Weight gain the day after work out :(

Options
I am on keto for the last 2 weeks and counting calories on carb manager. I lost 3kg. Yesterday I went back to the gym, did strength training and today I weighed 1 kg more. What am I doing wrong?

    Your one-day results, whether lose or gain, mean absolutely nothing in the long run. It’s the trend that matters.

    In January I got food poisoning and lost 1.8kg overnight. (I obviously gained it all back once I started keeping food in.)

    We know food poisoning doesn’t make you lose fat, but it’s still an immediate weight loss on the scale. Why would a sudden increase on the scale show true weight gain? It could happen due to any number of reasons: more poop in your bowels, drank more water and didn’t urinate yet, water retention in muscles after a heavy workout, water retention caused by sodium, water retention caused by carbs, water retention caused by sunburn or other swell-causing inflammation etc.
