Protein. How much?

How much protein do I really need?

Sorry, there's no definitive answer. Every expert has a different opinion. Here are a few examples:

Let's start with  research... suggests that the type of sport you do has an effect on the amount of protein you need. Strength sports  people need approx 2.0 gms of protein per kg of bodyweight per day.  Athletes who need speed first, then strength, then endurance need about 1.7g/kg/day & endurance athletes need 1.4g/kg/day.

This requirement is based on a high level of training, 3-4 hours a day. If you are only training 1-2 hours a day, your requirement will be less, by approx 0.3g/kg/day. For an 80kg man doing 1-2 hours riding a day, this would be 80 x 1.1g = 88g per day. Doing 3-4 hours riding, he would need 80 x 1.4g = 112g. NB : These are his rough guidelines only, each person will have different individual needs.
