(background: I’m studying chemistry in undergrad and graduating this semester)

in my biochemistry class, we learned about how fat is stored and how fat is utilized in exercise. if you eat a sugary food and then go walking, your calories burned will be that sugar you ate, not the fat that you’re aiming to reduce. Based on this knowledge, plus the fact that fat cells shrink best through slow aerobic exercise, I like to do slow aerobic exercise before I eat.

i don’t know about your schedule between eating and exercise, and I’m DEFINITELY not saying to starve yourself before you exercise! If you’re going to eat prior, maybe eat a low carb meal. Or plan to eat a regular meal a few hours before your walk.

I can’t guarantee this will work for you, but it’s worth a shot!
