In the bustling world of health and wellness, protein and snack bars have become a staple for those seeking convenient and healthy options amidst busy lifestyles. MinusCal, a company founded by Barrett Jacques and Crom Carmichael, aimed to carve its niche in this market with its fat-blocking protein bars and supplements. The key differentiator was an ingredient called Choleve, touted for its potential to aid in weight loss. However, MinusCal's journey, marked by a contentious appearance on Shark Tank and subsequent market challenges, serves as a cautionary tale in the competitive weight loss industry.
The Promise of Choleve
The MinusCal story revolves around Choleve, an ingredient that initially garnered attention for its cholesterol-lowering properties. According to Barrett Jacques, Choleve was first used to help lower cholesterol, but it also had the beneficial side effect of weight loss. Jacques, who serves as Director of Business Development at MetaPhy Health in Tennessee, highlighted this dual benefit in an article in SUAVV Magazine.
MinusCal's claims are rooted in scientific research, including a 2003 JAMA paper on a trial in China involving 240 participants that described green teas as an effective support for a healthy lifestyle. Further support came from a Kansas University study comparing Choleve to Orlistat, a prescription-strength weight loss medication known to reduce fat absorption by 25%. MinusCal extrapolates from these findings, confidently asserting that Choleve can reduce fat absorption by 12%. Notably, studies reported no unpleasant side effects from Choleve use.
MinusCal Products and Usage
MinusCal offered its products in two forms: snack bars and dietary supplements. The snack bars, available in Chocolate, Peanut Butter, and Apple Cinnamon flavors, were described by Health Journal as having a "pleasantly moist, brownie-like texture." The pill form allowed for convenient consumption up to two times daily.
The company recommended taking Choleve just before, during, or after a meal to maximize its effectiveness. While immediate results were purported, MinusCal advised that significant weight loss could be expected after eight weeks, coupled with a healthy diet and regular exercise. They also offered a money-back guarantee with a "no questions asked" exchange or refund policy.

The Contentious Shark Tank Pitch
Barrett Jacques and Crom Carmichael ventured into the Shark Tank seeking a $500,000 investment in exchange for 20% equity. Their mission was to convince the Sharks that MinusCal could effectively help people lose weight. The pitch, however, turned into a heated debate, particularly with Mark Cuban, over the validity of the product's claims.
Cuban questioned the science behind Choleve and the company's marketing, arguing that it misled consumers into believing MinusCal was a "miracle" weight loss solution. The entrepreneurs' attempts to defend their product and its purported benefits only fueled the fire. The Sharks cited inconsistent claims, flawed branding, and doubts about the technology behind Choleve as reasons for declining to invest.
Guest Shark Daniel Lubetzky raised concerns about the safety claims, asking, “Is there anybody that should avoid this product?".
Post-Shark Tank Challenges and Closure
The lack of a deal on Shark Tank, coupled with negative customer feedback, proved detrimental to MinusCal's long-term prospects. Despite launching on platforms like Amazon, the product received overwhelmingly negative reviews. Customers frequently criticized the taste and questioned its effectiveness, with some even labeling it a scam.
Ultimately, MinusCal ceased operations, and its products are no longer available for purchase. The company's failure highlights the challenges faced by businesses in the weight loss industry, particularly those relying on a single ingredient or unproven claims.

The Science Behind Tea and Weight Loss: A Deeper Dive
While MinusCal's claims surrounding Choleve faced scrutiny, the potential benefits of tea, from which Choleve is derived, have been explored in numerous studies. Research suggests that tea, particularly green tea, may play a role in weight management and overall metabolic health.
Types of Tea and Their Composition
Tea, derived from the leaves of the Camellia sinensis plant, is classified into several major types based on processing methods:
Green Tea: In green tea production, the leaves are heated to inactivate enzymes, preventing oxidation and preserving their characteristic polyphenolic compounds, known as catechins. (−)-epigallocatechin gallate (EGCG) is the major form of tea catechin.
Black Tea: Black tea undergoes enzyme-mediated oxidation, during which catechins are converted into theaflavins and thearubigins.
Oolong Tea: Oolong tea involves a limited fermentation process, resulting in a combination of catechins, theaflavins, and thearubigins.

White Tea: White tea is made from younger leaves and undergoes minimal processing, resulting in a composition similar to green tea.
Dark Tea: Dark tea, such as Pu-erh tea, is fermented with microorganisms, leading to the formation of new compounds.
Mechanisms of Action
Studies suggest that tea and tea polyphenols may influence body weight and metabolism through several mechanisms:
Decreasing Lipid and Protein Absorption: Tea constituents may interfere with the absorption of lipids and proteins in the intestine, thereby reducing calorie intake.
Activating AMPK: Tea polyphenols, such as EGCG, can activate AMP-activated protein kinase (AMPK) in the liver, skeletal muscle, and adipose tissues. AMPK activation can decrease gluconeogenesis and fatty acid synthesis while increasing catabolism, potentially leading to body weight reduction.
Evidence from Animal and Human Studies
Animal studies have demonstrated that green tea extracts (GTE) or EGCG can reduce body weight gain, adipose tissue weight, blood glucose levels, and insulin resistance in rodents fed high-fat diets or in genetically obese/diabetic models.
Human studies, including randomized controlled trials (RCTs), have yielded mixed results. Some studies suggest that green tea consumption can reduce body weight, waist circumference, and blood levels of LDL-cholesterol, glucose, and insulin. However, other studies have found no significant effects of EGCG supplementation on body weight or metabolic markers.
The variability in human study results may be attributed to factors such as the type of tea consumed, the dosage of tea polyphenols, the duration of the study, and individual differences in metabolism and lifestyle.
Cautions and Considerations
It's important to note that the bioavailability of tea polyphenols can vary depending on their chemical structure and individual factors. EGCG, for example, has lower bioavailability compared to other catechins. Furthermore, tea catechins undergo extensive biotransformation in the body, and their metabolites may have different biological activities than the parent compounds.
Lessons Learned from MinusCal
The MinusCal story provides several valuable lessons for entrepreneurs in the health and wellness industry:
- Scientific Validation: Back up product claims with robust scientific evidence and clinical data.
- Transparency and Clarity: Avoid making exaggerated or misleading claims that can erode consumer trust.
- Product Quality and Taste: Ensure that products are not only effective but also palatable and enjoyable for consumers.
- Market Research and Understanding: Thoroughly understand the competitive landscape and consumer preferences before launching a product.
- Resilience and Adaptability: Be prepared to adapt to market challenges and criticism, and continuously improve products and strategies.
