I'm the same height as you and now 62. LCHF has permitted the best, sustainable weightloss of my life, all after age 50. After 35 years of yo-yoing, for me this is the only satiating WOE for losing & maintaining. I did tweak by eliminating my inflammatory foods (dairy protein, grains, soy) and got below 150 lbs, where I always got stuck when younger than 50. Rate was 0.5 to 1 lb/week, slowing down for the last 15, but it kept moving. Now I maintain with intermittent fasting (a 4-10 hr eating window).
