Mid-thirties here, 6 months ago I started taking my diet seriously and 3 months ago I started with regular exercise and weight lifting. I’ve lost over 30kg, back to a healthy weight, and starting to see muscle definition. More importantly than the visual changes, I feel a lot better, better than I did at pretty much any age. I wish I started sooner with this but I’m confident if I keep it up it will have a major, major impact on my quality of life as I grow older.
