Completed

• Conditions: Overweight
• Interventions: Dietary Supplement: High Protein; Dietary Supplement: Low Protein

• Registration Number: NCT01776359
• Lead Sponsor: McMaster University

Brief Summary

A four week intervention will take place with the participants. They will undergo 6 days a week of high intensity training. They will also be at a 40% energy deficiency. One group will have a normal intake of protein, 1.2g/kg, while the other will have 2.4g/kg. It is our thesis that the participants with the higher protein will retain more lean mass.

Primary Outcome Measures

Name	Time	Method
Body Composition	4 weeks	To compare the effect of normal protein intake (1.2 g/kg per day) and increased protein intake (2.4 g/kg per day) on body composition over a 4 week period of energy restriction in young males (18-30), with intense exercise training. Body composition will be measured via DXA, Bod Pod, Bio-impedance, skin folds.

Secondary Outcome Measures

Name	Time	Method
Psychological state	4 weeks	To compare the psychological state of the participants, before, during and after the intervention. To see if the mind will grow with the body as high intensity exercise is performed, or whether the mind will tire and scores will be reduced.
