Helooo friends !!!!
This is ALan Smith I am Working as a content writer
I am bit bulky so loose the weight I have joined the
Gym. Still I have not concentrated on my diet so please
suggest me Low Carbohydrate Diets.....

If he wants someone to suggest a low carb diet I've long been biased in
favor of Doctor Atkins New Diet Revolution. Any of the editions 1972
(without the word New in the title), 1993, 1999, 2002 or the latest one
written post-mortem by a team of doctors at the Atkins Center.

There are plenty of other popular low carb plans and they all have their
fans. They are all good plans. Picking a plan based on long term
popularity works just fine. Just follow the directions of your chosen
plan including the parts that you don't understand or disagree with.
The authors of these plans work on them a decade and more and they
figure out stuff that's not obvious that works better than the obvious.

If all he has to go on is exercise that can be simple. To lose a
kilogram of fat run about two marathons. If he wants to use exercise to
lose 5 kg per month that's running a marathon every three days.
Being heavy makes running harder so it might not even be possible to
achieve the type of physical conditioning it takes to run a marathon.
Chicken and egg. Look at the folks on the TV show Biggest Loser. They
spend all day every day in the gym.

Running the arithmatic on exercise it becomes easy to understand why
exercise is very good at preventing regain but not nearly as good at
causing loss in the first place. Of course exercise plus diet works
better than either exercise or diet but both together work best.
