How to lose weight fast using Maths!!

Hi Everyone,

So if you are like me, or in fact any normal human being, you will have at one time or another wanted to lose some weight. How important that is to you will to a large extent depend on just how overweight you believe you are, and what your end goal is.

So you want to lose weight…….then what? How, over what period, in what way? Does this mean you’ve got to go on a diet? And if so which one, there are literally hundreds of them.

Now at this point I’m going to own up to being something of a hypocrite. I have written articles before (see here) where I have attacked diets and said that they don’t work. For me that still holds true. Rather than going ON A DIET I would advocate adopting a long term healthy eating plan that you can maintain AND that also allows you to eat some of the things you enjoy and have a blow out now and then whilst still controlling your weight.

However, that is not to say that you can’t adopt a plan to lose weight when necessary and this article is purely about the mechanics of how to do that. The subject has become almost fiendishly complicated in many peoples minds and my aim is to simplify it as much as possible. Low carb? Low Fat? High Protein? Which is the right path? Most people become so confused and frustrated they just revert back to their normal eating habits and never achieve the results they want.

So lets start with the basics….Calories. You’ve all heard of those right, your dreaded enemy in the battle with the scales. Well not really, a Calorie is just a calorie, it’s neutral. It’s how many and what you do with them that counts.

Calories and what to do with them.

A calorie is simply a measure of energy, heat energy to be precise. Food releases energy as it burns inside the body, so the more calories something contains, the more energy it releases. Body fat is essentially stored energy. So if you don’t use up the energy (Calories) that you eat, your body will store them as fat for future use (or not). Here is the first Maths fact. Each pound of Fat contains 3500 Calories. So in simple terms if you eat 3500 calories more than you use in a week, you will gain roughly a pound of fat.

Essentially you can think of your body as a bank account and Calories as money. If you use/spend the exact amount you put in the account you will remain level. If you put in more than you use your balance will go up (gain fat), and if you use more than you put in your balance will go down (one of the few times its good to spend too much).

To some extent it really is as simple as that. Use more Calories than you eat and you’ll lose weight. From a purely weight loss/gain point of view it also doesn’t really matter where those calories come from ie whether it is healthy or completely unhealthy food, the result will be the same. However not all calories are created equal and clearly from a health, nutritional, muscular, vascular and overall wellbeing perspective its good to eat as healthily as possible and get your calories from good sources.  Don’t just eat rubbish.

So, here is the key part. How do you work out exactly how many calories you use and how many you should be eating to obtain your goals.

This is where it becomes slightly more difficult, but keep reading and I’ll make it as simple as possible. Each persons metabolism (the speed and rate at which it burns calories) will vary slightly and is affected by how much and what type of activity and exercise you do. It also varies slightly from men to women. Roughly speaking however, these figures will work.

First you need to work out your Base Metabolic Rate (BMR). This is the rate that if you laid in bed all day and did very little you would burn calories. Essentially its your maintenance rate each day.

Do this calculation: 66+ (6.3 x your weight in pounds) + (12.9 x height in inches) – (6.8 x age in years). So to use me as an example:  (6.3 x 168lb) + (12.9 x 68) – (6.8 x 48) = 1675. So my BMR is 1675. You then have to factor in just how active you are. Do you sit at a desk all day and do no exercise, or do you work as a labourer and go to the gym?

Sedentary – desk job, very little exercise. Multiply BMR x 1.2

Lightly Active – Workout or do some activity 1-3 days per week. Multiply BMR x 1.325

Moderately Active – workout 3-5 days per week. Multiply BMR x 1.55

Very Active – workout 6-7 days per week. Multiply BMR x 1.725

Extremely Active – workout everyday in addition to a physically demanding job (rare). Multiply BMR x 1.9.

So again using me as an example. I am probably between moderately active as i workout 5 days a week but do a sedentary job, so i took a figure of 1.55. 1675 x 1.55 = 2596.25. So for me my Total daily expenditure of Calories living the lifestyle i do is 2596 per day or 18,173.75 calories a week.

