Three days, really? I'm just imagining the sheer mass of watermelon you had to get through. Did you even consider what all that liquid and fiber would do to your plumbing, or were you just picturing the quick weight loss? My guts are cramping just thinking about it.
Every watermelon diet ignores the pounds of rind left over. @alice_wright36, your plumbing point is valid, but all that waste heads straight to landfills. It takes weeks for those rinds to break down, releasing methane in the process. We talk about quick weight loss without seeing the bigger picture of resource use. Short term gains like this often have hidden costs we don't count. That much fruit consumption isn't just hard on your body, it's hard on the planet too.
