1st of November because of liver, pancrease and kidney isues I was told I had to lose a substantial amount of weight. Put me on 1450 calories per day, no fats, etc. So far I've lost about 35 lbs. Dr told me this week I could continue to lose weight or could level off, but still layoff the McDonald's burgers and fries.
In my case coffee actually helps my liver issues. Losing the weight has also resulted in significant health benefits. I've dropped off two blood pressure meds, and will taper off a third. My knees and back are better, and I'm walking more.
