What is Allulose and How Can It Help You Shed Pounds?

Sugar is one of the most common ingredients in our diet, but also one of the most harmful. Excessive sugar consumption can lead to obesity, diabetes, heart disease, and other chronic health problems. That’s why many people are looking for alternatives to satisfy their sweet tooth without compromising their health.

One of the newest sugar substitutes on the market is allulose, a natural sugar found in small amounts in fruits like figs and raisins. Allulose is chemically similar to fructose, but it is not absorbed by the body and has no calories or carbs. It also tastes very similar to regular sugar, without the bitter or chemical aftertaste of some artificial sweeteners.

But is allulose really a safe and effective option for weight loss? Here are some of the potential benefits and risks of this sweetener, based on the current scientific evidence.

Benefits of Allulose

  • Lower blood sugar and insulin levels. Unlike regular sugar, allulose does not raise blood sugar or insulin levels, which can help prevent or manage diabetes and metabolic syndrome. In fact, some studies suggest that allulose may even lower blood sugar and improve insulin sensitivity in people with prediabetes or type 2 diabetes.
  • Increased fat burning. Allulose may also help boost the body’s ability to burn fat, especially in the abdominal area. A study in the journal Nutrients showed that adults consuming allulose shed more weight than those using sucralose. In fact, people eating allulose (and making no other diet changes) burned 1,134% more belly fat than those using Splenda. Another animal study found that allulose inhibited weight gain and fat accumulation in rats on a high-sugar diet.
  • Reduced appetite and calorie intake. Allulose may also help reduce hunger and cravings, leading to lower calorie intake and weight loss. A study in the British Journal of Nutrition found that allulose reduced appetite and energy intake in healthy adults, compared to sucrose and aspartame. Another study in the Journal of Food Science found that allulose increased the feeling of fullness and reduced the desire to eat in overweight adults, compared to sucrose and maltitol.

Risks of Allulose

  • Gastrointestinal side effects. Like many sugar alcohols and artificial sweeteners, allulose can cause digestive issues such as bloating, gas, diarrhea, and abdominal pain in some people, especially when consumed in large amounts. The FDA recommends limiting the intake of allulose to 0.9 grams per kilogram of body weight per day, which is equivalent to about 60 grams for a 150-pound person.
  • Lack of long-term safety data. Although allulose is considered generally safe by the FDA and other regulatory agencies, there is still a lack of long-term studies on its safety and effects on human health. Most of the studies on allulose have been conducted in animals or in small groups of people for short periods of time. More research is needed to determine the optimal dose, frequency, and duration of allulose consumption, as well as its potential interactions with other medications or supplements.
  • False sense of security. Allulose is not a magic bullet for weight loss. It is still a form of sugar that should be consumed in moderation and as part of a balanced diet. Relying too much on allulose or any other sugar substitute may lead to overeating or neglecting other aspects of nutrition and lifestyle that are essential for weight management and overall health.


Allulose is a natural sugar substitute that has no calories or carbs and may help lower blood sugar, increase fat burning, and reduce appetite. However, it may also cause gastrointestinal side effects, and its long-term safety and efficacy are still uncertain. Therefore, it is advisable to use allulose sparingly and with caution, and consult your doctor before adding it to your diet, especially if you have any medical conditions or allergies. Remember that allulose is not a substitute for a healthy diet and lifestyle, and that the best way to lose weight and stay healthy is to eat a variety of whole foods, limit processed foods and added sugars, and exercise regularly.
