This does not mean that there is any food that can specifically protect you from developing diabetes.

What Are The Foods That Lower Blood Sugar Instantly Without Insulin?

According to Medical News Today, most of the recommended foods for people with diabetes have a low glycemic index (GI). The body absorbs the carbohydrates in such foods slowly, reducing the possibility of causing spikes and dips in blood sugar (1). People who want to lower or control their blood sugar levels should pick foods with low or medium GI scores.

But it is worth noting that there is no food that can help lower blood sugar immediately. High blood sugar levels are influenced by several factors, including your health and medications (4). Your diet impacts your blood sugar levels, and making changes to your diet helps control your blood sugar levels over time, but won’t necessarily cause an instant drop. 

It would be best to consult your doctor on the best and instant strategies to manage high blood sugar levels. In addition to dietary changes, regular exercise (if safe for you) can help lower blood sugar levels. In some cases, doctors recommend using insulin because it reduces blood sugar quickly. However, it is worth noting that there are different types of insulin, each with a varying onset and duration.

Foods That Help Control Blood Sugar/Glucose Levels

As we have determined above, there are no foods that lower blood sugar instantly. With that in mind, you are still warranted to limit high GI foods and focus on low or medium GI foods, because that strategy can help you lower your blood sugar levels over time. If you are wondering what these foods are that help lower blood sugars over time, here they are:

Pumpernickel Bread Or Stone-Ground Whole Wheat

One of the kinds of foods people with diabetes are advised to avoid is many kinds of bread and other refined grain products due to their high GI scores. Instead of those, they are urged to replace them with whole grain foods which are higher in fiber (1).

Two great whole grain foods to consider are pumpernickel bread and 100% stone-ground whole wheat bread. According to Medical News Today, these two foods have low GI scores at 55 or below, unlike regular white wheat bread (1).

Other excellent whole grain food options are rye and spelt. You can also opt for bread made with ancient grains like emmer and einkorn or other whole grains (1).


Recent evidence suggests that berries contain several nutrients and phytochemicals that may reduce the risks of several chronic diseases, including type 2 diabetes (2). In addition, a 2020 review mentioned that commonly consumed berries, especially blueberries, cranberries, raspberries and strawberries, may help limit the after-meal rise in blood sugar in individuals with insulin resistance.

According to the review, non-acute long-term studies show that berries can improve glycemic and lipid profiles, blood pressure and the surrogate markers of atherosclerosis (2). However, though sparse, existing evidence also suggests that berries have an emerging role in dietary strategies for diabetes prevention and preventing diabetes complications in adults (2). Nevertheless, berries must be consumed as part of a healthy and balanced diet for diabetes prevention and management.

Sweet Potatoes

Sweet potatoes have a glycemic index of 55 and lower. The low glycemic index and high fiber content result in a less immediate impact on blood glucose levels when consumed (7). It is worth noting that the index can change depending on your chosen cooking method.

For people with diabetes, boiling is the best way to cook sweet potatoes because it maintains their low GI. However, baking, roasting, and frying increase the GI (6). 


Quinoa can help lower your blood sugar levels when added to a diabetes meal plan. This is because it has a low glycemic index of 53 (5). Additionally, it has high fiber content, which is crucial in helping adjust a person’s blood sugar.

According to Medical News Today, 100 g of quinoa contains 2.1 g of fiber, while the same serving of white rice has zero (5). This means quinoa is a better choice for people with diabetes than white rice.

I've struggled to maintain programs…

I've struggled to maintain programs before, but somehow I've been able to stick with this. I enjoy the workouts and have made healthy changes to my diet with the challenges. Its nice for something to really have stuck and worked. I did the sugar free challenge and it's really changed how I relate to the signals my body is giving me about the food I'm eating.

Our Journey

This has been an awesome journey for my wife and I. Not only are we losing weight , but we are living a new life style. Our eating habits have been reformed by following the meal plan and our bodies have become stronger by simply doing the ten minute, sometimes twenty minute workouts. It really has been easy and convenient to transition into a healthier routine and has truly re energized our lives moving forward into the future.

It Works! This program is working for me!

lynne R.
This program is working for me! After a little over a month, I have lost 10 pounds. Slow, but steady. Guided exercises are done daily and there is an option to do other routines beside the one chosen for the day. It is very helpful having the recipes for all meals plus a snack. Would like if we could know the ingredients the day before. Makes preparing alot easier. I like the fact that alternative foods are suggested in case you can't eat(or don't like) the recipes listed. This is a very good program. Stick to it and YOU will see results. I have!
