Other: Sour cream
Sour cream with jam and three slices of bread
Experimental: Obese
Overweight and obese subjects (BMI≥25) with a waist circumference of ≥94 cm for men and ≥80 cm for women. Subjects will be randomly assigned to eat butter, cheese, whipped cream and sour cream in a cross-over design.
 Other: Butter
Butter with jam and three slices of bread

Primary Outcome Measures :
  1. Changes in levels of circulating triglycerides [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]

Secondary Outcome Measures :
  1. Changes in total cholesterol and lipoproteins [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
    Changes in total cholesterol and lipoproteins, such as low-density lipoprotein and high-density lipoprotein

  2. Changes in levels of apolipoproteins [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
    Changes in levels of apolipoproteins, i.e. apo A1, apo B, apo B-48 and apo C-III

  3. Changes in levels of free fatty acids [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
  4. Changes in levels of circulating inflammatory markers [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
    Changes in levels of inflammatory markers, such as cytokines, acute phase proteins and soluble adhesion molecules

  5. Changes in levels of circulating endotoxins [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
  6. Changes in gene expressions (mRNA and microRNA) of genes related to lipid metabolism and inflammation in Peripheral Blood Mononuclear Cells (PBMC) [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
  7. Changes in whole genome transcriptomics in PBMC [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
  8. Check DNA for Single Nucleotide Polymorphisms related to responses of a high-fat meal [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
  9. Examine epigenetics through DNA methylation and histone modification [ Time Frame: Measured at baseline and 6 hours after intake of test meal ]
  10. Changes of plasma and urine metabolomics [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
    Changes in levels of metabolites, such as glucose and amino acids

  11. Changes in levels of gut hormones [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
    Changes in levels of gut hormones, such as peptide YY (PYY)

  12. Changes in experiences of hunger and satiety by Visual Analogue Scales (VAS) questionnaire [ Time Frame: Measured at baseline and 2,4 and 6 hours after intake of test meal ]
