What? He's 100% right. You will lose weight, it's just not in the areas you want. I've followed a similar path and have slowly but surely lost weight all over (~100lbs at this point): abdomen, chest, arms, legs, face, and neck. It really is as simple as a calorie deficit. Good nutrition mixed in with that and exercise can help to bolster results but you don't need them. The first 6 months all I did was watch calories—no exercise—and lost a good 50-60 lbs. The thing missing for most folks isn't genetics, it's patience. If you start off big, it takes a long time to "get skinny." You lose a ton of weight early on and then as your body adapts, fat loss slows but doesn't stop. That's not disingenuous.
