When it comes to nutrition, the global weight management market is expected to reach USD 442.3 billion by 2025. It’s no surprise that most people are completely confused about what the best nutrition strategy or diet is that will help us achieve a weight loss goal.
This article is designed to give you some fundamental starting points when it comes to nutrition without the marketing BS.
Key Takeaways
- Proper nutrition is essential for maintaining good health and preventing chronic diseases.
- A healthy diet should include a variety of nutrient-dense foods, such as fruits, vegetables, whole grains, lean proteins, and healthy fats.
- The six essential nutrients are carbohydrates, fats, proteins, vitamins, minerals, and water.
Fundamentals of Nutrition
Macronutrients and Micronutrients
Nutrients can be classified into two types: macronutrients and micronutrients. Macronutrients are nutrients required in large quantities by the body, such as protein, carbohydrates, and fats. Micronutrients, on the other hand, are required in small quantities, and include vitamins and minerals. Macronutrients provide energy to the body, while micronutrients are essential for various bodily functions such as metabolism, growth and development, and immune function.
Role of Vitamins and Minerals
Vitamins and minerals are essential micronutrients that play a crucial role in maintaining good health. Vitamins are organic compounds that are required in small amounts and are essential for various metabolic processes in the body. Minerals, on the other hand, are inorganic compounds that are required in small amounts and play a vital role in various bodily functions such as bone health, nerve function, and immune function.
Importance of Water
Water is an essential nutrient that is required for various bodily functions such as digestion, absorption, and transportation of nutrients. It also helps regulate body temperature and plays a crucial role in maintaining good health. It is recommended that adults consume at least 8 cups of water per day.
The Importance Of Fibre
Fibre is a type of carbohydrate that is not digested by the body. It plays a crucial role in maintaining good health by promoting regular bowel movements, lowering cholesterol levels, and reducing the risk of heart disease and certain types of cancer.
Recommended Daily Protein Intake
Protein is an essential macronutrient that plays a crucial role in building and repairing tissues in the body. It is recommended that adults consume at least 0.8 grams of protein per kilogram of body weight per day.
To support weight loss, studies are revealing that increasing your protein up to 1.6g per kilogram of body weight per day can assist in moving the unwanted weight.
Balanced Diet
A balanced diet is essential for good nutrition. It should include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats. It is also important to limit the intake of processed foods, saturated fats, and added sugars.
Dietary Guidelines
Dietary Guidelines can be helpful and provide recommendations for healthy eating to help reduce the risk of chronic diseases such as heart disease, diabetes, and obesity. Commonly accepted guidelines recommend consuming a variety of nutrient-dense foods and beverages, limiting the intake of saturated and trans fats, added sugars, and sodium, and staying within calorie limits.

The Impact Of Destructive Patterns
Nutrition plays a crucial role in the overall health and well-being of an individual. The food that one eats provides the necessary nutrients for growth, longevity, and energy. However, certain destructive patterns of eating can harm one’s health. In this section, we will discuss the impact of destructive patterns such as binge eating, undereating, and yo-yo dieting.
Binge Eating
Binge eating is a pattern of eating where an individual consumes a large amount of food in a short period of time. This can lead to obesity, which in turn can lead to a host of health problems such as heart disease, diabetes, and cancer. It is essential to understand the root cause of binge eating, which can be due to emotional issues such as stress, anxiety, and depression. Seeking help from a mental health professional can be beneficial in addressing the underlying issues that lead to binge eating.
Undereating
Undereating is a pattern of eating where an individual consumes fewer calories than their body requires. This can lead to undernutrition, which can have a negative impact on health and longevity. Undernutrition can also lead to a weakened immune system, making an individual more susceptible to infections and diseases. It is essential to consume a balanced diet that provides the necessary nutrients for the body to function correctly.
Yo-Yo Dieting
Yo-yo dieting is a pattern of weight loss and gain that can have a negative impact on an individual’s health. This pattern of weight loss and gain can lead to obesity or other eating disorders, which in turn can lead to a host of health problems such as heart disease, diabetes, and cancer. Yo-yo dieting can also lead to a weakened immune system, making an individual more susceptible to infections and diseases. It is essential to adopt a healthy lifestyle that includes a balanced diet and regular exercise to maintain a healthy weight.
