A growing number of experts have stated that Intermittent Fasting (IF) in short bursts can increase fat burning and improve our health. But what exactly is IF? Some use IF by only eating during an 8-12 hour window each day and fasting the remainder 24 hours. Others may fast for a 24-hour period every so often. Then there are dietary protocols that choose 1-2 calorie restricted days per week, with the remainder days eating your usual calorie intake.
Regardless of the protocol used the evidence has shown there are benefits and downsides, with a moderate approach tending to produce better outcomes. Fasting may be more beneficial for overweight people and metabolic disorders. The negatives may more likely affect athletes, highly active people, those with high stress or poor eating habits. In some women fasting can negatively affect hormone levels, particularly the more restrictive the protocol.

Unfortunately, there is no simple answer on whether IF will work for you. It’s important to do your research from scientific-based evidence if you are going to give it a try, and know that you will need to experiment to see if it works for you.
