How to do a Low carb diet

A low carb diet consists in cutting back on simple carbohydrates, like white rice, pasta and bread. To compensate this reduction, you should increase your intake of proteins, such as meat and eggs, and healthy fats, which are present in foods like avocados, chestnuts, olive oil and fish, such as sardines and salmon.

This diet is very effective for losing weight, because the metabolism works better with an increase in protein and healthy fat intake, helping to reduce the body's inflammation and fight fluid retention. See which Foods are rich in carbohydrates.
