Keeping a calorie deficit doesn't mean starving yourself. You need 3000 calories a day? Eat 2000, you'll lose about 1 kg in a week. At least it works for me and lots of other people I know. Sure it's hard to keep 2000 when you usually eat 3000-5000, but health is worth it. If your overweight is life-threatening you'll want to lose body-fat asap, which you will not achieve if you first try to understand every detail of digestion and nutrition. See it as kind of first-aid. I know that losing weight is very hard and that the behavioral change is the key, not the unknown details of nutrition. I just wish people (especially my doctors and family) pushed me much earlier to the right behavior.
