Low Glycemic Diet Plan For Weight Loss


Low glycemic diet plan for weight loss – Glycemic index is a term that refers to how quickly carbohydrates are broken down into your bloodstream. The lower the glycemic index of a carbohydrate, the longer it takes to digest and contribute to your blood sugar levels. Therefore, foods with a low glycemic index are recommended for people with diabetes and for weight loss.

The low glycemic diet plan is one of the best methods for weight loss. But it goes beyond weight loss. It manages insulin levels in your body and can help prevent type 2 diabetes . This diet plan also lowers triglycerides, which is a type of fat in your blood

Low Glycemic Diet Plan For Weight Loss

An eating strategy based on how foods affect your blood sugar level is known as a glycemic index diet.

The glycemic index is a system for ranking foods high in carbohydrates in terms of how much they raise blood sugar levels. The glycemic index is a tool that can be used in conjunction with other diet plans, such as calorie or carb counting, to help people make better eating decisions.

The phrase “glycemic index diet” typically describes a particular eating regimen that makes use of the index as the main or sole resource for meal planning. Contrary to some other diets, a glycemic index diet does not always outline serving sizes or the ideal calorie, carbohydrate, or fat intake for weight reduction or maintenance.

The Zone Diet, Sugar Busters, and the Slow-Carb Diet are just a few of the well-known commercial diets, diet manuals, and diet websites that are based on the glycemic index.


A glycemic index (GI) diet aims to consume carbohydrate-rich foods that are less likely to result in significant spikes in blood sugar levels. The diet may help people lose weight and fend off chronic diseases like diabetes and heart disease that are linked to obesity.

Why you might follow the GI diet

You might choose to follow the GI diet because you:

  • Want to lose weight or maintain a healthy weight
  • Need help planning and eating healthier meals
  • Need help maintaining blood sugar levels as part of a diabetes treatment plan

According to studies, a GI diet can assist in achieving these objectives. However, a balanced diet, maintaining a healthy weight, and getting adequate exercise may enable you to obtain the same health advantages.

Before beginning any weight-loss program, especially if you have a medical condition like diabetes, consult your doctor or other healthcare professional.

The glycemic index

The GI principle was initially created as a method for assisting diabetics in making informed meal decisions. Sydney University Glycemic Index Research Services, located in Sydney, Australia, manages a global GI database. Results of studies carried out there and at other research institutes worldwide are included in the database.

Understanding glycemic index diets requires a fundamental understanding of carbs, blood sugar, and GI values.


In food, carbohydrates, sometimes known as carbs, are a type of nutrient. Sugars, starches, and fiber are the three fundamental forms. Your body converts the sugars and starches in foods and beverages that include carbohydrates into glucose, the primary fuel for your body’s cells. Undigested fiber flows through your body.

Your pancreas produces two major hormones that control blood sugar levels. Insulin is a hormone that transports glucose from the blood into your cells. When your blood sugar (blood glucose) level is low, the hormone glucagon aids in the release of glucose that is held in your liver. This procedure maintains a healthy balance of blood sugar and keeps your body nourished.

The qualities of various carbohydrate foods have an impact on how rapidly glucose enters your system and how quickly they are digested by your body.

Understanding GI values

There are various research methods for assigning a GI value to food. In general, the number is based on how much a food item raises blood glucose levels compared with how much pure glucose raises blood glucose. GI values are generally divided into three categories:

  • Low GI: 1 to 55
  • Medium GI: 56 to 69
  • High GI: 70 and higher

Comparing these values, therefore, can help guide healthier food choices. For example, an English muffin made with white wheat flour has a GI value of 77. A whole-wheat English muffin has a GI value of 45.

Limitations of GI values

One drawback of GI ratings is that they don’t accurately represent how much of a particular food you would probably consume.

For instance, watermelon falls within the group of foods to avoid with a GI value of 80. However, a typical portion of watermelon contains only a little amount of digestible carbs. So, consuming a lot of watermelon won’t drastically increase your blood sugar levels.

