MANILA -- As various types of fad diets and fitness programs become a trend, a health expert on Thursday reminded the public on Thursday to consult a doctor first before trying these diets.
In an interview with the Philippine News Agency (PNA), Philippine Heart Association (PHA) president Nanette Rey said fad diets and fitness regimens can affect the condition of the heart if done without proper medical advice.
"Like the ketogenic diet, it's a high-fat diet, and it does not discriminate on what fat you're taking, you could be taking the good fats and the bad fats. If you're taking it for three months, your cholesterol will go up, and if you're taking a lot of bad fats, it will deposit in the veins and they will block the veins," she said.
Citing intermittent fasting as another method of losing weight, Rey said it is not advisable for those who are diabetic and are taking medications.
"It will require you to fast for 16 hours which is too long for a diabetic patient. When a person goes under a diet or fitness regimen, it's always best to consult a doctor first. Find out what your risks are, which diet or fitness regimen would be best for you," she said.
In choosing a diet, Rey stressed the importance of sustainability and eating in moderation.
"In the long run, it is very seldom that you could sustain a fad diet, you can do that for two, four months or so but you can't sustain it for a long time. Each kind of diet has advantages and disadvantages, but generally taking more vegetables and fewer fats, that is much better than fad diets," she said.
Rey added avoiding sweets and fatty and salty foods remain the best way to achieve a healthy weight and heart. (PNA)
