|Laser "needles" may help you lose superfluous body weight.|
It sounds like a marketing gag, but the results of a recent study from the Cairo University (El-Mekawy. 2014) clearly indicates that the answer to the aforementioned question is "YES! It can!"
The laser acupuncture was applied with an energy density of 2 J/cm2, a pulse radiation of 200 ns, and with a pulse frequency of 5000 Hz vertically with irradiation time 2 min/point, 3times/week for 12 weeks to the following acupuncture points:

Acupuncture and appetite control: This is not just an aliteration. The effects of classic acupuncture therapy on appetite control is also scientifically proven. Zhao et al. (2000), for example, found that "acupuncture can increase excitability of the satiety center, with a better long-term effect" (Zhao. 2000); and Liu et al. observed significant reductions of the levels of monoamine neurotransmitters in ventromedial nucleus of hypothalamus (VMH) and corresponding reductions in food intake in rodents (Liu. 2001).In addition to the three acupuncture sessions per week that was applied to 14 out of the 28 post-menopausal women with metabolic syndrome who participated in this study, all subjects had to run on a treadmill 3 times per week for 35 minutes (5 minute warm-up + 30 min at 60-75% of the heart rate reserve) and to adhere to an energy-restricted diet for 12 weeks:
Since all post-menopausal women had closely adhered to the assigned energy intake, the following beneficial effects of the laser acupuncture cannot have been caused by mere increases in dietary adherence.
"All post-menopausal women followed an energy-restricted diet for 12 weeks. First, the recommended daily kilocalorie intake was computed by multiplying the Harris-Benedict equation by 1.55. Then, daily energy intake was restricted by 1000 kcal/day (daily kilocalorie requirement-1000 kcal). The diet caloric proportion of the protein, fat and carbohydrate was set at 15%, 30% and 55% respectively.

Each post-menopausal woman was given a booklet including a database of foods, and their energy and macronutrient values. The therapist asked each woman to select her foods freely, and give instructions about planning her meals to help adhere to the prescribed kilocalories and the assigned macro nutrient.
All women were advised to keep 3-day dietary records and interviewed by the therapist weekly. The therapist checked these records to ensure the total kilocalories per day did not exceed the previous calculated one, and give any advice about the meal plans when they did not meet the assigned mac ronutrient" (El-Mekawy. 2014).
