Low Carb Diet Question?

Another recent comment I made at Yahoo Answers regarding low carb diet

S posted:

I am 5’10” 165lbs fairly athletic build and fairly active. Recently single im looking to tone everything up and for the last two weeks I have been sticking to a diet of no more than 50 carbs and around 1700 Cal’s per day. I am wondering if I am on the right track here and accepting all input. 

My question is should I go off my diet for a meal to a) reward myself for sticking with this for the two weeks and to b)Spike/confuse my metabolism to get it to work harder or would this just negatively affect my diet and set me back?

Thanks in advanced.

My response:

Hi S,

There’s a very simple answer to this, if what you’re doing now is working and you haven’t yet reach the goals you’ve set for your body, then I would suggest you keep doing what you’re doing until you do and then reward yourself with something absolutely fantastic for achieving the goals that you’ve set yourself.

Hope that helps,

Mark
