When you google “weight loss” the challenge to sort fact from fiction begins.

These five supplements claim to speed up weight loss, but let’s see what the evidence says.

1. Raspberry ketones

Raspberry ketones, sold as weight loss tablets, are chemicals found in red raspberries responsible for that distinct raspberry flavour and smell. You can also make raspberry ketones in a lab.

A study in obese rats found raspberry ketones reduced their total body fat content.

In one study, 70 adults with obesity were put on a weight loss diet and exercise program, and randomised to take a supplement containing either raspberry ketones, or other supplements such as caffeine or garlic, or a placebo.

Sometimes we don’t even believe, that raspberry ketones, for example, will transform our bodies for us, but wouldn’t it be great if they did? It’s a lottery-ticket mentality. In it to win it.
