carbs vs calories

irishkiss

My mom watches her carb intake and has lost 95 lbs! I am so proud of her. I watch calories and lost 37 lbs! We constantly go back and forth as to which system is best. We both exercise, by the way my mom is 71 years old! Anyway, makes me wonder if I should look into that for a while, but Im so worried about learning an new system! I dont like change....lol What do you think?
