The goal of this clinical trial is to evaluate the effects of spirulina platensis supplementation and calorie restriction on anthropometric parameters, body composition, lipid profile, insulin resistance, serum superoxide dismutase (SOD) levels, and serum malondialdehyde (MDA) levels in men with obesity. The main question it aims to answer are:

What is the effect of spirulina platensis supplementation and calorie restriction on anthropometric parameters, body composition, lipid profile, insulin resistance, serum Superoxide Dismutase levels, and serum Malondialdehyde levels in obese individuals?

Participants will be respondents were given spirulina supplements for 30 days with a dose of 2x2 capsules 450mg

Researchers will compare intervention group with placebo group that weren't given spirulina supplementation to see if there is any effects on anthropometric parameters, body composition, lipid profile, insulin resistance, serum Superoxide Dismutase levels, and serum Malondialdehyde levels

Spirulina supplement intervention on subjects with male gender aged 25-55 years, which will be intervened for 4 weeks / 30 days, before the intervention will be taken anthropometric parameters, body composition, lipid profile, insulin resistance, serum Superoxide Dismutase levels, and serum Malondialdehyde levels.

After that, spirulina supplement intervention will be given at a dose of 2x2 / day, and follow-up will be carried out every week, after 30 hours of intervention,spirulina supplement distribution is carried out by research assistants every 2 days.

Will be taken again to conduct anthropometric parameters, body composition, lipid profile, insulin resistance, serum Superoxide Dismutase levels, and serum Malondialdehyde levels.

The aim is to find out if there is an effect of spirulina supplementation on anthropometric parameters, body composition, lipid profile, insulin resistance, serum Superoxide Dismutase levels, and serum Malondialdehyde levels.
