A recent study suggests that incorporating an additional daily cup of unsweetened coffee into your routine can aid in weight management. This research, published in The American Journal of Clinical Nutrition on October 1, revealed that this coffee-related benefit was nullified when a teaspoon of sugar was added to the brew. Interestingly, the addition of “cream or non-dairy coffee whitener” did not show any significant impact on weight, according to the study’s report.
Conducted by researchers from the Department of Nutrition at Harvard T.H. Chan School of Public Health in Boston, Massachusetts, this study utilized data from three prospective cohort studies spanning several years.
The research focused on establishing the connection between coffee consumption habits and fluctuations in body weight over four-year intervals. Participants provided information through questionnaires about their dietary choices, including coffee preferences, whether caffeinated or decaffeinated, and if sugar, non-sugar sweeteners, or cream were added to their coffee.
The findings indicated that adding one more cup of unsweetened coffee daily was associated with a reduction in weight by approximately 0.12 kilograms (0.26 pounds) over a four-year span. Conversely, participants who increased their daily coffee intake by one teaspoon of sugar gained approximately 0.09 kilograms (0.20 pounds) over the same period.
These associations between coffee consumption and sugar intake and changes in body weight were more pronounced among younger participants and individuals classified as overweight or obese.
Nutrition experts not involved in the study shared their perspectives on the findings with Fox News Digital. According to Erin Palinski-Wade, a registered dietitian based in New Jersey, increasing the consumption of a warm, low- to no-calorie beverage like coffee may promote weight management by enhancing the sensation of fullness, potentially leading to reduced overall calorie intake throughout the day. However, the addition of sugar to coffee could counteract this benefit by introducing extra calories without contributing to a sense of fullness.
On the other hand, certain creamers or whiteners may offer benefits. Palinski-Wade suggested that milk and creamer additions can provide protein and fat, which may help with satiety. Moreover, she noted that individuals are less likely to use excessive quantities of milk or creamer as they do with added sugar due to a preference for sweetness.
However, Palinski-Wade cautioned that the study only demonstrates an association, not causation. Those who add sugar to their coffee might also be more inclined to consume additional sugar in their diet, potentially affecting their body weight and health.
Kim Kulp, a registered dietitian-nutritionist and owner of the Gut Health Connection in San Francisco, noted that while the study indicates an association between sweetened coffee and long-term weight gain, it does not prove that a small amount of sugar added to coffee directly causes weight gain. She explained that a teaspoon of sugar contains only 16 calories and 4 grams of carbohydrates, which is unlikely to cause weight gain by itself. It may, however, reveal something about the preferences of those who prefer a touch of sweetness in their morning routine.
Kulp emphasized the complexity of weight management, suggesting that it involves more than just one food or drink choice. Factors such as overall diet and lifestyle should be taken into account.
In conclusion, it’s essential for individuals with dietary concerns or weight management goals to consult with healthcare professionals for personalized guidance.
