Others will probably give you advice about the diet, but you must be warned
of something. If you're just starting an exercise plan, especially with body
building, and especially if you have never exercise before, you *will* build
muscles quickly. This will translate into weight *gain*. So, you will have
to take what the scale shows with a grain of salt, because you might be
losing fat but gaining muscle mass. Remember that what is important is your
body fat%, not your overall weight. You might want to use a meter to see
real progress, such as checking your waist line or wherever you have fat to
lose (muscle is more compact than fat, so you should lose inches). Or you
can use a scale that displays body fat%, though they seem not to be accurate
for some people. Or have someone competent at the gym check you with
callipers, which is more precise.

Just keep on with the exercise permanently because if you have just started exercise, you haven't seen the benefits yet.  
 Hello dear members of the alt.support.diet. I'm a 27 years old man with a few extra pounds I want to lose over the next months. I've started with aerobic sport training (basketball) and anaerobic also (body building) and I would like You to provide me with a diet  please.

 Many thanks.

My first suggestion would be to visit newsgroups devoted to aerobic
exercise and misc.fitness.weights. You will get a lot of advice, much
contradictory. My own suggestion is to eat wholesome food and note
that exercise and not diet is what builds muscles, power or endurance.

Any reasonable diet that is based around meat, fish, vegetables,
fruits, eggs, grains etc, will do great for a healthy, fit young
person. (as you have described yourself)

Time and consistency in exercise are your friends.
