Prolonged fasting, or intermittent fasting is a way of life.
You eat meals in intervals, and you space out the time in which you consume calories.
A standard day would look like breakfast and dinner. I break my day into half, so I eat a breakfast and a dinner and no lunch in-between.
At one point I would only eat once a day, I would recommend that everyone make informed decisions and make sure they stay hydrated. Even the “science,” on eating 3-6 meals a day is vague and misleading. For me it has always been about calories in vs. calories out.
The quality of your food matters more than the quantity.
You need to make sure that you are getting the things that your body needs and one of those is calories. I got injured a few years ago and haven’t been able to workout for a few years, the diet has helped me maintain abs without ever working out. When you are fasted your body burns fat sources first for fuel.
So fasting during the day helps you burn more calories.
