If you want to keep it simple then its as everyone has said, cut your calorie intake. If you consume less than what you burn in a day, then you WILL lose wait............... its that simple........
IMO walking is the best way to burn fat too, so keep up the walking. Fat burning works best at a lower heart rate, so dont be going crazy doing intense workouts.
I do 30 mins walking on the treadmill 4/5 times a week on a full incline whilst actually eating 6-7 time a day. and i've shifted a stone and a half in the last 2 months and managed to retain most of my muscle.
Wot he said!
Crazyface, like you I am a fat tw** , hence I'm on a fitness campaign.
To lose weight you need to be burning off more calories than you put through the cake-hole, and there is no substitute for exercise to burn off calories.
The good news for us lardy-boys is that you do not need massively intense workouts to get the heart at the correct rate for fat-burning. Running flat out raises the heart rate way up above the most effective fat-burning level, so for most people a mixture of fast walking and light jogging gets the rate about right. Fast walking is meant to be excellent. If you can do this for at least 30 minutes about 4 times a week that is ample.
One thing worth looking at is body fat percentage. Mine was right up over 30, horrendous! Once you find out what it is it really focuses the mind on what you are eating!
What you are eating, how much you are eating and when you are eating all play a massive part too.
Anyway, all this might sound a lot but in anutshell it's get the right exercise and slightly change your eating habits.
Oh, and a piss up after a good work out gives you particular satisfaction!
