Why would a spouse encourage their partner to gain weight? The answer might seem counterintuitive at first—after all, we often hear about couples supporting each other to get healthier or maintain their figures. Yet, the dynamics of relationships, emotional security, and shared habits can lead not only to unintentional weight gain but sometimes to subtle or even explicit encouragement of it. Understanding the reasons behind this phenomenon requires looking at relationship psychology, social habits, and individual motivations. Let’s dig into the complex reality behind why some spouses might actually foster or even promote weight gain in their partners.
Short answer: A spouse may encourage weight gain in their partner—directly or indirectly—for reasons ranging from shared comfort and emotional security, to mutual indulgence in food-focused bonding, to subconscious desires to reinforce relationship stability or reduce perceived competition. Sometimes, this encouragement is not deliberate but emerges from shared routines, emotional reassurance, or a desire to avoid conflict about body image. In rarer cases, there may be deeper psychological or relational motives at play.
The Comfort of Togetherness
One of the most common drivers of weight gain among couples is the simple shift in priorities that comes with a committed relationship. According to Henry Ford Health (henryford.com), research shows that “many happy couples tend to gain weight” soon after entering a relationship, with the trend often continuing into the years of commitment. This isn’t necessarily because one partner is actively encouraging the other to gain weight, but rather because both are swept up in the comfort of togetherness. Dates often revolve around “trying new restaurants or bars together rather than cooking healthy foods at home,” and couples may “prioritize spending time with your partner over going to the gym.” These changes in routine—more frequent eating out, larger portions, richer foods, and less physical activity—are classic ingredients for gradual weight gain.
The mirror.co.uk article echoes this, noting that “happy relationships influence weight gain over any other life experience including giving up smoking or having a child.” The explanation is straightforward: when people feel secure and loved, the pressure to maintain a certain appearance for the sake of attracting a partner diminishes. As one relationship expert quoted by mirror.co.uk points out, “If their partner is constantly reinforcing encouragement they won’t think twice about putting on a few extra pounds.” This “constant reinforcement” can take the form of compliments, indifference to weight changes, or shared enjoyment of indulgent meals.
Emotional Security and Unconditional Love
Emotional security is a powerful motivator in any relationship. When a partner expresses or demonstrates unconditional love—saying things like “I worship you whether you’re a size 10 or 14,” as one woman related in mirror.co.uk—the other partner may feel less pressure to regulate their eating or exercise habits. This isn’t so much encouragement to gain weight as it is a removal of barriers to doing so. Relationship expert Dominic Knight, also cited in mirror.co.uk, explains that when someone feels “I’ve got this person now I don’t have to try,” it can lead to relaxing previous self-imposed restrictions. This sense of safety can be comforting, but it may also subtly foster a more indulgent lifestyle.
Henry Ford Health points out that couples often become “less concerned about your appearance” as the relationship matures. The need to impress fades, and with it, the discipline that may have kept weight in check during the early dating phase. This mutual relaxation can create an environment where weight gain is not only tolerated but passively supported—especially if both partners are enjoying the new routines together.
Bonding Over Food and Shared Habits
Food is a universal bonding tool, and couples frequently use shared meals to reinforce their connection. The story of Jess and Rob in mirror.co.uk illustrates this: their relationship involved “cosy takeaways in, going to the pub and eating out,” with Rob’s skills as a chef making their time together particularly delicious. Jess’s gradual weight gain was a side effect of the lifestyle they built together, not a deliberate choice. Yet, by participating in these activities and reinforcing each other’s habits, both partners contributed to the trend.
Henry Ford Health emphasizes that “changing your eating habits to fit your partner’s” is common. A person might start skipping breakfast or eating less healthily simply to align with their partner’s preferences. Over time, the couple’s mutual choices can create a self-reinforcing cycle of indulgence, especially if neither is motivated to break the routine. This kind of encouragement is subtle but powerful, rooted in the pleasure and intimacy of shared experiences.
The Desire to Avoid Body Image Conflict
Discussing weight can be fraught with emotional risk, especially in a society where body image is a sensitive topic. As wikihow.com points out, “most people who are over or underweight are very aware of this fact,” and often don’t need to be reminded. Many spouses, consciously or not, avoid raising concerns about weight changes to protect their partner’s self-esteem or to sidestep arguments. This avoidance can become a form of implicit encouragement, signaling that weight gain is either unnoticed or unimportant within the relationship.
