Burn fat and control appetite with Diet Stack*

Lose weight and get lean*

Diet Stack™ takes a multi-faceted approach by helping you reduce body fat, increase energy and lose weight when combined with calorie reduction and regular exercise.

Core ingredients include:

  • Green tea extract
  • Sinetrol® Xpur Fruit Extracts
  • Caffeine (150 mg)
  • L-Tyrosine
  • Bioperine® black pepper extract


Decrease body fat* with Sinetrol® Fruit Extracts 

Sinetrol® Xpur is based on three citrus fruits of the Mediterranean diet: sweet orange, blood orange and grapefruit. It also contains an extract from the berries of the tropical American plant, guarana. Each of these extracts contain specific bioactive flavonoids that have been shown to boost lipolysis (fat breakdown).* In one study of 95 healthy overweight volunteers, the group taking 450 mg of Sinetrol® Xpur twice per day had a greater decrease in body fat (-9.7% vs -3.2%) and a greater decrease in waist circumference (-5.7% vs -1.5%) than placebo after 12 weeks.*

In a second review of the study, those taking Sinetrol® Xpur were able to decrease their body weight (-3.7%) and abdominal fat (-9.7%), as well as waist (-7.5%) and hip (-5.3%) circumference. These changes were significantly greater than those in the placebo group. The Sinetrol® Xpur group also had highly improved perceptions of well-being, energy gain and overall satisfaction.* Diet Stack contains the same 450 mg dose of Sinetrol® used in these studies.

In another study, abdominal fat percentage was significantly decreased by 9.73% after 12 weeks in the group taking Sinetrol® Xpur. Waist size and hip size were also significantly decreased by 2 inches after 12 weeks, and there was 10 times more free fatty acid release in the Sinetrol® Xpur group.


Accelerate fat loss* with EGCG from green tea   

Boost your metabolism with a high level of a unique fat-fighting compound from green tea called EGCG.*  One study showed that using a combination of EGCG (same amount as our formula) and caffeine resulted in an average weight loss of 7.7 pounds over a 12-week period.*

Another study showed participants burned up to 200 more calories a day compared to a placebo (precise measurements were done in a metabolic chamber). That equates to almost a half a pound of body fat burned per week from green tea alone.* 

Green tea extract improves exercise performance*

In January 2015, green tea extract was shown to improve more than just body composition when researchers tested its effects on exercise performance. To make sure the benefits were coming from green tea and not caffeine, they used a dose of 571 mg of decaffeinated green tea extract per day.  

Before, during, and after the four-week study period, the men cycled for one hour at half their aerobic capacity, then took a 40-minute performance exercise test. After four weeks, while the placebo group had not changed, the decaffeinated green tea group burned fat at a 25 percent faster rate, increased performance distance by 10.9 percent, increased average power output by 22.7 percent, and had 1.63 percent less body fat.

The researchers commented that supplementation with green tea extract increased the amount of fat used as fuel, making the body more efficient, resulting in improved exercise output.* Similar to this study that used a 571 mg daily dose of green tea extract, Diet Stack™ provides a 600 mg daily dose (2 capsules, twice daily).


L-Tyrosine fuels your fat burners*

The amino acid L-tyrosine is a metabolic precursor to bitter orange and green tea extracts. It can help enhance your body's production of its own natural fat burners. Without plenty of L-tyrosine, the body cannot support maximum fat burning regardless of how few calories you eat or how much you exercise.
