Formulated to help control appetite, reduce body fat, enhance metabolism, increase energy and control fat and carb-digesting enzymes*
Lose weight and get lean fast*
takes a multi-faceted approach in helping you burn fat, increase energy and get lean.* It includes the core ingredients green tea extract, bitter orange and Sinetrol® Xpur Extracts plus L-tyrosine and caffeine (100 mg). Sinetrol® Citrus Extract decreases body fat*
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. Plus, it has green tea extract to further supercharge your results.
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.EGCG from green tea accelerates fat loss*
To boost your metabolism, Diet Stack
is loaded with green tea extract. It's standardized to contain a high level of a unique fat-fighting compound called EGCG (Epi-Gallo-Catechin-Gallate). Research shows EGCG enhances the effects of your body's own fat-burning substances.* In one study, 66 overweight subjects lost an average of 7.7 pounds over a period of 12 weeks taking 135 mg of EGCG from green tea plus caffeine twice daily (morning and mid-day). They also dropped 4 centimeters in waist size. Diet Stack
includes the same amount of EGCG (270 mg per day) that showed fat-burning results.*
Another study showed participants, without exercising, 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.*
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).
Bitter orange attacks fat and boosts metabolism*
Bitter orange contains alkaloids (synephrine and four others) that directly stimulate the body’s beta-3 receptors. These receptors act like sparks that ignite your metabolic rate and energy levels to help increase fat burning. Bitter orange also indirectly helps release body fat by stimulating your body’s powerful natural fat burners, epinephrine and nor-epinephrine.
In one study, 9 women were placed on a 1,000 calorie per day high-protein, low-carb diet for 2 weeks. During the first week without bitter orange, the mean weight loss was only 2 pounds. During the second week, they were given bitter orange (total of 52-65 mg of synephrine alkaloids per day). Weight loss increased dramatically to 5.25 pounds for the second week. This result is particularly significant since part of the weight loss in the first week of any diet can be attributed to water loss. Diet Stack includes the same amount of synephrine alkaloids (65 mg per day) that showed results.*
Our bitter orange extract has been awarded four United States patents for its ability to mobilize body fat and increase metabolism, increase lean muscle and decrease body fat, suppress appetite, and to improve overall athletic performance.* 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-tryosine, the body cannot support maximum fat burning regardless of how few calories you eat or how much you exercise. Directions
Take 2 capsules twice daily.