Glycemic load (GL), a numerical measure that represents the change in blood glucose levels after you eat a standard serving of the food, was created by researchers as a solution to this issue. For instance, watermelon, which has a GL value of 5, has a serving size of 4.2 ounces (120 grams, or 3/4 cup), making it a healthy food option. For instance, a serving of raw carrots weighing 2.8 ounces (80 grams, or 2/3 cup) has a GL value of 2.

Sydney University’s table of GI values also includes GL values. The values are generally grouped in the following manner:

  • Low GL: 1 to 10
  • Medium GL: 11 to 19
  • High GL: 20 or more

Other issues

We can learn nothing about other nutritional data from a GI value. One cup (250 milliliters) of whole milk, for instance, has a GI value of 31 and a GL value of 4. Whole milk is not the ideal option for weight reduction or weight control, nevertheless, due to its high fat content.

The published GI database is a list of foods that have been investigated rather than an entire list of all foods. The database does not include a lot of wholesome foods with low GI levels.

Any food item’s GI value is influenced by a number of elements, such as how it is made, how it is processed, and what other foods are consumed at the same time.

Some people contend that the fact that GI ratings for the same meals might vary makes it an unreliable tool for making dietary decisions.

Diet details

A GI diet prescribes meals primarily of foods that have low values. Examples of foods with low, middle and high GI values include the following:

  • Low GI: Green vegetables, most fruits, raw carrots, kidney beans, chickpeas, lentils and bran breakfast cereals
  • Medium GI: Sweet corn, bananas, raw pineapple, raisins, oat breakfast cereals, and multigrain, oat bran or rye bread
  • High GI: White rice, white bread and potatoes

Commercial GI diets may describe foods as having slow carbs or fast carbs. In general, foods with a low GI value are digested and absorbed relatively slowly, and those with high values are absorbed quickly.

Commercial GI diets have varying recommendations for portion size, as well as protein and fat consumption.


Depending on your health goals, studies of the benefits of GI diets have produced mixed results.

Weight loss

In 2015, findings from a 16-year research that monitored the diets of 120,000 men and women were released. Researchers discovered that high GL diets derived from consuming refined cereals, starches, and sugars were linked to greater weight gain.

According to other studies, a low GI diet may also encourage and support weight loss and weight maintenance. Data from a different study, however, showed a wide variation in people’s GI scores for the identical items. When making dietary selections, the GI values’ wide range of fluctuation renders them an unreliable guidance.

Blood glucose control

According to studies, the total amount of carbohydrates in a meal predicts blood sugar response more accurately than the GI. According to the research, carbohydrate counting is the most effective strategy for regulating blood glucose in the majority of diabetics.

However, the observed effects may also be due to the low-calorie, high-fiber content of the diets recommended in the study. Some clinical studies have suggested that a low-GI diet may assist persons with diabetes control blood glucose levels.


Reviews of trials measuring the impact of low-GI index diets on cholesterol have shown fairly consistent evidence that such diets may help lower total cholesterol, as well as low-density lipoproteins (the “bad” cholesterol) — especially when a low-GI diet is combined with an increase in dietary fiber. Low- to moderate-GI foods such as fruits, vegetables and whole grains are generally good sources of fiber.

Appetite control

An appetite-controlling effect of a low-GI diet is one notion. According to the theory, eating foods with a high glycemic index induces a quick rise in blood sugar, a quick insulin response, and a quick return to hunger. In turn, eating low-GI meals would postpone hunger pangs. Clinical tests of this notion have yielded conflicting findings.

Additionally, if a low-GI diet reduces appetite, a long-term effect should be that people choose to eat less and better control their weight as a result. However, the long-term clinical evidence does not support this impact.

What Is A Low Glycemic Diet Plan?

