Fasting is a practice that has been adopted since ancient times to improve health and longevity. Intermittent Fasting (IF) has been linked to various health benefits, including weight loss, improved metabolic health, increased longevity, and cognitive function. Additionally, research suggests that IF can help reduce blood glucose levels.
Among the various fasting protocols, the 15/9 intermittent fasting has recently gained significant popularity for its potential health benefits and simplicity. This comprehensive guide will delve into what it entails, its potential benefits and drawbacks, how to get started, meal plan suggestions, frequently asked questions, and key takeaways.
What is the 15:9 Intermittent Fasting?
15/9 intermittent fasting is a type of fasting that involves fasting for 15 hours straight, followed by an eating window of 9 hours each day. During the fasting period, only non-caloric beverages such as water, herbal tea, or other similar drinks exist allowed, while food consumption is limited to the designated 9-hour window. This method aids in calorie limitation intake during the eating window progress and controls your weight management effectively.
Can You Lose Weight by Fasting 15 Hours a Day?
Fasting for 15 hours a day can indeed contribute to weight loss by creating a calorie deficit. During the fasting period, the body may tap into stored fat for energy, aiding in fat loss over time. Additionally, the restricted eating window may help control overall calorie intake, supporting weight management goals.
Research suggests that intermittent fasting, including the intermittent fasting 15/9 approach, can contribute to weight loss by promoting fat-burning and reducing overall calorie intake. By restricting the eating window, individuals may naturally consume fewer calories, leading to weight loss over time when combined with a balanced diet and regular physical activity.
How to Get Started With 15/9 Intermittent Fasting
Getting started with 15/9 intermittent fasting involves gradually adjusting your eating schedule to fit within the designated window. Begin by extending your fasting period by 30 minutes to an hour each day until you reach the desired 15-hour fasting window.
To initiate your journey with 15/9 intermittent fasting, follow our 9 straightforward steps to begin:
Step #1: Choose Your Eating Window
Start by selecting a 9-hour period during which you'll consume your meals and snacks. This timeframe can be tailored to fit your daily routine and preferences. Common options include 10:00 a.m. to 7:00 p.m. or 12:00 p.m. to 9:00 p.m.
Step #2: Establish Your Fasting Period
Dedicate the remaining 15 hours of the day to fasting, including your sleep time. For example, if your eating window is from 10:00 a.m. to 7:00 p.m., your fasting period the next day would extend from 7:00 p.m. to 10:00 a.m.
Step #3: Stay Hydrated
It's essential to remain hydrated throughout the fasting period. Drink water, herbal tea, or electrolyte-infused water without added sugars or calorie-laden creamers. Aim for a daily water intake of approximately 2.5 liters (85 fluid ounces) to help control hunger.
Step #4: Plan Balanced Meals
Opt for well-rounded meals packed with essential nutrients. Include foods like fruits, vegetables, lean proteins, and whole grains in your meals while avoiding heavily processed or sugary options.
Step #5: Incorporate Supplements
Pay attention to your body's signals of hunger and fullness. Avoid overeating during your eating window and stop eating when you feel satisfied.
Step #6: Listen to Your Body
If you're new to intermittent fasting, consider gradually increasing your fasting window over several days or weeks to allow your body to adapt. Begin by extending your fasting period by 30 minutes to an hour each day until you reach the desired 15-hour fasting window. Begin with a 12-hour fasting window and gradually extend it to 15 hours.
Step #7: Gradually Extend Your Fasting Period
Consistency is crucial for seeing results with intermittent fasting 15/9. Stick to your chosen eating and fasting windows as closely as possible.
