James Smith Deficit Calculator


James Smith Deficit Calculator is a tool used to determine the difference between the amount of calories consumed and the amount of calories burned in a day. It is an essential tool for individuals who want to lose weight or maintain a healthy weight by tracking their calorie intake and expenditure. In this essay, we will explore the concept of the deficit calculator, its benefits, and how to use it effectively.

Firstly, it is important to understand the concept of a calorie deficit. A calorie deficit occurs when an individual consumes fewer calories than their body needs to maintain its current weight. This deficit forces the body to burn stored fat for energy, resulting in weight loss. On the other hand, a calorie surplus occurs when an individual consumes more calories than their body needs, resulting in weight gain.

A deficit calculator helps individuals determine the amount of calories they need to consume each day to achieve their weight loss goals. To use the calculator, individuals need to provide information such as their age, gender, height, weight, and activity level. The james smith kcal calculator then uses this information to determine the individual’s basal metabolic rate (BMR), which is the amount of calories their body burns at rest. The james smith academy tdee calculator then factors in the individual’s activity level to determine the total number of calories their body burns in a day, also known as their total daily energy expenditure (TDEE).

Once the TDEE is determined, the deficit calculator helps individuals determine the appropriate calorie deficit they need to achieve their weight loss goals. It is generally recommended that individuals aim for a calorie deficit of 500-1000 calories per day to lose 1-2 pounds per week. However, it is important to note that a deficit greater than 1000 calories per day is not recommended as it can lead to muscle loss and other negative health effects.

Using a deficit calculator has several benefits. Firstly, it provides individuals with a clear understanding of the amount of calories they need to consume to achieve their weight loss goals. This information can help individuals make more informed decisions about their diet and exercise habits. Secondly, using a james smith calculator reviews helps individuals avoid the common misconception that weight loss is solely about cutting calories. Instead, it emphasizes the importance of creating a calorie deficit through a combination of diet and exercise. Finally, a James Smith Calculator can help individuals track their progress and make adjustments as necessary to achieve their weight loss goals.

When using a deficit calculator, it is important to keep a few things in mind. Firstly, it is important to be honest when inputting information about your activity level. Overestimating your activity level can result in an inaccurate TDEE, which can negatively impact your weight loss progress. Secondly, it is important to remember that the deficit calculator is simply a tool and should not be relied on solely for weight loss. It is important to combine the use of a deficit calculator with other healthy habits such as regular exercise, a balanced diet, and adequate sleep.

Flexible Dieting and IIFYM

It’s a good idea to expand on these terms commonly mentioned in the fitness industry. You may have heard of flexible dieting from fitness people or you may have heard of the ‘if it fits your macros’ movement (IIFYM). I’ll clarify the differences. I have touched on macronutrients briefly before. But essentially, the idea of tracking ‘macros’ is to set yourself goals to hit each day to get what is optimal* from your diet, which is commonly known as a ‘macro split’. Fun fact: adding up your macros equals your calories. With protein at 4 calories a gram, to consume 20g of protein would equate to 80 calories.


I alluded earlier on to the fact that athletes and fitness people have often been misled about what is a ‘good diet’ and what is a ‘bad diet’ for them. For years, I’ve seen confusion over what is an optimal amount to eat (and even when to eat), and this is the case even with people in very good shape playing at elite levels of sport. I have found over the years that the best athletes tend to do so well through their attitude and determination within their field, but I’ve been very surprised to see what some fantastic athletes actually eat on a daily basis. Some have such a poor understanding of nutrition, it’s actually crazy. By the end of this book, you’ll be better clued up than most Premier League football players.

The origin of IIFYM comes from what I can only assume were conversations between coaches and their clientele. ‘Coach, can I eat pasta?’ And the response: ‘Sure, if it fits your macros.’ ‘Coach can I eat some bread today?’ The response again: ‘Sure, IIFYM.’ A bit like, ‘C’mon, mate. I set your macros – if it fits, go for it.’ Now, this IIFYM mentality did great things and evolved into the term ‘flexible dieting’. I’m sure the Pareto principle of 80/20 was thrown around a lot too in Internet discussions – 80 per cent good food, 20 per cent junk – but, unfortunately, IIFYM over the years has been interpreted as: ‘Eat shit but make it fit your macros and you’ll be fine.’ This isn’t what anyone ever intended with this concept.

Now, of course, you’re always going to find people who abuse any system and don’t do very well – in the same way that I’d very easily abuse the ‘intuitive eating’ lifestyle by interpreting the guidelines so that I can eat whatever I like: ‘Oh, mate, I had three burgers today, but if I drink six scoops of whey protein, it will fit my macros.’

There are many more complex components beyond macronutrients that are essential to looking and feeling good and living a healthy life: food quality, unprocessed ‘single-ingredient’ foods, vegetables, fruit, fibre, variety – these all contribute to our health and make up the essential vitamins that we need. Another component is food volume. I always ask my clients to expand their food choices by selecting lower calorie foods that could increase the amount on their plates. This would typically include, for example, more vegetables, rice, fruits and leaner meats and protein.

However, what I have found is that following macronutrient goals gives people the initial momentum for improvements to their diet. I’ve found that even just setting a protein goal alone has seen a spontaneous improvement in the quality of the diets of my clients over the years. I’d also back the fact that even just being mindful of caloric intake, whether divided into macronutrients or not, would have a massive impact on the amount of food you eat.

When I give a regular person, who could be very new to dieting or even tracking their food, a mid-tier protein target, suddenly some form of planning has to occur, and it’s very rare for someone – even if they are new to eating in either of the aforementioned manners (IIFYM or flexible dieting) – to sit down with their family with just a chicken breast on their plate.