Simple Principles For Weight Loss
Losing weight is a common goal for many people, and while there are many different approaches to weight loss, there are some simple principles that can help make the process easier and more effective.
Total Energy Expenditure
One of the most important principles of weight loss is understanding Total Energy Expenditure (TEE). TEE is the total number of calories a person burns each day, including calories burned through physical activity and basic bodily functions. A person’s TEE can be calculated using their age, weight, height, and activity level.
From over a decade of experience, people will usually grossly overestimate the amount they move in a given day.
Maintaining A Calorie Deficit
To lose weight, a person must maintain a calorie deficit, which means they must burn more calories than they consume. This can be achieved through a combination of reducing daily intake and increasing physical activity.
Track It
What gets measured gets mastered. Instead of jumping straight onto a restrictive yoyo diet, take some time to track the relevant data to find your best course of action. As before, there’s a good chance that this has been a long-term journey and giving yourself 7-14 days to track and measure will have no negative impact on your progress.
Look for risk periods in your week and triggers that you can target. Find the biggest opportunity and focus on that. For example, if you’re someone who is well-controlled from Monday to Wednesday after having a restful weekend there is no point putting controls around these days. Focus on optimising, automating or eliminating the risks and triggers from Thursday to Friday in order to have the best return on investment.
Here are some low-tech/low-time methods to Track It:
- Journalling – Using a written journal or app is a great method for self-reflection and pattern identification
- 0-5 Scales – Use simple point scales to measure the impact of activities and inputs.
- Caloric Trackers – Use apps like MyFitnessPal to track what you eat. The important thing here is to do nothing more. Tracking gets a bad rap from time to time but using it as a self-awareness exercise is not harmful. You can stop when you have enough information
- Low Tech Tests & Measurements – Use tests like blood panels and the waist-to-hip ratio. By using these free, low-investment methods you can get an accurate measure of what you need to work on and track your progress over time.
Bracket
Once you have the data, define your goal. Be specific and aim for long-term targets to reduce or avoid unrealistic expectations. For clarification, sustained and successful weight loss is defined as being maintained for 2 years post-intervention.
Try and aim for only a small deficit like 100-200 calories to begin with to avoid the crash from restricting your intake too much.
For those suffering overwhelm due to the realisation of how bad things have gotten, aim for weight maintenance first. By focusing on the regulation of our current state rather than immediate restriction gives us a chance to ease into the journey and increase our self-awareness around the problem.
Forcing Functions
Creating forcing functions can also help maintain a calorie deficit. For example, removing processed foods from the home or setting reminders to take a walk after meals can help encourage healthy habits.
Eating off smaller plates and bowls also gives you an easy indication if you’re eating too much.
Automating, Optimising & Eliminating
Automating healthy habits, optimising meal planning, and eliminating unhealthy foods can also be effective strategies for weight loss. This includes incorporating more whole foods into the diet and reducing or eliminating processed foods.
Overall, while weight loss can be challenging, understanding TEE, maintaining a calorie deficit, tracking progress, and incorporating healthy habits can make the process easier and more effective.

The Impact Of Sleep, Stress & Stimulants
Nutrition is an essential component of a healthy lifestyle, but it is not the only factor that affects one’s well-being. Sleep, stress, and stimulants also play a crucial role in maintaining a healthy body and mind.
Sleep
Sleep is essential for the body to repair and regenerate itself. Lack of sleep can lead to a range of health problems, including obesity, diabetes, and cardiovascular disease. Additionally, sleep deprivation can affect one’s mental health, causing anxiety, depression, and irritability.
Several factors can negatively affect sleep quality, including the use of stimulants, stress, anxiety, and the use of electronic devices before sleep. On the other hand, a growing body of evidence suggests that nutrition, physical activity, and sleep hygiene can significantly affect the quality of sleep.
Stress
Stress is a natural response to challenging situations, but chronic stress can lead to a range of health problems, including high blood pressure, heart disease, and depression. Stress can also affect one’s eating habits, leading to overeating or undereating.