Henry Ford Health advises that “encourage healthy eating habits without policing each other’s food choices” is a more supportive approach. Yet, when neither partner wants to risk upsetting the other, they may both drift into less healthy routines. The reluctance to address weight gain directly can, paradoxically, support its continuation.
Reinforcing Relationship Stability and Reducing Competition
In some cases, a spouse might subconsciously—or rarely, even consciously—encourage weight gain as a way to reinforce relationship stability or reduce perceived threats from outside attention. While this motive is less common and more complex, it has been discussed in relationship psychology circles. The idea is that if a partner gains weight, they may be perceived as less likely to attract outside romantic interest, thereby reducing the risk of infidelity or competition. While none of the provided sources promote this as a healthy or ethical strategy, the underlying psychology can sometimes influence behavior in subtle ways.
The forums.studentdoctor.net discussion hints at this dynamic, noting that partners should “strive to be as healthy as you can for each other,” but also that “not saying something and enabling someone’s weight to increase...is about one of the worst health things that could happen to them physically.” This suggests that some spouses may avoid addressing weight gain for fear of conflict, but others might feel ambivalent if it means more relationship security—especially if appearance-based competition is a source of anxiety.
Shared Life Stressors and Coping Mechanisms
Relationships are not lived in a vacuum, and external stressors—like demanding jobs, family pressures, or health issues—can drive couples to seek comfort in food or sedentary activities. Henry Ford Health observes that “drinking more alcohol” and “spending less time exercising” are common ways couples cope with the demands of daily life. These behaviors, when shared, can become normalized and even encouraged as mutual coping mechanisms.
In the forums.studentdoctor.net thread, participants discuss how “problematic and shared habits” can lead to weight gain, and how one might “start by identifying if there’s any problematic and shared habits that could be addressed first.” When both partners are under stress, they may reinforce each other’s unhealthy behaviors as forms of support or solidarity, even if the long-term effects are detrimental.
The Role of Gender and Social Expectations
Gender dynamics can also play a role in how weight gain is approached within a relationship. The discussion in forums.studentdoctor.net points out that “Women rarely need to be told they’re fat and their partner may not find them attractive,” while men may be less attuned to subtle comments or changes. Social expectations around attractiveness and body image can shape whether or not a partner feels justified—or obligated—to encourage or discourage weight gain.
On the flip side, some spouses may encourage weight gain as a way to challenge societal pressures or to signal that their love is unconditional, regardless of body size. The case of Rob in mirror.co.uk, who “never commented on whether I’d gained or lost, he worships me whether I’m a size 10 or 14,” exemplifies this attitude. This approach can help foster self-acceptance and reduce anxiety about appearance, but as Jess herself noted, it can also lead to complacency if not balanced with attention to health and well-being.
When Encouragement Crosses a Line
It’s important to distinguish between passive encouragement—like sharing indulgent meals or avoiding tough conversations—and active encouragement, which might involve one partner consistently offering second helpings, dismissing health concerns, or even pressuring the other to eat more. While the sources reviewed here focus primarily on the former, active encouragement can sometimes reflect deeper issues, such as control, insecurity, or even sabotage. The forums.studentdoctor.net thread warns that “enabling someone’s weight to increase...is about one of the worst health things that could happen to them,” underscoring the potential harm of unchecked encouragement.
Healthy Approaches: Support Versus Enablement
Most experts agree that the healthiest relationships strike a balance between accepting each other’s bodies and supporting one another’s well-being. Henry Ford Health recommends that couples “share your health goals with your partner and discuss how you can support each other as you work toward wellness.” Similarly, wikihow.com suggests making “love and health the centerpieces of the conversation” when discussing weight, and emphasizes that any encouragement should be rooted in genuine concern for a partner’s happiness and longevity, not personal insecurity or control.
The central lesson from all these sources is that encouragement—whether to gain or lose weight—should focus on mutual health, happiness, and respect. Unconditional love is vital, but so is honest communication and shared responsibility for making choices that support both partners’ long-term well-being.
In conclusion, a spouse might encourage weight gain in their partner for reasons as varied as shared comfort, emotional security, lifestyle habits, avoidance of conflict, or deeper psychological dynamics. “It’s easy to become relaxed, where trips to the gym can easily be swapped for takeaways on the sofa and indulgent meals out,” as mirror.co.uk puts it. While this can be a sign of a loving and secure relationship, couples should remain mindful of the health implications and strive to support each other in ways that foster both emotional closeness and physical well-being. As Henry Ford Health reminds us, couples can “strengthen their bond by making their health a priority”—together.
