U.K. Pastry Shop Says Its Italian Cake Bars Boost The Metabolic Rate

A London-based start-up patisserie claims that its Italian pastries – in the form of cake bars –  contain a blend of natural ingredients that encourage the body to burn calories. The line of nine bars in a variety of flavors contain L-carnitine, guarana and green tea, all of which purportedly boost the body’s metabolic rate. Each bar also packs between 110 and 150 calories, but the bakery doesn’t say whether the calories burned equals the calories consumed. The founder of Klever Kalories says it hopes to expand its product line to cupcakes and savory snacks, such as crisps (AKA potato chips).
