Not sure what will work for you, but I lost 40lbs by riding my bike 12 hours per week, and cutting processed sugar from my diet.
Now I’ve moved on to hypertrophy lifting with Caroline Girvan 5 days per week, and riding bike 6-8 hours per week. I’ve gained 5 lbs back, but its muscle and is fine.
Also, oatmeal with a fruit (either blueberries, strawberries, banana, or raspberries) in it every morning for breakfast
I regularly bisect commits in the range of 200k (on the low end) for finding causes of bugs. It takes me minutes. Pretty crazy
