Remember weight loss is all about physics and calories not total weight of the food (that will pass, as it were >.>), a calorie on the other hand regardless of source will be handled by your body the same way every time… it will either be burned or stored. your broccoli will be much better for your diet as it’s dramatically lower in calories. Steaming it, which you probably know but jic, is even better because you avoid the calories from the fat you would normally use to cook with.
Here’s a suggestion for you, rather than sitting down and eating a ton of food at one meal snack throughout the day—now I warn you, this can be very dangerous as those snack portions have a tendency to increase over time so be ever vigilant, but it will help keep you more full throughout the day and when you’re ready for a proper meal it will help you decrease the size of said meal.
Also, keep things balanced, especially if you exercise. protein and carbs, protein and carbs. not only will it be better for you, but it will also help you maintain a feeling of fullness. Switching from white flour based pastas and breads to whole grains will help with that full feeling too but remember to keep the portions small at all times, regardless of type they all have a lot of calories (and that’s your main concern). I’ve also found a full glass of water before the meal, and staying properly hydrated throughout the day keeps me eating less, yes it can add “water weight” but that can be “blasted” off where as caloric weight needs to be burnt.
So remember count the calories not the weight!
