Effects of High Protein Intake With Intense Exercise and Energy Deficit (RIPPED)
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 Purpose: Basic Science
|Official Title:||Effects of High Protein Intake With Intense Exercise and Energy Deficit|
- Body Composition [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]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.
- Psychological state [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]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. Measurement tactics will in include POMS, and PANAS questionnaires for mood, and stroop, isometric hand grip, operation span test, and vigilance task.
