My husband passed away and the next 6 years I ate my grief away. I had a heart attack recently because of it, before that I had my diet pretty well under control. There are certain nutrients we need especially with a damaged heart and certain supplements that we can't take or that's not good for an unhealthy heart. My advice is to definitely ask your cardiologist about talking to a dietitian or nutrition specialist, otherwise you will have to do the research yourself online. My heart attack was most severe and I was put on a six to eight carbohydrates, per day, sugar free diet. I lost 40 lb in 4 months and I'm still losing but more slowly now. We need to understand that weight loss takes time and effort it can be very difficult for some of us. Weight also comes off fast in the beginning and then slows to a crawl which can be discouraging. God bless you with your health and success in dieting.
