Ok, so you want to loose weight .
DONT SKIP BREAKFAST.......DONT SKIP ANY MEAL......EAT MORE OFTEN.........YES I INTENDED TO SHOUT.
Sorry just wanted to make sure you heard that.
Never ever ever skip meals if you want to loose weight. Or exersize on empty.
Ok dieting 101....short version.
Our bodies are designed to cope with extreme environment. We know this because we are still here, even after nuking, starving, druging, and drinking ourselves into oblivion.
you eat to little, or skip a meal or eat your first meal to late, and keep this up whilst you try to loose weight, and your body yells...DROUGHT......... and switches to starvation mode.....it stores everything it can get its grubby little lips round...and begs for more constantly.
You feed it a little, often, say small meals every 2-3 hours, up to 6 times a day.....it yells.......HELLO HEAVEN....THE TIME OF PLENTY IS UPON US.... and thinks, blah I can throw this away, i'll get more in a few hours.
You change your metabolism. Your body gears up for a time of plenty, a lean, mean time when it never knows hunger.
Small meals often has another added bonus....you have to plan ahead, make double, freeze them, so you have food for work, lunch, snack, supper....its hard work, your food obsession is switched from wanting food, to being sick to death of trying to plan and fit 6 small meals into every day. Then comes the apple, bannana, for a quick meal and hay presto 5 portions a day....he he , snuck in there didnt they.
If you exersize before breakfast you are teaching your body to push itself, call on its fat stores....so yes you burn fat....
only if your body is a fine tuned machine that knows you are going to feed it, and not a recent food hording machine that will panic and switch straight back to starvation mode.
So if you must exersise before breakfast, as some have too....grab a smoothie, light on the old tum, and food to tide you over.
Get to the gym, or buy weights....if your going to loose all this weight, you will have to fill the gaps with muscle if you dont want to have lots of flabby bits...light high rep sets to tone and shape, and burn fat longer.
Lots of squats and lunges, build up steadily...they will help build the muscles round your knee's lower back and but to support the new usage and help ease the strain on them, especialy the knee's and lower back. If you start to suffer in your cycling you are less likely to continue. Kettle bells are a great workout, strength plus cardio, but a good class is essential....
And most important, keep the exersise enjoyable, you will not succeed if the exersise becomes a chore..try everything until you find something you enjoy so much, you would do anything to be better at it, thats 90% of the battle won..enjoy your cycling, set yourself realistic goals. More will be acheived by several small steps rather than one unreachable one, patience.
I used these principles .....I went from a size 24 to a size 10 in just over 12 months...I've had 6 kids, I have no flab and I love my cycling. All the best.
