Introduction
Intermittent fasting has been buzzing lately in the fitness and weight loss scene. Influencers and fitness experts everywhere are raving about this magic: “No need to count calorie intake or eat a salad every meal! Restrict your eating window, and the pounds will shed away!” Countless intermittent fasting methods, like 16:8, 5:2, and alternate-day fasting, have flooded the internet, overwhelming people.
The question is: is intermittent fasting right for everyone? Which method is the easiest to stick to and most effective? And is it science-backed weight loss, or just another overhyped trend? Let’s explore the truth behind intermittent fasting and find out if it lets you “eat your way slim!”
What is intermittent fasting?
The core principle of intermittent fasting is time-restricted eating. You should consume all your daily required calories within a specific eating window and remain fasting for the rest of the day. During fasting, you may consume calorie-free beverages such as water, coffee, or tea to alleviate hunger.
The essence of intermittent fasting is to stabilize blood sugar levels and increase the rate of fat burning by prolonging the fasting period while maintaining the same calorie intake. Ultimately, creating a calorie deficit remains the fundamental rule of weight loss. If you overeat during your eating window, intermittent fasting will not work.
Intermittent fasting methods
Do you want to try intermittent fasting but are unsure which method is best for you? Here are the most popular methods, including how to implement them and their pros and cons, to help you choose the best one.
- 12-hour fasting(overnight fasting): It requires a daily 12-hour fasting window. For example, you can end your meal at 7 pm and resume at 7 am the following day. It’s the easiest one because you don’t have to skip any meals. All you need to do is avoid bedtime snacks. For people who never try intermittent fasting, it’s a good way to start and stick to it. Most of the fasting time takes place during sleep time. However, 12 hours fasting is not as effective as other intermittent methods. The smaller the fasting window, the slower the effect of weight loss.
- The 16:8 method: The 16:8 fasting method involves consuming all your daily calories in eight hours and fasting for 16 hours. Some researchers suggest that women should not fast for more than 14 hours for hormonal reasons. Most people choose to eat between 9 am and 5 pm. It’s suitable for those who eat dinner earlier because they don’t necessarily skip a meal. But for office workers, by the time they get off work, they’ve missed their eating window. It will usually cause people to skip breakfast or dinner. Research has found that the 16:8 method can help higher-weight person manage their weight and blood sugar better.
- The 5:2 method: The 5:2 method is you eat normally for 5 days and restrict intake to 500-600 calories for the rest of 2 days. Women can take 500 calories; Men can take 600 calories. For five days, you can eat whatever you want and don’t have to count calories. You can choose any 2 days for fasting. But the problem is that after two days of fasting, your minimal calorie intake will leave you extremely hungry. This will make it very hard to stick to it. It is also important to note that you do not exercise vigorously on fasting days, as your energy will not support your exercise.
- 24-hour fasting method: 24-hour fasting is when you eat once a day. It can be breakfast, lunch, or dinner. If you choose to eat dinner, you can’t eat until the next day’s dinner. People will usually do it 1-2 times a week. After fasting, people should return to their regular diet and get the necessary nutrients. You can’t get all the calories you need for the day in one meal, enabling you to create a calorie deficit for weight loss. It fits your schedule because you can still enjoy a nice meal with your family and friends. It’s tough to stick to it, but during fasting, you can drink water, coffee, and other calorie-free drinks to alleviate hunger. The lack of nutritional intake prevents the body from functioning correctly. People may feel fatigue, headaches, or irritability. However, others have found that these symptoms lessen over time.
- Alternate-day fasting: People fast every other day. They can consume 500-600 calories on fasting days and eat regularly on non-fasting days. You can feel extremely hungry, but as time progresses, your hunger will lessen in the second week, and you will feel satisfied after the fourth week. It’s still challenging to stick to it because you can only consume small amounts of calories and never feel full. It might not be good for beginners or people with certain medical conditions.
Who should avoid intermittent fasting?
Although intermittent fasting can be an effective tool for weight loss, it’s not suitable for everyone. It’s not recommended for people who have suffered from or are currently suffering from eating disorders, as it could exacerbate their symptoms. Children, people with underlying health conditions, and pregnant or breastfeeding women may also be unsuitable for intermittent fasting. To ensure safety, it is highly recommended that people consult a doctor or registered dietitian before starting intermittent fasting to develop a personalized plan under professional guidance.
Common mistakes (why do some people fail with intermittent fasting?)
Based on your current healthy eating habits, it is recommended to appropriately incorporate intermittent fasting by restricting your eating window to boost metabolism. This combined approach can more effectively support weight loss and enhance overall health. However, avoid the following common mistakes that lead to failure.
- Have a craving for food: Intermittent fasting requires self-discipline. When we restrict the eating window to 8 hours or even a single meal, some people may feel hunger, dissatisfaction, and even low spirits. Moreover, the accumulated hunger during fasting can intensify food cravings, leading many to overeat when they resume eating. Therefore, Controlling appetite and stabilizing emotions is crucial.
- Improper dietary choice: Dietary choices are especially critical after ending a fast. If you consume ultra-processed foods that are low in protein and fiber, not only will it not reduce satiety, but it may also lead to excess calorie intake. To maximize the function of intermittent fasting, it is recommended to consume a variety of nutrient-dense whole foods that prolong satiety and effectively boost metabolism.
- Too extreme fasting: When you adopt too extreme fasting, the calories you consume are much less than your basal metabolic rate will cause metabolic damage. The body will enter a metabolic adaptation state, a survival defensive mechanism. It will store the calories you consume and slow down your metabolism. It often leads to weight rebound and makes it harder to lose weight. Developing healthier lifestyle habits is the only way to sustain long-term health and well-being.
Conclusion
Intermittent fasting can be a powerful tool for weight loss. Facing a variety of fasting methods, it’s essential to choose the method that best aligns with your personal situation and lifestyle.
