It worked for me too when I was your age. A bunch of years later, not so much. I've been watching what I eat and trying to stick to a 16-8 eating schedule.
Every deer season since I started remote camp hunting ( about 10 years now) I've lost 20 pounds between Oct 1st and Nov 15th. I have always gained it back pretty quick once I returned to my normal routine up until the last couple of years when I've made a fairly serious attempt to reduce my at work snacking.
I always attributed the loss to lowering my calorie intake, burning more energy walking and just staying warm while effectively living outdoors. I just heard from someone in the 250 challenge thread mention the 16-8 weight loss theory and realized it describes exactly what I do during my camping season. I get up, no breakfast and head out to hunt before light. Back in camp at noon I eat a light lunch, back out to the woods and in the tree by 3:00. Back in camp after dark for a dinner followed immediately by bed. Without trying I was only eating in an 8 hour window. I think there may be something to this. I'm trying to stick to this plan in this off season to see if it helps me maintain my weight loss this year. So far, so good . . .I'm down 40 pounds from the start of the 2018 deer season.
Before keto when I was going to hunt the following day I wouldn’t eat past 7 pm night before
And go #2 before I’d leave at 4am the day of the hunt
I’d sit all day usually (2019 hang in saddle) and not eat or drink until that evening
Mostly so I didn’t have to use the bathroom
Now that I’m on keto I don’t have to use the sit down function of the toilet as much
