Hello Ziddis! If you are in the zone to lose weight, you must have gotten a lot of advice to try going into a calorie deficit. But what does this mean? Can going ‘calorie deficit’ really help? Understand that fat loss doesn’t require extreme diets or starvation. It comes down to one fundamental concept: energy balance. A calorie deficit is not about depriving your body of nutrients; it’s about understanding how much your body truly needs.

What Does Calorie Deficit Mean?

A calorie deficit occurs when the number of calories consumed is less than the number of calories the body burns in a day. The body requires a certain number of calories to perform even mundane involuntary functions, such as:

• Basic functions (breathing, digestion, heartbeat)
• Physical activities (such as walking)
• Cellular processes (repair, hormones)
• The total number of calories required is called the Total Daily Energy Expenditure (TDEE).
• Calories consumed = Calories burned. This results in no change in weight.
• When Calories consumed > Calories burned, you gain weight.
• When Calories consumed < Calories burned, you lose weight.

In a calorie deficit, the body does not receive the required calories from the food consumed. Thus, it begins to utilise the body fat for energy.

Calorie Deficit Diet

A calorie-deficient diet is a plan that allows an individual to maintain a calorie intake below their daily requirement. Here’s an important thing to note: Not all calorie deficits are good. A good calorie deficit should be:

• Not extreme
• Provide enough amounts of proteins, fats, and carbohydrates
• Provide enough calories to meet energy demands

Whereas an extreme calorie deficit will not be an effective diet plan because:

• Slows down metabolism
• Results in muscle loss
• Results in fatigue and binge eating

The metabolism slows down to help an individual survive.

Calorie Deficit Calculator

A calorie deficit calculator can estimate the number of calories you need to consume each day to lose weight.

A calorie deficit calculator can consider the following factors:

• Age
• Gender
• Weight
• Height
• Activity level

A simple way to calculate a calorie-deficient diet plan:

• Estimate the maintenance calories an individual requires. This can be done by calculating their daily energy expenditure.
• Subtract 300 to 500 calories from their daily requirement to reduce fat.

For example:

• Maintenance calories = 2000 kcal
• Fat loss calories = 1500 to 1700 kcal

Healthy deficit ranges:

• Mild: 200–300 kcal (slow, sustainable)
• Moderate: 300–500 kcal (ideal for most people)
• Aggressive: 500–800 kcal (short-term only, with caution)

For your goal (losing ~1.5–2 kg in a month), a moderate deficit + activity is perfect.

Calorie Deficit Diet for Weight Loss

To lose fat effectively, the diet should be based on “quality + quantity,” rather than “quantity alone.”

1. Protein is Good

• Preserves muscles
• Fills you up
• Increases metabolism slightly
• Dal
• Tofu
• Chicken
• Eggs
• Plant-based protein (great because you are avoiding cow milk)
• Peanut butter
• Whey protein

2. Fibres should be included

• Fruits
• Vegetables
• Whole grains

3. Don’t be scared of fat as long as it’s from

• Nuts
• Seeds
• Olive oil

4. Avoid “liquid calories”

• Sugary drinks
• Too many coffee add-ons

Takeaway

A calorie deficit is the only scientifically proven method of losing fat, “but the manner in which you achieve a deficit is just as important as the deficit itself.” The aim isn’t simply to lose weight; it’s to develop a body and lifestyle that you can comfortably maintain.

Hello Ziddis! You may remember something called ATP from biology class. However, once you begin to exercise, you need to understand the importance of ATP. Any movement you make, such as when you lift a weight, sprint down the track, or even make a muscle, all depends on one molecule called ATP. It is often called the energy currency of the body, meaning it provides immediate energy to allow muscles to function. Understanding the importance of ATP helps you recognise the importance of strength, power, and endurance, driven by the efficiency of energy production in the body.

Adenosine Triphosphate

Adenosine Triphosphate (ATP) is a chemical in every human cell. It is used to store and carry energy needed for essential bodily functions, including muscle contraction, nerve impulses, and protein synthesis.  

Adenosine Triphosphate is composed of three parts:  

• Adenine (a base with nitrogen)  
• Ribose (sugar)  
• Three phosphate groups  

The energy is stored in the bonds that are formed between the three phosphate groups. When the body needs energy quickly, such as during a heavy lift, the bonds are broken. Muscles contain a small amount of ATP, typically enough for only a few seconds of maximal work. This means the body must continually produce ATP for the muscles to continue working.

Hydrolysis of ATP

The process by which energy is released from the molecule is called ATP Hydrolysis. ATP Hydrolysis occurs when the phosphate bond of ATP is cleaved by the addition of water. During exercise, millions of ATP molecules are hydrolysed every second. During strenuous activities such as sprinting and jumping, the energy stored in ATP is depleted within 2 to 3 seconds. If the energy is not replenished, the muscles become weak.