More care goes into the intake of the food, and that is compounded over time. A lot of this game is about being mindful of our food consumption. All too often we eat out of boredom, or because something catches our eye, or a smell gets us interested as we walk past a bakery.

For thousands of years food was scarce, and although the food industry has a target on its back, of course they’d be silly not to make calorie-dense foods, hedonic by nature, very appealing to the eye and the taste buds (after all, they say the first taste of your food is in how it looks). And I don’t think we can criticize or abuse the food industry for doing this.

Everything is about marketing – whether it’s putting sprinkles on a doughnut or making yourself look good to ‘market’ yourself when asking a stranger if they ‘come here often?’ But being conscious of your goals and aware of the calorie content of certain foods, even when something appeals to you, will strengthen the argument in your head to say what’s most difficult in the world of fat loss: ‘No thanks, I’m good.’ If I were to use my James Smith Academy calculator online I could get a macronutrient split back that may look like this:

‘Thank you for using the James Smith Hypothetical calculator, your macronutrient goals are:

190g protein, 44g fat, 200g carbs.’

So to translate the macronutrients into calorie totals:

190g x 4kcals per gram + 44g x 9kcals per gram + 200g x 4kcals per gram = 1,956 calories That’d be my ‘macro’ goal.

Flexible dieting

Flexible dieting and IIFYM can be used interchangeably, but I personally have an alternative take on how to do it. My version of flexible dieting is a slightly different approach to dividing your macronutrients up and how you prioritize what to structure first. What I get my clients to do is assess and then implement everything in order of importance.

Of course, for someone looking to lose fat, the bottom of the pyramid is calories. It shouldn’t matter how much of each macronutrient you’re consuming if you’re not hitting your calorie target. Protein is the second key player here. You’ll find out a lot more about protein in this book, but it plays a big role in muscle growth and fat loss.

You’ll have a very tough time at either end of the spectrum, whether your goal is muscle growth or fat loss, should you not get enough protein. Carbohydrates and dietary fats are both energy sources with their own respective benefits, but when it comes to looking to lose fat, you can select what suits you based on personal preference.

I find IIFYM a very rigid and strict structure compared to my preferential ‘flexible’ approach. Again, this probably depends on the person. If you are someone who loves numbers and works in tax and accounting, you might like the idea of having numbers to aim for each day.

Someone like myself, who’d rather get caught up over two numbers than three, might prefer the more flexible approach.

To give you an idea of what I mean, let’s use the same macro goal as before:

190g protein; 44g fat; 200g carbs Ideal scenario Calories met closely 1,956 = c. 2,000 each day or even c. 14,000 weekly.

Protein met closely 190g = as close to 190g as possible each day.

Carbs and fats = remaining calories after protein to be split according to personal preference, but ideally, do not eat a very low-fat diet (typically, I’d never recommend going lower than 20 per cent of total calories from fat).

Not-so-ideal day

Calories met, slightly overshot = if overshot, implement reduction over following days.

Protein under hit = next day, try to do better, maybe add a protein shake.

Carbs and fats = next day, try to be more calculated with which energy macronutrient you prioritize – for instance, if you have an evening training session and the next day you’re training early, it would make more sense to consume more carbohydrates to help you fuel the following day’s session.

Bad day

Like a majority vote we don’t need every day to be a winner, just the majority. Keep in mind that people who are in good shape for a living rarely get long streaks of success without a bad day; they often just call it a ‘cheat day’ to mask the fact they’ve had a bad day. We can’t expect our diet to be good all the time – it never is. It’s just about getting more good days than bad days.

Train wreck of a day

Make a mental note or an approximation of calories consumed or don’t even track at all if personal circumstances are bad; remember that saying – ‘one hot day doesn’t make a summer’.

Your position can be anywhere within the many shades of success, and everything becomes more of a spectrum of suboptimal to optimal rather than black or white, good or bad, success or failure. So you will sit somewhere on this spectrum with both your diet and your training every day. All we want to do is move towards the optimized end of the spectrum whenever possible.

The truth is, you never really need to be fully optimal. To live that life you’d have no alcohol, go to sleep at 8 p.m. every night and probably never have children. If we all aimed for a perfectly optimal life, it would be pretty boring. The reason I prefer a more flexible approach is so that some days it’s okay to give your diet less attention and focus, and that is fine – it’s a part of being human.

All I want from you is to implement some processes each day, those habits and whatever you do to bring you in line with being as optimal as possible. I don’t expect you to hit your protein every day, but try on as many days as possible. I don’t expect every training session to be spectacular, but keep it as intense as possible. Truth is, things get in the way of an optimal world.

An argument with your partner, feeling under the weather, rain on the way to work when you’re late already. This is all about getting the best possible scenario each day and not beating yourself up if you have a bad one; it’s not wasted, it’s just suboptimal. The main objective is to get more days optimal then suboptimal. It might sound oversimplified, in which case I’m glad, because it’s true, and it’s attainable.

In addition to using a deficit calculator, there are other strategies individuals can use to create a calorie deficit and achieve their weight loss goals. One effective strategy is to increase physical activity. Exercise not only burns calories but also increases muscle mass, which can boost metabolism and help individuals burn more calories at rest. Another effective strategy is to focus on eating nutrient-dense foods such as fruits, vegetables, lean proteins, and whole grains. These foods are low in calories but high in nutrients, which can help individuals feel full and satisfied while consuming fewer calories.

It is also important to avoid crash diets and extreme calorie restriction as these can have negative impacts on health and result in rebound weight gain. Instead, individuals should focus on creating sustainable lifestyle changes that promote long-term weight loss and overall health.

In conclusion, a deficit calculator is a valuable tool for individuals looking to lose weight or maintain a healthy weight.
