How I Figure Out My Calories (Without Overthinking It)
A gentle note: This article is general education for adults (18+), not medical advice, and results vary. Eating eggs daily isn't for everyone, so check with your doctor if you have a health condition. Full disclaimer.
You don't need a lab test or a fancy app to set your calories. I use a simple, bodyweight-based starting point for each phase, then let the scale tell me whether to adjust. Here's the thinking behind it.
The basic idea
Your body weight changes based on energy in versus energy out. Eat a bit less than you burn and you lose weight over time; eat a bit more and you gain. A classic rule of thumb is that about 3,500 kcal is roughly a pound of body fat, but it's approximate: real-world loss usually slows as you get lighter, and water weight hides fat loss week to week.
So the goal isn't a perfect number on day one. It's a sensible starting point you can adjust.
Start from your bodyweight and your phase
Bigger, more active people burn more, so a bodyweight-based starting point is a simple, reasonable way to estimate your needs. My method uses a different starting point for each phase:
- Fat Loss: a modest deficit.
- Maintain: roughly what you burn.
- Lean Bulk: a small, fixed surplus, not "eat everything."
- Recomp: maintenance-level eating, with a little more on training days.
It's the same approach I use. I lift Monday, Wednesday and Friday, then do boxing or cardio, and my numbers account for that.
Protein matters
Higher protein helps keep muscle while you lose fat, supports training, and helps you feel full. That's a big reason my routine is built around eggs: they're an easy, affordable way to get a lot of protein in.
Your day job counts
It's not just the gym. Being on your feet all day burns real energy, and that varies a lot from person to person. If you're maintaining or bulking and keep losing weight, you probably need more food. If you're losing fat, extra activity just helps.
Check the trend, then adjust
Numbers are estimates. Stick with your starting point for 3-4 weeks and watch your weekly average weight, not single weigh-ins.
- If you're losing faster than you want, or you're always exhausted, eat a bit more.
- If nothing has moved after a few honest weeks, look at your portions and extras first, then trim a little.
Don't go too low
Very low calorie intakes aren't a good idea without medical supervision. My method has built-in minimums, and if you're smaller or lighter, a quick chat with your doctor is worth it.
Common mistakes
- Not counting add-ins. Butter, cheese and sauces add up.
- Eating back every calorie your watch says you burned. Fitness trackers are estimates.
- Changing everything after one bad weigh-in. Water swings are normal.
- Never recalculating. As your weight changes, so do your needs.