Cellular Energy

To sustain muscle function, the body has developed various energy-producing mechanisms that generate ATP. These mechanisms operate simultaneously, with some performing best at different intensities.

1. The ATP-Creatine Phosphate System

This is the fastest energy-producing system, essential for 10-second energy-intensive activities. The energy is stored as creatine phosphate (phosphocreatine). Phosphocreatine is the quick energy reserve that the muscles utilise when the energy stored in the form of ATP is depleted. The energy is utilised for:

• Heavy weightlifting
• Short sprints
• Jumping
• Explosive athletic movements

Because creatine phosphate stores are limited, they are depleted rapidly during intense exercise.

2. Anaerobic Glycolysis

For activities lasting 10 seconds to 2 minutes, the body begins glucose breakdown without oxygen, producing ATP.

3. Aerobic Energy System

For longer activities, the body produces energy by breaking down carbohydrates and fats with oxygen, producing ATP.

All these energy-producing systems ensure the body maintains a constant supply of ATP, which the muscles require.

Takeaway

ATP is the immediate energy source behind every muscle contraction. During intense exercise, ATP depletes quickly, forcing the body to rely on energy systems that regenerate it. The ATP–creatine phosphate system is especially important for strength and power activities because it rapidly restores ATP during brief bursts of effort. This is why the availability of cellular energy directly affects performance in explosive movements and heavy lifting. Strength and power depend on how quickly your body can regenerate ATP. You are getting smarter by the day and taking care of your health and fitness, so here’s a little tip for you: If you have started regular strength training, then protein powder to make up for the gaps in your protein intake and BCAA supplements to support your muscle building are game changers.

Protein powders are normally represented with a single value: grams of protein per serving. However, this value does not always represent the whole picture. Most traditional methods of testing a protein powder only test for nitrogen, rather than the amount of actual protein your body can use to build muscle.

If you understand how this works, you can avoid many protein powders that promise a high protein content but deliver much less in practice.

Protein Testing

Most protein powders are tested using the Kjeldahl or Dumas method. These methods measure the total nitrogen content of a sample of a given substance.

Why Nitrogen?

Amino acids, the building blocks of proteins, contain a fixed amount of nitrogen in each. Scientists have assumed that if they can measure the nitrogen content of a substance and multiply it by a standard factor, they can estimate the total protein content.

The formula looks something like this:

Step	What Happens
1	The test measures total nitrogen in the sample
2	The nitrogen amount is multiplied by a factor (usually 6.25)
3	The result is labelled as grams of protein

This method works fairly well if the nitrogen source is only intact proteins. But it leaves a hole.

The test cannot distinguish true protein from other nitrogen-containing substances.

Nitrogen in Protein

Protein consists of a chain of amino acids. Each amino acid contains nitrogen. Your body breaks down protein into amino acids and uses them to repair tissue, build enzymes, and support muscle growth as it digests the protein.

Nitrogen is not protein. Manufacturers will use cheaper nitrogen-rich substances that are considered protein during testing but will not provide the same nutritional benefits.

Examples of these include:

Substance	Why It Is Added
Free amino acids like glycine or taurine	Very cheap and high in nitrogen
Creatine	Contains nitrogen and inflates test results
Other nitrogen compounds	Raise measured protein numbers

The problem is that the test does not directly measure protein. It measures nitrogen. These ingredients may cause the protein levels to appear higher than they are. However, they are not actually helping the muscle-building process. This practice is called amino spiking.

Elemental Nitrogen

To better understand the problem of protein spiking, it might be helpful to consider elemental nitrogen.

The term elemental nitrogen refers to the raw nitrogen atoms in a substance. A testing facility can’t know whether the nitrogen they are testing came from:

• complete proteins
• amino acids
• other sources of nitrogen

All of these contribute to the same nitrogen levels. For example:

Ingredient	Nitrogen Detected	True Muscle-Building Protein
Whey isolate	High	High
Glycine	High	Very low value for muscle protein synthesis
Creatine	Contains nitrogen	Not protein

This means the protein powder could be labelled “25 grams of protein” while providing far less complete and usable protein.

Reactive Protein

The term reactive protein refers to a protein that is actually useful to the body. To put it simply, it is the protein that drives muscle protein synthesis.

The quality of protein that the body actually needs is based on the following:

• Complete essential amino acids
• Adequate leucine content
• Digestion and absorption

Essential Amino Acids are the nine that the body cannot make on its own. The diet or a supplement must supply them. A protein supplement that uses non-essential amino acids to boost nitrogen levels may report higher protein levels but offer less effective muscle-building properties.

