Yeah he's good for science-based stuff. He's also a natural (as opposed to juiced) which is nice. Not that there's anything wrong with juicing but it's nice that his content isn't biased by juicing experience.

@DeeThree - even if you are going for 200g of protein it can be a bit difficult if you don't want to just pound chicken breasts and protein powder all day. So here's some ideas for protein + weight loss.
Lean meats obviously, but in addition to chicken breast - lean ground turkey, lean fish, and my favorite is lean cuts of beef. The beef will still run you more calories than chicken breast, and yes it's not as juicy/tender/flavorful as strip or ribeye etc, but it's still steak and it's actually a lot cheaper than tastier cuts. I do top round steaks probably twice a week, only like 6 bucks a pound at Aldi. Top with steak sauce, worchestershire sauce or horseradish sour cream sauce, onions and mushrooms, etc.
Protein powder obviously, isolate if you can afford it, not a huge difference but saves calories. I usually use the pow to fill gaps between meals since it's best to space out protein intake. Late night treat is sugar free nut milk, sugar free puffed wheat cereal (50cals/cup), and protein powder. There's also protein powder microwave brownies/cakes.
Nonfat Greek yogurt. I enjoy it a number of ways... Overnight oats with berries... But one great way is making ranch dip for veggies. Just add powdered ranch packet to yogurt and enjoy a really tasty, macro-friendly, healthy snack.
Lastly... Most underrated imo... Fat free shredded cheese. It's pure protein. Definitely not as good as regular cheese but it's about 1/3 the calories.
And of course obligatory "fat is not bad for you, you need fat" - but low fat or fat free foods allow you to control your calories and macros a lot more easily.
