Top Slow Carb Foods for Weight Loss

Before we talk about “good” or slow carb foods, let’s review the 10 worst possible sources of “bad” carbs. If you’re eating these as a significant part of a regular diet, your weight loss goals are probably doomed, yet replacing them with slow carbs could bring about lasting weight loss.

These are all common sources of quick-release carbs that cause your blood sugar to surge, otherwise known as High-GI (Glycemic Index) or “fast carbs”.

The 10 Worst Possible Sources of Carbs

  • Soda
  • Beer
  • Candy
  • Cereals containing sugar
  • Breading on fried foods or Skillet “Helper” mixes
  • White bread
  • White rice
  • White potatoes (baked, mashed, French fries, chips)
  • Noodles/pasta
  • Baked goods (cakes, doughnuts, cookies, etc)

“Recent animal research provides compelling evidence that high-GI carbohydrate is associated with increased risk of obesity. In one study, male rats were split into high- and low-GI groups over 18 weeks while mean body weight was maintained. Rats fed the high-GI diet were 71% fatter and had 8% less lean body mass than the low-GI group.” link to study

You NEED Carbs – The Right Carbs

Let’s sneak in a mini-nutrition lesson here. You need carbs, because they provide your body with energy. The problem is that excess carbs are stored as fat.

So we want carbs that move slowly from your stomach and through your small intestine, being digested (converted by your body to glucose) gradually so that the fuel they provide is a steady flow instead of a spike.

This means the key to slow carbs is to find nutritious foods with ALL of these qualities:

  • Low GI (glycemic index) ratings – no blood sugar surges
  • High fiber
  • Slow digestion

You’ll notice that the “bad carb” foods listed above have the opposite of these qualities. They’re all high GI, low in dietary fiber, and digested quickly – a recipe for building body fat.

So What Foods Are Slow Carbs?

The concept of slow carbs was popularized by Tim Ferris, author of The Four Hour Work Week.  Slow carbs help you feel full longer, so they’re a great assist to those who are trying to lose weight and keep it off. They also keep your blood sugar levels more stable between meals, which helps prevent chronic diseases.


beans and lentils are great slow carbsThe USDA recommends that legumes be consumed several times per week.

They’re nutritionally dense, high in protein and fiber, and offer sufficient calories in a serving to keep your body fuelled. They digest slowly and are excellent at preventing blood sugar surges. Very low on the Glycemic Index, they’re a staple of slow-carb diets, and can be prepared in many ways. Choices include:

  • Beans (white, black, pink, kidney, pinto, black-eyed, great northern, navy, chickpea)
  • Lentils
  • Green Beans
  • Peas


slow carb foods with each meal help weight lossAll non-starchy vegetables contain slow-release carbohydrates.

Pretty much any green vegetable is a good choice, but avoid starchy vegetables such as white potatoes and corn which contain quick-release carbs – for example, a baked or mashed potatoe scores a GI of 85.

Good slow carb choices include:

  • Asparagus – A tasty treat that can be roasted, steamed, sautéed, pickled or added to a salad, asparagus has a Glycemic Index of only 15 and lots of fiber.
  • Cabbage – Cooked or raw, cabbage is another low GI vegetable with a rating of 15. It’s high in fiber and Vitamin C.
  • Broccoli – Another vegetable with a GI of 15, broccoli has lots of vitamins.
  • Cauliflower – A low GI vegetable with a GI of 15, cauliflower can be easily substituted for high-GI white rice or mashed potatoes.
  • Celery – With a GI of only 15, celery has long been known for “negative calories”, in that it is said it takes more energy to chew and digest it than you get from eating it.
  • Cucumber – Tasty raw or pickled, cucumber’s GI of 15 makes it another low-carb favorite.
  • Spinach – Another GI 15 vegetable, spinach is a powerhouse of nutrients and a key ingredient in our supernutrient green smoothie. It can be eaten raw or cooked.


I’ve written elsewhere about how the superfood Quinoa has extraordinary nutrition, and a high satiating index that really helps dieters. It’s also a slow carb staple with a GI of 35, considered low on the GI Index.

Steel Cut Oatmeal

Steel cut oatmeal (GI 42) is an excellent slow carb breakfast. Add a couple of teaspoons of chia seed or hemp hearts to really boost its nutrition.

It’s About Lifestyle Choices

    I am caught red handed and I am guilty when it comes to eating those bad sugary carbs. I’ve been thinking a lot lately about restricting food with high sugars from my diet. I’m trying to stay away from Soda, chips, candy, cake, cookies, and etc. I just need to find healthier substitutes to eat at home and when I’m on the go. After I finish school, I go to my after school program in which finding a healthy snack with good carbs can be hard to find and I usually settle for a snack from my local corner store. Even so, I am looking for healthier snacks in store. Learning about these slow carbs are really inspiring and can be useful to my diet. I can’t wait to adjust to the healthier changes.

      Unfortunately, you’re not going to find “good snacks” in a convenience store very often. One of there reasons that sugar is so pervasive, OTHER than its addictive qualities, is that it’s good at preserving food. The processed carbs, sugars and chemicals in most convenience food snacks give them long shelf life… and poor nutritonal quality. That’s why learning to plan ahead for healthy snacks is so important.
