I've lost 20kg over the last 5 months. Got another 10kg to go til I'm at my usual winter weight, just gotta keep it off til next summer and drop another 10kgish.
Not much, but it's mine and I did it without drastically changing my life.
tips hat the biggest change I made, besides only drinking on either Friday or Saturday, was starting a new job where it's a 1.5km hike up a 45°+ slope. Then obviously back down at the end of the day.
