Brief summary: The purpose of this study is to evaluate the satiating effects of different canned tuna preserved in olive oil enriched with soluble fiber or polyphenols on overweight subjects (BMI ≥25 and \<30 kg / m2).

Some studies have shown the contribution of high-fiber foods in the reduction of the cardiovascular risk.

Detailed description: A randomized, cross-over and double-blind pilot study with 3 study arms is being performed to evaluate the satiating properties of different canned tuna preserved in olive oil enriched with soluble fiber or polyphenols on overweight subjects.

The investigators included 12 participants (6 men and 6 women) between 18 and 55 years (BMI ≥25 and \<30 kg / m2). All volunteers will be randomized into 3 study groups, and participants will receive the 3 different study products in order during the 3 experimental phases.

Eligibility criteria: Inclusion Criteria:

* Men and women from 18 to 65 years old.
* Body Mass Index (BMI) ≥25 and \<30 kg/m2.
* Adequate cultural level and understanding for the clinical trial.
* Signed informed consent

Exclusion Criteria:

* Subjects with BMI ≥30 or \<25 kg /m2
* Subjects diagnosed with Diabetes Mellitus.
* Subjects with dyslipidemia on pharmacological treatment
* Subjects with hypertension on pharmacological treatment
* Subjects with established diagnosis of eating disorder
* Smokers or those subjects with high alcohol consumption (\> 2-3 servings/ day in men and\> 1 serving/day in women (1 serving = 1 glass of wine or 1 bottle of beer)
* Subjects under pharmacological treatment (except oral contraceptives)
* Subjects with large weight fluctuations of more than 4 kg or who have undergone in six months a weight loss diet
* Subjects with sensory problems
* Subjects with gastrointestinal diseases that affect the digestion or absorption of nutrients
* Pregnant or breastfeeding women