To manage stress, it is essential to identify the source of stress and develop coping mechanisms. Additionally, incorporating stress-reducing activities, such as exercise, meditation, and yoga, can help reduce stress levels.
Stimulants
Stimulants, such as caffeine and nicotine, can affect one’s sleep quality and stress levels. Caffeine can disrupt sleep patterns and increase anxiety, while nicotine can increase heart rate and blood pressure, leading to stress.
It is essential to limit the intake of stimulants, particularly before sleep, to improve sleep quality and reduce stress levels. If you’re someone with a substance abuse problem, please seek professional help before using anything in this guide as a starting point.

Diet and Health Conditions
Maintaining a healthy diet is essential in preventing and managing various health conditions. In this section, we will discuss some of the most common health conditions and how they are affected by diet.
Our Genetic Set Point For Weight
While genetics play a role in determining an individual’s weight, it is important to note that diet and physical activity also play a significant role. A healthy diet can help individuals maintain a healthy weight and reduce the risk of obesity-related health conditions.
It has long been discussed that humans may have a ‘set point’ when it comes to our weight. Although it should not stop someone from making the necessary lifestyle and habit changes, here is some further reading on the product of genetic effects (DNA), epigenetic effects (heritable traits that do not involve changes in DNA), and the environment.
Obesity and Weight Management
Obesity is a major health concern that can lead to various health conditions such as type 2 diabetes, cardiovascular disease, and certain types of cancer. A healthy diet that is low in calories and high in nutrients can help individuals manage their weight and reduce the risk of obesity-related health conditions. Additionally, regular physical activity can help individuals maintain a healthy weight and improve overall health.
Diabetes and Glycemic Control
A healthy diet that is low in sugar and refined carbohydrates can help individuals manage their blood sugar levels and reduce the risk of type 2 diabetes. It is important to monitor carbohydrate intake and choose complex carbohydrates such as whole grains, fruits, and vegetables. Additionally, regular physical activity can help improve glycemic control and reduce the risk of type 2 diabetes.
Heart Disease and Cholesterol
Heart disease is one of the leading causes of death worldwide. A diet that is high in saturated and trans fats, cholesterol, and sodium can increase the risk of heart disease. On the other hand, a diet that is rich in fruits, vegetables, whole grains, lean protein, and healthy fats can help reduce the risk of heart disease. In particular, foods that are high in fibre, omega-3 fatty acids, and antioxidants are beneficial for heart health.
Role of Nutrition in Disease Prevention
Nutrition plays a crucial role in disease prevention. A balanced diet that includes a variety of nutrient-dense foods can help reduce the risk of chronic diseases, boost the immune system, and improve mental health.
Reducing Chronic Health Conditions
Chronic health conditions, such as diabetes, obesity, and cancer, are often linked to poor nutrition. A diet that is high in processed foods, sugar, and unhealthy fats can increase the risk of chronic health conditions. On the other hand, a diet that is rich in whole, nutrient-dense foods can help reduce the risk of chronic health conditions. In particular, a diet that is high in fibre, vitamins, and minerals can be beneficial for overall health.
Boosting the Immune System
The immune system plays a critical role in protecting the body from infection and disease. A diet that is rich in vitamins, minerals, and antioxidants can help boost the immune system. In particular, foods that are high in vitamin C, vitamin D, and zinc are beneficial for immune function.
Reducing Inflammation
Inflammation is a natural response of the immune system to injury or infection. However, chronic inflammation can contribute to the development of chronic diseases, such as heart disease, diabetes, and cancer. A diet that is high in processed foods, sugar, and unhealthy fats can increase inflammation in the body. On the other hand, a diet that is rich in whole, nutrient-dense foods can help reduce inflammation. In particular, foods that are high in omega-3 fatty acids, antioxidants, and fibre are beneficial for reducing inflammation.
Nutrition and Mental Health
Nutrition also plays a critical role in mental health. A diet that is high in processed foods, sugar, and unhealthy fats can increase the risk of depression and anxiety. On the other hand, a diet that is rich in whole, nutrient-dense foods can help improve mental health. In particular, foods that are high in omega-3 fatty acids, B vitamins, and magnesium are beneficial for mental health.