How to Identify Genuine Protein Quality

However, as a consumer, you can take steps to ensure your safety by looking for a few signs of transparency.

1. Amino Acid Profile Given: The brand is confident in their protein powder if they are providing the entire amino acid profile.

2. Third Party Testing: Third-party testing is a good indicator that a protein powder is genuine.

3. Clear Labelling: Avoid protein powders with proprietary blends and ambiguous ingredient lists.

4. Real Protein Sources: Good protein powder sources include:

• whey isolate protein
• whey concentrate protein
• casein protein
• egg protein

All of these sources contain the entire amino acid profile.

Takeaway

The problem with protein powder is that testing relies solely on nitrogen content. However, there are many nitrogen sources, and some are very inexpensive. The only way to obtain the protein your body needs is to focus on protein content rather than nitrogen content. When researching protein powders, consider complementary foods and protein sources to enhance fitness, such as Fit Foods and oats protein.

Muscle fibres don’t come in a single type. Instead, they come with a mix of slow-twitch and fast-twitch fibres. Both types of fibres are useful for different types of activities. Some help you to last for a long time, while the other type helps you to generate sudden forces. Learning about the types of muscle fibres can help you become a good athlete or a fitness enthusiast. Once you learn about the type of fibres you are working with, you can easily create a routine that meets your training requirements. What is Twitch in Muscle? A twitch is a sudden contraction followed by a sudden release of the muscle fibres due to a nerve signal. Every movement you make, whether you walk or lift weights, occurs due to thousands of twitches.

Muscle Fibres Come in Two Types. 

Feature	Slow-Twitch Fibres (Type I)	Fast-Twitch Fibres (Type II)
Function	These fibres are designed for endurance and sustained activity.	These fibres are built for power and explosive movements.
Contraction speed	Contract slowly	Contract quickly
Fatigue resistance	Highly resistant to fatigue	Fatigue more quickly
Energy use	Use oxygen efficiently for long-duration activity	Use energy rapidly for short bursts of effort
Force production	Produce a lower force but can sustain it longer	Produce higher force and power
Common activities	Long-distance running, cycling, swimming, and steady moderate-intensity workouts	Sprinting, heavy weightlifting, jumping, and high-intensity interval training
Structural traits	Contain more mitochondria and capillaries, which help deliver oxygen and support long-term energy production	Generate greater power, but cannot sustain activity for long periods

Training for slow-twitch muscles typically emphasises endurance. Examples of training methods:

• Long cardio training
• Increased repetitions for strength training
• Reduced resting periods between sets for strength training
• Moderate-intensity endurance training
• Strength-training repetitions for this type of training may be between 12 and 20 per set, using lighter weights.

This type of training helps to develop the following: • Muscular endurance • Oxygen usage • Fatigue resistance. This type of training is usually a priority for endurance sport athletes.

Training for Fast-Twitch Fibres

Fast-twitch muscles usually respond to high-intensity training. Examples of training methods for this type of training:

• Heavy strength training
• Sprint intervals
• Plyometric training
• Olympic lifting training
• Strength training repetitions for this type of training usually range from 1 to 6 per set with heavy weights.

This type of training helps to develop the following: • Strength • Power output • Explosive speed. Athletes who take part in sprinting events, powerlifting, football, etc., usually focus on the development of fast-twitch muscles.

Muscle Twitching Causes

Muscle twitches may also occur in small amounts, even in the absence of exercise. Common reasons for muscle twitches are:

• Muscle fatigue after a strenuous workout
• Stress and anxiety
• Dehydration
• Electrolyte imbalance (low levels of magnesium and potassium)
• Consuming too much caffeine
• Sleep deprivation

Muscle twitches tend to resolve on their own as your body recovers from these factors.

Muscle Fasciculation Causes

A fasciculation in a muscle is a small visible muscle movement under the skin, caused by spontaneous muscle fibre contraction. Reasons why fasciculations happen include:

• Post-exercise muscle fatigue
• Irritation of nerves
• Electrolyte imbalance
• High stress levels
• Overtraining

Most fasciculations are harmless; however, in some instances where muscle twitches are increasing in severity, it is a good idea to seek medical help.

Takeaway

Slow-twitch and fast-twitch muscle fibres have different functions that contribute to physical performance. Slow-twitch fibres contribute to endurance activities, whereas fast-twitch fibres contribute to explosive power. Most training regimens will include both fibre types to a certain degree. However, training intensity, load, and style can be altered to emphasise one over the other. Knowledge of the differences between the two will allow athletes to train more effectively to meet their performance goals.
