Keto can also enhance metabolic flexibility by promoting the use of fat for energy. | Intermittent fasting may lead to muscle loss, while keto may cause muscle cramps and weakness. |
| 4 | Autophagy Activation | Intermittent fasting can activate autophagy, a process where the body breaks down and recycles damaged cells. Keto can also activate autophagy by reducing insulin levels. | Intermittent fasting may lead to dehydration, while keto may cause constipation. |
| 5 | Brain Function | Both intermittent fasting and keto can boost brain function. Intermittent fasting can improve cognitive function and protect against neurodegenerative diseases. Keto can enhance brain function by increasing the production of ketones, which can provide an alternative energy source for the brain. | Intermittent fasting may lead to fatigue and irritability, while keto may cause brain fog and mood swings. |
| 6 | Cardiovascular Health | Both intermittent fasting and keto can improve cardiovascular health. Intermittent fasting can reduce blood pressure and improve cholesterol levels. Keto can also improve cholesterol levels and reduce inflammation. | Intermittent fasting may lead to heartburn and acid reflux, while keto may cause an increase in LDL cholesterol levels. |
| 7 | Blood Sugar Regulation | Both intermittent fasting and keto can regulate blood sugar levels. Intermittent fasting can reduce insulin resistance and improve glucose tolerance. Keto can also improve glucose tolerance and reduce blood glucose levels. | Intermittent fasting may lead to hypoglycemia, while keto may cause hyperglycemia. |
| 8 | Inflammation Reduction | Both intermittent fasting and keto can reduce inflammation in the body. Intermittent fasting can reduce oxidative stress and inflammation markers. Keto can also reduce inflammation by decreasing the production of inflammatory cytokines. | Intermittent fasting may lead to headaches and dizziness, while keto may cause nausea and bad breath. |
| 9 | Muscle Preservation | Both intermittent fasting and keto can preserve muscle mass. Intermittent fasting can stimulate muscle protein synthesis, while keto can preserve muscle mass by promoting the use of fat for energy. | Intermittent fasting may lead to muscle weakness, while keto may cause muscle cramps and soreness. |
Overall, both intermittent fasting and keto have potential benefits for weight loss, insulin sensitivity, metabolic flexibility, autophagy activation, brain function, cardiovascular health, blood sugar regulation, inflammation reduction, and muscle preservation. However, there are also potential risk factors associated with each approach, such as overeating during the eating window with intermittent fasting or nutrient deficiencies with keto. It is important to consult with a healthcare professional before starting any new diet or lifestyle change.

How does Blood Sugar Regulation differ between Intermittent Fasting and Keto?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Intermittent Fasting | During fasting, the body’s insulin levels decrease, which leads to a decrease in blood glucose levels. | Fasting for too long can lead to hypoglycemia, which can cause dizziness, weakness, and confusion. |
| 2 | Keto | On a keto diet, the body enters a state of ketosis, where it burns ketones for energy instead of glucose. | If the body does not enter ketosis, blood glucose levels can drop too low, leading to hypoglycemia. |
| 3 | Blood Sugar Regulation | Intermittent fasting and keto both lead to a decrease in blood glucose levels, but through different mechanisms. | If blood glucose levels drop too low, it can lead to hypoglycemia, which can be dangerous. |
| 4 | Insulin | Insulin is a hormone that regulates blood glucose levels by signaling cells to absorb glucose from the bloodstream. | Too much insulin can lead to insulin resistance, which can cause high blood glucose levels and type 2 diabetes. |
| 5 | Glycogen | Glycogen is a stored form of glucose in the liver and muscles. | If glycogen stores are depleted, the body will start breaking down muscle tissue for energy. |
| 6 | Ketones | Ketones are produced by the liver when the body is in a state of ketosis. | High levels of ketones can lead to ketoacidosis, which can be life-threatening. |
| 7 | Fasting | Fasting can improve insulin sensitivity and lower blood glucose levels. | Fasting for too long can lead to muscle loss and a decrease in metabolism. |
| 8 | Metabolism | Metabolism is the process by which the body converts food into energy. | A slow metabolism can make it difficult to lose weight and maintain weight loss. |
| 9 | Carbohydrates | Carbohydrates are a type of macronutrient that the body breaks down into glucose for energy. | Consuming too many carbohydrates can lead to high blood glucose levels and insulin resistance. |
| 10 | Fat burning | On a keto diet, the body burns fat for energy instead of glucose. | If the body does not enter ketosis, it will not burn fat for energy. |
| 11 | Energy levels | Both intermittent fasting and keto can lead to increased energy levels. | If the body does not enter ketosis, energy levels may decrease. |
| 12 | Hunger hormones | Intermittent fasting can lead to a decrease in hunger hormones, which can reduce appetite. | If hunger hormones are suppressed for too long, it can lead to overeating and weight gain. |
| 13 | Blood glucose levels | Both intermittent fasting and keto can lead to a decrease in blood glucose levels. | If blood glucose levels drop too low, it can lead to hypoglycemia, which can be dangerous. |
| 14 | Nutrient absorption | On a keto diet, the body may have difficulty absorbing certain nutrients, such as fiber. | A lack of nutrient absorption can lead to nutrient deficiencies and other health problems. |
| 15 | Glucagon | Glucagon is a hormone that raises blood glucose levels by signaling the liver to release stored glucose. | Too much glucagon can lead to high blood glucose levels and insulin resistance. |
| 16 | Liver function | The liver plays a key role in regulating blood glucose levels by storing and releasing glucose as needed. | A damaged liver can lead to problems with blood glucose regulation. |
| 17 | Dietary restrictions | Both intermittent fasting and keto require dietary restrictions. | Strict dietary restrictions can be difficult to maintain and may lead to nutrient deficiencies. |

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Intermittent fasting and keto are the same thing. | While both approaches involve restricting certain foods, they are not the same. Intermittent fasting involves cycling between periods of eating and fasting, while keto is a low-carb, high-fat diet that aims to put your body into a state of ketosis. |
| You have to choose one or the other – you can’t do both intermittent fasting and keto at the same time. | It’s possible to combine these two approaches for even greater benefits. For example, some people follow a ketogenic diet during their eating window when practicing intermittent fasting. However, it’s important to consult with a healthcare professional before combining these two methods as it may not be suitable for everyone. |
| Both approaches will automatically lead to weight loss without any effort on your part. | While both intermittent fasting and keto have been shown to aid in weight loss, they still require effort on your part such as making healthy food choices and being consistent with your approach. |
| These approaches are only beneficial for weight loss purposes. | While weight loss is often cited as a benefit of these methods, there are many other potential health benefits including improved insulin sensitivity, reduced inflammation levels in the body, increased energy levels and mental clarity among others. |
| These approaches aren’t sustainable long-term. | With proper planning and guidance from healthcare professionals or registered dietitians/nutritionists (RDNs), both intermittent fasting and keto can be sustained long-term if desired by an individual. |
