Honestly I think SUGAR is the enemy.
I had gastric sleeve surgery last July and went from 439 pounds to now 276. The one thing I can point to is cutting sugar out of my diet almost completely. I try to make sure anything I have has less than 5g of sugar per serving. I drink Celsius energy drinks.. no sugar and some non carbonated flavors that are really good.
Carbonation expands your stomach and allows you to fit more food. So I haven't had a carbonated beverage in over a year. Not even sparkling water.
Monster Rehab is decent. 4g of sugar, non carbonated... has a tea flavor and some fruit ones too.
If you cut out sugar you are saving yourself a lot of calories too. One 16 ounce bottle of soda/iced tea is going to have 35-50g of sugar. That's INSANE.
I admit that I am a soda junkie. It's my only vice. I don't drink beer or other alcohol (never, not even on occasion, not a sip. Never enjoyed drinking, won't let it pass through my lips), I don't smoke weed or anything else. I'm a soda guy. And a FOOD guy. So yeah, that's my drug I would say. Food.
I won't drink soda with calories in it though, just because I know what I need to maintain my weight and I'd much rather eat 500 calories than drink 3 sodas with 500 calories. If someone makes it a priority to maintain their weight, but still enjoy indulging in things, I can't see how they'd be more satisfied with drinking the calories instead of eating them. If I drank three coke's (what are they? Like 140-160 a can?) and then ate 1600 calories, well I still would have had close to 2100 calories and I'd probably still be hungry because my body don't feel like it consumed those 500 calories out of my 3 cans of soda. So I just drink Coke Zero (or diet Dr Pepper) instead.
I used to really have a thing for candy like sour patch kids and gummy worms and stuff like that, but I found if I eat 800 calories worth of that stuff, it just doesn't really feel like I ate anything at all out of it. So I'd rather eat a chocolate bar (or two) with those 400-800 calories as they're more filling and satisfying.
Since we've talked about coffee, my ex girlfriend used to get a large frozen caramel coffee every morning at Dunkin Donuts (32 ounces) and she would get me one on days I went to the doctor with her, so I started drinking a lot of those and they tasted good, but they had 800 calories. I could not understand how they had 800 calories, other than being 32 ounces of fluid, but I stopped drinking them after too long because I could eat a nice steak and get that number of calories and I GUARANTEE I'd feel much more FULL and satisfied!
