What to Eat Before and After Training (Without Overcomplicating It)

Quick answer
Before training (1-3 hours ahead): a meal with carbohydrates for energy and some protein; if short on time, something light and easy to digest (fruit, toast). After: a meal with 20-40 g of protein and carbohydrates to recover, but no rush — the "anabolic window" lasts hours, not 30 minutes. What really matters is your total daily protein and calories, not the exact timing.
Nutrition around training is surrounded by myths inherited from supplement marketing: you have to take your shake within the sacred 30-minute window, you will not perform without a pre-workout. The reality, according to current evidence, is far more relaxed and practical. Here is what to eat before and after without obsessing, and why your overall daily intake matters more than any "timing".
Stop doing the math. Renzy does it for you.

The key idea that saves a lot of stress: peri-workout nutrition is the icing, not the cake. The cake is your total daily calories and protein. If that is right, timing details barely move the needle.
Before training
1-3 h before: normal meal with carbs + protein (rice + chicken + vegetables)
30-60 min before (if short on time): something light and fast — banana, toast, fruit
Avoid right before: very fatty or very fibrous meals (they feel heavy)
Coffee: a great pre-workout ally to perform a bit better

Frequently asked questions
What do I eat before training?▼
If you train 1-3 hours after eating, a normal meal with carbohydrates (rice, potato, bread, fruit) and some protein gives you plenty of energy. If you train on a nearly empty stomach or are short on time, something light and quick to digest 30-60 min before: a banana, toast with honey, or a coffee. Avoid very fatty or very fibrous meals right before — they feel heavy.
Do I have to eat immediately after training?▼
No. The famous "anabolic window" is much wider than was believed: you have several hours, not 30 minutes. If you have eaten protein in the hours before, there is no rush. What matters is that across the day you reach your total protein intake (1.6-2.2 g/kg). An immediate shake is convenient, not essential.
Do I need a post-workout shake?▼
Only if it is convenient or if your next meal is a long way off. A real meal with protein and carbohydrates serves the same purpose. The shake is practical when you train away from home and a meal will take time, but there is nothing magical about it compared to eating chicken with rice a little later.
Is training fasted bad?▼
For gentle or moderate cardio, training fasted is perfectly valid if it suits you and you eat well afterwards. For intense strength sessions or very long workouts, eating something beforehand usually improves performance. It does not burn "more fat" in any meaningful long-term way — what counts is your daily balance.
What do I eat if I train first thing in the morning?▼
You have two valid options: train fasted (with a coffee if you like) and have a good breakfast afterwards, or have something light and quick beforehand (a banana, a piece of toast). Choose based on how you feel training on an empty stomach. Neither is superior; it depends on your tolerance and performance.
