Certain foods can help promote weight loss when consumed as part of a calorie-controlled diet and regular exercise routine. Protein-rich foods like chicken, fish, eggs and legumes help keep you feeling full for longer. Foods high in fiber and water content such as fruits and vegetables also aid weight loss by bulk up meals while providing few calories. Replacing sugary drinks and high-calorie snacks with water, unsweetened tea and coffee can further assist in weight management.
