6 min reading time

The low GI diet plan allows you to choose meals that don’t raise your blood sugar levels, and it isn’t wholly restrictive hence becoming one of the best weight loss meal plans.

This meal plan is based on the glycemic index scale and doesn’t wholly exclude any food groups. The theory is that these diets assist in weight loss by making you feel filled for extended periods, ultimately reducing your calorie intake.

Based on three weeks of research, this article will help guide you on how to start a low GI diet, what foods to eat, what to avoid, benefits, drawbacks, and a 7-day low glycemic diet plan to get you started.

What is Low GI Diet Plan?

The low glycemic index diet is an eating plan based primarily or exclusively on a glycemic index system. This diet considers how various foods influence your blood sugar levels.

The glycemic index categorizes foods based on their blood sugar levels. The rates at which foods raise the blood sugar level are compared with the absorption of 50 grams of pure glucose. In the GI ratings, foods are either low (55 or lower), medium (56-69), or high (70 or more).

A glycemic index diet, unlike some other plans, may not always specify serving sizes or the ideal caloric, carbohydrate, or fat intake for weight loss or maintenance.

Foods with a low GI are more preferred in the low GI diet plan as they only raise a small number of sugar levels, unlike high GI foods.

A glycemic index (GI) diet aims to eat carbohydrate-containing foods that are less likely to cause significant increases in blood sugar levels. In other words, a low GI diet entails replacing high GI foods with common GI substitutes.

People take the GI diet plan for various reasons, including; wanting to shed weight or to maintain an average blood sugar level.

Why You Should Take Low GI Diets

  • A Low GI diet helps in promoting and maintaining weight loss.
  • A low GI diet helps maintain blood glucose levels, especially in people with diabetes.
  • A low-GI diet can help lower the body’s total cholesterol level when combined with dietary fibre foods like fruits and vegetables.

Limitations of the Low GI Diet

The low GI diet doesn’t consider other foods, like protein or fibre. As a result, some foods can have low GI value yet still be unhealthy.

The GI diet meal is difficult to calculate when foods are consumed as part of a larger meal. This method is usually less effective.

In the GI index, only foods that do not contain carbohydrates have a GI value. This is usually ineffective as carb content is an essential factor to use in determining blood sugar levels. This method is better used in combination with counting calories or checking other compositions of the foods.
