Very little is said about Recommended Daily Allowances (RDAs), which is a pity because they represent the maximum amount of key macronutrients you should have in your daily diet.

The key macronutrients that you need to be aware of are: total fat, saturated fat, sugar, salt and fibre. Do you know what the RDAs are for these macronutrients? Well here they are:

Total Fat 70 grams; Saturated fat 20 grams; sugar 25 grams; salt 6 grams and fibre >30 grams. (These are the levels recommended by the World health Organisation)

Keeping within your RDAs is a really effective way of keeping a check on your diet, making sure you don’t compromise your biochemistry by eating too much of the wrong thing. Too much sugar and too much saturated fat, for example. What does biochemistry mean? Your biochemistry is a network of chemical processes which maintain and regulate your life. They keep you ‘in sync’ and ‘in tune’. Exceed your RDAs and over time you will cause your biochemistry to malfunction. The result? You lose control of what you eat and how much you eat and you put on weight – lots of it.

Keeping within your RDAs is a very sensible thing to do if you want to lose weight and stay slim.
