In the modern world, we are constantly exposed to a multitude of weight loss tips, fads and trends; all promising everyone’s dream, fast weight reduction, clear skin or endless energy. From keto to juice cleanses, the world of nutrition is packed with advice that isn’t just wrong — it can also make it difficult for us to know what truly is healthy.

Most myths arise as a result of overly-simplified interpretations of scientific studies, things that are trending on social media or anecdotal advice without much in the way of hard data. If we buy into these fictions, it could mean malnourishment, low energy levels and a fantasy of what our bodies should look like. Knowing the reality about popular misconceptions about diet can help people make wiser decisions about their entire life, not just physical appearance.

Nutritionist Dr Ayesha Verma from Vinayak Hospital tells Moneycontrol about the reasons why these diet myths exist, “It’s easier to follow simple advice but when it comes to nutrition there is no magic formula.”

Carbs Are the Enemy

Not all carbohydrates are bad. Grains, fruits and vegetables supply many valuable nutrients (including antioxidants) and the fibre necessary for proper health. We should not give them up completely, as it is harmful for us and fatiguing.

Eating Fat Makes You Fat

Brain function and hormones depend on healthy fats, namely those from nuts, seeds and olive oil. Cutting out fat altogether can be damaging to your metabolism and overall health.

Not Eating Will Make You Thin

Meal skipping can slow your metabolism and lead to overeating later. Regular and nutritious meals will keep your energy up and ward off unhealthy cravings.

Detox Diets Are Necessary

Your liver and kidneys do an excellent job of naturally detoxifying your body. Detox diets based on such fads tend to be unnecessary and can deplete the body of necessary nutrients.

All Calories Are Equal

The 100-calorie chocolate bar isn’t the same nutritionally as the 100-calorie serving of veggies. So does quality, not only quantity.

Supplements Can Replace Food

Supplements can fill in some gaps, but they don't provide the full range of nutrients and benefits found in whole foods.

Eating at Night Makes You Fat

It doesn't matter when you eat or how many meals, it matters total daily consumption and activity level. Late meals themselves don't make you fat, as long as they're part of a balanced diet.
