>> building a better bay area, moving forward, finding solutions, this is abc 7 news. >> i'm kristen sze you're watching getting answers on abc seven. everyday we talk about issues important to the bay area and we get answers. we have new secrets about dropping pounds and keeping them off. stanford researchers have this coupled -- discovered two biological -- one of the authors will be joining us. have you heard of kenzie mcdonald? making headlines with the shocking upset victory taking down rafa. we will talking -- will be

talking with a high school tennis coach. microsoft announced it is cutting 10,000 employees while amazon started trimming another 8000 jobs after shedding 10,000 positions last month. joining us to discuss the latest contraction in the tech industry and what it means for the bay area, and what it means -- is a tech reporter. >> thank you for having me. >> are some of these and amazon jobs located in the bay area that are being cut? >> definitely, some of the workers in the bay area, depending on the company, a bulk of them are in washington state. i do not think we will see that much impact in the bay area. >> that is where those companies are headquarters. what the moves shall -- s

>> i saw some call it the great reset that is pretty accurate. during the pandemic there such a boom for these companies they were hungry to hire great talent. now as we ease into a they are cutting aggressively weekly before the burn exceeds what they can handle it is a great reset as i've seen. >> during the pandemic there was a lot of hiring and growth, is there as -- an expectation that they will make my this year or they expect to be slow for quite a while? >> profitability depends on the company, the co said they're looking at a tough two years. a lot of tech companies will be making aggressive cuts for the next year or so. it will still be difficult

moving forward. >> for viewers not following all of these cuts can you tell us about some of the bay area companies and how many they have cut? >> yes, when the biggest ones we covered at fortune was a salesforce layoffs. thousands of workers last month. one of the cuts they are making was to the real estate footprint across the world. obviously salesforce has a great, very large footprint in sf bay area. that is one of the most impact -- impactful cuts you see in the bay region. >> metta, san twitter, netflix, all them in the bay area. how many jobs total in the past six months or so have been cut? >> hundreds of thousands. there is a nifty website

layoffs.fyi we can see the layoffs in a spreadsheet. hundreds of thousands and there will be more. >> are there other sectors and other people in other jobs who are not intact also affected? >> yes, there are a lot of people in tech companies that do not work just in tech. salesforce sells software to other companies. it is a cascading effect. these tech companies are having on many industries. reporter: even outside of the industry the workers and going into the office. they are not buying lunch. the mom-and-pop bakery is not getting the business. the city is losing attack space. is any -- losing its tax is any tech company immune? >> no. salesforce owns a slack and the slack co says you see this at the highest levels. no one is immune.

>> i am trying to look for a silver lining. if there are a lot of engineers and other roles or people are out of work, are there employers who are hiring? is anyone benefiting from this? i am thinking government that could not compete with the big companies last year, but maybe now they can. >> you hit the nail in the head -- on the head, is there a silver lining? a lot of people be hungry for the top tech talent and these people land on their feet. there are government roles come up with cannot get the talents before now have access to that talent. >> not only are the payrolls down, i think the stocks, for a lot of these companies are down as well. if they are fundamentally sound companies, the question is, is this a good time to invest and buy stocks at a discount? >> i cannot really speak to that, but if you see an opportunity right now, maybe it is the best time to go for it.

>> the crystal ball, when well hiring pick up again? >> that depends on the industry, company, i think the next year, as microsoft said, if they say the next two years will be tough, you should believe they will be tough. 2024 should look brighter in terms of higher. >> the cuts keep coming, tech reporter for fortune magazine, thank you very much. here is a question on a lot of minds. do you want to know how to best to lose wait and keep it up for you? stanford researchers say they have made interesting new discoveries on how to do that. it is based on biomarkers.

(vo) wells fargo lets you know where you stand with your fico credit score. what if you knew where you stood with everything? like your future in-laws... (boyfriend) hope you like cats...

