Intermittent Fasting Statistics

#1. Fasting may be more useful than regular calorie restriction for many overweight patients because of greater loss of body fat, and better preservation of muscle. (PubMed)

#2. Research indicates that time-restricted feeding patterns such as the 16/8 method may prevent hypertension and reduce the amount of food consumed, leading to weight loss. (NCBI)

#3. A study found that when combined with resistance training, the 16/8 method helped decreased fat mass and maintain muscle mass in male participants. (NCBI)

#4. 24 percent of US adults say they’ve tried intermittent fasting for weight loss. (YouGov)

#5. Intermittent fasting is seen as an inexpensive dieting option according to Americans. (YouGov)

Intermittent Fasting Benefits Statistics

#6. Intermittent fasting help modify risk factors for health conditions like diabetes and cardiovascular disease, such as lowering cholesterol and blood sugar levels. (Clinical Nutrition ESPEN)

#7. Fasting for up to 24 hours can lead to a metabolic shift that causes your body to use fat as an energy source instead of glucose. (PubMed)

#8. Time-restricted feeding cycles may have a variety of other health benefits. Studies show that time-restricted feeding cycles can prevent diabetes, slow tumor progression, delay aging, and increase lifespan in rodents. (PubMed)

#9. A hormone that’s altered during a fast is human growth hormone (HGH), levels of which may increase as much as five-fold. (PubMed)

#10. Restricting meals to a six-hour window that ended at 3 P.M. led to better insulin sensitivity and blood pressure even without weight loss. (Science Direct)

#11. Almost nine in 10 (87%) people who have tried intermittent fasting to lose weight say that this diet was very effective. (YouGov)

#12. Fasting improves metabolism, lowers blood sugar levels; lessens inflammation, which improves a range of health issues from arthritic pain to asthma; and even helps clear out toxins and damaged cells, which lowers risk for cancer and enhances brain function. (Harvard Health)

#13. One 16-week study in obese men found that those who practiced intermittent fasting lost 47% more weight than those who continuously restricted calories. (PubMed)

#14. Studies have shown that intermittent fasting reduces markers of inflammation, such as C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), interferon gamma (ifnγ), leptin, interleukin 1 beta (IL-1β), and interleukin 6 (IL-6). (PubMed)

#15. Fasting may promote autophagy, a process in which your body breaks down and recycles old, potentially dangerous parts of your cells. (PubMed)

#16. Several animal studies suggest that autophagy may help protect against diseases like cancer, Alzheimer’s, and heart disease. (PubMed)

#17. There is some evidence that water fasting may lower the risk of chronic diseases like diabetes, cancer, and heart disease. (PubMed)

#18. In one study, 30 healthy adults followed a water fast for 24 hours. After the fast, they had significantly lower blood levels of cholesterol and triglycerides — two risk factors for heart disease. (PubMed)

#19. A study in healthy adults found that restricting calorie intake to a 4-hour time period in the evening led to significantly greater body fat loss than when eating three separate meals throughout the day. (PubMed)

Alternate Day Fasting Statistics

#20. A randomized pilot study comparing alternate-day fasting to a daily caloric restriction in adults with obesity found both methods to be equally effective for weight loss. (PubMed)

#21. Another study found that participants consumed 35% fewer calories and lost an average of 7.7 pounds (3.5 kg) after alternating between 36 hours of fasting and 12 hours of unlimited eating over 4 weeks. (Cell)

#22. Research shows that combining alternate-day fasting with endurance exercise may cause twice as much weight loss than simply fasting. (PubMed)

#23. Research shows that alternate-day fasting trials lasting 3–12 weeks, as well as whole-day fasting trials lasting 12–24 weeks, reduce body weight and body fat. (PubMed)

#24. Alternate-day fasting improves the body’s response to insulin by more than twice as much as a typical calorie-cutting diet. (Wiley)

#25. In a study in people practicing alternate-day fasting for the religious holiday of Ramadan, proinflammatory cytokines were significantly lower during the alternate-day fasting period, compared to the weeks before or after. (PubMed)

Extended Fasting Statistics

#26. 48 hour fasts are linked to health benefits like increased insulin sensitivity, cellular repair, and weight loss. (PubMed)

#27. Appropriately spacing out your 48-hour fasts may offer greater health benefits. (PubMed)

#28. Extended fasts may slow cell aging. Cellular repair is your body’s natural way of replenishing its cells. It may help prevent disease and even delay tissue aging. (PubMed)

#29. Fasting for more than 24 hours may lower inflammation by reducing oxidative stress in your body’s cells. (Cell)

#30. During a fast of 24 or more hours, glycogen — the storage form of carbs — is depleted and insulin levels are reduced. This allows your body to burn mostly fat for energy, making stored body fat more available for use. (PubMed)

#31. Many studies note that various types of fasting, including 48-hour fasting, may decrease insulin levels. What’s more, they improve insulin sensitivity, which allows your body to transport blood sugar more efficiently. (PubMed)

#32. One study in 10 people with type 2 diabetes found that 12–72-hour fasting decreased fasting blood sugar levels by up to 20% after a single fast. (PubMed)

#33. Fasts lasting longer than 24 hours may have additional benefits for blood sugar control beyond those linked to shorter fasts. (Annual Review Of Nutrition)

Fasting Mimicking Diet Statistics

#34. Fasting Mimicking Diet triggers “autophagy,” your body’s natural way of cleaning house. Your cells clean and recycle old and damaged parts, resulting in a profound benefit — cellular rejuvenation. (Valter Longo)

#35. The Fasting Mimicking Diet helps you maintain healthy systolic blood pressure. (Valter Longo)

#36. The Fasting Mimicking Diet helps kickstart weight loss, supports healthy metabolic balance and rejuvenation from within. (Valter Longo)
