Is it ONLY About the Calories?

I found if I had more protein and less carbs, this has assisted me in weight loss.

Calorie intake dictates weight, not health. You can be skinny and unhealthy. Typically if you embark on this journey, the goal is to lose weight and improve overall health. However, some people only care about the scale. The choice is yours. If you are going to go through the effort to lose weight you might as well eat better and improve health at the same time. You'll likely feel better, sleep better and have more energy.

I would say I am not eating much different bar no snacks and fizzy drinks yet I still save 1500-2000 per day. I am full, I eat ALOT yet it doesnt seem healthy, will I continue to lose weight even when Im eating these foods that are not so good?

What are your weight loss goals? ......."I want the number on the scale to be XX".........or "I want a lower body fat % than I have now, because that's healthy."

Yes - you could lose weight on an all twinkie diet......you would lose fat+muscle because your protein level would be far too low. A twinkie diet is also low fiber.... this is not good for your digestive system (fiber is also filling). A twinkie diet is high in sugar....this is a carb....carbs are fine if you're not diebetic....but sugar is not filling.

If you save 1500 calories per day.......there is no way you are getting enough nutrition.......that's a 3 pound weight loss EVERY WEEK. "Saving" 1500 calories per day is a great way to lose muscle mass.

Pounds per week
75+ lbs to lose 2 lb range
Between 40 - 75 lbs to lose 1.5 lb range
Between 25-40 lbs to lose 1 lb range
Between 15-25 lbs to lose 1 -.50 lb range
Less than 15 lbs to lose 0.5 lbs range

Calories are all that matter for weight loss. Food choices, macros, vitamins, etc. can all contribute to health, muscle retention, fullness and satiation, energy levels, and so on, but they shouldn't affect your weight loss.
