I agree, those words are better. I think you need to choose the approach you take depending on the person.
Some people that comment like my clients get “yes, I’ve been losing weight, just by eating healthy”. This is not a situation where it’s appropriate to go any further, they are there to get their hearing tested and are generally in their 70’s and 80’s
Others are obviously more curious like friends and work colleagues. They will get a more in depth version, but usually by their respsonses you can tell they aren’t ready to go into a debate about science. These people usually will get something like ‘if you would like to know more I can email you some info’ or I direct them to diet dr and the podcasts.
1 guy from work went keto from my encouragement and he has now met his goal weight and we have supported each other over the last few months. He already knew a bit about keto and was ready to take action.
So I definitely think your words and approach depends on the person asking.
