Can Junk Food Speed Up Weight Loss? New Study Has To Say This

We've long been told that weight loss requires discipline and strict avoidance of temptations. But what if saying "yes" to that cookie now and then could actually help you reach your fitness goals faster? Yes, you read that right, and a new study is proving that.

Published in Physiology & Behaviour on March 15, 2025, the research led by Nouf W. Alfouzan and Manabu T. Nakamura from the University of Illinois Urbana-Champaign presents a surprising twist on the association between cravings and weight management. Rather than resisting every indulgence, the study finds that occasionally giving in to food cravings may actually support, not sabotage, weight loss.

What the study revealed

Tracking 30 adults over a period of 24 months, the researchers aimed to examine how cravings evolved during the weight loss journey. The participants, all attempting to lose weight, were observed for changes in both their eating habits and psychological responses to food.

And the study revealed that those who lost more than 5% of their body fat experienced a notable decline in cravings, especially for high-calorie comfort foods. Contrarily, individuals who failed to see measurable weight loss continued to grapple with strong urges for calorie-dense items like sweets, fried foods, and processed snacks.

Cravings can be managed — not erased

Rather than asking participants to cut out "cheat meals" entirely, researchers implemented a different approach. Small, mindful portions of desired foods were strategically incorporated into balanced meals. This tactic not only improved dedication to the overall dietary plan but also accelerated weight loss for many participants.

Cravings, unlike hunger, are typically tied to specific foods, like that slice of chocolate cake or a favourite fast food item, and can be emotionally driven. Denying these urges completely often leads to frustration, which may cause diet fatigue or binge eating. The study's approach suggests moderation, not elimination, could be the smarter path.

The role of stress in sabotaging progress

For those who still found cravings hard to manage even after following weight loss routines, the researchers pointed to another key player: stress. Chronic stress, they noted, can intensify food cravings and undermine progress. To address this, the authors recommend incorporating stress-reduction practices, such as mindfulness or anxiety coping strategies, into weight loss programs.
