Lose it slowly, eat a nutritious diet, stay hydrated, keep fit.
The creams with pregnant women on the front can't hurt either I'm sure but I'd question if you needed them.
Remember, just 1lb a week is a stone every quarter - how long did it take you to put the weight on?
Well I've always been overweight, I've not had any rapid increase or decrease at any period, it's just slowly increased over the years (I'm 24 right now), although the last 6 months or so I have pretty much been stable at around 18 stone.
I have been making sure I've kept up my fluid intake, and my diet is on track so that's good. keeping fit is a little harder as due to flat feet and a bad knee running isn't really an option (although I'm hoping as I lose weight and there is less pressure on my knees and feet that I can start running, and my end goal I want to reach fitness wise is a 11 min mile and a half at least), but I have been using a rowing machine, doing burpees, some star jumps (this really seems to get my heart rate up) and some light weight training (using weights that I can manage sets of 12 to 15 reps per set).
When you say aim for 1lb a week, if I lose more than that should I ease off on the exercise or should I try and put more time into weight training to build more muscle while losing fat?
