A long-term, unbalanced diet can have serious implications on health, leading to a heightened risk of developing chronic diseases such as obesity, diabetes, and cardiovascular issues. An imbalance between macronutrients—too much sugar or fat and not enough fiber, vitamins, and minerals—can result in nutrient deficiencies and metabolic disturbances. Poor dietary habits may also lead to systemic inflammation and affect mental health. Over time, the accumulation of these factors can adversely affect overall health, reducing life quality and longevity, and eventually requiring medical interventions for various conditions.
