Nutritional Value

How many grams of carbohydrates should I consume for a light-intensity workout?

To fuel a light-intensity workout, it is recommended to consume 3 to 5 grams of carbohydrates per kilogram of body weight each day, according to Mayo Clinic. This equates to 200 to 340 grams a day for someone who weighs 150 pounds. Eating a balanced diet with adequate amounts of carbohydrates, proteins, and healthy fats is essential for performance and recovery.

What are the benefits of the ketogenic diet?

The ketogenic diet is an effective way of losing excess body fat without hunger and improving certain health conditions, as demonstrated by many studies. It involves cutting down on carbohydrates and replacing them with high-fat foods.

Studies have also shown that diets high in protein and healthy fats can help promote a healthy metabolism and control hunger.

What are the dangers of consuming too much fat and carbohydrates?

In conclusion, reducing fat and increasing carbohydrates beyond 50% is not an easy task, and most people tend to revert back to the hyper-palatable mix of fat and carbs. According to a study done by Optimising Nutrition in Sep 20, 2022, on, non-fibre carbohydrates beyond 50% can result in less food intake, but this is not easy to achieve. The combination of fat and carbs has been found to be more palatable.

Can eating more fat help with fat loss?

Eating more fat to lose body fat is a myth propagated by the keto diet movement. According to Optimising Nutrition, this notion that you should 'eat fat to satiety' is false, as food quality is also an important factor in determining fat loss. Research has shown that consuming an appropriate amount of protein and carbohydrates can also help promote fat loss.


Are low-carb diets more effective for weight loss than low-fat diets?

Low-carb diets may be more effective in short-term weight loss than low-fat diets, according to a study published by Mayo Clinic in 2022. On, it was also found that to lose 1 to 1.5 pounds per week, an individual needs to consume 500 to 750 fewer calories each day.

The evidence suggests that following a low-carb or "fat-adapted" diet can help the body to burn fat rather than carbs to fuel a workout. As reported by a report published by LiveScience in 2016, this type of diet typically includes high-fat foods, moderate amounts of protein, and very few carbohydrates. The report states that this type of diet can help improve athletic performance and increase energy levels.

What is digestion?

Digestion is the process of mechanically and enzymatically breaking down food into substances for absorption into the bloodstream. The digestion of fats, carbohydrates, and proteins is a necessary step for them to be absorbed into the body. Attributed to StatPearls, a publication of the National Institutes of Health, digestion is an important part of the body's physiology and must take place for proper absorption of nutrients. The food we consume contains micronutrients such as vitamins and minerals that do not require digestion before they can be absorbed.

Chemical Composition

Is a reduced-carb diet more effective than a reduced-fat diet for reducing body fat?

A study conducted by the National Institutes of Health in 2020 concluded that a reduced-carb diet was more effective at reducing body fat than a reduced-fat diet, with participants on the reduced-carb diet losing approximately 53 grams of body fat per day. This is due to a shift in metabolism, which resulted in an increase of fat oxidation and a decrease of carbohydrate oxidation. No changes in insulin production or fat burning were observed when participants consumed a reduced-fat diet.

Can a fat-adapted diet help the body burn fat for fuel?

Fat-adapted diets can help the body burn fat, not carbs, to fuel a workout, according to a study done by Live Science in 2016. This diet consists of low-carb meals, and has been shown to increase fat burning during exercise. Studies have suggested that fat-adapted diets may also lead to improved metabolic flexibility and improved insulin sensitivity.

How can we burn fat and lose weight?

Increasing muscle mass is the best way to burn fat and lose weight, according to a study conducted by BarBend in 2021. This can be done through strength training and avoiding long periods of inactivity. Diets high in protein and with limited processed foods are beneficial for fat loss.

Energy Source

How can the body be adapted to use fat as fuel?

