Hi Daniela - thanks so much for your kind comments!
Make sure he's eating small but frequent snacks/meals, and using his soluble fiber foods as a safe foundation to add in small amounts of IBS safe proteins (seafood, skinless white meat poultry, egg whites, finely ground nuts, pureed beans/lentils) and small amounts of heart healthy fats (olive, flax, avocado, etc.). Both the proteins and fats are important for energy and satiety, but use them as additions to the foundation of soluble fiber foods so his gut stays calm.
If he's eliminated coffee but needs the caffeine he can use black or green teas.
He may also just need some extra rest and sleep. IBS can be really draining and exhausting, physically and mentally. It is a wonderful sign that he's feeling better, and as that continues he should see his energy pick up as well.
If he can add in some gentle (not extreme, like sprinting) exercise that will help him increase his energy levels as well, and also likely help IBS. Yoga is the perfect fit for both of these.
Please keep me posted, and give him a hug for me. And you too - caretakers need taking care of, as well.
