Protein is not "just the meat". You do NOT eat 50% of your diet in meat! Every food you eat will have *some* protein in it.
I cannot comment on the safety or efficacy of the plan itself (although it goes against current expert knowledge in this area and pretty much everything on Dr Oz is a scam...), but as for the actual values ...
Say you have a 1500 calorie diet.
You would want around 750 calories from protein, or 187g.
You'd want around 450 calories from fats, or 50g.
You'd want around 300 calories from carbs, or about 75g.
Plus or minus 20% for a range, eg protein 150-224 g per day.
Then start tracking and see how the numbers add up.
Remember to include as much plant based protein as you can (beans and legumes) as they carry much less fat than animal protein and at those values you'd have difficulty getting enough protein and keeping the fat that low.
