Hi! I'm 53, 174 cm (5' 8½"), male. Been using Fitbit since April 2013 (One) and June 2013 (Aria). I weigh 65.6 kg (145 lbs), 54.9 kg of which is lean mass and 10.7 kg is body fat (16.3%), as per my Fitbit Aria. Let's say I'd want to lower my body fat to 15.0%. Which of the following approaches would be optimal: 1) keep lean mass unchanged (54.9 kg) and lower body fat to 9.7 kg (15%), for a total weight of 64.6 kg (-1.0 kg) / BMI: 21.3 2) keep total weight unchanged (65.6 kg, BMI: 21.7), increase lean mass to 55.8 kg (+ 0.9 kg) and lower body fat to 9.8 kg (- 0.9 kg) 3) keep body fat unchanged (10.7 kg) and increase lean mass to 60.6 kg (+ 5.7 kg), for a total weight of 71.3 kg (+ 5.7 kg) / BMI: 23.6 I suppose 1) and 2) could be achieved mostly by adjustments to what I eat, while 3) would require significant changes to my workouts, right? Some background about my current eating and workout habits: I don't follow any particular diet, though I do try to eat sensibly (lots of vegetables, meat only about once a week, I only drink water). However, I don't restrict my food intake (if anything, I eat more since Fitbit has made me much more active) and I don't count calories in. I do eat a lot of carbs (pasta, rice, dark bread, but not too many sugary things) and full-fat cheese (my weak point). My activity consists mostly of power walking and running (about 20,000 steps and 90 minutes of VAMs per day in average). Thanks in advance!
