I can tell you clearly that it will have an effect, but the effect is passive, because eating will make you feel full. How much do you usually eat? Maybe you can eat half after the operation. However, if you can't change your habit of eating seaweed, you will gain weight back sooner or later.

My experience of losing 58 pounds is one or two pieces of whole wheat bread, an egg and a glass of milk in the morning; For lunch, a whole wheat bread sandwich (subway in simple words) without salad dressing; Eat vegetables and fruits with chicken or fish for dinner. After more than three months, I lost 60 pounds. Before that, my height was 185 and my weight was 2 15 kg. Of course, it may also be related to my personal physique.

Judging from the weight, it should be habitual to eat more, and I am afraid that many of them are oily polysaccharide foods. From the health point of view, I suggest you try it first according to my personal experience above. If you think the amount is too small, you can increase it appropriately, such as eating an egg or drinking a bottle of milk, and eating more pieces of chicken or fish. But the bottom line is, try not to eat fried food, salad dressing and Chinese dishes. It is best not to try gastrectomy. Wish you success!
