Maybe some of the weight is water retention and you may need to take a diaretic? I did when I was first diagnosed in 2012 but slowly weaned off of it.

I am having the same problem, eating no more than 1400 calories a day and during this pandemic I gained 8 pounds. How could that be? Well during my checkup with my doctor he asked me what I was eating and found out it was way too many carbs. He recommended not eating more than 60 carbs a day. So far I've lost 3 pounds in 3 weeks so maybe this information may help. I do hope so. It's a struggle when you have heart disease and just can't do the physical things you used to do. Good luck and don't give up!

Avoid processed foods. Limit portions.

I got a South Beech Diet book from the library and got some low carb recipes out of it. I bet if you googled "low carb recipes" you may just get some tasty dishes to try. Good Luck!

R u on diuretics like furosemide, aldactone,and metolazone (a booster 4 water pills)?? Fluid gain is common with ChHF. Keeping salt intake 2 1,500-2,000 / day helps tremendously. Throw out canned stuff and no tv dinners, use Swiss cheese instead of others. Knox has delicious sodium free chicken bouillon tht I use at times 2 make gravy. Restricting fluid 2 64 oz/day helps. God bless. Having CHF is vry difficult, if u ask me. I hv stage 3 diastolic HF.
