A good acid-base balance is vital for the most important of metabolic processes. Hyperacidity prevents fat from being broken down and burned off – which means, among other things, that an overly acidic diet slowly but steadily can lead to weight gain. This is because, when fat is broken down, it produces large quantities of acids that have to be removed by basic minerals (magnesium, calcium, potassium, zinc, selenium and iron). But if these basic minerals are not present in sufficient quantity because of an acidic diet, the breakdown of fat is restricted.
To lose weight successfully, you need to keep an eye on your acid-base balance, in other words, make sure you eat in such a way that not only do you get all the nutrients you need, but also in balanced proportions. If you do, you’ll keep your fat-burning capacity active.
