James Smith Daily Calorie Intake Calculator


James Smith Daily Calorie Intake Calculator is an online tool that helps you determine how many calories you need to consume each day to achieve your goals. These calculators take into account your age, sex, weight, height, activity level, and weight goals to estimate your daily calorie needs.

Maintaining a healthy lifestyle requires a balanced diet and regular exercise, but how many calories should you consume each day to achieve your goals? This is where a daily calorie intake calculator comes in handy. In this article, we will explore what a daily calorie intake calculator is, why it’s important, and how to use it.

Why is it Important to Know Your Daily Calorie Intake?

Knowing your daily calorie intake is crucial for maintaining a healthy lifestyle. Consuming too many calories can lead to weight gain and obesity, while consuming too few calories can lead to malnutrition and other health problems. By knowing your daily calorie intake, you can make informed decisions about the foods you eat and ensure that you’re meeting your nutritional needs.

How to Use a Daily Calorie Intake Calculator?

Using a daily calorie intake calculator is a straightforward process. Here are the steps to follow:

Step 1: Input Your Personal Information

The first step is to input your personal information, including your age, sex, weight, height, and activity level. Some james smith calculator UK may also ask for your goal weight and how much weight you want to lose or gain each week.

Step 2: Determine Your Basal Metabolic Rate (BMR)

The next step is to determine your basal metabolic rate (BMR). This is the number of calories your body needs to maintain basic functions, such as breathing and circulation, while at rest. The james smith academy calculator will use your personal information to estimate your BMR.

Step 3: Calculate Your Total Daily Energy Expenditure (TDEE)

The next step is to calculate your total daily energy expenditure (TDEE). This is the total number of calories your body needs each day, taking into account your activity level. The james smith diet calculator will multiply your BMR by a factor based on your activity level.

Step 4: Set Your Calorie Goals

Once you know your TDEE, you can set your calorie goals based on your weight goals. If you want to lose weight, you’ll need to create a calorie deficit by consuming fewer calories than your TDEE. If you want to gain weight, you’ll need to consume more calories than your TDEE.

Step 5: Track Your Progress

Finally, it’s important to track your progress and adjust your calorie intake accordingly. If you’re not seeing the results you want, you may need to adjust your calorie intake or increase your exercise level.

Branched Chain Amino Acids – BCAA

I must admit, as a PT I was guilty of supplementing these for a long time. In my head, I always have the argument that ‘if a placebo works, it works’. However, these supplements are not cheap, and as if protein in itself didn’t cost the average fitness person an arm and a leg, I don’t think anyone deserves the ‘stupid tax’ of paying for BCAAs on top. Amino acids form protein, the ‘building blocks’, so to speak.

So I thought that having these in circulation would only benefit me and ‘protect’ my muscle when unfed, dieting or training. Turns out there’s no need for these supplements at all, according to the science, keeping in mind we have two hours’ training’s worth of muscle glycogen most of the time, plus, if we are hitting our protein targets (1.5– 2.5g per kg) there should be sufficient amino acids in circulation. There’s emerging data surrounding BCAAs helping with DOMS (muscle soreness), but I don’t think they warrant necessity among anyone I have trained in the past or anyone I am likely to train in the future.

Protein is required for growth and repair of the body and tissues. The amount is usually chosen relative to the size of the person – that’s why I have put ‘per kilogram’ throughout this book. If you’re carrying a fair bit of timber (fat), it’s a good idea to choose an amount of protein that is relatively close to your lean mass (without fat). So if you’re 100kg and have a feeling you’re carrying around 20kg of fat – your lean body mass (the amount of mass without fat on it) would be 80kg.

Now, the sliding scale (1.5–2.5g) has more to do with your goal and environment of training. If you’re someone getting into fitness and it’s your first time calculating your protein goal, I recommend the lower end of 1.5g per kg. To most of the fitness industry, this is considered fairly low; however, for someone new to this way of eating, I think it’s the perfect amount to maximize the benefits of higher protein without flipping someone’s diet and way of eating upside down.

If you’re dieting in a big deficit or looking to maximize muscle growth, then it’s worth aiming for the higher ranges – up to 2.5g per kg. I weigh about 91kg without much fat, so that’s 227.5g of protein a day. The important thing here is that weight is not the weight of the protein source itself. For instance, a chicken breast may weigh 100g and only have 10–20g of protein in it.

To give you a visual idea of 227.5g of protein – it’s give or take ten scoops of whey protein, which is circa 25g a scoop. That’s not to say you should drink ten shakes a day; it’s just to give you an idea of how much that is for me. Linda from Norwich is looking to lose 10kg. She’s currently weighing 79kg. Let’s decide she’s 69kg lean and she’s relatively new to dieting.

So we take 69kg x 1.5g = 103.5g protein per day. That could be a scoop of whey with a yoghurt for breakfast (40g) followed by a salmon salad at lunch (25g), some chocolate rice cakes mid-afternoon before exercising (0g), a shake post-workout (25g), then for dinner she’d only require 20g, which could easily fit into any traditional dish she’s cooking with her family or friends.†† What does the scientific literature say? ‘There is a paucity of evidence supporting a beneficial effect for BCAA supplementation in promoting increases in muscle protein synthesis or lean mass.’ I had to google that one.

Some of the evidence out there when examined is incorrect. Often companies will ‘sponsor’ a study to go ahead and the findings usually conveniently come back with the best interest of the sponsor. To conclude. There’s no real reason or benefit for anyone to supplement BCAAs in a calorie deficit or even in a state of looking to build muscle. Focus should be on total protein intake from food. It’s a shame because most mainstream training plans that we see recommend BCAA supplementation with a ‘discount code’. Unfortunately, these are, in fact, commission codes for the person who has written the plan.


A daily calorie intake calculator is an essential tool for anyone looking to maintain a healthy lifestyle. By knowing your daily calorie needs, you can make informed decisions about the foods you eat and ensure that you’re meeting your nutritional needs. Whether you want to lose weight, gain weight, or maintain your current weight, a James Smith Calculator can help you achieve your goals. So, why not give it a try and see what your daily calorie intake should be?
