If you canâ€™t fit into the same pair of jeans you wore on your first date with your partner, thereâ€™s a legitimate reason why: Love makes you gain weight.
A couple on Twitter recently illustrated this phenomenon with a series of photos featuring them at varying weights from the beginning of their relationship to present day.
â€œ120 to 160 & 170 to 200,â€ Twitter user @kaaalei captioned the July 1st photos, which show the couple â€” who look amazing â€” appearing leaner before progressing to fitter, muscular forms.

Research conducted by Southern Methodist University in Dallas, Texas found that husbands and wives who are satisfied with their marriages gained weight over a period of four years, compared to those in unhappy relationships who didnâ€™t gain weight. One possible reason: People who believed they had found their true love were more comfortable with their bodies than they were when trying to first attract a mate.
â€œWhen you first fall in love, the brain is flooded with dopamine, a stimulating chemical that suppresses the appetite,â€ Helen Fisher, PhD., a biological anthropologist at Rutgers University, tells Yahoo Beauty. â€œWhen people experience a rush of dopamine, they canâ€™t sleep at night because theyâ€™re thinking about the other person, they fixate over whether that person will text them back, and they feel optimistic and sexually possessive.â€ One study even found that being in love activates the same portion of the brain associated with addiction, which helps explain why you feel obsessed with the object of your desire.
According to Fisher, people can experience this blissful â€œbrain systemâ€ called romantic love, for anywhere from one to five years. â€œWeâ€™ve even scanned the brains of couples married for 25 years who swore they were still madly in love,â€ says Fisher. â€œFor example, if youâ€™ve been with your partner for many years but only see them periodically, itâ€™s possible to still feel passionately in love,â€ she adds.
The next is called attachment, during which people fixate solely on their partners. â€œThereâ€™s a sense of calm and comfort and itâ€™s common to feel at times as though you both love and hate that person,â€ says Fisher. And hereâ€™s where weight gain often occurs: If youâ€™re spending lots of time together, youâ€™re likely cooking and eating the same meals, and feeling more confident in your feelings for each other. As a result, you may ease up on the fitness and health habits you worked hard to maintain at the beginning of your relationship.
From an evolutionary perspective, feeling bonded to one mate allowed couples to successfully raise their offspring after their lustful feelings died down. And if youâ€™ve gotten this far in a relationship, unhealthy habits will be even harder to break.
â€œHowever, itâ€™s important to note that not all couples experience the brain systems in one particular order,â€ says Fisher. â€œRelationships can begin at any stage and fluctuate depending on variety of factors. In a good relationship, you want to keep all systems alive.â€
Of course, this doesnâ€™t mean that long-term couples canâ€™t stay fit. Not only will hitting the gym together keep you healthy, physical exercise is scientifically proven to boost your sex drive. #Relationshipgoals.
