Men reject traditional diets as restrictive, female-focused: study

In England, seven out of every ten men are either overweight or living with obesity—a proportion that outpaces women, where the figure sits at sixty-two percent. Yet the weight-loss industry has largely overlooked them. A new study from Anglia Ruskin University, published in PLOS One, offers an explanation: men are rejecting the diet programs available to them, not because they lack motivation, but because those programs feel designed for someone else entirely.

Researchers interviewed twenty-four men over thirty who had experience with weight gain and either had tried a weight-loss program or were considering one. What emerged from those conversations was a consistent pattern of resistance rooted in how dieting itself is framed and marketed. The men spoke of diet as a word that conjures only deprivation. One participant put it plainly: the moment you say diet, people think restriction, restriction, restriction. They associated weight-loss programs with denial of the foods they actually wanted to eat, and they were unwilling to sign up for what felt like sustained sacrifice.

But there was another barrier, one that cut deeper into how men saw themselves. Across every focus group, dieting registered as fundamentally feminine. The conversations about weight loss, the men said, happen in magazines and on social media—spaces coded as female. It was not a topic men discussed with each other. Several participants admitted they would feel self-conscious, even embarrassed, to be seen engaging in dieting themselves. The perception that weight-loss programs were built for women, by women, made them feel like outsiders in their own health.

The study found that men were far more likely to dismiss a program if it seemed female-oriented or overly restrictive. But the same men perked up when the framing changed. They responded to weight loss when it was presented as a competitive challenge, as something to tackle alongside a partner. The difference was not subtle. One man described how his wife's support made all the difference—without it, he said, he would not have stuck with it. Many of the participants revealed that their dietary changes had actually been orchestrated by their partners, whom they trusted to know more about nutrition and dieting than they did themselves.

Justin Roberts, a professor of nutritional physiology at Anglia Ruskin and one of the study's lead authors, distilled the findings into practical guidance for public health. Weight-loss programs aimed at men should emphasize quick wins and early rewards. They should frame the effort as a personal challenge rather than a diet. They could incorporate sport or physical activity—strength training, endurance challenges—things that appeal to how men think about their bodies. The language matters: avoid the word diet altogether. And couples-based initiatives, the research suggests, could be particularly powerful. A buddy system or mentor relationship also showed promise.

Roberts acknowledged the study's limits. Twenty-four men, all in England, all in heterosexual relationships—the sample was small and narrow. Future research involving larger, more diverse groups, including men in same-sex partnerships, could reveal whether these patterns hold across different communities and relationship structures. But the core finding stands: the public health system has built weight-loss support around one set of assumptions and one audience, and in doing so, has largely failed to reach the men who need it most.
