You’ve been skimping on your food intake. You’ve given up on desserts, counted your calories, started regularly exercising and are trying to be consistent. However, every time you step on the scale, it’s only a slight increase. If you’ve asked yourself the question, “Why am I not losing weight in a calorie deficit?,” then you’re not alone. It is one of the most asked problems of the people while they are on a weight loss program. Keeping a calorie deficit is crucial to weight loss, but it’s not all there is to it. Your metabolism, hormones, sleep patterns, stress, medication, and health issues all impact the way that your body utilizes and stores energy. If your weight has not changed despite consistent effort, one or more of these hidden factors may be responsible. 1. You May Not Actually Be in a Calorie Deficit The first is you are not necessarily in a calorie deficit. Even the most disciplined can be off target for calorie consumption. Little extras like cooking oil, salad dressings, sugary drinks, coffee creamers, or frequent “good-for-you” snacks can add quickly. Calories on the weekends may also compensate for the calorie deficit that occurs throughout the week. But before automatically jumping to the conclusion that something is amiss, portion sizes should be looked at and the meals should be accurately recorded. 2. Your Metabolism Has Adapted When you keep the calories down for an extended amount of time, the body will, naturally, conserve energy. The term adaptive thermogenesis (your body’s way of slowing metabolism when you’re trying to lose weight) describes this effect, which decreases the amount of calories burned day-to-day. That’s one of the reasons for weight-loss plateaus during crash diets. 3. You are losing fat, but gaining muscle. For those who have just begun to strength train, it may not be so simple as the scale reading. You may not lose weight, but you may be able to reduce your waist size and increase your body fat percentage as your muscles gain lean mass and your body fat reduces. Progress photos and body measurements can be a more accurate reflection than a weighing scale. 4.  Insulin Resistance Is Affecting Fat Loss One of the most prevalent metabolic problems that makes it hard to lose weight is insulin resistance, or a situation where the cells don’t react well to insulin. The body responds to the glucose by creating insulin which promotes fat storage and reduces utilization of fat for energy. Signs may include: Gaining weight in the belly area Constant hunger Sugar cravings Fatigue after meals Pre diabetes 5. Your thyroid may be slowing your metabolism down. If the thyroid is under active, or hypothyroid, then many activities in the body are slowed down, including the metabolism. Some of the other symptoms of thyroid disorders include thinning hair, sensitivity to colds, constipation, dry skin, and unexplained weight gain. 6. PCOS(PMOS) Makes Weight Loss More Difficult Polycystic Ovary Syndrome (PCOS) is now referred to as PMOS (Poly endocrine Metabolic Ovarian Syndrome) and for many women is a condition that has an impact on more than just their reproductive health. Insulin resistance and hormonal imbalance are often linked with PCOS, making it hard to shed pounds with good eating habits. Some of the most frequent signs are irregular periods, acne, an excess of facial hair growth, and weight retention in the abdomen. 7. Bad sleep is on your side Sleep is a big factor that is not considered when it involves weight management. Regularly having less than 7 hours of sleep wreaks havoc on hormones that control hunger and fullness. Consequently, you might feel more hungry, have a greater appetite, feel less energetic, and have slower metabolic activity. Enhanced sleep quality can help promote healthier eating patterns and metabolic health. 8. Chronic Stress Raises Cortisol Levels A prolonged stress can raise cortisol, which is also known as the stress hormone. Chronic elevated cortisol levels can promote fat in the belly and can make one more tempted to eat high calorie comfort foods. When paired with poor sleep, stress can work its magic without you realizing it’s hindering your weight loss. 9. Some Drugs Affect Weight Weight gain or slower weight loss may be contributed by some prescription drugs. Some antidepressants, steroids, diabetes drugs and some hormone treatments. Do not discontinue medications prescribed by health care providers. 10. Hormonal changes during menopause As with most other hormonal changes that occur during menopause, loss of estrogen may cause a change in body composition, decrease muscle mass, and redistribute fat to the abdomen. A lot of women find that the tactics that have been effective for them in their 30s cannot be duplicated in their 40s. 11. Fatty Liver Disease May Affect Metabolic Health Non-alcoholic fatty liver disease (NAFLD) closely associates with obesity, insulin resistance and metabolic disorder. If liver function is impaired, controlling body weight is even more challenging, and it is particularly important to assess liver health. 12. Water Retention Can Mask Fat Loss Occasionally, the scale is measuring water weight instead of fat. Fluctuations in hormones, stress, too much sodium in the diet, or some prescriptions may cause a temporary increase in fluid retention that can give the false appearance of weight loss stalls. 13. Not getting sufficient protein. Protein helps to maintain muscle and promotes fullness. If you lose weight without the right protein, your body could be stripping your body of muscle mass and this can cause your metabolism to decrease slowly. 14. You’re moving less than you think However, there are many people who, when they begin to trim the fat, end up being less active than they were previously. This decrease in calories expended on non-exercise activity thermogenesis (NEAT) – the calories burned in normal daily activities like walking, standing, and housework can have a significant impact on total daily energy expenditure. 15. An underlying metabolic condition is not being identified. At times the scale may be more indicative of a medical instead of
