Timing Matters: When to Stop Eating for Optimal Blood Sugars

Ever wondered if there is an optimal time to cease your evening eating?

Today, I am providing you with expert insights and practical tips to help achieve and maintain optimal blood sugar balance by focusing on meal timing. 

Balancing blood sugars is not just a matter of dietary choices but also about when you eat.

Your eating window, known as the period during which you consume meals and snacks, plays a crucial role in regulating your blood sugar levels. 

Whether you’re navigating the challenges of diabetes, looking to optimize your energy levels or simply curious about the connection between meal timing and blood sugars, this blog is meant for you!

What is Blood Sugar?

Blood sugar, also known as blood glucose, is sugar that circulates in the bloodstream to provide a primary source of energy to your body.

It is essential for proper functioning of various processes and typically levels are tightly regulated. 

Blood sugars can become unbalanced by many different factors such as poor diet, uncontrolled stress, inadequate sleep or inactivity. 

Diabetes and Blood Sugars 

Diabetes is a condition when the body can no longer function to break down carbohydrates normally. 

The pancreas is the organ that plays a vital role in regulating blood sugar levels. To provide your body energy, carbs are broken down into sugars and released into the bloodstream. 

This initiates the pancreas to produce insulin, the hormone that acts as a key to allow sugars from the bloodstream to enter into cells. Energy is provided and your body is able to perform necessary functions. 

With diabetes, your body either doesn’t make enough insulin or cannot use it normally to regulate blood sugars. Over time, glucose builds up in the bloodstream and blood sugar remains high, meeting the criteria for prediabetes or type 2 diabetes. 

What if I don’t have diabetes? 

Maintaining balanced blood sugar levels is essential for everyone. Chronic high blood sugars or hyperglycemia can lead to diabetes while chronically low blood sugar (hypoglycemia) can cause weakness, confusion and fatigue. 

The information that I am about to share in regard to meal timing is applicable whether you have a formal diabetes diagnosis or not. 

As a registered dietitian, I help adults achieve balanced blood sugars to promote overall health. While I primarily work with individuals that have been diagnosed with diabetes, my experience allows me to take clients that are also interested in preventive health.

Blood Sugars and Meal Timing 

When and how often we eat can impact our blood sugars. Consuming meals and snacks consistently can help maintain stable levels while skipping meals can cause blood sugar fluctuations. 

In a study, both men and women that engaged in night eating showed higher rates for obesity than those without this type of eating habit. 

Research also has shown the benefit of daily breakfast intake to reduce the risk of a spectrum of chronic health conditions. 

Striking a balance between the timing of food as well as the composition of the plate can promote optimal blood sugar control. 

Ideal Eating Window 

An ideal eating window is a specific timeframe when you consume all meals and snacks to meet daily nutrient needs. 

This approach allows the body to enter a fasting state outside of the eating window while helping to regulate blood sugar, improve digestion and promote weight management when eating.

Does Eating Window Matter?

Yes! The timing of your meals plays a significant role in blood sugar balance. When you eat can influence how your body processes the food you consume. 

For instance, consuming carbohydrates with breakfast can help jumpstart your energy for the day while a large meal close to bedtime may interfere with sleep quality. 

What time should you stop eating?

Generally, I recommend taking your last bite around 7:30pm then aiming for a 12-hour fasting window. Research shows benefits of fasting include weight management, appetite control, improved insulin sensitivity and cardiovascular health.

If you are hesitant about this eating window due to the fear of increased hunger or eating everything in sight during the day, try implementing these guidelines. 

Choose complex carbohydrates

Opt for whole grains like quinoa, lentils, whole fruits, beans and sweet potatoes over simple carbs at meals and snacks. Complex carbs provide essential vitamins and minerals along with fiber to help slow down the absorption of glucose and prevent blood sugar spikes. 

Create balanced meals

Include sufficient protein, fat and fiber at all meals, especially in the evening. This will allow for stable blood sugars through the night while preventing extreme hunger in the mornings.

Set a meal schedule

Aim to eat meals and snacks at consistent times each day to help regulate blood sugars. This is especially helpful if you have a busy schedule where eating breakfast, lunch or dinner gets put on the back burner. By prioritizing meals, you can consume essential nutrients while also supporting blood sugars. 

Engage in mindful eating

Pay attention to hunger and fullness cues along with triggers that may be impacting your food consumption. By eating slower and bringing an awareness to your meals, you can prevent overeating or undereating.

Hydrate, hydrate, hydrate

Drink plenty of water throughout the day while limiting sugary beverages and alcohol. Adding lemon or limes to your water, choosing sparkling water or enjoying unsweetened herbal tea are additional ways to bump up your hydration. 

Prioritize sleep

Aim for 7-8 hours per night of quality sleep. Lack of sleep can cause abnormal cortisol levels and impact your hunger hormones. 

Move before bed

Physical activity has countless benefits such as improving insulin resistance. Simple movement such as stretching, yoga or walking after eating your last meal can help keep blood sugars balanced throughout the evening.