Fat adaptation is a long-term metabolic change that allows the body to use fat instead of carbs as fuel, which is often achieved with the keto diet. According to Healthline in 2020, it is achieved through a long-term metabolic adjustment to ketosis. Research suggests that fat adaptation can increase energy efficiency and performance during exercise.

Do low-carb diets lead to greater weight loss than low-fat diets?

Low-carb diets may lead to greater short-term weight loss than low-fat diets, according to Mayo Clinic on in 2021. This is likely because they reduce the daily calorie intake by reducing carbohydrate intake. Long-term studies have found that the effects of low-carb diets on weight loss tend to be more modest than those of low-fat diets.

Which type of diet is more effective for reducing body fat: low-carb or low-fat?

Reducing body fat is more effectively achieved by cutting calories from dietary fat than from carbohydrates, with participants in one study losing 68% more body fat when cutting calories from fat. An info from a study conducted by the National Institutes of Health in 2020, participants on a reduced-carb diet lost about 53 grams of body fat per day, while those on a reduced-fat diet lost about 89 grams per day. Eating a balanced diet with plenty of fruits and vegetables is also important for optimal health.

Glycemic Index

What is the glycemic index?

The glycemic index (GI) is a measure of how much specific foods increase blood sugar levels, with low, medium, and high glycemic foods ranked on a scale of 0–100 according to Healthline, Jun 2 2020. Foods that have a lower GI are slower to digest and cause a slower, more gradual rise in blood sugar levels.

What foods are part of a low-GI diet?

Eating a low-glycemic index (GI) diet suggests foods that have low GI values, ranging from 1 to 55, to help control blood sugar levels. Attributed to the Mayo Clinic, a low GI diet may be beneficial for people with diabetes or prediabetes in order to help regulate blood sugar levels. Research suggests that it may also benefit people trying to lose weight or reduce their risk of heart disease.

What is the benefit of eating foods with a low glycemic index?

Eating foods with a low glycemic index can create more gentle blood sugar and insulin levels, as measured by the glycemic index rating system. As mentioned in Harvard Health, this can help avoid the hunger that often follows a high glycemic index food-related spike in blood sugar. Eating a balanced diet with healthy fats, proteins, and carbohydrates is key for maintaining healthy glycemic levels.

Glycemic Load

Does insulin affect fat burning?

Insulin impacts the rate at which your body burns fat, regardless of whether or not you are consuming carbohydrates. Mentioned in Precision Nutrition, high glycemic load carbohydrates with low overall nutritional value can lead to weight gain. Research has shown that reducing added sugar intake can aid in successful weight loss.

What is the Glycemic Load?

The Glycemic Load (GL) is an effective tool for measuring the impact of a food on blood sugar levels, with a low GL indicating a smaller effect. Sourced from Everyday Health, the GL is calculated by multiplying the Glycemic Index (GI) of a food by the amount of carbohydrate it contains, and then dividing that number by 100. For example, a medium-sized apple has a low GL of 6. Knowing the GL of foods can help people make informed decisions about their diet.

Does a high glycemic load affect insulin secretion?

A high glycemic load total for any given day can lead to a greater secretion of insulin in response to carbohydrates in the diet, according to This is because insulin is released in response to carbohydrates consumed. Research has shown that a diet high in carbohydrates can be beneficial for both fat loss and muscle building.


What is the thermic effect of protein?

Metabolism is the process of breaking down food and storing it for energy, and protein has a higher thermic effect compared to fats and carbohydrates. This was first established by Harvard Health in 2021, and it is important to note that the body takes longer to process protein than other food sources.

Do humans possess fat cells that burn fat?

Harvard Medical School and other institutions discovered in 2009 that humans have both white fat cells and also brown fat cells, which burn fat rather than store it. This major fat-burning discovery has enabled individuals to better control their weight and lose weight more effectively.

How can strength training help improve health and fitness?

Strength training is an effective way to reduce body fat, as demonstrated by Healthline in 2021. This method of exercise helps to burn fat and build muscle, improving overall health and fitness.
