10 Reasons Why You Gain Weight Although You Eat Healthily

Some reasons for weight gain have nothing to do with food habits.

Those of you trying to lose weight or combat obesity know how tough it gets. And sometimes, no matter how well you regulate your diet, your body just doesn’t lose those pounds. This happens to your body when you experience certain health issues, making you gain weight in a jiffy. Here are some reasons that have nothing to do with food that can be the possible force behind that stubborn fat in your body.

1. Excess Stress

Excess stress produces excess cortisol, which makes you gain more weight.


According to the American Psychological Association, stress is one of the foremost reasons for health crises such as obesity and depression. When stressed out, your body releases an excess of the stress hormone (cortisol), which causes severe hormonal imbalances. The formula here is simple: Excess stress produces excess cortisol, which increases weight gain.

You start stress eating and emotional eating, resulting in fat deposits in the waist and abdomen, comparatively fuller face and neck than the arms and legs, high blood sugar and blood pressure, extreme mood swings, and muscle fatigue. Your best bet out of this is to exercise regularly, get good sleep, meditate to improve your stress response, and learn to control your breath.


2. Age-Related Changes

The process of aging causes lowered metabolism and consequent weight gain.

This is an issue you cannot ignore, with painful joints, fatigue, graying hair, and wrinkles along with the inevitable weight gain. This is because, along with your immunity, your metabolism also goes down south. Although you might have improved your food habits over the years, the binge eating and late night snacks will catch up on you.


Along with lowered metabolism and fat gain, you start to lose your muscle mass as well, which otherwise help burn calories. With aging, more than controlling your diet, you need to exercise regularly as much as possible. Reduce carbs in your diet and go for low-fat proteins.

3. Prescription Medicines

One of the side effects of taking certain prescription medicines is weight gain.


Almost all medicines have at least one minor side effect. For many prescription medicines, one of these is weight gain. Gaining abnormal, stubborn weight is commonly seen in people who take antidepressants; antipsychotics; anti-seizure pills; meds for blood pressure, heart rate regulation, and diabetes; birth control pills; and even hormone therapy.

Talk to your doctor whenever you’re prescribed medications. Follow a suitable, healthy lifestyle to counteract the side effects or find an alternative medicine.


4. Inadequate Sleep

Sleeping for shorter hours makes you impulsive, eat more, and gain weight with an unhealthy lifestyle.

Some people are perfectly fine and energetic with 6 hours or sleep and some need up to 8 hours. No matter how many hours you need, getting adequate sleep is a prerequisite for a healthy life. Don’t believe it? Observe your weight if you have been sleeping less for a longer term.


A lack of sleep makes your body as fatigued as an aging body. You’re cranky, extremely hungry, and rarely under control. You’re also more likely to load up on junk and late-night snacks with less sleep. Inadvertently, you’re bound to gain excess weight. So along with getting enough sleep, ensure the sleep quality is also good. Consult your doctor if you’re not able to manage either.

5. Liver Problems

Liver problems can cause weight gain and vice versa.


While excess weight and obesity can actually lead to liver problems, some people also experience weight gain due to an unhealthy liver. So this is just one possible reason for your randomly accumulated weight and only a doctor can decide for you. The symptoms of this might include excess blood pressure, cholesterol, blood sugar, allergies, and joint pain.

6. Hypothyroidism

Hypothyroidism causes weight gain with reduced metabolism.

Hypothyroidism, or an underactive thyroid, means that the thyroid gland is working slow and producing fewer than required thyroid hormones. This condition is more common in older women, affects your metabolism, and leads to definite weight gain. Along with excess weight, hypothyroidism will also cause constipation, fatigue, hair loss, reduced heartbeat, depression, and a puffy face.

7. Hormonal Changes

Hormonal imbalance leads to mood swings, sweet craving, and consequent fat gain.

Some common issues in women, such as polycystic ovarian syndrome, perimenopause, and menopause, and andropause in men all cause a shift in hormonal balance. This imbalance will make it difficult for you to lose weight and cause weight gain even if you eat healthily and exercise every day. In such situations, you will also experience symptoms such as sweet craving, pain in the ovaries in women, and fat gain in the lower body.

Among these, women should note PCOS as the most troublesome as it causes various other issues such as irregular periods, infertility, and excess facial hair along with weight gain.

8. Hereditary Weight Gain

In some cases, you need no reason but the wrong gene to gain weight.

With some, weight gain is their own fault. But with some rare cases, it’s just hereditary. No matter how much you diet and exercise, your predisposition to obesity with a family history gets in your way. Your only way out is to figure out a weight-loss regime that can beat your gene mutation.

9. Cushing’s Syndrome

Cushing's syndrome is rare but can cause high levels of cortisol, causing weight gain.

This is a syndrome that is quite rare, affecting just about 1 in 50k people. But if you’re the unlucky one, your cortisol levels will be extremely high. Cushing’s syndrome can be due to a steroid treatment or due to a tumor. Whatever the cause, it’ll make you gain weight. In this case, you’ll notice excess fat deposition on the upper part of your body including face, stomach, and chest.

10. Fluid Retention

Standing for a long duration or going through the pre-menstrual phase can cause fluid retention in parts of the body.

This an extremely common cause of weight gain, wherein your body gets swollen up with fluid accumulation. You’ll experience this if you need to stand for a long duration or if when you’re pre-menstrual. The fluid usually settles in any one part of the body, such as ankles. Extreme cases of fluid retention can make you feel breathless and can also indicate kidney or heart issues.
