The fundamentals of healthy snacking involve choosing nutrient-dense options that satiate hunger without excessive calories. Focus on incorporating whole foods, such as fruits, vegetables, nuts, and yogurt, which provide vitamins, minerals, and healthy fats. Portion control is essential to prevent overeating, and being mindful of added sugars or processed snacks is key. Healthy snacking can support a balanced diet by maintaining energy levels, regulating blood sugar, and helping to achieve long-term weight management goals.
