When you’re focused on improving your well-being, it can be challenging to sort through “no-carb,” “low-carb,” or “keto” diets that pledge to improve your health.
But the basics of nutrition are relatively straightforward. Three macronutrients comprise a healthy diet: fats, proteins, and carbohydrates. [1] Ideally, 45 to 65% of your daily energy needs will be fueled by carbs. [2] This category can be broken down further into two types: simple and complex carbohydrates. [1]
The easiest way to understand the difference between simple vs. complex carbs is that while simple carbohydrates are digested rapidly, complex carbohydrates take longer for your digestive system to process. [1] The paces of digestion can have various effects on how your body works. The following guide will explain these, as well as why complex carbohydrates are generally considered healthier.
Your body treats both simple and complex carbohydrates as its primary source of energy. [1] However, the traits and effects on the body differ in several domains [3]:

Both simple and complex carbohydrates can be a part of a healthy diet. However, eaten in excessive amounts, simple carbohydrates can cause:
One of the primary drivers of obesity is a poor diet and a sedentary lifestyle.4 Consuming simple carbohydrates in excess can lead to weight gain and/or obesity. Excess weight and obesity can result in a cascade of related health risks, among them are type 2 diabetes and certain cancers. [4]
For most individuals, it’s possible to adhere to a diet that includes both complex carbohydrates and simple ones (once and a while). However, certain conditions like type 2 diabetes can make simple carbohydrates more risky to consume. [5]
If you’re not sure what types of carbohydrates you can include in your diet, it’s important to consult with a healthcare provider. [5] Learning how to identify between the two is the first step in empowering yourself to make the most supportive food choices possible.
Simple carbs are found in foods like table sugar, honey, fruit, and some refined grains. They also cause a quick blood sugar level spike. A good rule of thumb for spotting simple carbohydrates is to look for foods that are highly processed or manufactured. These include [3]:
If you’re trying to stay away from simple carbohydrates, it’s best to reduce your consumption of food with added sugars. Instead, opt for whole foods or high-fiber, low-carb foods that have been minimally processed.
The produce section (and some aisles) of the grocery store is the best place to stock up on whole, complex carbohydrates.3 These carbohydrates consist of multiple sugar molecules and are found in nutrient-dense foods like whole grains, legumes, vegetables, and some fruits.
Unlike simple carbs, complex carbs take longer to digest and break down into glucose. Look for starchy foods such as [3]:
Arriving at a diet that supports well-being, weight maintenance, and your preferences is highly personal. Some people can consume simple carbohydrate-based foods in moderation without harming their health.6 Others may be more prone to compulsive eating, which may cause health problems down the line. [6] A trusted healthcare provider can be an ally in deciding what boundaries to have around your carbohydrate consumption.
