Clinically Proven Weight Loss Ingredients
What separates effective diet pills from mediocre ones?
The answer is clinically proven weight loss ingredients taken at the correct dosages.
Let’s face it, every diet pill company promises huge results, but few actually deliver. Distinguishing between the effective supplements and the mediocre ones can be difficult and that is why clinical studies and scientific evidence are useful.
Here’s a closer look at the best clinically proven weight loss ingredients available:
Green tea is an effective weight loss ingredient backed by multiple clinical trials. It supports weight loss in many ways: it provides energy, boosts metabolism, and increases fat oxidation.
Green tea also contains potent antioxidants called catechins, which protect cells from free radical damage.
To maximize green tea’s effectiveness, look for a product with a highly concentrated amount of catechins. A study published in the journal Obesity showed subjects ingesting green tea containing 583 mg catechins for 2 weeks experienced a reduction in body fat, systolic blood pressure, and LDL cholesterol.
7 Keto DHEA boosts the metabolism-boosting enzymes. When tested on humans against a placebo, 200mg/d 7-Keto caused men and women to lose significantly more weight after 8 weeks. Subjects also followed a reduced-calorie diet and exercise program.
Caffeine is proven to boost metabolism and provide energy. A study with 76 overweight and moderately obese subjects consuming 270 mg/d epigallocatechin gallate and 150 mg/d caffeine revealed caffeine consumption was associated with weight loss through thermogenesis and fat oxidation. 
Guggelsterones signal the thyroid gland to boost your metabolic rate without increasing heart rate.
Additionally, recent health research further indicates guggulsterones have powerful effects on improving thyroid production and effective cholesterol health. 
Forslean is patented coleus forskohlii, another potent metabolism booster backed by scientific research.
A double blind placebo controlled study showed females supplementing with 250 mg/d Forslean twice per day for 12 weeks demonstrated Forslean mitigates weight gain.
Fucoxanthin facilitates thermogenesis and increases metabolic rate. One study demonstrated subjects taking 300 mg/d pomegranate seed oil and brown seaweed containing 2.4 mg fucoxanthin for 16 weeks experienced reduced body fat and liver content. 
Glucomannan is a hunger reducer shown to curb cravings and reduce appetite. What’s more, a study with 20 obese subjects taking two 500 mg/d capsules glucomannan 1 hour prior to each meal experienced a mean weight loss of 5.5 lbs over an 8 week period.
How To Maximize Results?
An important thing to remember is clinically proven weight loss supplements must be taken at correct dosages to work. A diet pill can have all the best ingredients but if the quantities are too small, it’s not going to help you lose substantial weight.
Many companies use proprietary blends and don’t list specific ingredient quantities. However, they do indicate the total amount per serving. If the total amount per serving is much lower than the recommended amount needed to be effective, that supplement won’t produce significant results.
