will walking/running help me lose fat?

Diet is the key to weight loss. The cardio only speeds up the fat burning process. So yes if you walk or run for an hour a few times per week then along with lean diet you will lose weight.

Not a professional but try making walking your daily habit and have healthy food like fruits or vegetables. Instead of taking an elevator take the steps, instead of having chips have an apple. Have some tea instead of coffee. Time yourself when you walk like make it a game. YOu have to walk from your house to work in 20 minutes and no more but less. Not sure if I explained that correctly but i hope you got the idea.

2 hour walk at a moderate pace

if you re having trouble getting started make a small move such as starting an eating log or buying walking shoes you re three times more likely to follow through if you start with small gestures such as these

yes offcourse walking and running is the beneficial way to lose your weight in a fast way. it gives you the energy and burn fat tremendously.
