The question implies that you simply do not want to do anything, but still have a result. This will not work, so medications, if they help, will not be for long.
Losing weight is possible only in the presence of a calorie deficit, and if you overeat and drink vitamins, this will not have an effect. It is best to increase metabolism with the help of physical activity - the greatest response is given by work with iron - an increased metabolism lasts for almost a whole day.
If the metabolism (hereinafter OS) is already good, then you do not need to drink any drugs (it seems logical, but you never know), this will not affect the rate of weight loss.
If there are problems with OM , then, of course, it should be "dispersed" so that the substances entering the body are broken down and used in the form of energy, and not deposited in fat. But, as far as I know (even from personal experience), it is not at all necessary to drink various medicines .. OV is dispersed by ordinary foods and a proper, balanced diet (as well as refusal from laxatives, all kinds of diet pills, hunger strikes and other radical measures, if any ).
Answering the question, good OS helps the process of losing weight go much faster. But this does not mean that if you eat everything and speed up your metabolism, you will lose weight (again, I think this is understandable). Just like with good health, you won't lose 20 kg in 2 days, there is still a certain pace (if you can call it that) of the process of losing weight.
