Is a zero sugar diet healthy?

you don't actually need sugar at all. I assume they're eating other carbohydrates? If they are, then it's not even out of the ordinary, just more restrictive. I don't think it's any better or worse than anything else. I wouldn't do it as it would be hard to find enough food to meet the 3000 some odd calories I need every day in order to maintain, but it's not inherently any worse than a normal diet.

I seen that too, but really I like my fruit could not go with out it.

Remember we need to think lifetime, not gameshow ( and losing 4kg to keep immunity lol )

I think it is IMPOSSIBLE to go 100% sugar free...natural sugar is found in so many things,,,, you can go maybe 95-98% sugar free but from my understanding, the body needs some amount( unknown to me) of sugar ( natural)

I don't think it's impossible on a low or ketogenic diet. But I wouldn't do it. I don't see any reason to do it, it doesn't help you lose weight any faster, and if you don't plan on that type of diet for life, you'll just have to learn how to eat again after you go off of it.

I blogged about low carb here:

feel free to read up on it, it's an overview of how the body handles carbohydrates and what a low carb diet entails.

Personally I can see a life without any "added" sugar, but no sugar at all when its naturally in fruits and veggies. Smh, I don't think its possible. I also agree we should be thinking way of life, not a temporary solution. All the best.

I may be wrong but I don't think the trainer would use that as the long term diet? I think it was just because Meg needs to drop her weight gain this week and I think you do lose more weight by cutting out sugar completely.
I could definitely not cut out fruit and things for more than a few days...

Cutting all sugar IS possible!! The ketogenic diets I've looked at are used quite successfully to treat epilepsy and to heal cancer!! Don't label me a looney on this one until you've read the research. Sugar IS the devil, folks, no doubt about it. The ketogenic diet is not a zero carb diet, but the carbs you consume are all from veggies, like greens, tomatoes, red peppers, raw onions, green beans, etc. The ratio of fat to protein is 1:1, much like paleo or primal diets.

Not arguing that fruit is bad in general, but for some who are insulin resistant, it can stall fat loss.

I am ketogenic and have my carbs very, very low. No it is NOT possible to have zero sugar IF one is eating vegetables. Green leafy vegetables likely only have a trace, but it's there nonetheless. Other veggies have even more sugar. However, is eating a teaspoon or so per day of natural sugar in vegetables likely to be problematic? Not.

Can one live without sugar completely? Yes, the Inuit did. But they did eat berries for a short time every year.

I don't find it very hard to eat a very low carb diet and it's permanent for me. It's not hard because I love not feeling sick and hungry and I've always preferred an animal based diet.

Tomatoes and red peppers both have sugars.
