Formulating innovative products with solid efficacy requires addressing, as much as possible, the underlying physiological and biochemical contributors to developing a given condition. This approach couldn’t be more apparent than when formulating products for weight management. Much more is involved with weight management than just balancing calories consumed and burned.
Like a child learning that square pegs go into square holes and round pegs go into round holes, the same strategy should be taken when formulating for success. While sandpaper could be used to make the pegs fit, what would that accomplish? The key is to select the proper ingredient(s) with proven efficacy at precise dosing. At the same time, a formulator should consider choosing ingredients with differing mechanisms of action to increase the likelihood that a product will work.
Numerous unique yet interconnected areas should be considered when addressing these underlying physiological connections to weight control: leptin, ghrelin, AMP-activated protein kinase (AMPK), inflammatory cytokines (tumor necrosis factor [TNF]-alpha/interleukin [IL]-6), insulin, insulin resistance, pituitary (primarily cortisol), adiponectin, oxidative stress, microbiome and sleep.
The area of weight management offers many opportunities to address the underlying contributors with scientifically substantiated ingredients. The following are some of the key players in each area with demonstrated weight management benefits. The list is not definitive, nor are examples exhaustively documented (but links to research studies are provided to start digging in). The information should be considered a guide to seeking ingredients with science showing they address an underlying mechanism of action and include evidence they work for weight management.
Taking a quick look at each of these, one can see many contributing factors are going on beneath the surface.
Leptin
Leptin is a hormone that fat cells produce to regulate body weight by signaling satiety and appetite suppression in the brain. It also influences the regulation of blood sugar levels and metabolism. In some cases, people who are overweight may develop leptin resistance; i.e., the body is producing leptin, but it doesn’t get utilized or recognized. When this occurs, it will trigger the desire to eat even though a person should be satiated.
• African mango, or Irvingia gabonensis, (as IGOB131, from Gateway Health Alliances) increases levels of adiponectin and promotes healthy levels of leptin.
• Lepticore modulates leptin.
• Lemon verbena (Aloysia citriodora) and hibiscus flower extract (as Metabolaid from Monteloeder) significantly increase and decrease adiponectin and leptin, respectively, while the inflammatory-related factors TNF-alpha and IL-6 were downregulated.
Ghrelin
Ghrelin is made by the stomach when it is empty. Therefore, ghrelin increases food intake and fat deposition and plays a role in decreasing energy production. Since ghrelin production begins in the gut, the microbiome also plays a vital role
• To date, no documented supplements are known to suppress ghrelin levels directly.
AMPK
AMPK influences glucose utilization, oxidation and appetite (increases energy production). In short, boosting AMPK activity results in a healthier metabolic status, which can lead to less fat production.
• Jiaogulan, also known as Gynostemma pentaphyllum (as ActivAMP, from Gencor), was shown to reduce TNF-alpha and activate the AMPK enzyme.
• Fucoxanthin/pomegranate seed oil (as Xanthigen from PLT Health Solutions) activates AMPK and suppresses lipid accumulation through multiple mechanisms.
• Bergamot (as Vazguard, from Indena S.p.A.) activates AMP.
