Changing eating habits are hard and even harder when hearing about all the diets available. There’s a lot of online buzz about low carb diets.
Some say they are amazing for weight loss. Others warn that they can increase your risk of heart disease. And who isn’t managing moods with carbohydrates? Craving carbs may lead to a big bowl of pasta or the heel of homemade bread slathered in butter!
So, what is it?
Low-carb diets may help some people lose weight and/or manage their blood sugar levels. And they may do these (slightly) better than low-fat diets. And yet the low carb diets, energy fizzles out and then workouts are that much harder, and weight loss plateaus.
And… managing moods with carbohydrates too?
Let’s first figure out what exactly a low-carb diet is and whether it’s something you should consider… or not. Learn how to eat just the right amount of carbohydrates by working with a Registered Dietitian!
What are Carbs? And are they Bad?
No, carbs aren’t inherently bad (more on this below).
Carb is short for carbohydrates. Carbs are one of the three main macronutrients in the diet. Macro, as in large, means they’re large components of your diet. Just like protein and fat, carbs give us the energy we need for optimal health. Most foods contain two if not all three of these essential macronutrients.
Carbs can definitely be part of a healthy diet. They’re found in many foods that are full of other nutrients like essential vitamins and minerals. Just like fats and proteins, carbs can also be found in nutrient-poor low-quality foods. Medline Plus says, “It is best to get most of your carbohydrates from whole grains, dairy, fruits, and vegetables instead rather than refined grains. In addition to calories, whole foods provide vitamins, minerals, and fibre.”
Similar to other macronutrients, carbs have calories. Eating or drinking too many carbs can add to your daily calorie count—especially if they’re not found foods that are rich in other nutrients.
Effect of Carbohydrates on Your Health
Carbs come in three different shapes and sizes:
● Sugars (found in juices, dairy, sodas, desserts, etc.) are the smallest and are the main type of “fuel” used by your body for energy
● Starches (found in potatoes, grains, legumes, etc.) are broken down into sugars which then go on to be used for energy
● Fibre (found in legumes, vegetables, whole grains, nuts, etc.) provides bulk that helps us feel full and feeds our friendly gut microbes
Different types of carbs have slightly different effects on your body. For example, sugars are, not surprisingly, the least healthy form of carbs. When you ingest sugars they’re absorbed quickly and can cause a “spike” in your blood sugar level. When your body lowers your blood sugar levels a short time later, you may become hungry again and your mood is impaired; feeling “Hangry,” anyone? (So hungry that you’re angry.) Sugar also tends to be found in highly processed and less nutritious foods. People who tend to each more sugars have a higher risk of developing diabetes, heart disease, obesity, and dental cavities.
If you eat carbs as starches it takes a bit more time for them to be broken down into sugars so their effect on your blood sugar level is slower and lasts longer. This is a better option.
Fibres, on the other hand, aren’t digested by us, but rather help us feel full and contribute to a healthy gut by feeding our friendly gut bacteria. People who eat a lot of fibre tend to have a lower risk of heart disease, stroke, and digestive issues.
Possible Benefits of Low-Carbohydrate Diets
Low-carb diets may have a slight advantage for weight loss when compared to low-fat diets. However, studies find that after 12 months, the benefits are not that large.
Low-carb diets may help some people better manage their diabetes, high blood sugar, metabolic syndrome, and heart disease. They may also help improve cholesterol and blood lipids, too.
These may occur not specifically from eating fewer carbs, but rather because of the quality of food choices when eating a low-carb diet as well as from losing some weight.
So… if there is not much of an advantage to low carb diets, what is the secret to managing mood with carbohydrates?
Low-carb diets emphasize eating more of the other two macronutrients: protein and fat. This means more meat, poultry, fish and eggs. It also includes nonstarchy vegetables.
The amount of carb-rich foods would be reduced, although not eliminated. This means eating fewer sweets, grains (e.g., bread, pasta), fruits, starchy vegetables, and legumes.
How low the carbs go isn’t universally agreed upon by dietitians. A typical low-carb diet would recommend no more than 50-150 grams of carbs per day (that’s 200-600 calories per day). This is in contrast with the Recommended Dietary Allowance (RDA) which recommends about 45 to 65% each day from carbs (and for a person on a 2000 calorie diet, that is 225 to 325 g of carbohydrate a day) which keeps the ‘hangry’ feelings away.
Should I Consider a Low-Carbohydrate Diet?
Studies show the overall quality of a food or diet is more important than focusing on just one nutrient, like carbs.
There are a few things to consider.
First, know that if you’re trying to lose weight, low-carb is one of many diets that can help you—at least for a short time. It may take experimentation to find the right one for your genes, metabolism, and lifestyle. It’s very difficult to stick to a diet for the long-term, so finding one that works for you is key or sign up for your discovery call with a registered dietitian.
Be careful when you restrict any major food group, like carbs, for example. This is because you may be restricting key vitamins or minerals. This can lead to deficiencies and long-term concerns like bone loss, gut problems, and chronic diseases.
Because low-carb diets are restrictive cause you to be craving carbs and may not provide all necessary nutrients, this diet isn’t recommended for adolescents or pregnant or breastfeeding women.
Most of the research on low-carb diets is short-term, so we don’t know all the possible health effects of eating like this over the course of many months or years. It’s possible that by eating too much animal food you may increase your risk of heart disease and certain cancers.
Nutrition Tips for Low-Carbohydrate Diets
Remember, there are healthy and not-so-healthy low-carb foods. When replacing carbs with proteins and fats, be sure to choose mood-boosting foods that have quality proteins and fats and a lot of essential vitamins and minerals.
As for proteins, it’s best to get them from poultry, fish, dairy, eggs, nuts and beans, and less from red meats like pork and beef.
When it comes to fats, focus on mood-boosting foods rich in omega-3s and unsaturated fats and choose fewer fats that are saturated and hydrogenated.
If you make drastic changes to your diet you may experience headaches, fatigue, muscle cramps, skin rashes, craving carbs and digestive upsets. Keep an eye out for these and consult an expert if you experience them; and if you need to optimize your diet; get started with a discovery call with a Registered Dietitian today.
If you restrict carbs too much you can change your body’s metabolism and put it into ketosis. This is because your body uses sugar as its main energy source, so when you don’t get a minimum amount of carbs, your body’s metabolism changes to start using fat as its energy source.
If you end up craving carbs, experiencing gut issues or other bothersome symptoms, or simply don’t enjoy eating anymore, a low-carb diet may not be the best one for you.

According to Harvard Health, “The best diet is the one we can maintain for life and is only one piece of a healthy lifestyle. People should aim to eat high-quality, nutritious whole mood-boosting foods, mostly plants (fruits and veggies), and avoid flours, sugars, trans fats, and processed foods (anything in a box).”
