>>> an apple a day keeps the doctor away. but just like that expression some of the medical advice maybe a little bit outdated.

>> there's a new school of thought on everything you thought from what to eat for breakfast to exercising.

>> and dr. steven lamb is the director of men's health center at nyu. lead it away.

>> should you limit egg con sumps to protect your heart.

>> they always said yes.

>> but i think there was issues with cholesterol but it's outdated now so it's false.

>> that's right.

>> it is correct. eggs really do have cholesterol in it and you can't be eating a lot. it turns out it has a lot of nutrition and people that are really eating well, don't eat a lot of saturated fat . it's perfectly acceptable to have an egg. maybe if you have really bad diabetes, maybe not so great.

>> how many eggs a week are we talking about.

>> i always get egg whites .

>> just eat the egg.

>> will you call my wife.

>> why don't you want an egg white omelet? because it stinks.

>> no, it's not bad food. it's a bad diet. if you want an egg it's perfectly fine.

>> is there a perfect amount you shouldn't eat.

>> i wouldn't have the bacon with it and i wouldn't have the margarine with it and french fries with it but if you wanted to have an egg perfectly fine.

>> is it possible to catch up on lost sleep? true or false.

>> false.

>> you guys all know that.

>> we try every day.

>> this is both true and false. depending on your genetic make up. there are what we call owls and larks. they respond differently to social jet lag . people who are sleep deprived and try to make it up on the weekend. here's the problem, we have a clock within the brain. if you try to get up during the week at 7:00 and on the weekends 12:00 or 1:00, you're throwing off your clock and setting yourself up for disaster on sunday night. so you can bank a little bit of sleep, but you have to be really careful not to go, let's say you're waking up at 7:00 and then waking up at noon, maybe wake up at 9:00 or 10:00 .

>> we don't have that problem with little kids. 6:00 a.m ., what.

>> switching gears, when it comes to losing weight interval training is the most efficient way.

>> true.

>> it can be as little as 7 seconds or 30 seconds or 45 seconds where rest periods are a minute or two minutes. it's a fantastic way of becoming efficient. there's even this four minute workout. not great for weight loss but you can improve your fitness level but 20 minutes is much better than 40 minutes of regular training.

>> research shows you can burn three times as much fat in half the time. it's really effective.

>> the 45 minute session on the treadmill is not doing it.

>> you're wasting your time.

>> how dare you say that. that's what i have been doing.

>> i'm going to eat nothing but regular eggs in my omelet.

>> and jump rope.

>> really.

>> switching gears, if your nasal mucus is hello or greenish you have an infection and need an antibiotic.

>> true, that's what they always said. anything green coming out of you needs antibiotics.

>> it's first false but then maybe true. okay, the reason is, the color of mucus doesn't mean it's a bacterial infection . it maybe inflammation or a virus. however it was green and then becomes green or yellow with fever then you do need it.

>> one more using peroxide or rubbing alcohol are the best way to clean a scrape.

>> true. i would say true. you have to clean that sucker out.

>> false.

>> how are you still alive.

>> it's a little bit of overkill.

>> you really can just get away with soap and water. a little bit of antibiotic and a band campers.

>> the peroxide can injury the surrounding healthy tissue. doesn't mean you wouldn't use it on inanimate objects but if you have running water and mild soap, you're better off and cover the wound is a good idea.

>> i need your card. that's what we have learned.

>> you need to move in with dr. lamb.

>> thank you both very much.
