading.
“Right now, we have a keto surge, it’s a meme, it’s not like a company. People have keto donuts and everybody on the diet side looks for the quick fix. We’ve been through this before and we know we are the program that works.”Mindy Grossman, CEO Weight Watchers
She’s partly right, Keto is not a company that is selling something. It’s just a different way to eat based on modern science.
If I had to give someone an explanation of what the keto diet is I would simply say it’s a modern approach to healthy eating. It’s not a diet per se, but a lifestyle. Keto is not just a meme or a fad. Keto is the antidote to type 2 diabetes and yo-yo dieting.
The Ketogenic diet is based on emerging science that focuses less on overall calorie restriction and more on reducing the master storage hormone (Insulin).
“Insulin actively blocks the breakdown of stored body fat, meaning that as long as insulin is high, it will be very difficult to lose weight—even if you are eating very little.”Dr. Sarah Hallberg, DO, MS
Why all the negative press towards the Keto Diet?
Weight Watchers is not the only corporation scared of the Ketogenic Diet. Keto is a legitimate threat to the profits of multiple, billion-dollar industries. The grain, sugar, weight loss, and pharmaceutical industries are all terrified of Keto.
When explaining keto to people it’s important to stress that keto is the best long term diet because it controls blood sugar and insulin.
Transparency Market Research (TMR) is reporting the global diabetes drugs market is predicted to rise from $43. 1 billion in 2016 to $58.4 billion by the end of 2025. Type 2 diabetes holds a leading share in the overall market due to its higher prevalence.
We know the Ketogenic Diet can reverse type 2 diabetes without any expensive drugs.
In 2017, approximately 11.18 million metric tons of sugar was consumed by the US population. According to a new report from BCC Research, the global market for sugar rose from $77.5 billion in 2012 to $97.2 billion in 2017.
As you can see, if the Ketogenic Diet continues to gain momentum, it could impact billions of dollars of corporate profits. There are a lot of very rich people trying to sabotage the Keto diet.
Our computers are constantly being updated, new models of cars come out every few years and science has vaccinations for most communicable diseases these days. But our dietary guidelines have changed little over the years.
The Dietary Guidelines for Americans has been published jointly every 5 years since 1980 by the Department of Health and Human Services (HHS) and the Department of Agriculture (USDA).
The mission statement of the Department of Agriculture is: “It aims to meet the needs of farmers and ranchers, promote agricultural trade and production.”
Yes, they do mention added sugar now, but they still focus on calories and reducing saturated fat and sodium. There is still no mention of reducing high glycemic carbohydrates that raise insulin.
More importantly, the dietary guidelines still do not warn Americans about how unhealthy simple sugar is. It looks to me like The Department of Agriculture has a conflict of interest.
So how does the Keto Diet work?
It works because it looks at weight-loss different. It’s a low insulin diet and not necessarily a low-calorie diet. It forces your body to use fat as energy. Instead of counting calories on keto, you count your macronutrient intake. You focus on keeping your daily carbohydrate intake to 20-30 grams a day.
The ketogenic diet macronutrient ratio:
- 60-75% of calories from fat
- 15-30% of calories from protein
- 5-10% of calories from carbs
The non keto-friendly food list:
Instead of worrying about what you can put into your mouth, you focus on what you can’t. By cutting out all high glycemic carbohydrates you lower your glucose, which in turn lowers your insulin.
- Sweet potatoes
- Fruit and fruit juice
- Coffee creamers
- Diet sodas
So what can you eat on Keto?
A good explanation of keto has to include the glycemic index (GI).
You want to focus on foods that are low on the glycemic index (GI). The glycemic index assigns a number value to food based on how much ( and the rate) the food raises your blood sugar (glucose). I recommend reading all about the glycemic index here.
Meats, fats don’t have a GI score, so they are acceptable.
Some keto friendly foods to eat:
- Olives and olive oil
- Coconut oil
- Nuts: macadamia, pecans, walnuts
- Kefir and heavy whipping cream
- Leafy green vegetables
- Cucumber and pickles
- Green beans
- Brussels sprouts
- Water, sparkling water, tea
- Keto Coffee (Bulletproof coffee)
- Unsweetened flax milk and macadamia nut milk
- Unflavored whole milk Kefir
- Keto Superfoods

Without carbohydrates for energy and in a low insulin environment, the body readily releases fatty acids into the bloodstream. The liver then converts those fatty acids into ketones. Your body can use those ketones as energy.
Keto explained broken down into 4 phases:
The keto-adaptation phase:
There is a transition period where your body adjusts to using fat as fuel instead of carbohydrates. The adjustment period can last between 3-6 weeks. When the adjustment period ends it gets much easier, it’s what’s known as becoming fat or keto-adapted.
Keto Coffee can help you get fat adapted.
While increasing your fat intake it’s important to understand the difference between good fats and bad fats and not follow the lazy keto diet.
Many people get what is known as Keto-Flu as they are getting keto adapted. It’s not really the flu, it’s just your body fighting the sugar addiction.
For those that stick with it and fight through the fat adaption period, will be rewarded with a lifetime of excellent health and ideal body weight.
Expect to lose 10-15 pounds in the first few weeks. Most will be water weight though so don’t think it will be that easy forever.
The healing phase:
This is the phase where it gets much easier, but also where most people hit a weight loss stall or a keto weight loss plateau.
Insulin resistance has to improve and the liver has to heal and get accustomed to converting fat into ketones. Many people that begin keto have a fatty liver and the liver isn’t efficient yet.
The weight loss phase:
They also call this the whoosh effect. The fat just whooshes out of your fat cells and you really start losing weight. Everyone is different, but it’s usually about 4-8 weeks for this phase to set in.
An explanation of ketosis is in order here.
When you burn fat for energy your liver converts the fat into ketones. Ketone bodies are composed of three compounds (acetone, acetoacetic acid, beta-hydroxybutyric acid).
This study on PubMed hypothesizes, “That increasing the levels of ketone bodies will also extend the lifespan of humans and that calorie restriction extends life span at least in part through increasing the levels of ketone bodies.”
During this phase you will have very few cravings, have plenty of energy and can easily skip meals and “Fast” without any problems.
You can start fasting and eating one meal a day (OMAD) here. You won’t get low blood sugar because of gluconeogenesis. This is where you can also experiment with different techniques like an egg fast.
Gluconeogenesis is the endogenous production of glucose in the body, especially in the liver primarily from lactic acid, glycerol, and the amino acids alanine and glutamine.
The sustainment phase:
The phase is difficult and could take up to a year. You have reached your target weight and have settled into a good, sustainable low carbohydrate eating routine.
It’s difficult because it’s easy to get complacent. You might start introducing some carbohydrates back into your diet like beans and sweet potatoes.
I am in this phase now and check me weight daily. When I see my weight climbing back up I start fasting longer, working out more and eating more keto friendly superfoods.
The Ketogenic Diet makes you a fat burning machine. When you’re using ketones as energy, you have less hunger, optimum health, and improved metabolic flexibility. Ketones are the super fuel that makes the Ketogenic Diet so successful.
So, this is just a basic keto diet explanation, but if you need support reach out and I will be more than happy to help. I recommend you also read the keto diet beginners guide and if you’re ready to start keto, read how to get started on the keto diet.
