These two categories are frequently shelved together and they are not solving the same problem at all.

How fat blockers work
Lipase inhibitors reduce the absorption of dietary fat in the gut so a portion passes through undigested. Orlistat is the pharmaceutical version with genuine trial evidence; over-the-counter versions using chitosan have considerably weaker support. The mechanism is absorption, not metabolism.
The side effect problem
Blocking fat absorption produces exactly the gastrointestinal consequences you would expect, particularly after a high-fat meal, and it can reduce absorption of fat-soluble vitamins over time. These are not rare footnotes — they are the primary reason people discontinue.

Get SodaSlim — From $49How the mechanisms differ
SodaSlim does not block absorption. It raises expenditure, moderates glucose absorption and supports satiety. Green coffee's chlorogenic acid affects carbohydrate rather than fat handling. These are complementary rather than competing approaches, though stacking them is not something to do without medical advice.
Which suits which problem
If your diet is high in fat and you want an absorption intervention, that is a different category and a conversation with a doctor. If your problem is expenditure, cravings and energy, a thermogenic like SodaSlim is addressing the relevant levers.
