In obesity, nutrient absorption can be affected by several factors, including gastrointestinal function and the potential need for medications that impact digestion. This can lead to low levels of vital nutrients such as iron, vitamin D, and vitamin B12, which are important for metabolic and immune health. A diet rich in whole foods—like lean proteins, leafy greens, nuts, and seeds—can support better nutrient intake and absorption. In some cases, targeted supplementation may be recommended to ensure nutritional adequacy. Effective obesity management includes addressing nutrient absorption issues to promote energy, well-being, and overall health, which are vital for successful weight management.
