Skipping meals can negatively affect metabolism by slowing it down, leading to potential weight gain and energy deficiencies. When meals are missed, the body may enter a state of starvation mode, causing it to conserve energy and store fat more efficiently. This can trigger cravings and lead to overeating in subsequent meals, disrupting a balanced diet. Maintaining regular meal patterns helps sustain metabolic health and provides consistent energy levels, promoting overall well-being.
