executive coach bangkok thailandJohn, a client of mine, made tremendous progress over the last few months. Compared to five months ago when we started working together, he is now a different person. You can see it. “I am a thousand times more relaxed these days, and my team has improved performance”, says John confidently.

“What’s the key to your success?” I asked. “Two things”, John replied, “one was to start the executive coaching with you. Coaching helped me to adopt a much more effective leadership and management style. I am more grounded, and the guys can’t get me out of balance anymore. In addition, my staff shows more initiative, and last week, after our team retreat, they said it was the best meeting we ever had!”

“The other thing was to start exercising regularly and changing my nutrition.” John obviously lost a couple of excess kilos. He looks healthier and much more fit today. “Overall, I feel much more energized these days. Normally at this time of the day [it was 4 p.m.] I would be tired already. Now I enjoy pushing it for a couple of more hours,” he declares with a big smile.

I was glad and impressed to witness the tremendous improvement John made in such a short time. Seeing him so much more energetic and confident lead me to two crucial questions:

In order to improve leadership quality, do we need a more holistic coaching approach which covers nutrition and exercising?


Would adjusting my own nutrition and a different exercising routine improve my energy level and performance, too, although I pursue a quite healthy lifestyle already?

The latter question lead me to a self-experiment in which indeed I changed my eating and exercising habits. Six weeks into the trial, my answer is a clear “YES” to both questions!

Here’s what I did wrong in the past, what I changed, and what results I achieved. See what applies to you; you may find the missing links to improve your own leadership performance – and your quality of life!

What I Did (Wrong):

I thought my lifestyle was quite healthy. I favored a vegetarian diet, and I had fresh fruits and  vegetables regularly. Believing that fats make fat I avoided them, particularly the unsaturated ones (e.g. butter). I practiced Yoga  asanas (poses) regularly, and I went to the gym for some cardio exercise and workouts with the “machines”.

How wrong was my approach to a supposedly healthy life! I was not aware I was making  these major mistakes:

  • I ate too many carbohydrates and not enough proteins
  • I ate too many “bad” carbohydrates (bread (Germans’ favorite!), pasta, hidden sugars)
  • Although I exercised regularly, my exercising routine was simply not effective (see below)

What I Changed:

Triggered by John’s positive experience I visited Randall Hatfield from Aspire Fitcorp Asia. Coincidently a “28 Days Body Transformation Challenge” consisting of nutrition talks and group exercises started 2 days later, and that was just ideal for my self-experiment. I signed up.

In addition, I invited my friend Thomas Ehle for lunch. Thomas is a fitness enthusiast, a nutrition expert, and the author of “Easy Body Up-Grade”. He challenged me on my carbohydrate intake and suggested to leave bread and muesli aside for a couple of weeks and to see what happens.

So I did.

  • for 4 weeks, 4-5 times/week I did a high intensity interval training (much to my surprise the actual activity phase was sometimes as short as 15 minutes only!)
  • in week 4 I added some basic strengths training
  • I reduced all “bad” carbohydrates to almost zero (bread, pasta, pizza, refined sugars)
  • I started eating proteins like crazy (eggs, meat, fish… very much in contrast to my vegetarian preference)

What I Achieved in Less Than 6 Weeks:

Ok, I am not going to post before-after pictures here. But trust me, only 6 weeks down the road it’s still hard for me to believe how much my body has changed in a ridiculously short time with much less effort than I had expected!

  • in less than 4 weeks I reduced 2.3 kg fat and gained 1.7 kg of muscles
  • I feel stronger and more energetic
  • I don’t have any cravings for chocolate or ice-cream anymore (which I encountered quite regularly before)

It’s somewhat embarrassing to realize that I thought my life-style was quite healthy, but in fact in many ways it wasn’t. What I believed I knew about healthy food and effective physical exercise were to a great extent either just myths or nowadays outdated knowledge.

You may have heard (and believed) similar myths:

  • Regular jogging at moderate speed for a minimum of 30 minutes is great for your health. It prevents heart diseases and is ideal for fat loss.
  • Moderate exercise is better than exhausting yourself.
  • Lifting heavy weights harms your joints. Using expensive machines in expensive gyms is better.
  • Fats make fat.
  • Your brain needs “sugar” to function well.
  • If you are German: bread is what you just have for breakfast and dinner, no questions asked.


Excuse me but that’s what it is.

