So, what exactly do we know about these lollipops — besides that Kim thinks they're "literally unreal"? According to the FlatTummy website, they're lollipops made from sugar and a "clinically proven safe active ingredient extracted from natural plants" called satiereal, which makes you feel full and suppresses your appetite for hours. Wow, there's a lot to unpack here.
A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
