Can you gain strength with intermittent fasting?


If you find the title of this column interesting then probably you already have some experience with intermittent fasting, or you know about it and want to try it. Intermittent fasting (IF) has become very popular in the last few years. You may have heard some amazing success stories but maybe also some not so positive results as well. 

Most of us are looking for an easy way to lose fat and gain muscle and strength, and IF can be a very beneficial tool for many people. Especially when you consider that we are all surrounded by lots of fast foods, ultra processed foods, and almost every social event involves some type of food. I actually find that many of my clients prefer time restricted eating and find it easier than eating whenever they want but with a calorie restriction. Some studies do support that IF can be very beneficial, especially for people who struggle to stick to their diet seven days a week, or for people who are type 2 diabetic. Of course you should be very careful as to whether this approach fits your lifestyle or not, because if not then you may see more damage than benefits. 

There are many ways to apply IF, including 14-10, 16-8, and 18-6. These refer to the hours in the day — for example, 14-10 means that you fast (don’t consume anything) for 14 hours and consume all of your calories (solids and liquid) within a 10 hour timeframe. In 18-6 you’re only eating within a 6 hour timeframe each day, for the remaining 18 hours you’re fasting. 

There are however a couple of other very effective and popular strategies — 5:2 and alternate day fasting. You may find it easy to do a 5:2 fasting approach, which means that each week on two days of your choice you consume only 500 to 750 calories a day, but on the remaining five days you eat normally. Some people find this much more manageable than trying to eat less calories all the time, and it can also be very beneficial for blood glucose (sugar) control and can even help reduce your hunger on the following days too. Although eating under your maintenance calorie level is probably not optimal if your goal is hypertrophy (muscle gain), when you combine it with resistance training and an adequate protein intake this will improve your body composition and your strength. 

IF is not necessarily a better choice than a calorie restricted diet, just some people do find it much easier to control their hunger and can therefore stay longer on their diet. However, if your goal is to gain muscle then you need to make sure you are getting enough protein and calories on your non-fasting days. And, of course, you need to do some type of resistance training to support your goal. 

I think many people are successful on a 5:2 or other IF approach because of its simplicity. Just do make sure that this approach fits in with your lifestyle, and especially if you have a history of any type of eating disorder then it can be a very bad idea to try for you. 

Remember, all of the IF strategies ultimately come down to some type of calorie restriction. So even if you are practicing IF regularly, but consuming too many calories in your non-fasting hours or on your non-fasting days, it will not be beneficial from a weight loss perspective — although weight loss is of course only one part of the many benefits of fasting. 

Before you start any type of diet, ask yourself “Can I add this into my lifestyle for at least 3 to 6 months?”. As always, if you have any current medical concerns please ask your physician before trying any of the intermittent fasting approaches.

You’ve probably heard so many people say “I love what I do”, BUT in my case I can truly say it from my heart. I’ve competed in sports all my life, but it wasn’t so long ago that I really understood that actually I can only ever compete with myself.

“You are perfect, until compare yourself with someone else”

I started contest prep in 2011, and since then I didn’t stop competing. In some competitions I got first place, in some it went not so well, but every competition that I prepared for taught me something more about myself and helped me take the correct direction, which I believe has shaped my work and my life in such a positive way.

When I competed in my first bikini competition I had just moved from my home country Turkey to Canada, and was getting used to the Canadian lifestyle — and, of course, the language too, which was the hardest part for me. I always wanted to do a fitness or bikini competition, but when I was still in Turkey the work and cultural differences made it so hard to do.

So I was in Vancouver BC, working at Steve Nash Fitness Club, and one of my co-workers, who was a competitor herself, asked me “why you are not competing?” I started asking myself and questioning if I could do it? I’d never done anything like it before… Maybe you’re asking yourself the same questions right now! Of course I told myself “absolutely, I can’’. And my competition journey began!

Each show that I competed in gave me more knowledge about my body, and how I can improve. Of course, it’s not easy to correctly identify what’s missing with training and nutrition, and this learning process and all of the experiences pushed me to learn more… I’ve been a personal trainer since 1993, but I wanted more and began my nutrition studies. I finished my Comprehensive Nutrition and Sports Nutrition degrees.

And yes, I am still competing! You can see a list of all of the competitions that I’ve competed in further down this page. And right now, AGAIN, I am getting ready for my next show…!

I’ll warn you right now, it wasn’t easy at all. The easiest part was the training, which was already part of my daily life. But posing, dieting, supplementation, getting a bikini, finding a trainer… This was much tougher, not the mention the cost for the registration, jewelry, tanning, hair and make-up, they cost a lot too. 

But I wouldn’t let anything stop me, and right after my first show — WBFF in May, 2011 — I immediately started looking for the next show to compete in. I was hooked!

I am so happy to be able to help other competitors who are willing to work and improve their mind and health at the same time. My goal is to create healthy and happy bikini competitors, who want to challenge themselves and put in the work that needs to be done to reach their goals. There is really no easy way to get there… But there is a smart way.

I look forward to working together and sharing my knowledge with YOU to get you in the best shape of your LIFE!!!!!
