Recent health problems, now resolved, have left me about 25 pounds under weight. I found one book on Amazon, Eat Up!: The Healthy Weight Gain Cookbook, but it is not availble there or any of the several used book store websites I've checked.
Looking to vary my, olive oil on everything,whey protein in everything, avocado and pistachio nut sandwiches and Ben and Jerry's diet. I know smoothies are one answer but I find them so filling that it is hard to eat the next meal. Part of the problem is my vegitarianism but I've been eating some not farmed fish, some Murray's Chicken and might try some grass fed beef but then these meats are lower in fat too so......
