Overweight and obesity affect around 2 in 3 adults in the United States. People with these conditions are at an increased risk of diabetes, heart disease, and other health conditions.

Adopting a healthy diet and engaging in regular physical activity can help people reach their health and fitness goals.

One study found that adults who used a smartphone app alongside a weight loss program lost more weight than those who took on the weight loss program alone.

A 2020 systematic review of the effectiveness of weight management apps states that people perceive their eating habits and weight loss to be better while using the apps.

Additionally, the researchers suggest that these apps have several benefits as a low-intensity form of weight management, such as:

However, the review also notes that people may find it difficult to stay motivated when using weight loss apps. Some potential reasons for loss of motivation include a lack of time or energy and seeing slow results. People may also stop using an app to avoid negative attention for not sticking to a meal plan.

Here we answer some common questions about these apps.

Do weight loss apps really work?

According to recent research, weight loss apps may be beneficial as a low intensity weight loss approach, or alongside other weight loss therapy.

However, the researchers note that there is insufficient evidence to support the use of weight loss apps as a stand-alone therapy for weight management.

How much water should I drink per day to lose weight?

Worldwide, 16—28% of adults have dehydration.

The Institute of Medicine recommends adult males consume 3.3 liters of water per day, and adult women drink 2.3 liters. This consumption can partially come from a person’s daily food intake.

How do I know if I need to lose weight?

According to the National Institute of Diabetes and Digestive and Kidney Diseases, over 30% of Americans have overweight, over 42% have obesity, and over 9% have severe obesity.

A fast way to check whether a person may need to lose weight is by using a BMI calculator. Adults with a BMI of 25 and over may need to take steps to manage their weight.
