Protein
You all have heard me go on about protein consumption. The US RDA of protein is only enough to keep you alive, not support muscle growth nor good health. It was developed around the time of WW II when protein was in short supply. Today we know that you need double to triple the amount to be healthy! As you age your ability to process and utilize protein declines, hence the increased amount of protein required to keep you healthy.
Why eat protein? First it is satiating, you will feel fuller eating your 30 grams of protein first on any meal than waiting until after the bread has been served. Eat protein first then veggies, bread last.
While I have this as second, it is super critical as a woman who eats about 1.5 to 1,7 grams of protein per kilo of body weight you will have a greater chance of maintaining healthy muscle mass as you age. Eat less protein you have a greater chance of become frail regardless of how much you workout! By the way the US RDA of protein is 0.6 grams of protein per kilo. Convert pounds to kilo dived the pounds weight by two and subtract 10% (150 lbs/2= 75 75-7.5 = 67.5 Kg)
