Many myths surround weight loss and fitness, such as the idea that carbs must be completely eliminated or that spot reduction is possible. Another misconception is that exercising for long durations is the only way to effectively lose weight, rather than focusing on intensity. Additionally, some believe that lifting weights will make women bulky, when in fact it can aid in achieving a toned physique. Lastly, the notion that supplements alone can replace a healthy diet is misleading; balanced nutrition is essential for effective weight loss and overall health.