What You Must Do

Ok, no musts here. But a couple of shoulds:

If any of these myths above sounds familiar to you, too, it’s time to question your eating habits and exercising routine!

Of course there is not the ideal nutrition, the one size fits all approach. What turns out great in one study may be considered bad in another. However, it is worth reading some recent studies. Be aware of who sponsored the study and choose what you consider credible sources. Then try a few approaches over a couple of weeks, and finally let your body decide what is right for you.

If you don’t exercise, start moving your body. If you exercise, make sure you exercise effectively. Generally exercising may be better than no exercising, but wrong exercise will in best case be a waste of time. Worst case it will cause you harm.

It’s worth spending some time on a more holistic approach in order to improve performance at work. Achievement is not just about working hard or smart. Whilst executive coaching and other personal development activities may help improve your leadership and management skills, you will never achieve your full potential if you do not take care of your physical body. And this requires some basic understanding and experimenting with your diet and workouts.

I strongly encourage you to do some self-experiments! (Disclaimer: consult your physician first blabla…) I look forward to hearing about the positive changes you will experience. Meanwhile, I will continue my own experiment. Looking at the results after merely 6 weeks, I am curious what I will achieve over the next 6 months.

7 Responses to The Missing Link(s) to Optimum Leadership Performance

  1. There were a couple of great comments on my Facebook page which I think are worth re-posting here to make them available to a broader audience:

  2. “Very interesting. The last few days I’ve also come to realize that my sluggishness came from eating too much bread. I’m also experimenting with a few weeks without it and yesterday I was productive from 4:30am until 6pm with just 2×20 minute naps. I’m reading rich roll’s book ‘finding ultra’ which recommends veganism. I am thinking to try it for a month to see how it affects my running.” -M.P.

    Indeed it’s all about trying new things, and that’s part of the fun in life, isn’t it?

    I am curious to hear how your vegetarian diet will turn out!


Btw, a funny side effect I observed regarding running: I didn’t do any running for more than 6 weeks. Then last week I went for a run without any preparation but the interval training – and reduced my lap time significantly!

  3. “Glad it is working for you. I have two comments. Animal proteins have been shown in many research projects to cause cancer. Long term health needs to be balanced against what makes us feel good short term. The best exercise is the one you will keep doing for the rest of your life and not give up after a few weeks because it does not fit in with your lifestyle. I do agree that people are wrong to cut fat out of the diet. Good luck with your project.” -H.K.

    1) I am aware of some studies that indicate particularly red meat as a potential cause of cancer.

    The confusing thing with all studies I have seen on the highly complex field of nutrition is that what turns out great in one study is considered harmful in another. (Just for the fun of it do some research on coffee. From what I have seen the benefits seem to equal the risks. I still love coffee, and I respect anyone avoiding coffee for health reasons.)

    For any study, I first of all recommend reading the original study, not some summary or comment in e.g. a magazine. Then look at the test conditions precisely. Look also at who sponsored the study…

    As for the meat: I’d love to avoid animal products for ethical reasons. However, for seven years I did not find a vegetarian diet that suited me well. I am open to suggestions.

    2) I respectfully disagree with a generalization like “the best exercise is the one you will keep doing because of your lifestyle.” I see too many people exercising in a way that does not help them achieve the results they desire. In my opinion the best exercise is the one that really benefits you. If this results in a significant improvement of your quality of life, won’t you eventually adjust your lifestyle?

    Dieting is fascinating because despite there being so many contradictory diets, all have a wealth of advocates and critics.

    One ‘experiment’ you might be interested in is to get your DNA analyzed. This is something that a few years ago cost $1,000+ and every few months the price has been dropping like crazy. Take a look at 23andme.com for a complete DNA test for a 1-time $100 cost.

    I just treated myself to this. It’ll tell you your secretor type (which combined with your blood type may help you to determine the optimal diet for you – see the book ‘eat right for your type’).

    It tests for your responsiveness to certain substances like gluten, caffeine and alcohol, tests whether you are a responder to exercise etc. and gives you a lot of details about your current health and potential health problems in the future.

    BTW – I’m not affiliated with the company, but I am excited about it :)

    • Hi Martin,

      Indeed all the controversy may be confusing, and at the same time that’s the beauty in it.

      Never heard of this DNA test and sounds interesting; thanks for sharing.

      However, I am already quite aware of how I respond to certain substances like caffeine: today a Starbucks coffee dramatically reduced my suffering from jetlag :-)

      (Oh, I am not affiliated with this company either…)
