One of the most popular and effective weight control methods is IF, or Intermittent Fasting. It involves setting structured periods for eating and fasting, helping to reduce calorie intake, boost metabolism, and regulate blood sugar levels. For those who are new to IF, this article compiles beginner-friendly methods that are easy to understand and practical to follow.
Beginner IF Method: The Popular 16/8 Approach
This method is widely popular because it is simple and does not significantly disrupt daily life. It is suitable for those who want to start without pushing themselves too hard. The basic principles are as follows:
- Principle: Fast for 16 hours and eat within an 8-hour window each day
- Example: Eating between 12:00–20:00
- Suitable for: Beginners who want to adjust their eating habits without feeling overly hungry
For those who want an easier approach or a more challenging variation, there are several IF methods that can be adapted to different lifestyles. Whether you prefer a gradual start or a more intensive approach, you can adjust the level of difficulty as needed.
A Complete Guide to IF Methods for Beginners to Advanced Levels
12/12
- A simple starting method, such as eating between 8:00–20:00 and fasting for 12 hours
- Helps the digestive system rest and allows the body to begin fat-burning
- Suitable for beginners who are not ready for long fasting periods
14/10
- Fast for 14 hours and eat within a 10-hour window, such as 10:00–20:00
- An upgrade from 12/12, allowing longer fasting and increased fat burning
- Suitable for those who are getting familiar with IF
18/6
- Fast for 18 hours and eat within 6 hours, such as 13:00–19:00
- Helps the body enter the fat-burning zone more quickly
- Requires careful food selection to ensure sufficient nutrient intake within the shorter eating window
20/4 หรือ OMAD (One Meal A Day)
- Eat only one meal within 4 hours, such as 17:00–20:00, or sometimes just dinner
- Not recommended for beginners, as it may lead to fatigue
- Suitable for experienced IF practitioners or those following a ketogenic diet and not engaging in heavy physical activity. Proper nutritional planning is essential to prevent deficiencies and weakness
Regardless of the IF method chosen, avoid snacking during fasting periods and prioritize the nutritional quality of meals. Planning according to your lifestyle helps ensure adequate energy intake and supports safe, sustainable weight loss.
In addition, there are two other IF methods suitable for those who want more flexibility or prefer a more intensive approach. Let’s take a look at what they are.
5:2 IF – Flexible Without Daily Fasting
A popular option for those who do not want to fast every day. It offers flexibility without excessive pressure. The challenge lies in controlling calorie intake on restricted days.
- Principle: Eat normally for 5 days and limit intake to 500–600 calories on the remaining 2 days
- Example: Choose Monday and Thursday as low-calorie days
- Suitable for: Those who prefer not to fast daily but can control calorie intake on certain days
- Benefits: Supports weight loss, insulin control, and metabolic balance
This method reduces calorie intake to about 25% of daily needs (approximately 500–600 kcal), compared to average requirements (around 2,000 kcal for women and 2,400 kcal for men). It is not complete fasting but structured calorie reduction.
Eat-Stop-Eat: 24-Hour Fasting Once or Twice per Week
A more intensive IF approach that involves fasting for a full 24 hours. Suitable for experienced individuals aiming for more noticeable results.
- Principle: Fast for 24 hours, 1–2 times per week (non-consecutive days)
- Example: Eat dinner on Monday, then fast until dinner on Tuesday
- Suitable for: Those with prior IF experience seeking stronger results
- Benefits: Enhances metabolism, supports weight loss, and may improve blood pressure and blood sugar levels
However, this method may not be suitable for individuals with underlying health conditions, low blood pressure, pregnant women, children, or those with eating-related issues. Extended fasting may cause intense hunger, mood swings, or fatigue, especially for those with high daily energy demands. Proper assessment is recommended before starting.
Tips to Make IF More Effective for Beginners
Although IF is popular because it does not require strict calorie counting, it demands discipline and appetite control, especially during the adjustment phase. The following tips can help:
- Drink more water to promote fullness, reduce hunger, and support metabolism
- Focus on foods that keep you full longer, such as protein, healthy fats, and fiber
- Get enough sleep to reduce hunger-related hormones and improve appetite control
- Plan meals in advance to stay consistent and manage calorie intake effectively
- Consult a doctor if unsure about which method to start or how to adjust your lifestyle

Another option is slimming pens using the medication Liraglutide, which can help control appetite. This medication works similarly to the GLP-1 hormone that regulates satiety in the body, helping you feel full sooner and eat less. However, it should only be used under prescription from a qualified doctor at a hospital or a certified clinic.
What is Liraglutide?
Liraglutide is a medication that acts similarly to the GLP-1 hormone naturally produced by the body after eating. It sends signals of fullness to the brain, helping you feel full faster, eat less, and reduce appetite—especially during periods of strict dietary control while doing IF.
This medication has been approved for safety by the U.S. Food and Drug Administration (FDA) and the Thai Food and Drug Administration (Thai FDA) for weight management. When used correctly under medical supervision, it can support safe and more effective weight loss.
Where can you buy Liraglutide? Is it safe?
Liraglutide is a prescription medication that must only be used under a doctor’s supervision. For those interested, the following recommendations should be followed:
- Do not purchase from unauthorized online sources that are not clinics or hospitals, as Liraglutide requires a doctor’s prescription. Buying online carries risks of receiving substandard or unsafe products.
- Choose licensed hospitals or clinics to ensure the medication is genuine and meets proper standards.
- Receive guidance from a doctor, including proper evaluation, planning, and close monitoring of usage to ensure safety, reduce the risk of side effects, and achieve optimal effectiveness.
Fat-dissolving injections for targeted fat reduction alongside IF
For some individuals with localized fat, Meso Fat are another popular option, as they can break down fat in specific areas within 1–2 weeks. This helps reduce the burden of doing IF, making it easier to manage. If combining with a weight loss program, it is recommended to consult a doctor thoroughly to ensure safety and achieve the desired results.
