Skinny Not difficult

It’s becoming a speciality of mine to take 50-something kilo men and getting them to a ‘normal’ weight for their height, with a lot of that mass coming in the form of muscle!

These guys often get a bad rap for being a ‘bad’ or ‘difficult’ client but I don’t feel this is the case if you adopt a few sensible strategies.

Here are some of the mistakes I see other Personal Trainers making:

  • Making extreme changes to their diet


  • Not looking at the person’s physiology before selecting exercises
  • Not taking psychology into account

How can we address this?

Today I’ll cover the first bullet point.

Making Extreme Changes to Their Diet Becomes Make Small Changes Over the Long Term

If someone is underweight you know they under eat.

This doesn’t mean they suddenly need to double their calorific intake because they are going to hate it and probably just feel fat and bloated.

You need to make gradual changes to keep the person as comfortable as possible but still in a calorific surplus or calories in > calories out most of the time.

In order to do this, I’ll usually start by asking where the client feels they should or could eat a little bit more.

With some people, they’ll forget to eat breakfast (but it could be any other traditional mealtime) every day because they tend to be people who’ll skip meals at the drop of a hat because…well, it’s what they’ve always done hence their skinny frame.

  • If they tell me they always miss breakfast, I’ll get them to try and eat breakfast 3 times a week for a couple of weeks.
  • If they manage that then you can increase that by one day a week until they are eating breakfast every day.

By doing this they are increasing their calorific intake by a couple of thousand calories a week without making much of a change to their lifestyle.

Some people just won’t eat breakfast (or another meal during the day.)

that’s fine

You just need to adopt some of the other strategies we’ll talk about in the remainder of this article in order for this not to be a problem.

Another common theme I’ve seen (with my client Matt James for example) is just forgetting to eat on days off or when in the house.

If anyone is going to skip a meal it is someone preoccupied by computer games or hacking or forums or geek places that are unknown to me.

Many skinny guys do this!

These distractions get in the way of hunger signals and rather than telling someone to ‘stop with all the computer shit and eat’ you are going to have much more success looking for the days they eat the least and improving on those.

With Matt James, his problem was not eating on a weekend.

Just forgetting to eat!

Having all the intention in the world but getting to the end of the day or realising the next day that

“oh shit, I didn’t eat!”

Together we came up with the action plan of eating 3 meals a day on both weekend days.

Other issues Matt and I came up against –

  • at work food often wasn’t to hand or
  • he’d forget to prep or
  • not want to prep or
  • forgot to buy food so he’d end up not eating.

I’m not sure these issues are fully resolved yet with Matt but often a good solution is to get a protein shake that doesn’t make the person feel ill to keep at work (maybe in combination with some ground oats) that the person can have immediately without having to interrupt his work too much.

It’s not ideal.

We’d love all the food to actually need chewing but having the 200-400 calories rather than nothing a couple of days a week might be the thing that gets them over 60kg and feeling strong for the first time in their life.

Another recent success I’ve had with other guys who can’t stomach protein shakes or just don’t like them is having a box of Grenade Carb Killas or Quest Bars at work so they can snack on those as often as is required.

Matt’s work resulted in these changes:

Pretty good going!


Another client who started being far too skinny for his liking is a guy called Ian Redfern.

We started with a similar process to Matt by looking at areas where he was under eating and it got to a point where we just had to look at foods that he could eat a lot of.

In Ian’s case it is tuna and pasta.

He can eat a ton of the stuff so he does just that!

The combination of eating plus his muscle building training plan has resulted in the following changes:

Ian started training earlier than this so his increase in weight has been even more dramatic than this appears.

He is now large and in charge.

I’m so proud to call them both my clients.

When training a skinny guy, you can run into problems with eating speed or just the person finding it extremely uncomfortable eating very large quantities of food.

This sucks for the person but the solution lies in eating very calorie dense foods so the stomach isn’t stretched to the point of discomfort.

Some of the best calorie dense foods are:

  • Chocolate Milk
  • Ice Cream
  • Peanut Butter
  • Avocados
  • Pizza!

Recently I’ve had a few skinny guys come to me who are already tracking their food on Myfitness pal.

Two of the best places to look for further information on successful macro tracking are Gains Glutes & Glitter and here on Propane Fitness.

Getting the most out of calorie tracking is a must if you are to make it work for you. These two sites will help you do just that.


How can you make skinny guys not so skinny anymore?

  • Increase meal frequency on days where they don’t eat
  • Place meals where they’d normally forget to eat
  • Have emergency food stores at work or somewhere where a lack of food prep could be an issue
  • Increase the quantities of foods that the person actually likes and can tolerate in larger amounts
  • Have calorie dense foods

Put these strategies into place and as long as they are turning up you’ll make progress eventually.

Keep looking for easy ways to help them increase their calories and hopefully they’ll begin putting on weight.

Remember you aren’t a psychologist so if you suspect any kind of eating disorder you simply have to refer them to a qualified professional or you risk making their condition worse.