(hero inner thought) i hope your parents like me... they're whispering. (father in-law) the kitties like her... (hero inner thought) can they tell i'm allergic? (mother in-law) tears of joy... (father in-law) welcome to the family! (hero inner thought) whew! (vo) like knowing where you stand? when it comes to your credit score, you can with wells fargo.

kristen: if you have had a hard time losing wait and wondering is it me? is my behavior? my genetics? stanford researchers have a new answer -- have an answer from a new study about biomarkers where they can predict an individual's ability to lose wait. joining us, is professor and chair -- co-senior author study, dr. snyder. welcome to the snow -- show. everyone wants to talk about weight-loss, especially in january, new year's resolutions, what question did you set how to answer? >> we are all different we all respond differently to different foods.

we metabolize foods differently. nobody is the same. somehow diets seem to work on some people and not others. when we took a crack at this we put people on two kinds of diets. one is low-fat and one is low carbs. both are healthy diets, one is reduced in carbs and the other in fat. turns out if you adhere to your diet you lose wait weekly on either diet. to keep the wait off in the long-term term it depends on what your starting point was. depends on who you are. people with high metabolism do better on a low-carb diet to keep losing wait and keep it off. others, some of the other diets, not so much. there are very specific proteins that work correlated with this. associated with this weight-loss. if you have a certain starting point you are more likely to lose wait and keep it off then if you are in a flavor if you are. a different type of person.

it has to do with your metabolic enzymes. some enzymes metabolize fat or carbs differ in and the levels are different in different people. kristen: i think you said high metabolism does better with low-carb, right? how do you know which is you? i imagine in your study you found some way to tell people, each person what you are, looking at your biomarker. how do we know that? >> task, this thing -- test, this things we discovered. it is called a. respiratory quotient. you can go get it. kristen: how does that work? >> you measure your carbon dioxide to oxygen ratio. it is an energy consumption. there is a device for doing that. it is a very simple device. we also have biochemical markers. you know how you go to the

doctor and they get a blood test, they measure a few proteins in a few metabolites. we have discovered some that are also associated with it. in the long run it may be an easier marker for telling which kind of person you are in was kind of diet is best for you to lose wait. kristen: i see. >> you can struggle a lot to lose wait and think it is all you, but is probably a bit inherent to your metabolism and protein structure, if you will. kristen: i am so happy to hear this. i always think it is a failing on my part if i cannot keep the weight-loss. you can start out, lose some wait, whether or not you can keep it off successfully, you do need the right diet for your -- i just want to say metabolism type, is that the way to look at that? >> that is exactly right. your enzyme -- wh competition -- composition looks

like is if you can keep it off in the long run. you still have to adhere to your diet. >> as in a number of calories? calories are still calories, right? >> that is correct. kristen: what are people who want to gain wait? my colleague spencer, all life, had a hard time eating as much as he can come if he is so trim. is there implications are people that want to gain wait? -- weight? >> we have not taken that on yet, but i have the same problem. i have to eat constantly to not lose wait. we had not stated that, with the big tape from personal experience, lifting weights and building muscle mass is one of the best ways to gain rate -- weight. >> he does that. has your findings dispelled any myths? >> the one myth you could argue

we dispelled, we assumed like you said it is all the person. they are not adhering properly. they are doing something wrong. certainly have to adhere to the diet, but you will get a better response depending on what your actual composition is, if you will come your protein composition also these microbes, it is called your microbiologist the factor as well that will determine your ability to lose wait on a different kind of diet -- weight on differ kinds of diets. is a new frontier on how people respond to different foods. we should be taking it on a much vigor way, at the end of the day everyone will respond to diets differently. kristen: now that you have discovered this, it is not like there is currently a test for your gut microbes strains or what you have. where do we go from here? so you can build on the

discovery and help people very practically? >> one is exactly what you just said, figure out, let's get these tests set up, obviously we want to validate although it is a reasonably large study we are confident it will validate, then we should turn this into test so people can optimize their diet with the right tests. some of the markers we saw are important to bolick barker's -- metabolic markers. important inflammatory markers as well. bringing all of these into your health and getting a bigger picture is a starting point so you can better manage her lifestyle. i think this is the future, you'll be shopping with the screen shows for different foods that will best work for you. kristen: dr. michael schneider, very interesting, thank you for coming on today to share your findings with us. >> thank you for having me. kristen: did you see this yesterday? a moment in sports last night

kristen: now to the story of an underdog's greatest professional achievement to date. a 27-year-old tennis player from the bay area ousted defending champion rafael nadal from the australian open. people were simply stunned. joining us live now is mcdonald's or merck tennis coach at piedmont -- former tennis coach at piedmont high school. thank you very much for joining us today. >> thank you for having me. >> how are you feeling? >> it was awesome to watch it. you are always on pins and needles, especially when you are playing one of the greatest players of all time.

