About a year-&-a-half ago, my husband decided to go on a fat-free diet. His father died of heart-related problems while in his early 60s, as well as other family members having similar health issues. He never went to see a doctor to have his health evaluated, so he took it upon himself to eat this way so he'll live longer than his father. It's not just a diet, it's become a lifestyle. Although I give him credit for taking his health into his own hands & it takes a lot of willpower to eat the way he does since his diet is extremely restrictive, I don't know if this is completely healthy. The only foods he eats are beans, vegetables, fruits, oatmeal, & a small amount of brown rice, whole-wheat pasta, whole-wheat pancakes, & a limited amount of dried fruits. He eats no butter, oil, dairy (not even the fat-free products), nuts, foods containing processed sugar, fish, lean meat, poultry, avocados, or olives. Some of these off-limit foods even contain the good fats, but he still won't touch them, even in moderation. And certain types of seafood even have no fat, but because of the cholesterol he won't eat them. The only fat he gets is from the trace amounts found in some of the foods he eats. He says he feels better & has more energy eating this way, & has naturally dropped a lot of weight, although that wasn't his intention for going on this diet since he never had a weight problem to begin with. I also notice with the way he eats that it's almost as if his whole life revolves around his way of eating & he has become somewhat of a health-food control-freak. His appearance is extremely thin & I see some changes in his personality. I don't know if this diet has brought on these personality changes or it's just a coincidence. I know that a lack of fat can cause the hair & nails to become dry & brittle, but can it have a negative effect on the brain, as well?
His diet is actually very healthy except for a few things. He might try adding in the avacado's (as over all they are extremely healthy) and some Extra Virgin Olive Oil. His heart is his concern and his diet caters very much to a healthy heart. However there are some foods eaten in moderation that will not hurt his heart and will greatly help the rest of his body. Some sea food or an avacado would be very healthy and some EVOO once in a while would provide good cholesterol that wouldnt block his heart but would help the rest of his body function properly. For proof he should look to the cultures that eat these foods regularly. Italians consume huge amounts of olive oil and they have very healthy hearts. Japanese consume large amounts of sea food and they too have healthy hearts. Also he must remember that diets are only half the battle, exercise is a must. And finally drinking lots of water is very important to maintaining a healthy lifestyle.
I hope this was helpful, basically your husband is on the right track but he might be even better off with a little good cholesterol.
