Fat

Whether a given overall eating/exercise regimen is working or not is a matter of looking at 4-6 week trend (or at least one menstrual cycle, if a person has them).

Three days is far from enough to know.

Green tea fat burner pills, if that's all you're doing to lose weight, will accomplish pretty much nothing. It's a daydream, fueled by marketers who want you to buy the pills so they can make money, by the influencers who are paid off to claim they work, bolstered by people for whom the placebo effect reduces appetite. (Note: Placebo effect is a real thing, not imaginary. Pick cheap placebos, not expensive ones. 😉)

Science is not on their side. The research suggests that of there is any effect of hyped OTC fat burner pills or supplements, the effect is ultra-tiny at best . . . meaningless to anyone with a fair amount of fat to lose.

To lose weight, we need to eat fewer calories than we burn . . . and we don't just burn calories exercising, we burn them just being alive, doing our jobs and home chores, plus exercise.

If you're eating the right number of calories, you'll lose fat. But you won't see that accurately over a 3-day time period, may even look like you're gaining if you've changed the range of foods you eat, or added new exercise.

Look at that 4-6 week weight trend to know whether you're losing fat.

If what you're doing alongside the green tea pills is so unpleasant that you're hanging on by your fingernails, and that's why you're expecting rewards in a mere 3 days, make an easier plan - one you can stick with long enough to lose a meaningful amount of weight, ideally not being miserable along the way. Misery tends to lead to failure.

I hope you do find something that works - for anyone with a meaningful amount of weight to lose, the rewards are worth the effort!