especially after the first set you always get nervous. can they win the second set? can they win the match? he has a lot of fans in piedmont, i can tell you that. we were all communicating with each other. i do not think i have ever seen him play as well as he did last night. i have known him since he was seven years old. kristen: tell us about that. the little tennis player that he was, when you first met him and took him on, and the kind of human he has been sent. -- sense. >> he would come to some of the clinics the pros withhold, teaching tennis, he was always involved as one of the participants. even at seven and eight years old, he had an unbelievable amount of presence. we were just hoping that, when he got to high school that he

would play for piedmont. it is very unusual to have world-class player like mackey number one of the nation in the 14th and 16th to play high school tennis. most juniors do online school online -- ended up play, it was a pleasure being his high school coach. i want to be clear, having him as a high school player was not the same as what his teaching pros. how they brought him along, like rosie or wayne. we worked a lot on strategy and the matches that he played. his freshman year he played, i would say nine or 10 matches.

really the only matches we only needed him at number one. we had some really amazing players. in his freshman year we only played -- he only played one match because he had his serious illness and he was out from school for quite a while. he came back and played the finals of the team championships. even though he was literally, like, did you percent at best he really wanted to play -- 50% at best and he really want to play. i do not think our school has forgotten that. that he made the command to play for us. we are so proud of what he is done on the tour. kristen: i can see it in your face and curate on your voice. for a top level player at high school and be committed to his teammates, classmates, school, and play for fun it is unusual.

it'll most becomes a job that says a lot about what he is. for folks that did not know he was unseeded and he never move past a fourth round the major. i was wondering if yesterday was a surprise, or if you thought his time had come. were you surprised? >> i am never surprised by him. when he was in the juniors he was not a very big guy. he was number one in the 14s. when he gets into the 16s he will not be that tall because his parents are not that tall. then number one in the there is number one and number two at the time, same thing the kids are growing taller, big serfs, there he was winning again. he was one guy you can never

count out. one of the things, his last injury that was pretty traumatic. she tore his hamstring at the french open -- he tore his hamstring at the french open. that stalled him a little bit. he made the finals of the d.c. tournament. before his hamstring he made the round of 16 at wimbledon. it was a phenomenal run. we have always had a lot of pride. he can do it all. you can play singles, doubles, he has all the shots. i think, at some point we were hoping, i know he has been playing well at the end of that he would continue into 2023 and looks like he has. kristen: look into your crystal ball, what are his chances in the word round on friday -- third round on friday?

is there a viewing party at piedmont? there should be. >> of course we are nervous. it is like being a family member and watching someone like him play. no matter what, even if he is cruising you are always nervous. you want to see him on the court. he is a great sportsmen. you never see him yell. he does not throw you -- rackets. i know he is one sportsmanship awards all throughout his juniors because he is a real gentleman. that has a lot to do with his parents, his family. like i said, in piedmont, there are a lot of fans, that said are you watching me match tonight? of course. kristen: i do not know what used to coach him with, if you have a little word of wisdom and he plays a match. if he is watching or listening what would you like to say to mckenzie right now? >> go for it, and come anymore

and volley. kristen: did you hear that? >> i would like to see him at the net. kristen: thank you so much, talking about the pride of piedmont today, mackenzie mcdonald, we are wishing him the best. >> thank you so much. kristen: a reminder can get our live newscast, breaking newscasts and more with the abc 7 streaming up, vale von apple tv, google tv, fire tv, roku. speaking of weather, do not go away when we come back spencer christian has

but now it is cloudy again. the rain will be here in a few hours. how many hours? we check in with spencer. >> looking at live doppler 7 you can see there is moisture in the atmosphere about the north bay. where the storm is originating. nothing hitting the ground yet. on the abc 7 exclusive strong impact scale this is a level 1 storm. this evening between 5 p.m. and 8 p.m. we will see this cold front come through. light rain with isolated heavy downpours. the timeline indicates will not move in through the golden gate city until 9 p.m.. it will move quickly and we have rapid clearing after that. we start tomorrow with more sunshine and a whole bunch of sunny days to follow. not a lot of rain with this. we do not have high concern with the storm adding to impacts like mugging or flooding. just pooling and ponding on the road.
