About

Obesity is a growing public health problem in Sweden, but access to care varies depending on geographical location. Eatit´s multimodal digitally dietitian-supported lifestyle intervention offers an accessible treatment alternative, but its clinical effects in practice need to be documented.

The aim of this pilot study is to evaluate the effect of Eatit´s multimodal digitally dietitian-supported lifestyle intervention for weight loss in adults with obesity.

The main question is:

- Does body weight change after six months of using the program?

Secondary questions are:

Does waist size change after six months of using the program?
Do self-rated eating habits improve after six months of using the program?
Does self-rated health improve after six months of using the program?

Participants will use the Eatit program for six months and answer questions about their weight, waist size, eating habits and health. The program integrates behavior change techniques with individualized nutrition counseling provided by licensed dietitians.

During the first three months, participants use Eatit's core program through the app, with weekly support by a dietitian via video calls and text messages.
The core program consists of a weekly reading section combined with a related homework assignment.
After completing the core program, participants continue with monthly video sessions with a dietitian, focusing on the skills that were most helpful during the initial phase or on areas such as receiving support to initiate physical activity.
Weight and waist size are recorded in the app every week.
Questionnaires on eating habits and health are completed at baseline, after three months, and after six months.

Full description

Study design:

- Open-label interventional study conducted within Eatit's routine patient flow, where each participant serves as their own control.

Data sources:

- Data collection to address the research questions regarding treatment effects will be obtained from Eatit's database.

Data to be collected:

-Sex, age, weight, waist circumference, number of completed modules in the digital treatment program, number of completed dietitian visits, as well as results from the self-administered questionnaires Kostindex (Diet Index, developed by the Swedish National Board of Health and Welfare) and World Health Organization Disability Assessment Schedule 2.0, 12-item self-administered version (WHODAS 2.0 12-item).

Recruitment and study participants:

-Five study dietitians will recruit 93 participants through Eatit's routine patient flow. The study population will consist of all eligible individuals who schedule an appointment with a study dietitian, as the aim is to evaluate the treatment effect within Eatit's normal patient population.

Informed consent process:

-The request for study participation is made during Assessment Visit 1, which is conducted by video. If the potential participant expresses interest, the dietitian provides written study information. Inclusion in the study occurs during Assessment Visit 2, after the participant has received both written and verbal information. Participants will be enrolled in the study according to the inclusion criteria, provided that no exclusion criteria are met (see Eligibility). If the participant agrees to take part, informed consent will be obtained digitally.

Intervention:

- Standard care with Eatit's multimodal digital lifestyle intervention program according to routine practice, delivered over six months with dietitian support via chat and video.

Analysis and statistics:

- Descriptive statistics will be used to characterize the study population. Treatment effects will be evaluated using appropriate regression and correlation analyses. Subgroup and dropout analyses are planned. Both intention-to-treat (ITT) and per-protocol (PP) approaches will be applied.

Inclusion criteria

Age 18 years or older
Body mass index (BMI) ≥ 30
BMI 27-30 in combination with at least one of the following:
1. Has received a diagnosis of obesity from another healthcare provider.
2. Has a comorbidity (according to the defined diagnosis list under the heading Comorbidities below).
3. Has central obesity, defined as waist circumference > 80 cm for women or > 94 cm for men.
4. Kostindex score of 4 or lower - eligible for treatment due to increased risk of rapid future weight gain. Dietitian-led intervention may significantly impact weight development in this group.
Ability to read and understand Swedish
Does not currently use, and does not plan to initiate the use of, appetite-suppressing medication
Not pregnant
Patients with BMI > 40, As long as there is no contraindication for treatment, treatment is offered. A dietitian may deny the patient the Eatit program if the dietitian assesses that the need for care is too great, and that Eatit's treatment cannot meet the patient's needs.

Comorbidities:

Cardiovascular disease This is a large group of diagnoses, e.g. previous myocardial infarction or stroke, angina pectoris, heart failure, etc.
Hypertension
Elevated blood pressure, above 130/85 mmHg or ongoing treatment for previously diagnosed hypertension
Hyperlipidemia
Triglyceride levels ≥ 1.7 mmol/L or on treatment for elevated triglycerides, or LDL > 3.0 mmol/L at low risk, or on treatment for high cholesterol, or reduced HDL-C <40 mg/dL for men, <50 mg/dL for women, or on treatment for HDL-C
Obstructive sleep apnea
Type 1 diabetes
Type 2 diabetes
Prediabetes (fasting glucose ≥ 6.1 or HbA1c > 42 without a diabetes diagnosis)
Fatty liver
Polycystic ovary syndrome, PCOS
Osteoarthritis in the lower body (e.g. hip, knee, or foot)

Exclusion criteria

BMI: Patients with BMI < 27 are excluded from treatment.
Medical conditions: Patients with conditions where weight loss or weight gain may worsen the disease are excluded. For example: cancer or chronic obstructive pulmonary disease, COPD.
Multimorbidity: Individuals with extensive comorbidities may have complex healthcare needs requiring more comprehensive medical support than Eatit can provide.
Untreated depression may hinder participation in the program and should be managed with medical or psychological support.
Untreated or ongoing eating disorder (bulimia nervosa, binge eating disorder, anorexia, atypical anorexia, ARFID) should be treated in a specialized eating disorder unit.
Severe psychiatric illness (such as psychosis or schizophrenia) without ongoing support.
Ongoing substance abuse (alcohol, narcotics, or medication) is a contraindication for participation and requires specialized addiction care.
Suicidal behavior or self-harm in the past six months. Acute mental illness requires immediate and specialized interventions.
Requires individual assessment. Certain conditions require individual evaluation as they may negatively affect treatment outcomes. This means that the treating dietitians should ask follow-up questions to ensure that participation in the program is feasible.
Symptoms of binge eating not meeting criteria for binge eating disorder: Ensure that the person is willing to work with the program, not skip meals, and will inform you if the binge eating worsens.
Depression under psychiatric care: Ask follow-up questions about what support the person is receiving and his or her current mental state.
Bipolar disorder: Ask follow-up questions about what support the person is receiving and his or her current mental state.
Exhaustion syndrome/stress: Ask follow-up questions to determine whether treatment is feasible at this time or if the patient needs to manage the stress in other ways first.
Neuropsychiatric disorders: To benefit from the program, sufficient concentration ability and capacity for structure/planning in daily life are required. In case of a neuropsychiatric diagnosis, follow-up questions should be asked about whether the person believes that he or she can manage texts and tasks that take approximately 2-3 hours per week.
High degree of psychiatric comorbidity has in some studies been shown to be a complicating factor, and this should also be considered at the start of treatment. Ask follow-up questions about what support the person is receiving and his or her current mental state.
Severe sleep problems: Sleep deprivation may lead to increased appetite and reduced cognitive capacity, making it difficult to engage with treatment. Ask follow-up questions about possible undiagnosed sleep apnea or potential need for other care to address the sleep problems.
