I too am struggling with having gained weight and not being able to exercise. Since i have never been a big vege lover, and i have been trying to eat healthier foods, I have started drinking green smoothies (spinach, romaine lettuce, apples, bananas, berries, cabbage, a bit pf ginger, some truvia or honey) before each meal. i do think doiong so is helpful for me So long as i dont eat junk (salty carbs, sweets) in between meals due to being stressed (and seems like the only thing that i can do without getting tired is eat).

I use a blendtec blender and although pricey i have tried less expensive (including ninja one that claims it is as good as blendtec) but they are not the same.
