I've been getting a little confused with comparing fats vs. protein vs calorie intake. Some say weight gain is purely caused by a surplus of calories. While I agree partially, I also feel like it depends on where those calories come from.
Do foods that are high in fat cause weight gain because they are high in fat, or just because they tend to also be high in calories? I know that 1 gram of fat has 9 calories vs 1 gram of protein/carbs has 4.
Let's say someone at a 2000 calorie diet of pure protein and another person ate pure fat. They're both the same calories, but wouldn't the protein one lead to more muscle and a leaner body? And wouldn't the fat diet lead to a higher body fat % ?
And lastly, many people are saying how a diet high in carbs is what is really causing obesity, etc. Because too many carbs ends up being converted to fat. I agree, but shouldn't fats still be kept somewhat low (besides healthy fats) since fat is already fat? So it's basically the same as a carb that's been converted already.
Does fat make you fat or is it purely calorie surplus that does?
Can a diet high in protein lead to fat gain just as much as an identical calorie diet of fats/carbs? It seems like that's what the "calorie surplus people" are saying but it seems hard for me to fully agree...
Thanks for any input
