Is the pre-squeezed lemon juice in the bottle as good as fresh squeezed lemon juice, for losing belly fat?

None of it (lemon juice or any other juice) is going to have a huge impact on your belly fat, but eating a clean, reduced calorie diet and getting plenty of exercise, will definitely have some effect.

I’m more hesitant about drinking those lemon juices out of the bottle, because they have preservatives in them. Just get a juice press, buy lemons and squeeze your own.

Poor fool.

All juice has fructose in it and fructose MAKES the 'belly fat'.

The bottle is as bad as fresh-squeezed.

They are both about as good as wearing a tinfoil hat. There is only one way to lose weight: burn more calories than you eat. You can eat anything you want and still lose weight as long as you don't eat too many calories.

Yes, they are equivalent in their effects on belly fat - - - namely that they have NO EFFECT AT ALL.
