The Maths Of Weight Loss & Other Thoughts

I am a mathematician at heart, so after much head scratching I decided to make my first every post about the maths behind losing weight, because that's what we are trying to do here right?

Calories In Minus Calories Out

Now the exact numbers vary depending on whether you are male or female, how old you are, your lifestyle and a dozen other things. But one thing is always the same:

"If you consume less calories than you use each day, on average then you will lose weight."

Now if you are on a serious diet you will need to work out your your maintenance calorie needs, and then factor in your activity levels etc: But that's something for another post, because personally I don't think we necessarily need all of that.

To Lose 1LB You Need To Burn 3,500 Excess Calories

That means that if you want to lose half a stone (8LB) in 2 months, you would need to average a burn of just 250 Calories a day.

The Maths Of Weight Loss

Silly Assumptions

Now we shouldn't make assumptions, but if for a minute we do; let's assume that at present you are neither gaining nor losing weight. Which means that your calories are roughly in balance.

If that is the case, all you need to do is trim those calories by 250 a day, or introduce some exercise to burn them off.

For Example

Now how you do that depends on you, and the rest of this site will soon be brimming over with ideas and tips for dieting, motivation and exercise. For the time being though, let's say you decided to go to the gym 2 times a week, for an hour each.

If you work hard you can easily burn 500 calories in a gym trip, so that's 1,000 calories a week. Then all you need to do on top of that is save another 750 calories - which can be done by cutting out a few deserts or snacks during the week and you can still treat yourself on the weekends.

The take away from this post is that knowing what you need to do, what to expect and having a real plan will make your journey so much easier. It's all about having a realistic vision to keep you motivated.
