How about a adiponectin field ? Adiponectin leads to more fat loss . Low adiponectin is associated with dementia, insulin resistance,diabetes mellitus and artherosclerosis.
From wikipedia:
Transgenic mice with increased adiponectin show reduced adipocyte differentiation and increased energy expenditure associated with mitochondrial uncoupling.[13] The hormone plays a role in the suppression of the metabolic derangements that may result in type 2 diabetes,[10] obesity, atherosclerosis,[8] non-alcoholic fatty liver disease (NAFLD) and an independent risk factor for metabolic syndrome.[14] Adiponectin in combination with leptin has been shown to completely reverse insulin resistance in mice.[15]
