Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.

How do you verify the weight loss?

For all official weigh-ins, you'll be prompted to submit your official starting weight. Our standard weigh-in process involves you submitting 2 photos: one of you standing on a scale in lightweight clothing (no shoes, hats, belts, watches, coats, or outerwear), and another of the scale’s readout with your weigh-in word written on a piece of paper.

What you'll need

  • A scale (preferably digital)
  • A digital camera or smartphone
  • A full-length mirror or someone to take your photo

Yeah but why is the goal not equally split between the months, if it were it would be 2kg not 4kg i have to loose till mid June

I think it is because initially it is easier to loose the weight, but as you loose more it gets harder and the weight comes off slower. The different goals are to reflect the progression most people have and the final month of maintaining is to help us develop habits to maintain. Most people when they stop dieting gain some of the weight back.
