The Busy Professional's Fat Loss Kit (free)

Two things my clients use the most. The calculator result shows right here on the page, the playbook is a PDF.

Your download link and your numbers appear right here after you click. Your data: Martin Barna (Czech business ID 76383032) stores your name and email, and your calorie and protein result if you used the calculator, only to send you the kit and the emails, until you unsubscribe or after 3 years without activity. Details in the Privacy Policy.

What's inside

1Calorie and protein calculator

Your daily kcal (calories) for your goal and a protein target in grams. The same calculation I use with my clients as a starting point. 30 seconds, result on this page, no email needed.

2The Eating Out Playbook (PDF)

How to order in 8 types of places: steakhouse, Italian, Asian, burger, hotel breakfast, airport, corporate dinner, bar. For each one 3 better choices and 2 traps, with rough kcal. Plus the minimum version for travel days and alcohol in numbers.

Your calories and protein

Fill in 6 fields. The result is a starting point; in coaching I adjust it every week from your real data.

The formula differs by about 160 kcal between the two. Pick the one closer to your body.

Your starting numbers

- kcal a day

- g protein a day

Not medical advice. These numbers come from a standard formula (Mifflin-St Jeor) and are a starting point, not a diagnosis or a treatment plan. If you are pregnant or breastfeeding, have or had an eating disorder, take medication that affects weight or appetite, or have a medical condition, talk to your doctor before you change how you eat. This tool is for adults (18+).

Who is writing this

Martin Barna, nutrition and fitness coach from Ostrava, Czech Republic. In the field professionally since 2013: 13 years of nutrition practice and 600+ clients.

Guest on Czech national TV (ČT). 5.0 average from 100+ reviews on Google and Facebook.

International trainer certification, nutrition advisor certification, advanced coaching studies.

I coach online and mostly in writing. My clients are busy adults: parents, managers, people who travel for work. You learn to eat normal food in the right amounts instead of getting a meal plan for the drawer, so the result stays when we finish. Diet does about 80 % of the result; steps, some strength training and sleep do the rest.

How the coaching works (everything in writing)

One program for English-speaking clients: the same weekly system my Czech clients use, in writing. I take a limited number of clients so I can read every report properly.

1

You apply in writing

Fill in the form below. I usually reply within 24 hours on working days with a few questions, and we see if it's a fit.

2

You get your plan

After payment you fill in an intake questionnaire. Within 48 hours you have your calories, protein and macros, a meal plan built around the way you actually eat (restaurants included) and a training plan for your real schedule.

3

Weekly report, 3 minutes from your phone

Weight, waist, food, steps, training, how the week went. I answer in writing with the plan for the next week and recalculate your numbers. Every week, as long as we work together.

4

WhatsApp between the reports

Monday to Friday for everything in between: a menu before a dinner, a hotel breakfast, a week that fell apart. I answer within 24 hours (time zones). Plus one short educational guide every week: portions without a scale, plateaus, eating out, sleep.

  • Calories and macros set for you and recalculated every week from your report
  • Weekly report and my written answer with the plan for next week
  • WhatsApp Monday to Friday, answer within 24 hours
  • A plan for eating out and travel, built into your week
  • The minimum version for messy weeks, agreed in advance
  • One educational guide (PDF) every week

No video calls. You get every plan and every number in writing, and you can read it again on the plane.

Is this for you

This is for you if:

  • You want to lose 5 to 20 kg, mostly the belly, and keep it off.
  • You eat out 2 or more times a week, travel, or work 10 hour days.
  • Your diets so far worked until the first business dinner.
  • You want a plan built on your real week and someone who checks it every 7 days.
  • You can write a 3 minute report once a week and log your food, at least roughly.

This is not for you if:

  • You want 10 kg gone in 3 weeks. Realistic is 0.5 to 1 % of body weight a week, so 0.5 to 1 kg a week if you weigh 100 kg.
  • You want a fixed meal plan to follow without thinking. You'll learn to decide for yourself; that's the whole point.
  • You don't want to write anything down, not even a rough guess. Then I have nothing to adjust.
  • You are pregnant or breastfeeding, have an eating disorder, take medication that affects weight, or have a medical condition. Talk to your doctor first. I'm a coach, not a doctor.
  • You are under 18.

Questions I get

I'm in the US, UK or Australia. Does the time difference matter?

I'm in Czechia (Central European Time). You write when it suits you, and I usually answer within 24 hours on working days. Nothing in this coaching needs us online at the same time.

I eat out 3 or 4 times a week. Does this work?

That's where most of the work is, and where most diets break. We build the plan around your dinners instead of against them: protein and vegetables first, one portion of carbs, sauces on the side, drinks in the budget. The playbook is the short version. In coaching you can send me a menu a day ahead on WhatsApp and I mark what to take.

What about alcohol?

You can drink. Alcohol = 7 kcal per gram. A small glass of wine (150 ml) is roughly 120 to 130 kcal, a large restaurant pour 150 to 220, a pint of beer 200 to 250, a cocktail 200 to 500 (a creamy one is the top of that). We put it in the weekly numbers. One more thing from the studies: in studies on younger adults, people ate on average about 80 kcal more food after drinking and did not eat less later to make up for it. In a bar with snacks it is often more. So we plan the food around the drinks too.

I have no time for the gym.

Diet does about 80 % of the result. For the rest: 8,000 steps a day and two short strength sessions a week, at home or in a hotel room, 20 to 30 minutes. If you have a gym and like it, we use it. If you don't, we don't.

How fast will I lose weight?

A realistic pace is 0.5 to 1 % of body weight a week, so 0.5 to 1 kg a week if you weigh 100 kg. 10 kg = roughly 3 to 5 months. Faster is possible on paper and usually costs muscle, energy and the result itself a few months later. The scale also jumps 1 to 2 kg with water and salt, so we watch the trend and the waist, not one morning.

Why no calls?

Everything is in writing, so you have every plan, every number and every answer in one place, and you can read it again on the plane. Second reason, an honest one: my English is better on paper than on a call, and I'd rather give you a precise answer than a fast one. Want more support? Message me for VIP options.

What happens after I apply?

I usually reply within 24 hours on working days with a few questions. If it's a fit, you pay by card, fill in the intake questionnaire, and within 48 hours you have your calories, protein, meal plan and training plan. Then your first weekly report.

How much does it cost?

The current price is in the coaching section above: monthly, or 12 weeks paid upfront for less. You only pay after I've answered your application and we both agree it's a fit. Payment is by card.

What if it's not for me?

You have a 14-day money-back guarantee. If you change your mind within 14 days of paying, email martin@martinbarna.cz and you get the full amount back. No reason needed.
