You might be focusing on your diet and exercise, but many hidden factors could be working against your body's natural ability to burn calories efficiently.
When it comes to metabolism, some seemingly harmless habits can slow down your metabolism, leading to weight gain, fatigue, and difficulty losing weight. Here are some uncommon yet significant factors that may be causing you to gain weight:

1. Frequent Use of Scented Candles and Air Fresheners
Many scented candles and air fresheners contain chemicals known as endocrine disruptors, particularly phthalates and parabens. These chemicals interfere with hormone production, including thyroid function, which plays a major role in regulating metabolism.
Some artificial fragrances contain toxins that can disrupt fat metabolism, making it harder for your body to burn calories efficiently. Exposure to these toxins over time can increase fat storage, particularly around the abdomen.
2. Using Non-Stick Cookware Too Often
Non-stick cookware is often coated with perfluorinated compounds (PFCs), which have been linked to thyroid dysfunction and weight gain. PFCs interfere with thyroid hormones, which control how your body burns calories and uses energy.
Some studies suggest that exposure to PFCs can lead to insulin resistance, making it harder for your body to regulate blood sugar and burn fat efficiently. You can switch to stainless steel, cast iron, or ceramic cookware. If using non-stick cookware, avoid overheating it, as high temperatures release more harmful chemicals.
3. Not Chewing Food Properly
Eating too quickly or not chewing food thoroughly can put a strain on your digestive system and slow down your metabolism. Digestion begins in the mouth, where enzymes start breaking down food. If you don't chew enough, your body has to work harder to digest it.
Poor digestion leads to nutrient malabsorption, meaning your body gets less energy from food, causing metabolic inefficiencies. Studies show that chewing food thoroughly can increase calorie burn and improve digestion. Aim to chew each bite 20–30 times before swallowing. Eat slowly and avoid distractions while eating to focus on chewing properly.
4. Posture
Your posture does more than just affect how you look, it also influences your metabolism and caloric burn throughout the day. Slouching reduces oxygen intake and slows digestion, which can decrease metabolic rate. Poor posture compresses abdominal organs, making digestion less efficient and leading to bloating and weight retention.
Standing or sitting with good posture activates core muscles, helping to burn more calories throughout the day. Sit up straight and engage your core muscles while working or walking. Stretch frequently to improve spinal alignment and circulation.

5. Breathing Shallowly
Many people breathe too shallowly, especially when stressed, without realiisng that deep breathing can boost metabolism. Shallow breathing reduces oxygen intake, which means less oxygen is available to burn fat efficiently. Deep breathing lowers stress hormone levels, particularly cortisol, which is linked to abdominal fat storage.
Oxygen is essential for cellular energy production. When levels are low, metabolism slows down. Practise deep belly breathing. Inhale through your nose, expand your diaphragm, and exhale slowly. Try mindfulness exercises like yoga or meditation to improve breathing patterns.
6. Eating While Lying Down
It may seem harmless, but eating while lying down can slow digestion and negatively impact your metabolism. Lying down while eating reduces digestive efficiency, making food take longer to break down. It can increase acid reflux, causing discomfort and making digestion even slower.
Sitting upright helps food move efficiently through the digestive tract, preventing bloating and metabolic sluggishness. After meals, take a short walk or stay upright for at least 30 minutes before lying down.
7. Eating the Same Foods Every Day for a Long Time
Sticking to a limited diet may seem like a safe choice, but it can actually slow down metabolism by depriving your body of essential nutrients. A lack of dietary variety can lead to nutrient deficiencies, which can slow down metabolic processes.
Your body adapts to the same foods, potentially leading to a reduced thermic effect of food (TEF) meaning your body burns fewer calories digesting the same meals over time. Rotate your meals and include a variety of proteins, healthy fats, and fibre-rich carbs. Incorporate different spices and herbs, which can also boost metabolism naturally.
8. Using Too Many Skincare Products with Toxins
Many skincare and cosmetic products contain harmful chemicals like parabens, phthalates, and triclosan, which interfere with hormone function and slow metabolism. These toxins can disrupt the endocrine system, affecting metabolism-regulating hormones like thyroid hormones and insulin.
Some chemicals in skincare products have been linked to increased fat storage and weight gain. Read ingredient labels and avoid products with harmful additives.
9. Overdrinking Coffee
While coffee can boost metabolism in moderation, too much caffeine can have the opposite effect. Excess caffeine can increase cortisol levels, which slows down fat metabolism and promotes fat storage. Too much coffee can lead to dehydration, making digestion and nutrient absorption less efficient.
Dependency on caffeine can reduce the body’s natural energy-burning processes. Limit coffee intake to 1–2 cups per day. Stay hydrated with water and herbal teas to support metabolic function.
