Unlock Weight Loss Success: Shed More Pounds with a 3-Day Diet Plan

For those weary of constant calorie counting, a new dietary approach might offer a more manageable path to weight loss. Emerging research suggests that the 4:3 method, which integrates intermittent fasting with calorie reduction, can lead to significant weight loss by dieting just three days a week. This approach could potentially allow individuals to lose up to 60% more weight compared to traditional daily calorie restriction.

The 4:3 intermittent fasting (IMF) method involves reducing calorie intake by 80% on three nonconsecutive days each week, while allowing unrestricted eating on the remaining four days. According to the Cleveland Clinic, determining the appropriate calorie intake for fasting days involves calculating one’s basal metabolic rate (BMR), which is “the number of calories your body needs to function at a basic level” to maintain its current weight.

On average, a female participant with a BMR of 1,410 calories per day would consume just under 300 calories on fasting days. To visualize, this is roughly equivalent to a medium-large apple with two tablespoons of peanut butter. Despite the freedom on non-fasting days, participants are encouraged to maintain a healthy diet.

The study, published in the Annals of Internal Medicine, involved 165 participants, predominantly female, with an average age of 42 and a mean body mass index (BMI) of 34.1. Participants were divided into two groups: one following the 4:3 IMF diet and the other adhering to a daily calorie restriction of 34%. Both groups received free gym memberships and were encouraged to exercise for at least 300 minutes weekly. They also participated in group-based behavioral support and received dietary guidance focused on macronutrient goals.

After 12 months, the 4:3 IMF group lost an average of 7.6% of their body weight, compared to a 5% loss in the daily calorie restriction group. As reported by ABC News, this equates to an average weight loss of 17 pounds for the 4:3 group, which is 60% more than the other group. Additionally, the 4:3 group experienced improvements in systolic blood pressure, cholesterol levels, and fasting glucose levels.

Danielle Ostendorf, PhD, a co-author of the study, highlighted the practicality of the 4:3 method, describing it as “a sweet spot.” She explained, “With this 4:3 approach, where they’re fasting three days a week (which are flexible and can be worked around a personal schedule), it might be a middle ground where they feel like they can adhere to it, and it’s feasible to implement in their daily lives.”

Victoria Catenacci, MD, the study’s lead author, noted that participants in the 4:3 group “were more adherent” to the diet and more likely to continue with the plan until its conclusion.

Before embarking on any new diet, especially one involving significant calorie restriction, consulting with a healthcare provider is crucial. The study focused on healthy adults, and there’s no data on weight maintenance post-study. Catenacci emphasized the need for further research to assess the safety and efficacy of this method for specific populations, such as older adults and individuals with certain health conditions.

Ostendorf expressed the desire to develop a comprehensive 4:3 IMF program for clinics and community programs, making it more accessible and affordable for the public.
