The Science of Weight Loss: Facts vs Myths

TLDRTo lose weight, you need to create a calorie deficit by either reducing your calorie intake or increasing your calorie expenditure through exercise. Different diets may have varying effects on weight loss, but ultimately it comes down to the total calorie balance. Healthy weight loss involves a balanced diet of carbohydrates, proteins, and fats. Carbohydrates should come from whole grains, fruits, and starchy vegetables. Fats are essential for hormone balance and nutrient absorption. The recommended percentages for macronutrients are 45-65% carbohydrates, 20-35% fats, and 10-35% protein.
