Summary

This randomized controlled study evaluated the effects of diet, exercise, and electrical muscle stimulation (EMS) on body measurements, blood test results, and appetite in women with overweight or obesity.

A total of 75 women aged 19-45 years with a body mass index (BMI) of 25 kg/m² or higher were randomly assigned to one of three groups: diet alone, diet plus exercise, or diet plus EMS. All participants received an individualized energy-restricted diet. Participants in the exercise group also performed at least 30 minutes of moderate-intensity walking daily, while participants in the EMS group received abdominal EMS twice per week for six weeks.

Body measurements, selected biochemical parameters, and appetite-related measures, including hunger, satiety, and desire to eat, were assessed before and after the six-week intervention. The study aimed to determine whether adding exercise or EMS to an individualized energy-restricted diet provides additional benefits for body composition, metabolic health, and appetite regulation in women with overweight or obesity.

Conditions

  • Obesity & Overweight

Interventions

BEHAVIORAL

Individualized Energy-Restricted Diet

Participants received an individualized energy-restricted diet designed to provide an energy deficit of approximately 500 kcal/day. The diet provided 55-60% of total energy from carbohydrates, 12-15% from protein, and 25-30% from fat, with a target fiber intake of 25-30 g/day. Participants attended weekly follow-up visits throughout the 6-week intervention period.

BEHAVIORAL

Moderate-Intensity Walking

Participants were instructed to perform at least 30 minutes of moderate-intensity walking daily throughout the 6-week intervention period. Walking intensity was defined as producing a slight increase in heart rate and breathing while allowing participants to maintain conversation comfortably.

DEVICE

Electrical Muscle Stimulation (EMS)

Localized abdominal electrical muscle stimulation was administered twice weekly on non-consecutive days for 6 weeks, for a total of 12 sessions. Each session lasted approximately 25 minutes. Four surface electrodes were positioned symmetrically on the abdominal region. Stimulation was delivered at 85 Hz with a pulse width of approximately 300-400 μs, and intensity was increased according to individual tolerance to achieve visible and palpable muscle contractions without pain or discomfort.
