The weight loss product Jen Keto is likely referring to the ketogenic diet, a low-carbohydrate, fat-rich eating plan that has been used for centuries to treat specific medical conditions. The diet typically involves consuming less than 50 grams of carbohydrates per day and deriving 70-80% of daily calories from fat. The premise of the ketogenic diet for weight loss is that depriving the body of glucose, the main source of energy, will lead to the production of ketones from stored fat. This state of ketosis can lead to weight loss and improvements in health parameters such as insulin resistance, high blood pressure, and elevated cholesterol. However, there are potential side effects and challenges associated with the diet, including hunger, fatigue, and irritability. It is recommended to consult with a physician and dietitian before starting a ketogenic diet to ensure it is safe and tailored to individual needs.
What You'll Learn
The basics of keto
The ketogenic diet, or keto, is a high-fat, moderate-protein, low-carbohydrate diet that has gained a lot of attention as a weight loss method in recent years. The keto diet is not just a trendy diet, it has been around for a while. It first surfaced in the 1920s to help with conditions like epilepsy and diabetes.
The keto diet involves consuming a very low amount of carbohydrates and replacing them with fat to help your body burn fat for energy. The goal is to swap out the glucose calories with fat. In a typical keto diet, your nutrition centres on fatty foods. They'll make up anywhere from 60% to 80% of your daily calories. Proteins make up 15% to 20%. Carbs are restricted to no more than 50 grams. This makes it quite a restrictive diet.
The most important component of the keto diet is a natural process called ketosis. Normally, bodies run very well on glucose. Glucose is produced when the body breaks down carbohydrates. It's a very simple process, which is why it's the body's preferred way to produce energy. When you cut back on carbs or just haven't eaten in a while, your body looks for other energy sources to fill the void. Fat is typically that source. When your blood sugar drops because you're not feeding your body carbs, fat is released from your cells and floods the liver. The liver turns the fat into ketone bodies, which your body uses as its second choice for energy.
When your body burns body fat for fuel, it produces ketones, substances made in your liver. Your body enters a metabolic state called "ketosis". If you follow the keto diet strictly, your body will reach ketosis in about 4 days. You will likely even see several pounds of weight loss the first week.
There are several forms of the ketogenic diet. The classic ketogenic diet is super high in fat (about 80% to 90% of your daily calories), super low in carbohydrates (up to 4% of your calories) and moderate in protein (typically 6-8% of your calories). The standard ketogenic diet (SKD) is the standard diet an individual new to the keto diet would follow. This diet follows keto rules including low-carb, moderate protein and high-fat intake. It typically contains 70% fat, 20% protein, and only 10% carbs in your daily diet.
The cyclical ketogenic diet (CKD) involves periods of higher-carb "refeeds", such as 5 ketogenic days followed by 2 high-carb days. The targeted ketogenic diet (TKD) allows you to add carbs around intense workouts. The high-protein ketogenic diet (HPKD) is similar to the SKD, but you can eat more protein. The ratio is usually 60% fat, 35% protein, and 5% carbs.
What to eat on keto
A typical keto diet plan consists largely of low-carb green vegetables. This short list leaves out carb-heavy foods, such as grains, rice, beans, potatoes, sweets, milk, cereals, fruits and even some vegetables.
Some keto-friendly foods are:
- Full-fat dairy products
- Non-starchy and fibrous vegetables

The benefits of a ketogenic diet
The ketogenic diet has been around since the 1920s and is a low-carb, high-fat diet. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where it becomes incredibly efficient at burning fat for energy.
There are several types of ketogenic diets, including the Standard Ketogenic Diet, the Cyclical Ketogenic Diet, the Targeted Ketogenic Diet, and the High Protein Ketogenic Diet. The Cyclical and Targeted Ketogenic Diets are more advanced methods primarily used by bodybuilders or athletes.
Weight Loss
The ketogenic diet is an effective way to lose weight and lower the risk of certain diseases. Research shows that the ketogenic diet may be as effective for weight loss as a low-fat diet. A review of 13 studies found that following a very low-carb, ketogenic diet was slightly more effective for long-term weight loss than a low-fat diet. People who followed the keto diet lost an average of 2 pounds more than the group that followed a low-fat diet.
Lower Risk of Certain Diseases
The ketogenic diet can help improve risk factors for heart disease, including body fat, HDL ("good") cholesterol levels, blood pressure, and blood sugar. It is also being explored as a potential additional treatment for cancer, as it may help slow tumor growth.
Improved Brain Function
The ketogenic diet may help reduce symptoms of Alzheimer's disease and slow its progression. It has also been shown to cause significant reductions in seizures in epileptic children.
Other Benefits
The ketogenic diet can also help improve symptoms of polycystic ovary syndrome (PCOS) by helping to reduce insulin levels. It may also improve outcomes for traumatic brain injuries and Parkinson's disease, although more research is needed in these areas.
Considerations
While the ketogenic diet has many potential benefits, it may not be suitable for everyone. It can be challenging to stick to due to stringent food restrictions, and it may lead to vitamin and mineral deficiencies if not carefully planned. It is also important to consult a doctor before starting the ketogenic diet, especially for those with diabetes, kidney disease, or other health conditions.
