A keto or low-carb lifestyle can be very effective for achieving and maintaining a healthy weight. In addition to increasing fat burning and reducing insulin and blood sugar levels, very-low-carb diets help control appetite and promote satiety, which often leads to a spontaneous reduction in calorie intake. However, plateaus are common during weight loss, regardless of diet. In fact, there are some foods that are technically allowed on a keto diet yet may lead to plateaus or stalls.
Here is a list of 7 keto and low-carb foods that can cause weight loss plateaus.
1. Bulletproof Coffee
Bulletproof coffee (BPC) was created by Silicon Valley “biohacker” Dave Asprey back in 2009 and has become very popular among keto and low-carb enthusiasts. The original ingredients are basic, although over the years there have been several variations. However, most of them are high in calories and fat.
Original BPC recipe:
- 2 cups (500 ml) black Upgraded (Upgraded™) coffee (proprietary low-mold coffee beans)
- 2 Tbsp unsalted grass-fed butter
- 2 Tbsp MCT oil
This recipe provides approximately 400 calories, and many people report that it keeps them full for many hours. Drinking BPC in place of breakfast likely won't cause any problems as long as you make up for the lack of protein, vitamins, and minerals at your other meals.
However, some people may find that consuming bulletproof coffee on a regular basis may cause their weight loss to stall.
Although the effects of replacing a meal with BPC haven't yet been formally studied, research suggests that your body doesn't perceive liquid calories in the same way as solid food that requires chewing, which may lead to higher calorie intake at subsequent meals ( 1, 2, 3, 4).
It's important to note that these studies used higher-carb liquids, so it's possible that BPC's effects on calorie intake later in the day could be different. However, if you drink BPC regularly and are trying to break through a plateau, it may be a good idea to track your intake to see how many calories you're consuming overall.

Nuts are delicious and healthy keto-friendly foods. Most types are low in net carbs yet high in fiber, monounsaturated fats, and important micronutrients like vitamin E, magnesium, and potassium. However, they're also fairly high in calories, and many people find it difficult to eat only a few at a time.
In fact, Dr. Atkins didn't allow nuts in the initial Induction phase of the Atkins diet in order to promote maximal weight loss. And he believed that nuts should be among the first foods to go when stalls or plateaus occurred.
If you're sticking to your carb limit yet not seeing any weight loss, try limiting your nut intake to an ounce (28 grams) per day, or even avoiding them altogether until you begin losing again.
Here is what a 28-gram serving of different nuts looks like:
- 22-24 almonds
- 8 medium Brazil nuts (see note below)
- 12 hazelnuts
- 12 macadamia nuts
- 35 peanuts (technically a legume)
- 15 pecan halves
- 49 pistachios
- 14 walnut halves
Note: Brazil nuts are extremely high in selenium, so it's best to limit them to 2-3 per day in order to prevent toxicity.

Like nuts, cheese is another healthy, satisfying low-carb food that can be difficult to consume in small amounts.
Although studies have failed to show a relationship between high-fat dairy foods and weight gain, it's notorious for causing weight loss plateaus in some who follow keto and low-carb diets. Indeed, anecdotes abound of people losing weight after removing cheese from their diets following stalls of several weeks or even months.
Although its effects on weight don't appear to be universal, some people seem particularly sensitive to the insulin-raising effects of casein and whey in cheese. This response—coupled with cheese's delicious taste that make it easy to overindulge in—can lead to weight loss difficulty in susceptible individuals.
To break through a plateau, consider limiting cheese to a 1-ounce (28-gram) serving twice a week if you don't want to give it up altogether.