Remember i said earlier that 3500 Calories = 1lb of fat. So very simply if i cut my calories intake by 3500 to 14,673 per week or 2096 per day, then i should lose a pound of fat per week. For most people it is sensible to cut your calorie intake by 15/20% (in my example it was 19%.

It really is as simple as that. Get a calculator, work out what your Base Metabolic rate is. Multiply that (be honest now) by your activity levels, cut 15/20% off of that figure and hey presto you will lose weight.

Of course what that means is that you do need to count calories fairly carefully. Nowadays most things are labelled so it’s not that hard. It also means you are allowed to have some good days and bad days as long as you achieve your overall target each week. It also means that whilst it is best to get your calories from non processed, healthy and natural products ( fish, meat , poultry, vegetables, healthy fats etc), you are allowed to be naughty now and then and hit the ice cream, as long as you meet your weekly target.

Throw in some intensive exercise and you WILL achieve your targets. I’d also add that if you are heavily overweight and you are currently eating way over your total daily calorie expenditure then you will find that if you get your calorie levels to where they should be, then initially at least the 1lb per week barrier is conservative. You may find that for the first few weeks you lose 2lb or even more.

As some of you may have noticed, I’ve kept this on a very simple level. There is a lot more detail to be covered in terms of exactly HOW you should eat and WHAT you should eat. Specifically there is the complex topic of Protein, Fats and Carbs and if you really want to get into some detail, Macro levels and how to eat to build or maintain muscle. However, I’ll do an article on that in the next couple of weeks. For now lets keep it simple.

Work out your daily calorie rate to maintain your current lifestyle and activity levels using the formula I’ve given you. Knock off 15/20%. Eat as healthily as possible, treat yourself now and then (this is Ordinary Guy Fitness after all) and exercise regularly. Follow these simple numbers and the fat loss will come and weight loss will follow.

Confession? Good for the Soul or Your Waistline?

Eating ConfessionsI’m not a religious guy, very far from it. The idea of confessing my sins is not something that really appeals to me, partly because in my case it would just take far too long and partly because the idea of admitting my wrongdoings (real or imagined) to someone else and them judging me for it just doesn’t feel right. However that doesn’t mean that I do no wrong OR that I don’t admit it… myself at least. Today’s blog is a way to confess your sins…..even if only to yourself, that I guarantee will also help you to lose weight and improve your diet and eating habits enormously. What the hell am I talking about? Read on and I’ll explain…

The vast majority of people that I speak to or observe who are trying to get themselves fit, or especially who are trying to trim that waistline and lose weight have one major obstacle, something that catches them out every time. What am I talking about…’s those bad eating or refuelling habits. Even those who are consciously making the effort and really believe they are “eating healthy” are often letting themselves down badly in the kitchen.

Little Sins That Kill Your Wasit line:

The killer is the small things, the little sins that you don’t even think about that ruin all your plans and knock you off track so that losing the weight, reducing fat levels, reducing your waistline and getting fitter becomes a much harder and longer journey than it should. If you’ve read any of my previous posts and even the title of this blog Ordinary Guy Fitness should demonstrate that I’m no evil taskmaster who wants to ruin your life and take away any fun or enjoyment. In fact in a previous post here I talk about how if you are consistent in your training and eating then you can cut yourself some slack now and then and have a blow out. However that doesn’t mean that 5, 6 or 7 days a week you can sneak a little treat or indulgence in and it will go un-noticed.


