How did I gain weight??

Try not to focus on daily fluctuations. Unless you overate by a lot, it's impossible to gain fat. It's just water weight. Stay hydrated and the water weight will come off. I fluctuate up to 5 pounds from morning until night.

Weight loss isn't linear. You can do the same exact thing one week and the same the next and get different scale results because there are other variables to take into account. Stress, hormones, and environment (heat/cold) can affect outcome regardless of how diligent you are.

Water!

I completed a 23 hour fast, walked almost 20,000 steps and only logged in 615 calories for the day and I gained .9 pounds???

I was 358lbs and I am trying to get to 250. I am now 325.1.

23 hour fast? A physical stressor.
20k steps? Possibly a physical stressor, unless you routinely walk that much.
Only logged 615 calories? Under-fueling, under-nutrition, possibly a physical stressor.

Stress is one of the many different things that can increase water retention, and our bodies can be up to 60%+ water so it's a multi-pound fluctuation.

Also, Riverside is right, as usual: Our bodyweight on any given day isn't the outcome of the day before, it's the outcome of multiple preceding days, in subtle ways. Those outcomes reflect changes in fat, waste in the digestive tract, water retention, several pounds of gut microbes that aren't even genetically "us", etc.

Let's say you lose weight reasonably fast, like the fastest loss rate MFP will let a person request, 2 pounds a week. If the person sticks with that calorie goal faithfully, they'd expect to lose about 4.6 ounces of fat per day, on average.

It's common for people who are not overweight to have water/waste fluctuations from one day to the next of 2-4 pounds or more, even if they weigh themselves under consistent conditions. (I do, at around 134 pounds nowadays in maintenance.)

Someone who weighs more is likely to see bigger fluctuations that are not changes in body fat. If that person is one who has menstrual cycles, the fluctuations are likely to be bigger still. If that person stresses their body - even positive stresses like exercise - the fluctuations are likely to be bigger.

Others are right. If you want to lose a meaningful total amount of weight, that's going to take many months, maybe even more than a year or beyond. That puts a premium on calm, persistent patience, and habits a person can live with reasonably happily for that long a time period.

When you adopt a new routine, plan to follow it for 4-6 weeks (whole menstrual cycles), then evaluate average results over that period, to know how your progress is going.

One day is meaningless, a drop in the ocean. Life is the ocean. It's our routine day in, day out, repetitive habits that are the major factor in our body weight. One day of fasting, one day with 5 hours of workouts, one rare day when we eat 3 slices of cake? Not nearly as important as those everyday habits. Getting stressed out because the scale doesn't reflect the hard work put in the day before? I'm sorry: Not realistic, not helpful.

Focus on routine daily life habits. Make them practical, tolerable, even enjoyable. And be patient. Others have lost as much and more as you're aiming to lose. It can work. Take the long view.

Best wishes, sincerely!

Your body's mad!

You made it work hard with little to no fuel.

Check the oil, fill the radiator, fill with the best gas you can afford if you want your car to last forever.
