My best weight loss, post 50 years old, was last year. I'm 5'8" (lost an inch!!). I went from 220lbs (maybe a tad more) to 188lbs from March to September. I did this by cutting out the post 8PM snacks, careful about what I ate at meal time, but did NOT go on a specific diet, and rode a bike not less than 2 time per week, and many time 4 times a week. Being a Quality Engineer by trade, I plotted the weight loss. It worked out to exactly 1 lb lost per week. The winter was going well for me having put back only 6 of those 32 lbs. But the last two weeks the weather has been awful so I'm guessing I've gained an additional pound or two. Time to get on the trainer and hold until riding season begins in 6 weeks!