A low glycemic index diet can be a useful tactic if you’re seeking for a nutritionally balanced way to reduce weight. It contains a lot of fruits, vegetables, lean meats like fish and chicken breast, as well as whole grains like rice, oats, and barley. This kind of diet promotes healthy eating by releasing glucose into your bloodstream gradually, preventing spikes and drops that might otherwise cause you to feel hungry again soon after eating.

Over time, eating meals with a low glycemic index will help to maintain stable blood sugar levels, reducing the need to overeat or snack frequently. You’ll find it simpler to stick to this kind of meal plan after you get used to reading food labels.

On a low GI diet, any item is fine in moderation, but it’s crucial to be aware of which foods are higher and lower on the scale so that you can make informed decisions.

Which Foods Should You Eat On A Low GI Diet?

Low GI diets can be hard to stick to simply because most people don’t know what the GI ratings of the foods they are eating really are.

This diet requires you to:

  • Eat mainly low-GI carbs (score of 55 and below) such as oats, barley, butter beans, peas, non-starchy vegetables, milk, sweet potatoes, and most fruits.
  • Eat smaller amounts of medium-GI carbs (56-69) such as brown rice, couscous, wholemeal bread, rye bread, quick oats, honey, and orange juice.
  • Avoid, or mostly nibble on high-GI carbs (70 and above) such as russet potatoes, white bread, cookies, instant pasta, short-grain white rice, pineapples, and melons.

What Factors Affect The GI Score?

The list of carbs and their scores is available online, from sources such as the University of Sydney’s GI-testing lab. However, it’s impossible to find a GI ranking for every food; researchers can’t test them all. This is especially true because many factors influence a food’s GI score, including (2):

  • Level of processing: Processed carbohydrates tend to have higher GI scores than whole ones.
  • Ripeness: Sugar in fruit breaks down as the fruit ripens, increasing the GI score.
  • Preparation: Some cooking processes break down carbohydrates and increase the meal’s GI score.
  • Dressing: Using acidic seasonings, such as lemon or vinegar, lowers a meal’s GI score.
  • Type of starch: Amylose has a lower GI score than amylopectin.

What Are The Benefits Of A Low Glycemic Diet Plan?

Eating items with a lower GI rating in smaller amounts is the secret to a low glycemic diet. This reduces your sugar intake and makes you feel fuller for longer, which lowers your calorie intake and results in a calorie deficit. This kind of dietary routine can lead to weight loss.

An increase in fiber consumption, a reduction in overall calorie intake, a reduction in blood sugar levels, and an increase in muscle mass are all advantages of such a strategy in addition to calorie reduction.

More Efficient Fat Burning

Your body receives a signal when you eat carbohydrates to release insulin to make sure glucose is taken into cells. Blood sugar levels become unstable as a result, which encourages the development of more glycogen (the form of glucose used for storage) and inhibits fat burning. This whole thing prevents weight reduction.

Experts are unsure of why carbs have less of an effect on weight, but they do believe that a low glycemic diet burns fat from the body as effectively as a high GI diet does. They speculate that this might be because of fewer hunger pangs while following such a diet, or because insulin sensitivity rises as GI levels fall.

Low Glycemic Diets And Hormone Levels

The glycemic index rating of a food is determined by how quickly it increases after consumption, as was previously indicated. And because of this, insulin is crucial to its impact on hormone levels. Because insulin is also referred to as the hormone that promotes fat storage, controlling blood sugar levels is crucial to any weight loss program.

According to research, eating a low-GI diet may help to enhance levels of sex hormones like testosterone, while eating a high-GI diet may raise levels of cortisol (the stress hormone). The former may be a factor in weight gain, therefore reducing it may be one way low GI foods can aid in weight loss more successfully than other diets.

Low Glycemic Index Diets And Muscle Mass

You must provide your body enough amino acids—the protein’s building blocks—in order to increase lean muscle mass or improve muscular tone. Dietary proteins contain these nutrients.

Low glycemic diets, according to researchers, boost the amount of essential nutrients that enter the bloodstream, improving muscular health and athletic performance.

