Prolongation of overnight fast, which depends not only on timing of breakfast but also on timing of the last meal of the day, can be beneficial (59).” Furthermore, fasting should entail “undernutrition without malnutrition” to yield benefits; otherwise, it can be labeled starvation (58). As Dr. Jason Fung puts in one of his blogs, the difference between fasting and starvation is a matter of willingness, i.e., if a person is willingly or unwillingly abstaining from food.

Dr. Dom D’Agostino, a well-known ketogenic diet researcher, suggests doing a longer intermittent fast for 3 days, 3 times a year. To implement an intermittent fast, simply restrict eating until 12 pm the next afternoon (yes, sleeping time counts as fasting time). The whole point of intermittent fasting is to allow ourselves to increase the amount of food we can intake at one time. You also won’t experience problems with an eating window approach. You can also adjust your eating window so that when you eat suits your lifestyle. This can be a problem for people who work at that time. What’s really great is that compared to low-calorie diets, fasting does not lead to muscle wasting and leads to over 7 pounds more compared to low-calorie diets (26). The most basic definition of intermittent fasting is willingly abstaining from calories for a defined period of time. Intermittent fasting (IF), also called intermittent energy restriction, is an umbrella term for a range of dietary practices that involve defined periods of fasting and feeding. Over time, this causes your body to enter ketosis, a metabolic state in which your body relies on fat instead of sugar9 as its main source of energy. Around three hours or so after your meal, your body shifts2 to the early fasting state, which lasts until about 18 hours after the beginning of your fast. Over the next 24 to 48 hours of fasting, gradually increase the quantity and variety of foods, focusing on nutrient-dense options that are easy on your digestive system. While both strategies promote metabolic health, intermittent fasting is commonly used for long-term maintenance, helping to stimulate fat metabolism and support weight management. Extended fasting, lasting 36 hours or more, significantly reduces glycogen stores and insulin levels, triggering ketosis. The medium chain triglycerides and caffeine in the coffee will help increase your ketone levels, and the fats will help satiate you while giving you a ton of energy.

In addition to accelerated fat burning, the body undergoes remarkable changes in immune system function during the final stages of an extended fast lasting up to 72 hours. Between 24 and 36 hours of fasting, the liver starts to burn fat more effectively. After around 10 hours of fasting, blood sugar and glycogen levels are declining, which inhibits the release of insulin, a critical metabolic hormone involved in blood sugar regulation and fat storage. In contrast, fasting is a controlled and deliberate practice that shifts the body from using sugar and carbohydrates as fuel sources to burning fat to generate energy. You can have them all on an intermittent fasting diet. You can break down fasting into feeding, postabsorptive, gluconeogenesis, ketosis, and protein conservation stage. For this reason, intermittent fasting is no stranger to bodybuilders. In addition, according to studies, starting from three-day fasting, the body undergoes an almost complete immune system rejuvenation. The fourth stage of fasting, according to Dr. Cahill, is ketosis.

Suppose you’re fasting for an extended period. This way, you don’t have to consume glycogen for 1-2 days before burning fat efficiently. The standard keto diet encompasses 70% to 80% energy from fats, 10% to 20% from proteins, and 5% to 10% from carbohydrates. The ketogenic diet reduces the number of carbs eaten per day. The main purpose of this combination is to reach ketosis, which is a state where you burn mostly fat instead of glucose for energy (1). The early fasting stage begins immediately after a meal and lasts until about 4 hours afterward. However, a study published in Obesity found that eating 6 small meals a day did not increase fat burning and may even increase hunger and desire to eat (64). You may want to start out with fasting for 12 hours first and then increasing your fasting time in a stepwise fashion. Intermittent fasting and the keto diet have one major thing in common – they can both get you into ketosis.
