At RX Direct, we often speak to patients who are frustrated with their weight loss progress. They ask the same question time and again: why am I not losing weight despite my efforts? In many cases, the answer lies in common misconceptions about how the body works and what it truly takes to see results. These myths can lead to habits that slow down progress, even when you feel like you are doing everything right. Here, we uncover five of the most common myths and the truths that can help get your journey back on track.
Myth 1: Eating less is always better
Many people believe that drastically reducing calories will lead to faster weight loss. While eating fewer calories than you burn is important for weight loss, going too low can have the opposite effect. Severely restricting calories can slow your metabolism, making it harder for your body to burn fat. It can also lead to fatigue, nutrient deficiencies, and increased cravings, which can cause you to overeat later.
The truth is that a moderate calorie deficit is more effective and sustainable. By eating enough to fuel your daily activities while still creating a calorie shortfall, you can lose weight steadily without compromising your health. Focusing on nutrient-rich foods such as lean proteins, whole grains, fruits, and vegetables will help you feel satisfied while supporting your metabolism.

Myth 2: You must cut all carbs
Carbohydrates are often blamed for weight gain, and many people try to remove them completely from their diet. While cutting back on refined carbs like white bread, sugary snacks, and pastries can support weight loss, eliminating all carbs is unnecessary and can even be harmful.
The truth is that healthy carbohydrates such as oats, quinoa, sweet potatoes, and wholemeal bread provide essential nutrients and energy. They help fuel workouts, support brain function, and keep your digestive system healthy. Completely removing carbs can lead to low energy, poor concentration, and difficulty sticking to your eating plan long term. Instead of cutting them out entirely, focus on choosing high-quality carbs in sensible portions.
Myth 3: Exercise alone is enough to lose weight
Some people believe that as long as they exercise regularly, they can eat whatever they want and still lose weight. While exercise is an important part of a healthy lifestyle, it is not a substitute for balanced eating. It is possible to burn hundreds of calories in a workout but consume the same amount or more in just a few minutes of eating high-calorie foods.
The truth is that weight loss requires a combination of physical activity and healthy eating habits. Exercise supports weight loss by increasing calorie burn, preserving muscle mass, and improving mood, but nutrition plays a bigger role in creating the calorie deficit needed for fat loss. To see the best results, combine regular exercise with a balanced, portion-controlled diet.
Myth 4: Weight loss should be constant every week
When people step on the scales and see no change, they often think they are failing. This belief can cause frustration and lead to giving up too soon. In reality, weight loss is rarely a straight line. It is normal for weight to fluctuate due to factors such as water retention, hormonal changes, and muscle gain from exercise.
The truth is that focusing only on the scales can be misleading. Non-scale victories like looser clothes, improved energy, and better fitness levels are just as important indicators of progress. Instead of expecting the same loss each week, look at trends over time. A consistent downward pattern over several weeks or months is a sign that your approach is working, even if some weeks show little or no change.

Myth 5: You have to follow a strict diet to succeed
Many people believe that sticking to a highly restrictive diet is the only way to lose weight. While this can produce short-term results, it often leads to burnout and eventual weight regain. Strict diets are hard to maintain, especially when they cut out entire food groups or require complicated meal rules.
The truth is that the most successful weight loss plans are flexible and sustainable. Rather than focusing on rigid rules, aim for balanced meals you enjoy and can maintain in the long run. This approach makes it easier to stick with your plan, avoid feelings of deprivation, and build healthy habits that last. At RX Direct, we encourage gradual changes that fit into your lifestyle, so you can achieve lasting results without feeling restricted.
How these myths can slow progress
Believing these myths can lead to habits that undermine your efforts, even if your intentions are good. Severely restricting calories, cutting out whole food groups, relying only on exercise, expecting constant results, or following overly strict diets can all lead to frustration, low motivation, and eventual weight regain.
The most effective weight loss plans address both nutrition and lifestyle in a way that is realistic for the long term. They allow for flexibility, focus on health rather than perfection, and encourage a steady approach rather than quick fixes.
Make Your Goals a Reality
If you have been asking yourself, “Why am I not losing weight?”, it may be worth examining whether these myths are influencing your habits.
If traditional methods like diet changes and regular exercise have not delivered the results you hoped for, weight loss medications could be a helpful next step. These treatments, such as Mounjaro or Wegovy, work by targeting appetite control and supporting your body’s natural ability to manage weight, making it easier to stick to healthy habits. They are not a replacement for lifestyle changes, but when prescribed as part of a comprehensive plan, they can provide the boost you need to break through a plateau and start seeing progress. At RX Direct, we assess each patient individually to ensure any medication is safe, appropriate, and combined with ongoing guidance for long-term success.
At RX Direct, we believe in a personalised approach that combines balanced nutrition, regular activity, and medical support. By replacing these misconceptions with proven strategies, you can make steady progress towards your goals and maintain your results for the long term.
