Thanks for the question … if you mean, from hour to hour, don’t weigh that often, it’s just noise. Your weight fluctuates with your hydration and digestive contents too much to make much use of that data.
If you mean from day to day, your weight loss will be spiky up and down, not a smooth curve, it just is.
If you mean from week to week for several weeks, check your compliance to your program. And if you have no program, there’s your problem, pick some plan and go for it for 2-3 months minimum.
Losing weight is going to take some time. Stay right with your program, eat the right amount of the right kinds of foods, and move your body as best you’re able to, and you’ll have good results.