The fact is that most people, even those trying to be good simply don’t realise how all those tiny little slip ups, or small things that you think “won’t hurt” quickly add up. Let me give you a few examples. Tea and Coffee drinkers, and there are plenty of you, may have 3, 4 or even 5 cups a day. Let’s say you have just over a teaspoon of sugar with each cup….that’s 17 calories per spoon or 85 per day or just under 600 calories per week. In fact drinks are where most people fall down badly eg Fruit juice = average 120-150 calories per 250ml serving. 4 glasses of what you think is healthy fruit juice a week = 1000 calories. A can of soda/fizzy drink eg Coke = approx. 140 calories. It’s late at night, you’ve been good all day, you are watching TV and decide to have a cup of tea and treat yourself to 2 biscuits, “two biscuits can’t hurt right?” Depending on your weapon of choice there are between 60-95 calories per biscuit. Throw in the sugar and milk in the tea and your little pre bed treat just cost you 200 Calories. 5 days a week that’s another 1000 calories added. You’re peckish, you had a really healthy breakfast and lunch but it’s now mid afternoon. You open the fridge and there is a mini pork pie. It’s protein right….can’t be bad for me. It goes down in about 3 bites….another 185 calories. My point is that just in those few examples I have given you that is an extra 2500/3000 calories per week, and that doesn’t count any of the Wednesday night beers or glasses of wine after work which could easily add another 600-1000. That’s a real issue. Here you are trying to be good, watching what you eat, in your meals at least, yet just through small things that you consider insignificant you could be adding anything from 2000 to maybe even 3500/4000 calories a week. Let’s put that in perspective. If you are a lady looking to lose weight you will probably be aiming for a target Calorie intake of between 1400-2000 per day (depending on size and training activity etc). If you are a man it could be 1600-2400. That means that just through the odd little slip up you are eating a whole extra day’s food or maybe even 2. You are consuming 8 or 9 days worth of calories in just 7. How are you going to get a slimmer waistline doing that? Answer….you aren’t!

So here’s what I recommend. It’s a bit of a pain but boy does it work. Keep a food diary. Sounds simple, it is. Get yourself a little waiters pad and initially for a week write down every single little thing that goes in your mouth or down your neck. I do mean EVERYTHING. Every sweet, every spoonful of sugar, every nibble of a biscuit and particularly every single drink. Keep notes. Think of it as confession time. The trick is total honesty. You don’t need to tell anyone else, it can just be your secret, but you really do need to keep a note of every one of your sins. Then at the end of the first week get that pad, set aside an hour and go on google. Try to work out as accurately as possible the amount of calories you have consumed, focus particularly on the drinks, any snacks or anything you just know is probably not good or that is an extra that you could have cut out. I’ll guarantee that you’ll be shocked. Don’t cheat and deny yourself everything just to get a good result. Do what you would normally do and then do the maths. Once you know where all those little extra’s are coming from and more importantly KNOW what they are costing you it will become far far easier to exercise will power. Not only that but just by being conscious of the details and how bad those little inconsequential things can be, you will magically stop wanting them so badly.

So is confession good for the soul? Who knows!! However by acknowledging and then confessing your eating sins, to yourself at least, you will be taking the first and most important steps on the path to righteousness and much more importantly, a smaller waist.

After that first week you may find that you like the habit of keeping a diary. Making the notes and being able to see visually what you are consuming may be what you need to keep you on track. For others just that initial shock will do the trick. Give it a go, even if you are not overweight and just trying to shed a little body fat for summer or to trim an inch off your waistline show off your abs, this trick really works.

HiiT with Weights – My first Video!

Hi Everybody,

I’m a shy retiring kind of guy at heart as my friends will tell you!! However I’m also on a mission to get my message on health, fitness, training and diet to as wide an audience as possible. So as a result I’ve had to bite the bullet and decide to start making YouTube video’s to post both on my website and other social media channels such as Facebook and Twitter etc. Believe me I find it slightly embarrassing at the moment but I guess I’ll get over that in time. Below is my first attempt and if I’m honest there are some mistakes in it. I’m sure I’ll get plenty of stick, especially from my friends, but I really would welcome your comments and thoughts, either on here or on the YouTube channel. If you like it then please like, share, subscribe etc.

