Study Reveals Intermittent Fasting Is Just As Effective As Calorie Counting

A recent study published in the Annals of Internal Medicine sheds light on the effectiveness of different weight loss methods. Contrary to popular belief, the research reveals that restricting eating to a specific time frame, known as intermittent fasting, is no more advantageous than simply counting calories.

The University of Colorado conducted a trial involving 90 adults, who were divided into three groups. The first group had the freedom to eat whenever they wanted but reduced their caloric intake by 25%. The second group practised intermittent fasting, consuming all their calories within an eight-hour window. The control group maintained their regular eating routines without any alterations. Participants in both experimental groups adhered to their assigned diets and reported no adverse side effects.

Surprisingly, the findings demonstrated that participants who restricted their caloric intake, without restricting the time frame, consumed an average of 405 fewer calories per day and lost approximately 5.4 kilograms after one year. On the other hand, those who practised intermittent fasting consumed 425 fewer calories per day and lost about 4.5 kilograms. These results indicate that calorie counting remains the most effective approach for shedding unwanted pounds.

The study challenges the growing popularity of time-restricted eating (TRE) or intermittent fasting as a weight loss regimen. TRE has gained traction due to its simplicity and the absence of calorie counting requirements. Celebrities like Jennifer Aniston, Nicole Kidman, Cameron Diaz, and Mark Wahlberg have been known to follow variations of intermittent fasting, such as the 16:8 diet or the 5:2 diet.

Despite claims of improved blood sugar control, enhanced brain function, and increased lifespan, intermittent fasting may lead to overeating during the designated eating window, leading to weight gain. Previous research has also raised concerns about its impact on reproduction and fertility, as well as potential associations with cardiovascular disease.

This study contributes to the growing body of evidence suggesting that intermittent fasting is not inherently superior to calorie counting for weight loss. It emphasises the need for a comprehensive understanding of various weight loss strategies and highlights the importance of individual preferences and sustainable dietary habits when striving for healthy weight management.
