Does ceviche make you gain weight?

Answer 1

Anything eaten can contribute to your weight. Any energy not used through physical activity and normal body processes can be stored in the body resulting in added weight.

Ceviche however is rather lean food, if made as traditionally with fish or other seafood with low fat content, but high nutrient value per weight unit. Nevertheless, that fat is generally healthier than fats from mammals. The preparation doesn't need any addition of energy sources as with frying, and doesn't cause loss of liquid (like evaporation), which doesn't reduce volume and hence not concentrating the fat. The amount of fast carbohydrates is low. So ceviche doesn't cause extra energy accumulation and is good food if one wants to be careful with one's weight. Preferably served with potatoes, sweet potatoes or maize (corn) for a balanced meal.
