Overview
What this category covers
This category groups products that are marketed around metabolism, appetite, energy or weight management. They range from powdered drink mixes to a crystal water bottle and a 21-day smoothie plan, so the first thing to understand is what kind of product you are actually looking at.

What to consider
Three things worth knowing before you compare products in this category.
Products here are add-ons, not shortcuts
Weight is shaped mainly by diet, activity, sleep and medical factors. Every product in this category positions itself alongside those basics, and our reviews read them that way.
Be wary of borrowed comparisons
Some sales pages compare themselves to prescription weight-loss medicines or use terms such as GLP-1. A supplement that mentions a medicine is not that medicine.
Match the format to your routine
A daily powder, a water bottle and a structured meal plan ask very different things of you. Choose the one you would realistically keep up for the length of the guarantee.

Questions to ask before you buy
Useful for any product in this category, including ones we haven’t reviewed.
- Does the official page list every ingredient with the amount per serving?
- Are the studies it mentions about this exact product, or about individual ingredients?
- What does a refund actually require: an email, or returning the product?
- Is any package a recurring subscription, and how do you cancel it?
- Could anything in it interact with medication you take? A pharmacist can tell you.
- If it is a meal plan, are you comfortable replacing meals for several weeks?
