Outcome Measures

Primary Outcomes (1)

  • weight reduction

    Compare the effect on weight reduction of intermittent energy restriction and a isocaloric continuous energy restriction in obese subjects

    1 year

Secondary Outcomes (7)

  • cholesterol

    1 year

  • adverse events

Study Arms (2)

intermittent energy restriction

EXPERIMENTAL

dietary intervention, intermittent energy restriction. Participants in the experimental group will follow av 5:2 diet and consume a very low calorie diet providing 400 (females) to 600 (males) calories of energy to days a week and for an average male participant, this will reduce energy intake approximately 22%.

Other: dietary intervention intermittent energy restriction

continuous energy restriction

ACTIVE COMPARATOR

dietary intervention, continuous energy restrictions.Participants in the active comparator group will be asked to reduce daily energy intake by 22-23%

Other: continuous energy restriction

Interventions

Randomized clinical trial

intermittent energy restriction
continuous energy restriction