Consuming a lot of carbohydrates causes your body to convert them into glucose molecules, which elevates blood sugar levels and inhibits the formation of ketone bodies from fat metabolism.

Is A Low GI Diet Good For Weight Loss?

A low GI diet is a diet that limits the number of foods with a high glycaemic index and aims to increase the number of foods with low GI. The idea behind this is that these kinds of diets help you lose weight by helping you feel fuller for longer periods, which lowers your calorie intake in the long run.

However, following the low glycemic diet consistently to lose weight is easier said than done because:

  • You have to do all the research – other than to eat low-GI foods, there are no rules for this diet. Without the structure, you have to figure out how much, what, and when to eat. 
  • You might not find all the information you need – aside from the fact that not all foods are in the GI database, there are too many factors that affect a food’s ranking. Coming up with an estimate of the effect of every food on your blood sugar might be impossible. 
  • Low-GI doesn’t always equal healthy – using the glycaemic index to decide whether foods or combinations of foods are healthy can be misleading. For example, watermelon and parsnips are high GI foods, while chocolate cake has a lower GI value. Potato chips have a lower GI than potatoes cooked without fat.

Is A Low GI Diet Good For Diabetes?

There is evidence to show that a low glycemic index diet will enhance your health if you have diabetes and are managing it with prescription medication.

As part of a diabetes diet plan, consuming foods with a low glycemic index can help regulate blood glucose. The amount of carbohydrates you consume, as opposed to their GI rating, has been found to have a greater impact on blood sugar levels. Additionally, making modifications to one’s diet and lifestyle in addition to choosing low-glycemic foods is necessary for treating diabetes.

How Can A Low GI Diet Help Improve Heart Health?

A low glycemic index (GI) diet’s main goal is to reduce blood sugar levels, but it can also be good for your heart. A low GI diet may help to avoid or reduce several risk factors for heart disease, such as excessive cholesterol and high blood pressure, by maintaining blood sugar levels in check.

Foods with a low glycemic index are typically abundant in fiber and other heart-healthy elements. For instance, many meals high in fiber also have low amounts of saturated fat, a type of fat that can increase cholesterol levels. Additionally, fiber may lessen inflammation and assist in controlling blood sugar levels, both of which are advantageous for the heart.

A low GI diet can also aid in weight loss or healthy weight maintenance. Obesity or being overweight is a significant risk factor for heart disease. By making you feel full after eating and assisting in blood sugar control, a low GI diet may aid in weight loss.

Last but not least, eating a low GI diet is a healthy way to eat generally. A range of nutrient-dense foods, including fruits, vegetables, whole grains, and lean protein, are included in this type of eating regimen. A diet that is heart-healthy should include all of these foods.

How To Get The Most Out Of Your Low GI Diet Plan?

Here are a few brief suggestions to help you maximize the benefits of your low-glycemic food plan:

Eat regularly — Eating three to four smaller meals and two to three snacks per day maintains your blood sugar constant throughout the day and enables your body to manufacture insulin more gradually than if you have many little snacks. At every meal, you can blend various food categories rather than sticking to just one. A turkey sandwich with low-fat cheese and salad, for instance, would be a smart choice.

Eat slowly and take your time to ensure that the food is properly chewed and enters the GI system at a slower rate.

Go for the protein! Including high-quality lean proteins in your diet, such as chicken breast or fish, will help you lose weight and develop muscle. Nuts, seeds, and beans are excellent sources of plant-based protein for vegetarians. To limit your intake of fat, make sure to buy lean meat cuts or poultry with the fat removed.

Despite their convenience, low-GI processed foods tend to be heavy in fat and calories, so consuming too many of them might throw your diet off course.

Keep it simple; the less you have to consider while deciding what to eat, the better. Keep it simple by eating baked fish or chicken, salads (without dressing), whole-grain pasta, fruit, veggies, dried beans, or lentils.
