My mum was told the same thing when her weight loss stalled. She mentioned to the consultant that she ate a lot of fruit and was asked "do you eat it because you're hungry or because you like it?" The answer was becuase she liked it so she cut it down slightly and got to target.
The thing is we wouldnt eat chocolate/crisps/biscuits "because we liked them" and expect the weight to fall off. Just because fruit is "good for you" we think we can shovel it down willy nilly
Don't forget that fruit has been modified over the years to contain more sugar!
Has it? Never heard of this before. What's it about?
