Some of the diets and exercise regimes on this thread are mental, I've lost 16kg and gone from 26% to 15% body fat in just over a year by doing a lot less than others on here. Using my fitnesspal to try to lose 1/2 or 1lb per week depending on how I felt has worked - usually that was 250 or 500 calories under what I needed daily. I've still eaten crisps, cakes etc but not as much as I used to and have eaten more fruit generally. Also relaxed completely for a month over xmas and been on all inclusive holidays where the diet has gone out the window. Never tended to drink much other than holiday so thats not been an issue and has helped me lose weight.
As well as eating better I've walked a lot more (tried to do at least 2 miles per day) and usual done 2/3 20 min kettle bell workouts as well as playing cricket. This may sound crazy but one thing that helped me was eating sweets. Instead of eating crisps and chocolate bars I've taken to eating liquorice toffees, werthers or chocolate and lime sweets - I find 3 or so of them keeps me from eating loads of other stuff and although probably bad for my teeth is a lot less calories. Not as healthy as other stuff but for someone who likes their food and snacks its helped.
Kind of related to this I'm now ok with my weight but want to add on some muscle and get fitter. I'll never be a gym addict or do loads of fitness stuff but I plan to do kettle bell workouts as much as possible, play cricket and walk a lot. Is it worth looking at protein shakes or do I need to be hitting the weights more to make protein shakes worthwhile? Any tips to keep the weight off and get stronger?
