SALLY-ANN CREED AN­SWERS YOUR QUES­TIONS

‘Is it true that there are ad­verse ef­fects to ke­to­sis?’

Q: Should I take omega-3, -6 and -9 fatty acids?

A: You only need to worry about omega-3 fatty acids. The source should be fish oil, not flaxseed oil. Even though omega-3 and omega-6 fatty acids are both es­sen­tial fatty acids, you prob­a­bly get way more than enough omega-6 fatty acids. Omega-9 fatty acids are found in av­o­ca­dos and olive oil. They’re good fatty acids but not es­sen­tial, as the body can cre­ate them, so there’s no need to take a sup­ple­ment.

In the food in­dus­try, vir­tu­ally one hun­dred per cent of the oils used are seed oils – and they’re very high in omega-6 fatty acids. This throws out your ra­tio, which should be 2:1 or 1:1 omega-6 fatty acids to omega-3 fatty acids. In mod­ern man it is any­where from 10:1 to 50:1. To bal­ance this, take a fish-oil sup­ple­ment or eat fatty fish three times a week. Don’t con­sume any­thing with omega-6 fatty acids in it (veg­etable and seed oils such as canola, flaxseed, hemp, sun­flower, and saf­flower, as well as soya, mar­garine, pro­cessed foods, and sup­ple­ments), as you get enough al­ready.

For­get the seed oils – they dam­age your health, con­tribut­ing to car­dio­vas­cu­lar dis­ease and in­flam­ma­tory dis­or­ders. There are so many de­li­cious fats and oils that are safe and healthy: all an­i­mal fats plus olive oil, macadamia oil, av­o­cado oil, co­conut oil and but­ter.

Q: I love fruit but it’s not usu­ally in­cluded in the LCHF lifestyle. Are there any I could eat oc­ca­sion­ally?

A: If you re­ally want some fruit, rasp­ber­ries are best, as they con­tain only 3g carbs per half cup. See the list op­po­site of some fruit you might want to in­dulge in, es­pe­cially with sum­mer com­ing. Work out your carbs ac­cord­ingly.

Q: Are there ad­verse ef­fects to ke­to­sis?

A: It’s not nec­es­sary to go into ke­to­sis to lose weight. Some peo­ple (es­pe­cially men) do very well on a ke­to­genic diet, but we’re all dif­fer­ent. For di­a­bet­ics it might work bet­ter than any­thing else, but for those with a slug­gish me­tab­o­lism it might not be that great. Seizures are well con­trolled in ke­to­sis, and it is also ben­e­fi­cial to those with Alzheimer’s dis­ease, Parkin­son’s dis­ease, autism, bipo­lar dis­or­der and poly­cys­tic ovary syn­drome.

It’s ex­tremely hard to sus­tain a ke­to­genic diet, though, so cy­cling in and out of it might be bet­ter.

In the long term there are pos­si­ble ad­verse ef­fects to con­sider. Some of the prob­lems I’ve seen in women who sus­tain ke­to­sis for too long in­clude:

• Hy­pothy­roidism • Slow­ing down of the

meta­bolic rate • Loss of pe­riod (and pos­si­bly

in­fer­til­ity due to this) • Other men­strual ir­reg­u­lar­i­ties • De­pres­sion • Sleep prob­lems • Con­sti­pa­tion/di­ar­rhoea • Vom­it­ing, nausea/re­flux • Thin­ning hair • Kid­ney stones • Mus­cle cramps • Hy­po­glycemia • Nu­tri­ent de­fi­cien­cies • Heart ar­rhyth­mias • Acute pan­cre­ati­tis

If you feel you’re dam­ag­ing your health rather than ben­e­fit­ing from ke­to­sis, stop, and fol­low a more bal­anced low-carb diet.
