Raptor, I'm about to turn 74 and I got myself to my best weight ever a couple of years ago by eating mostly keto...cut all sugar, eating natural good fats, mostly no dairy, no grains of course, limit veggies to mostly green ones. I almost always managed a 14-16 hour fast between an early dinner and a late breakfast the next day. I ended up doing all my eating in an 8 hour period and I found I was good with just 2 meals a day: breakfast and dinner. When you switch your body over to a fat burning metabolism (takes a few days usually), it gets easy. No cravings, no major hunger, you end up eating less, and the weight drops off. You can do this at any age, and anyone who says you can't lose weight after a certain age is WRONG.