HiiT with Weights:

This first video is an HiiT (High Intensity Interval Training) workout but with the added twist of using weights instead of just bodyweight exercises. I’m sure you all know the Body Coach Joe Wickes? He has done a fantastic job of getting the message out there about the positive benefits of HiiT, both in terms of fitness and weight loss or calorie burning. I want to take it up a gear by adding in some additional resistance in the form of weights. This will ensure that you still get that fabulous calorie burning metabolism boost from HiiT but at the same time get a little extra tweak in terms of toning and building some muscle. In this video I’m using 12.5kg/27.5lb dumbbells but you don’t have to do that. Anything from 1kg upwards is fine. This type of exercise would be perfect for all sorts of people from guys into building muscle who don’t want to do long boring cardio sessions on a treadmill or bike, to guys or girls who are looking to torch some fat, fire up their metabolism and tone up their thighs, butts, arms, shoulders and waists at the same time.

Here is the video, i hope you enjoy it and below are brief explanations of all of the exercises.

Dumbbell / Kettlebell Swings x 12: Traditionally this exercise is done with a kettlebell but a dumbbell is fine. Grip it firmly in both hands. Stand in a fairly wide (slightly more than shoulder width) stance. Swing down between your knees and at the same time bend your knees and at the waist slightly. Then swing your arms back up over head height and whilst doing that thrust up and forwards with your hips, concentrating on squeezing with your thighs and Glutes. Continue the same motion for 12 reps.

Shoulder Press x 12: This is pretty straightforward. Grasp both dumbbells firmly in your hands. Hold at shoulder height and push up above your head to full arm extension. Try to concentrate on lifting the weight with your shoulders rather than just using your triceps. The best way to do this is to concentrate on and think about mooving your shoulders up and towards your ears and initiating the movement from there rather than pushing through your elbows.

Goblet Squats x 12: Hold the weight at mid / upper chest level in both hands. Feet should be in a fairly wide (slightly wider than shoulder width) stance. Lower down into a deep squat (as deep as you can go) keeping the weight in front of you at chest level. Push back up by squeezing your thighs and glutes. Repeat 12 times.

Renegade Rows x 12: This is a tough exercise and some ladies unless pretty strong may struggle with it slightly. If that is the case just substitute in standard press ups or even knee press ups. Get down into a standard press up position using the dumbbells to support your weight. Lower down into a press up / push up. When you push back up and reach the top row (or pull up) one of the weights towards your arm pit, then lower back to the floor and repeat on the other side. This works your chest, arms, back and core muscles and will get you blowing.

Alternate Leg Lunges x 12: Most of you will have seen this before. Hold the weights at arm length by your sides. Take a large step forward with one leg and bend down towards the floor until your back knee touches or almost touches the ground. Then push firmly back up with your front leg and move back into a standing position. Then do the same on the other side. Do 12 reps or 6 on each side.

Bicep Curls x 12: This is usually a fairly easy exercise but by now you will be tired and blowing hard. Do not cheat the dumbbells up. Concentrate on keeping your body straight, do not lean back and swing them up. Curl the dumbbell upwards by squeezing your biceps hard.

That’s it. One circuit complete. Aim to do 3-6 sets depending how fit you are. It’s tougher than it looks especially as you start to up the weights. For most ladies I’d suggest starting with 1kg-4kg weights. For guys anything between 5kg and 10kg (unless of course you have been training for a while and are a strong, fit guy). The idea is not to shift massive amounts of weight but to train at high intensity burning lots of calories and firing up your metabolism for hours afterwards, by adding in the weights you will increase the workload and also tone and build muscle at the same time.

So that’s it. My first video. Feel free to poke fun (my friends) or make comments etc. As i said the videos will improve as i go along but it’s the content not the style that I’m more concerned with, after all this is “Ordinary Guy Fitness” and I’ve never claimed to be Stephen Spielberg. Above all I hope you enjoy and if you do then please like the posts, share the posts, comment on the posts and subscribe to my email list , Facebook page or YouTube channel.
