Also, she says in that video that she always drinks loads of water but the downside is never being off the toilet. I don't know about anyone else but whenever I try to drink more water, yes the first couple of days you're popping to the loo often, but then your body gets used to it. Which also makes me think she's lying about it? Why would she say these things? Just don't say anything instead of lying.
Either that or she's pre-diabetic or is genuinely drinking about 6L of water which I doubt.
I was shocked at the cycling clips. I've been larger than Demi but have never been that out of sorts from cycling. A lot of large people find things like cycling the best form of exercise because of naturally strong legs but it just reflects how little physical activity she does.
