Getting lean and jumping higher by tracking every calorie

Back in October my rec league basketball team lost back to back games in OT by 1 point. I decided I wanted to make a more serious effort on my conditioning to win more games.

At the time I felt like I was working out hard and eating clean but it was clear my progress was stalling.

I decided it was time to start tracking calories in and out as accurately as possible and see where it took me.

The 3-month keto experiment

I’d never gone low-carb before, but the recent carnivore hype all over my feed sounded appealing. I've always loved eating a lot of meat.

• Macros: ≤ 50 g carbs, ≥ 200 g protein, the rest fat.
• Why it worked: two high-protein meals kept me full on ~2,500 kcal. Basketball performance was unaffected.
• Why I stopped: brutal leg cramps after a morning of toddler snowman building plus an afternoon on the ski slopes. Energy levels after basketball were consistently low.

Flipping the macros (carbs up, fat down)

The fix was obvious: carb-up on heavy exercise days, slash fat to keep calories in check.

• Protein never changed, still a 200 g floor.
• Lean staples
  • 85/15 ground beef (1-2 pounds daily. Yes, really)
  • Chicken breast or thighs, salmon, tilapia (~300g cooked portions)
• Foods I love but stopped eating
  • Bacon & most pork cuts (only toddler leftovers)
  • Cheese
  • Nuts and peanut butter

What actually stayed on my plate

Never worth it (for me): pastries, sugary drinks, peanut butter, and any recipe so complicated I easily can’t weigh the parts.

How I actually tracked everything

• Kitchen scale on the counter every bottle of olive oil gets weighed before & after a pour.
• Repeat meals breakfast and lunch hardly changed for 100 days; MyFitnessPal logging became two taps.
• Same time weigh ins same moment of each morning routine; reduces water-weight noise.
• Dashboard Apple Watch + MyFitnessPal iOS widgets on a home screen that show a snapshot of my daily calories in and out.

What the data taught me

• Apple Watch burn is close, but not exact. First month it under-shot, later it drifted over by ~8 %. Weekly averages are fine; single-day numbers are noise.
• Resting burn decreased by ~200 calories as my weight declined (2,500 → 2,300) as the weight came off. Your metabolism absolutely adapts to the fat loss.
• Big deficits get harder the leaner you get. At 20% BF I could manage to sleep with a 1,000 kcal deficit; by ~15% BF anything more than −500 was difficult.
• Cumulative deficit vs. scale line tracked very closely, proof the boring math still wins.

Results

I didn’t log exact performance numbers, but here’s the practical outcome:

• Deadlift, squat, bench never dipped (protein saturation worked).
• Consistent one-hand and two-hand dunks achieved as I got to 210 lbs.
• Achieved visible abs for the first time in my life.

Two things I’d highly recommend if you try this

1. Weigh your food every time. Simplify recipes until you can weigh them; uncertainty kills results.
2. Surface the numbers. Wear an activity tracker, export the data, and look at deficit vs. scale every single day. Progress will keep you motivated.
