Arghhh.....nothing makes me crazier than..." no carbs...or don't eat this with that..'...' To have complieance with a lifestyle change, it must fit with the clients goals,available time and food preferences.
You must eat carbs, they are the body;s fuel,it's all about the carbs you choose. You can combine foods together, jezuzz, what a load of hogwash. And stay away from expensive supplements and powders.
The only powder I might recommend would be a good quality whey protien powder. Eat a good variety of richly colored foods, dark green,deep reds, rainbow foods. Portion control is very important. You needn't deny yourself, but moderate instead.
Keep it simple, and basic. If you are going to do this, why not do it for the long haul? What are you going to do at the end of the summer or once you have reached your desired wieght? If you have done a quick fix/wieght loss,it will all come back on,believe me.....and usually more as well.
You must learn to make heathly food choices,no fad diets, and increase your daily activity. Walking is an excellent start, but that alone will not help you accomplish your goals. You will need to do a program that uses as many muscles as possible in a short time span.
Kettlebells, "bootcamp" style, excersices will work and you don't have to pound away for an hour or more every day. Studies have shown that a min of 3 moderate to high intensity workouts a day, at 10 mins each, will help you significantly.
But.....they must be intense enough. You want to use your large muscles as much as possible. Quads, lats ect. To sit in a machine and do 6/7 sets of a bicep excercise is very time consuming and kinda pointless.
You want to reduce adipose tissue and replace it with active lean muscle tissue, which burns more calories at work and at rest,double bonus! The king of excerises, the squat, should be your best friend. Once you can safely perform a squat, the world iis your oyster. Keyword is SAFELY. The list of what you can do once you have mastered that move is endless.
As you can tell, I believe in staying away from fad foods, diets, exapensive supplements,eating 12 eggs a day( my personal fav advice from " the pro's) and learning to make smart food choices, finding a program that you like and enjoy, that is safe, and moveing towards a lifestyle change that will be easy to follow and enjoyable.
I have much much more to say on this subject, but I am a pretty slow typer....
