What Is The 80/20 Rule Diet?
The 80/20 rule diet is not strictly a diet plan. It, instead, is a way of eating and a lifestyle where you consume nutritious meals 80% of the time and relax food restrictions the remaining 20% of the time. This method helps you adopt healthier eating habits and balances your nutritional requirements.
While how it is to be practiced is open to individual interpretation, this diet is also called the weekend diet as you can eat your favorite foods for two days after eating healthy foods for five days in a row. This idea goes against the theory of dieting, which can often cause side effects. One study notes that, in some cases, dieting may backfire and lead to binge eating (1). However, the 80/20 rule diet can save you from such restrictions as it offers a diverse menu.
A carefully planned 80/20 rule diet can give you the best of both worlds. Read more to learn how this diet can help you in your health journey.

These features make this diet perfect for those who are new to dieting and want to start eating healthy. It can help kickstart your health journey and take you a step closer to your goal. That said, one of the most common goals of this diet is weight loss. But how well does it work for weight loss? We will discuss the same in the next section.
Does The 80/20 Rule Diet Work For Weight Loss?
The efficacy of the 80/20 rule diet plan for weight loss depends on various factors. A week-long healthy eating and abstinence from junk food may result in some weight loss, but there’s a catch – you may regain the lost weight over the weekend.
A study published in the journal Obesity (Silver Spring) observes that changes in lifestyle (diet or activity-related) during the weekend may prevent weight loss. It concludes that higher energy intake over a short period, such as on weekends, could lead to significant weight gain (2).
These findings may make the 80/20 rule diet seem a lot more appealing than effective. However, more research specific to its principles of healthy and balanced eating is warranted to arrive at any conclusion about its efficacy.
Nevertheless, this diet can still serve as a starting point for those who are trying to break free from unhealthy eating patterns. Keep reading to discover ways to make the right calculations with respect to this diet.
How To Calculate The 80/20 Rule Diet
Remember that the 80/20 rule diet is not set in stone. You can modify it as per your requirements while eating nutritious meals 80% of the time and relaxing the restrictions the remaining 20% of the time. You can follow any of the following approaches.
- Weekdays Versus Weekends
Eat foods rich in healthy fats, fiber, and minerals for five days of the week and your other favorite foods in the next two days. However, this approach may be counterproductive for some as it may lead to heavy calorie intake on weekends. You may prevent this by setting a few boundaries to keep yourself from binge eating in that short window.
- Counting Total Number Of Meals Per Week
Divide the total number of meals in a 7-day week and distribute them in an 80/20 ratio. For example, breakfast, lunch, snack, and dinner make for 4 meals a day and 28 meals a week. So, you can have 22 healthy meals and 6 indulgent ones throughout the week.
- Mixed Approach
Instead of eating a lot of junk food at a time, you may have it with every meal, and in moderation. Divide your daily calorie intake as per an 80/20 ratio. For example, if your daily caloric requirement is 1,600 calories, take 1,280 calories from healthy foods and the remaining 320 calories from other foods. You may also bend the rules and make it 90/10 to satisfy your cravings while limiting the intake of junk foods.
The main idea is to keep your meals as healthy as possible 80% of the time so that you get to indulge the remaining 20% of the time without any guilt. However, you need to be aware of the differences between healthy and unhealthy or “indulgent” foods to make better choices. For example, while white bread is healthier than chips, it is less healthy than whole wheat bread as it has less fiber (3). Hence, your aim is to make your diet as healthy as possible by selecting more nutritious food options. Dive into the next section to learn about the right foods you can include in your 80/20 rule diet.
