When it comes to weight loss or fat loss there is tendency among some of us to view the body in simple terms of calories in vs calories out. “If you want to lose weight - cut your calories”. To a point that is true, and it will work. But at what cost?
Imagine this scenario, you decide it’s time to lose weight so you go on a diet. You have intentions to exercise and decide to join the gym and do cardio for an hour every day. You stick to the plan and weight gradually starts to come off, but then after a while, it stops and no matter what you do the scales don’t budge any further.
Now what? You can’t cut calories further as you’re only on 1200 a day as it is. So you add a bit more exercise – 2 hours walking a day or perhaps an hour on the elliptical thingy at the gym. Yes that’s got it, weight loss again – success. Now let’s fast forward 3 months after the diet is over, what’s happened? The weight is back on plus a little bit more and we’re back to the beginning of the cycle.
Sound familiar? So looking at the above example what is actually happening to your body?
At the start you reduce calories which means your body will burn some of the excess fat it has as fuel. Perfect. However it soon gets used to only having 1200 kcal per day and starts to become more efficient both at rest and during your cardio workouts. You may have heard of something called metabolism, this is the term for all the chemical reactions in your body sometimes referred to as your base metabolic rate or BMR.
Having cut your calorie intake the body also cuts back on some of its energy expenditure, this reduces your metabolism, which at this point isn’t noticeable but as the weight loss slows or stops altogether it becomes very important.
At the end of your diet you may have lost a stone but you’ve also dropped your metabolism through the floor. This is the reason that so many of those that diet and lose weight will also put it back on again a few months after dieting.
What can we do about it?
There are certain things that affect your metabolism that you can’t change such as gender, genetics and age. But there are some ways we can increase your metabolism. Here are a few.
1. Eat plenty of protein with every meal – protein takes more energy for your body to break down and so increases your BMR.
2. Train with heavy weights – Training with weights has been proven to increase your metabolism way after the session has ended. But train heavy or there is little to be gained.
3. Do HIIT training - similar to the above HIIT training has been proven to increase metabolism way after the session has finished. The key word however is intensity. Pick 3 or 4 big exercises and create a circuit. 40 seconds of each exercise then 40 seconds rest. Repeat 8 times.
4. Eat plenty of veg – vegetables contain fibre, and fibres need higher amounts of enzymes to process. This increases metabolism.
5. Don’t eat processed food. – Its crap and bad for you and does nothing to help with metabolism. In fact it slows it down.
6. Drink green tea – or take green tea supplements as the antioxidants in green tea have been proven to raise energy expenditure and promote fat loss.
Calories are important but without some attention to your metabolism your effort and determination may be in vain.
