Tips for Thought

Intermittent fasting is an eating pattern that cycles between periods of eating and fasting. There are many different ways to do intermittent fasting, but they all involve restricting food intake for a set time each day or week.

How does intermittent fasting work?

When you eat, your body produces insulin, a hormone that helps your cells absorb glucose from your blood. When you fast, your insulin levels go down, and your body starts to break down stored fat for energy. This can lead to weight loss, as well as other health benefits.

What are the methods?

  • 16/8 method. This is one of the most popular intermittent fasting methods. You fast for 16 hours and eat during an 8-hour window. For example, you might eat your last meal at 8 pm and only eat again at noon the next day.
  • 5:2 method. This method involves eating normally for five days of the week and then fasting for two days. You can eat no more than 500-600 calories on fasting days.
  • Alternate-day fasting. This method involves fasting 24 hours every other day. You can eat no more than 500-600 calories on fasting days.
  • Warrior diet. This method involves eating only one large meal per day. You can eat this meal whenever you want, but it is typically eaten in the evening.

Here is a peek into a day in the life of someone who follows the 16/8 method. 

Breakfast: Skip breakfast.

Lunch: Eat a healthy lunch at noon, such as a salad with grilled chicken or fish.

Dinner: Eat a healthy dinner at 8 pm, such as roasted vegetables with quinoa and tofu.

Snacks: If you feel hungry during fasting, you can have healthy snacks such as nuts, seeds, or fruits.

Here is a day in the life of someone who follows the 5:2 method.

Monday: Eat normally.

Tuesday: Eat normally.

Wednesday: Fast. You can have up to 500-600 calories on this day.

Thursday: Eat normally.

Friday: Eat normally.

Saturday: Fast. You can have up to 500-600 calories on this day.

These are just two examples of intermittent fasting schedules. There are many other variations, so you can find one that works best. It is important to listen to your body and adjust your schedule as needed.
