A calorie deficit means eating fewer calories than your body burns daily. A 500 calorie deficit leads to approximately 0.5kg (1lb) of fat loss per week. This is the only scientifically proven way to lose body fat.
Quick answer: A 500 calorie deficit per day is optimal for losing ~0.5kg/week of fat while preserving muscle. Keep protein high (2.0-2.2g/kg) and don’t reduce training intensity.
Find out how many calories to eat to lose fat at the optimal rate.
A calorie deficit means eating fewer calories than you burn (TDEE). This forces your body to use energy reserves (fat) to make up the difference.
I was looking for exactly this. Thanks for the breakdown.
Great content. How would you adjust this for a 4-day split?
Solid routine! Does this work well for natural athletes?

Yeah that’s basically it, just a little oversimplified.
A calorie deficit is the driver of fat loss no way around that. If you consistently eat fewer calories than you burn , your body has to pull energy from stored tissue, which is mostly fat.
The whole “500 calorie deficit = 1 lb per week” thing is more of a guideline, not a guarantee. Some weeks you’ll lose more, some less. Water weight, stress, sleep, all that stuff can mess with the scale.
Also, 500 isn’t magic. It’s just a solid middle ground where you can lose at a decent pace without feeling like trash or risking muscle loss.
You’re spot on about protein and training though. Keeping protein high and lifting heavy is what tells your body “hey, keep this muscle.”
So yeah, calorie deficit is the foundation, everything else just helps you do it better and stick with it.
