A million-dollar question, yet a mystery to most. Why women get fat after marriage is probably on every woman’s mind.
However, as a newly married woman, this is a valid question and there’s absolutely nothing to be ashamed of. It is very normal to gain a little weight after getting married. Many people also say that it is a healthy sign or a sign of a secure relationship.
Research shows, people in a happy relationship experience gradual weight gain because of emotional security and relaxed routines.
Marriage, the beginning of a beautiful new phase of a woman’s life, is full of new routines, emotional fulfilment and socialising with new people. A noticeable physical change in the body, like belly fat after marriage, leads women to doubt themselves with one question: “Why do females gain weight after marriage?” Let’s answer that!
Why Your Weighing Scale Might Be Going Up
There are various answers to the question,’why women gain weight after marriage’, some of the common reasons or the answers to this question are:

Change in Daily Habits
After marriage, your daily routine tends to change. First comes the honeymoon, lots of indulgence without the guilt to celebrate your life ahead, which is great! But then daily habits also begin to change. Shared meals lead to larger portion sizes, and regular social events (even birthday celebrations of kids in the family now), increase the consumption of junk food.
As you adopt the habits of your partner, your sleeping cycle is affected. With marriage also comes an increase in responsibilities, which means that married women get less time to focus on themselves and their bodies. These lifestyle changes result in female body changes after marriage.
Not Eating Mindfully
Food habits tend to change significantly after marriage, resulting in physical changes in the female body after marriage. Since most meals are not eaten together, women adjust to the food preferences of their partner or their family. Tasty bites turn into increased junk food intake. If one person is working late, the other also delays their meal. Late-night dinners or erratic meal timings could also be the reason for post-marriage weight gain.
Hormonal Factors in Females
Another reason for weight gain after marriage is a change in hormones. There are changes in estrogen and progesterone levels due to lifestyle changes and new physical intimacy. There are also cortisol spikes when the stress of wedding planning or new responsibilities might catch up, which is one of the main reasons behind belly fat after marriage. When it comes to these adjustments, the regulation of body weight is affected.
The increased fat storage mainly happens around the hips and thighs, and also makes women feel bloated. Nutritional changes or disrupted sleep affect women’s thyroid health, due to which metabolism slows down. The reason why women gain weight after marriage cannot be pinpointed to any one of these factors, but these hormonal changes interact with other habits to trigger weight gain.
Comfort Eating
A sense of emotional safety, companionship and stability comes along with marriage. Women’s eating habits change unintentionally because they get more relaxed with how they appear. Pre-marriage, most women jump on the treadmill in preparation, and there is always pressure to look a certain way. However, the enjoyment of comfort foods together increases calories without being noticed.
Hunger hormones, ghrelin and leptin, which regulate appetite, are affected when emotional stress is high. And sometimes emotional needs are met through tasty meals, leading to long-term weight gain.
Personal Fitness
Before marriage, women tend to make more time for personal fitness by staying active. But slowly, personal fitness finds itself on the lower end of daily tasks, and the question comes up, ‘Why do women gain weight after marriage?’ Household responsibilities, social commitments and work, balancing all three can be difficult and physically draining.
At the end of the day, women have little energy or mental space to accommodate regular exercise. Metabolism slows down, and muscle mass is affected; this loss of “me time” leads to weight gain over time. If physical wellness and activity, even a simple walk, are incorporated into women’s daily routine, then weight gain after marriage can be slowed down.
Pregnancy Planning
What follows after marriage are the discussions of children, at least for most women. Pregnancy and motherhood are one of the main factors behind the marriage-weight connection. During pregnancy, a natural weight gain supports the baby’s development. Although healthy, this extra weight means more fat storage for women.
Post childbirth, postpartum hormonal shifts slow down metabolism, increase appetite and encourage fat retention. While the body heals post-pregnancy, there is reduced mobility and disruption in sleeping patterns. These changes are a normal part of the female life cycle and can lead to physical changes in the female body after marriage.
