A Dietitian Busting 10 Common Diet Myths: What You Really Need to Know About Losing Weight

Updated: Nov 10, 2023

In the quest for weight loss and improved health, we often find ourselves bombarded with countless diet tips and tricks. However, not all of this advice is accurate or based on scientific evidence.

In this article, our Chief French Dietitian is going to separate fact from fiction by debunking 10 common diet myths and shedding light on what you truly need to know about achieving your weight loss goals.

Myth 1: Skipping Meals Leads to Weight Loss

Reality: Skipping meals may seem like a shortcut to cutting calories, but it can backfire. When you skip meals, you're more likely to overeat later in the day due to increased hunger. Additionally, it can slow down your metabolism, making it harder to burn calories efficiently. Instead, focus on balanced, regular meals and snacks to maintain steady energy levels and prevent overindulging.

Myth 2: Carbohydrates Make You Gain Weight

Reality: Carbohydrates are an essential part of a balanced diet. It's the type and quantity of carbs that matter. Whole grains, fruits, and vegetables are packed with nutrients and fiber, while refined carbs like sugary snacks and white bread can contribute to weight gain when consumed in excess. Aim for complex carbohydrates and monitor portion sizes.

Myth 3: Fat-Free Is Always Healthier

Reality: Not all fats are created equal. While it's true that excessive saturated and trans fats can be harmful, healthy fats like those found in avocados, nuts, and olive oil are essential for overall health. Fat-free products often compensate with added sugars and artificial ingredients, which can be detrimental to your health and weight management. Opt for a balanced approach and incorporate good fats in moderation.

Myth 4: Detox Diets Cleanse Your System

Reality: Detox diets and cleanses are popular, but they're not an effective long-term solution for weight loss. Your body already has a built-in detox system (your liver and kidneys), and extreme detox diets can deprive you of essential nutrients and lead to muscle loss. Focus on a balanced, whole-foods-based diet to support your body's natural detoxification processes.

Myth 5: Eating After 6 PM Causes Weight Gain

Reality: The timing of your meals matters less than the overall quality and quantity of your food. What you eat and how much you eat throughout the day is more important than the time on the clock. Late-night snacking can be a problem if it leads to excessive calorie intake, but it's not inherently fattening. Focus on mindful eating and listening to your body's hunger cues.

Myth 6: Crash Diets Provide Lasting Results (My Favorite!)

A crash diet is a weight loss diet that involves drastically reducing calorie intake and food variety over a short period.

Reality: Crash diets may lead to rapid weight loss initially, but they're unsustainable and often result in regaining the weight once normal eating patterns resume. Sustainable weight loss is achieved through gradual, long-term changes in diet and lifestyle. Focus on building healthy habits that you can maintain over time.

Myth 7: Supplements Are a Magic Bullet

Reality: While certain supplements can support your health, they're not a replacement for a balanced diet. Supplements should complement, not replace, real food. Consult with a healthcare professional before taking any supplements, and remember that there's no substitute for a nutritious diet.

Myth 8: All Calories Are Equal

Reality: Not all calories are created equal. While calorie intake matters for weight management, the source of those calories also plays a crucial role. Nutrient-dense foods like vegetables, lean proteins, and whole grains provide more satiety and essential nutrients compared to calorie-equivalent servings of sugary or processed foods. Focus on the quality of your calories, not just the quantity. For more details, I recommend you read our previous article called A Dietitian's 10 Rules to Eliminate Abdominal Fat.

Myth 9: You Must Cut Out Snacking Completely

Reality: Snacking can be a healthy part of your diet when done mindfully. Snacks can help maintain energy levels and prevent overeating at meals. The key is choosing nutritious snacks like fruits, yogurt, or nuts, rather than reaching for sugary or highly processed options. Portion control and mindful eating are key to healthy snacking.

Reality: A gluten-free diet is essential for individuals with celiac disease or gluten sensitivity but isn't a guaranteed weight loss strategy for everyone. Many gluten-free products are highly processed and can be higher in calories and sugars than their gluten-containing counterparts. If you don't have a medical reason to avoid gluten, it's better to focus on a balanced diet with whole foods to achieve weight loss goals, rather than going gluten-free. (

Losing weight and maintaining a healthy lifestyle involves making informed choices based on scientific evidence rather than falling for common diet myths. Embrace a balanced, whole-foods-based diet, regular physical activity, and mindful eating habits.
