One of the more popular fad diets recently that has stuck around, other than the keto diet, has been the idea of intermittent fasting. People use intermittent fasting to improve their health, simplify their life, and lose weight. Some studies suggest that it may even help you live longer. Although, not many people know everything about it so below is a general overview of intermittent fasting.
What is Intermittent Fasting?
Intermittent fasting is an eating pattern where you cycle between eating and fasting. There are no foods that you are supposed to avoid rather you choose when you are going to eat. People consider intermittent fasting to be an eating pattern rather than a diet because it isn’t a diet in the conventional sense since it doesn’t tell you what foods not to eat.
Intermittent Fasting Methods
There are lots of different ways that you can do intermittent fasting and all of them involve splitting the day or week into a cycle of fasting and eating periods. During the fasting periods you choose where you eat very little or nothing at all. Most people do nothing at all or they just do a green or red drink.
The most popular methods are:
- The 16/8 method: In this method you fast for 16 hours and then eat over the course of 8 hours. For example, only eating from 12-8pm. They key to this method is being consistent and not eating until 16 hours have past since the last time you ate.
- Eat-Stop-Eat: In this method you fast for 24 hours once or twice a week.
- The 5:2 diet: In this method you only consume 500-600 calories on two non-consecutive days during the week and then eat normally on the other 5 days.
All of these methods should cause weight loss as long as you don’t compensate by eating a lot more during the eating periods because the idea is you are trying to reduce your calorie intake. The most popular of the three methods is the 16/8 method because it is the simplest, easiest, and most sustainable for most lifestyles.
How Does It Affect Your Body?
When you fast, many things happen in your body at the cellular and molecular level. Here are some of the changes that occur in your body:
- Your body adjusts your hormone levels to make stored fat more accessible.
- Your cells initiate important repair processes and changes the expression of genes.
- The levels of growth hormone rise steeply sometimes increasing as much as 5-fold. This benefits for fat loss and muscle gain.
- Insulin sensitivity improves and levels of insulin drop significantly which helps make stored fat more accessible.
- When fasting your cells initiate cellular repair processes, including autophagy which is where cells digest and remove old proteins that build up in cells.
- There are changes in the function of genes that are related to longevity and protection against disease.
These changes at the hormone levels, gene expression, and cell function are responsible for the health benefits that come along with intermittent fasting.
Side Effects
Some evidence from studies suggests that intermittent fasting may not be as beneficial for women. Also, you should seek a medical consultation with your doctor before trying intermittent fasting if you:
- Have diabetes
- Have problems with blood sugar regulation
- Have low blood pressure
- Take medications
- Are underweight
- Have a history of eating disorders
- Are a woman trying to conceive
- Are pregnant or breastfeeding
This being said if you are healthy there is nothing dangerous about not eating if you are well-nourished overall.
