Are you looking to break through your fitness goals?
If so, then you may want to try intermittent fasting. This type of fasting can help with weight loss and muscle gain, among other things.
In fact, according to a study published in the National Library of Medicine, those who intermittently fasted for eight weeks saw significant improvements in their body composition, including a reduction in fat mass.
Of course, before you start any new diet or fitness plan, it’s always best to consult with your doctor first.
And while there are many different ways to do intermittent fasting, using an app can help make the process easier and more efficient.
In this article, we will discuss the 12 best intermittent fasting apps and what each one offers.
So whether you are just starting or are a seasoned pro, there is sure to be an app on this list that meets your needs!
What is intermittent fasting?
Intermittent fasting is a type of diet where you don’t eat for a certain amount of time, and then you eat again.
You can do it for different amounts of time, depending on what you want to achieve. Some people do it to lose weight, while others do it to build muscle.
It’s important to talk to your doctor before starting any new diet, though!
One of the best intermittent fasting methods is the 16/8 method. This means that you eat for 8 hours and then fast for 16 hours. You can do this by not eating after dinner and then not eating again until lunch the next day.
Similarly, you could eat from noon to 8 pm and then fast until noon the next day.
It’s important to note that you can still drink water, coffee, and other non-caloric beverages while fasting. In fact, drinking coffee or green tea during your fasting period can help boost your metabolism!
With that out of the way, let’s take a look at the 12 best intermittent fasting apps!