4. Processed Low-Carb and Keto Foods
Commercial low-carb meals, bars, and other products may seem like an ideal option for busy people who follow a keto lifestyle for weight loss.
However, to take off weight healthfully and sustainably, both carb content and food quality matter. Unfortunately, as this way of eating continues to grow in popularity, many products with questionable ingredients are being marketed to the public as “keto” or “low carb,” and some of them may interfere with weight loss.
Here are just a few examples of the countless list of processed "keto" or "low-carb" products:
Dr. Atkins was ahead of his time when it came to carb restriction and whole foods nutrition, but the company that bears his name today uses several less-than-healthy ingredients in their products. For instance, their Pepperoni Pizza and other frozen entrees contain soy, wheat, maltodextrin, and cornstarch.
Some Atkins bars like Cookies n' Creme are sweetened with maltitol, a sugar alcohol that can be partially absorbed and raise blood sugar, whereas the White Chocolate Macadamia Nut Bar and others contain added sugar.
Many One Bars contain a blend of maltitol, sugar, and isomalto-oligosaccharides (IMOs). In studies, IMOs have been found to raise blood sugar and insulin levels (5, 6). Although responses seem to vary from person to person, it's possible that consuming this sort of product could cause problems from a weight loss standpoint.

If you eat processed low-carb products, it's important to read the ingredients labels to see what they actually contain rather than rely on the often misleading “net carbs” listed by the manufacturer. Moreover, avoiding or strictly limiting all types of processed convenience foods and focusing on fresh, whole food may help you start losing weight again.
5. Added Fats
Keto and low-carb diets are typically high in fat. Generally speaking, low-carb diets contain more than 50% of calories as fat, and keto diets provides about 65-80% of calories as fat.
In recent years, the notion that increasing fat intake will promote weight loss has been circulated among the online keto and low carb community. However, this isn't true. In fact, adding too much fat to your food can backfire.
In order to lose weight, you need to create a calorie deficit. Including large amounts of butter, cream, and oil in your diet will cause you to burn more fat—but it will be the fat you're eating rather than your own body fat.
If you routinely add a lot of fat to meat, fish, avocados, and similar fatty foods, you're likely to experience weight loss plateaus. Limiting added fats to a couple of tablespoons of dressing on salad and using a small amount of butter or oil for cooking may help you get the scale moving in the right direction.
6. Alcoholic Beverages
Alcohol can usually be enjoyed on a low-carb or keto diet when consumed in moderate amounts. However, drinking alcoholic beverages can also slow down weight loss in certain cases. Alcohol is another low-carb item that Dr. Atkins didn't allow at the beginning of his diet and removed during weight loss plateaus.
In addition to potentially interfering with ketosis and promoting fat storage when consumed too often, alcohol relaxes inhibitions around food, making it more likely to overeat and choose foods you might normally steer clear of.
Consider limiting your alcohol intake to one or two drinks a week until you begin losing weight again.
7. Homemade Keto Treats
There's no shortage of recipes for low-carb and keto desserts and treats available online. The majority of them are gluten free, sugar free, and don't contain any of the questionable additives found in many processed low-carb products. In addition, these creations appear to be delicious, easy to prepare, and the perfect solution to cravings for sweets. In many cases, they are all of these things. However, they can sometimes lead to weight loss stalls.
Having keto-friendy treats on hand is great for parties and celebrations, but when they're around all the time, you tend to eat more of them than you realize. Even if they only contain a carb or two per serving, those carbs can add up quickly, as can their calories.
During a weight loss plateau, keto treats should only be consumed in limited amounts, if at all. You don't have to give them up forever, but when losing weight is your goal, try to focus on eating as cleanly as possible, sticking to protein, vegetables, and healthy fats.
Take Home Message
Weight loss plateaus can be very frustrating when you're consistently staying on plan yet not achieving the results you're after.
However, some keto and low-carb foods are more weight-loss-friendly than others. Additionally, some people can handle more of certain foods than others without it affecting their progress. Therefore, it's important to experiment to find out how much of these foods you can handle, if any.
Although it may be tough to give up some of your favorite foods, keep in mind that it may only be temporary. It's entirely possible that you'll be able to introduce them back into your keto lifestyle at some point once you've broken through the stall.
Above all, try not to succumb to extreme measures like eating only one food or fasting for several days in a row. If you eat healthy, well-balanced keto or low-carb meals, stay active, and manage stress, rest assured that you will eventually begin losing weight again.
