I have been keeping a protein diary for the past week because I have suspicions that my diet is lacking in protein for my athletic needs. For cyclists, the basic dietary protein requirements are as listed:

Strength: 1.6-1.7 grams of dietary protein per kg of body weight
Endurance: 1.2-1.4 grams of dietary protein per kg of body weight

At 122 lbs (55 kg) of body weight I need 72 gms of protein daily for endurance and 88 gms of protein daily for strength.

The results of my protein diary for one week are listed below. A lot of the amounts were estimated since I did not measure anything. Also, I made an effort to eat more foods that are high in protein during the observation week, such as peanut butter, edamame, ham, bacon, chicken and beans.

11/6: 72 grams
11/7: 84 grams
11/8: 77 grams
11/9: 48 grams
11/10: 64 grams
11/11: 49 grams
11/12: 69 grams

Conclusions I have drawn from this one-week observation:
(a) I'm not eating enough protein for my training requirements.
(b) It is really hard to eat 70-80 grams of protein in one day. I drank milk and Isopure almost daily to get an extra 35 grams down the hatch.

I'll continue to prioritize eating meat for meals and consuming one 25 gram scoop of Isopure with skim milk daily.

Also, the quality of my diet sucks.
