What is the fastest way to lose fat?

There is no shortcut. Set a calorie deficit, hit your protein, track your food, train with progressive overload and judge progress by your weekly average weight. Losing around 0.3-0.7kg per week is a sustainable pace.

Do I need to count calories to lose fat?

You need to be in a calorie deficit, and tracking for at least the first weeks is the most reliable way to know you are in one. After a while, most people can estimate their portions accurately.

What tools do I need to start losing fat?

A scale and an app to track your food and training. Everything else — supplements, gadgets, special foods — is optional.
