How much protein should i eat when trying to lose weight?

1 gram per kilogram: Your body requires approx. 1 gram of protein per kilogram of body weight per day. Much over this may start to put some stress on your body to metabolize and break it down. That said, it is true that protein generally results in more satiety and you don't get ravenous as soon. Starches and carbohydrates can cause your glucose to rise then bottom out later, increasing hunger.

120gm per day averag: 1. Weight in pounds divided by 2.2 = weight in kg 2. Weight in kg x 0.8-1.8 gm/kg = protein gm. Use a lower number if you are in good health and are sedentary (i.e., 0.8). Use a higher number (between 1 and 1.8) if you are under stress, are pregnant, are recovering from an illness, or if you are involved in consistent and intense weight or endurance training.
