GRAIN FREE DIET – HEALTHY FOR A FAT GUY?

my bf is flattering complicated similar to 270 as well as 5′10. he not long ago motionless to go upon the low- carb, grain-free diet formed upon the little internet articles he read. instead of eating full of health things which you routinely eat similar to veggies as well as beans as well as total wheat pasta, he is replacing it all with eggs as well as beef as well as butter as well as salad with blue cheese dressing. i do not assimilate how this can presumably be healthy. i’ve attempted to discuss it him he should only go on to eat the same full of health dishes you were eating, only in not as big portions as well as no seconds. though he’s assured this diet is full of health for him. i’m disturbed since his father died of the heart conflict during the immature age, as well as he’s never had his cholesterol checked. how can i remonstrate him this is bad for him? or am i wrong? he’s 32 years old.
