I hike Sat and Sun about 5 miles each day. I do it because I love hiking but would like to make it fat burning as well.

I tried eating a high fat meal an hour before I hiked and took 1000mg L-Carn. It was the first time I've ever gotten hungry on a hike. It that a good sign? Also what is the best meal/ supplements to take in this case.

(I can't take stimulants I have a heart murmur).

thanks
