Weight Watchers (WTW), the well-known provider of solutions to those who want to shed a few extra pounds, issued Q3 numbers on Tuesday. While losing inches is always a popular activity, that doesn't mean that the company will always see growth.

According to the corporate press release, Weight Watchers saw an 8% decline in net sales. Earnings per share came in at 68 cents on a diluted basis. That was only a penny better than the year prior. Management is certainly making the most of its revenues by keeping costs and expenses down, but it is obviously disappointing to shareholders when income expansion is dependent on belt-tightening.

NutriSystem (NASDAQ: NTRI), a weight management and fitness products and services company, is recently down $10.57 to $37 in pre-open trading, some 22%.

• Thomas Weisel says: "3Q fundamentals crumble; we expect challenges into FY08."
  
• NTRI overall option implied volatility of 59 is above its 26-week average of 47 according to Track Data, suggesting larger price risk.

• LDK shares were weak on 10/3 on allegations of inconsistency in inventory reporting.

• LDK October option implied volatility of 131 is above its 12-week average of 69 according to Track Data, suggesting larger risk.
