Facts about fat (the macro-nutrient), fat (the stuff piling up on your waistline), and carbs…
.
– Fat is a structurally integral part of every single cell membrane in our bodies.
– Fats are required in order to properly digest and assimilate those all-important fat-soluble vitamins: A, D, E and K. Conveniently, many foods containing these vitamins also come with the fat required to digest them. For example, the fat in egg yolks allows the body to access the vitamins A and D it’s so abundant in.
– Fats are required for the adequate use of protein.
– Fats are a source of energy, and a nice consistent, smooth burning energy at that. They also slow food absorption, which helps with energy regulation as well.
– Fats are key players in managing inflammation in your body. Some fats help your body inflame when necessary, other fats help your body anti-inflame.
When you eat something sweet, your blood sugar levels increase too quickly, and your pancreas secretes the hormone insulin to take the excess sugar out of your blood. Insulin is a fat storage hormone. It stores that extra sugar first as glycogen, and then as triglycerides (fat) once glycogen stores are full.
Sugar mobilizes insulin; fat does not. In fact, the fat in a sweet treat will actually help to slow down that sugar spike, and thus reduce the insulin surge, mitigating some of the ill-effects of the sweet. This is why the whole fat-free dessert thing is such a bad idea. Not only are you mobilizing a ton of insulin, you’re also removing the one thing in there that could slow that process down.
The digestion of fats triggers your satiation mechanism. This is why low-fat diets are doomed to fail and such an exercise in fierce willpower. Your body is never satisfied without fat, despite the number of calories (one more reason why calories aren’t the be all and end all).
This means: eating fat makes you fuller sooner and longer. Eating sugar leads to a sugar crash which makes you hungrier sooner and in a position to crave more sugar. A vicious cycle indeed.
And, of course, sugar is a carb. This is why high fat/low carb diets lead to weight loss. Fats are good, as long as they’re good fats. Saturated and trans fats – not so good. Unsaturated fat – very good. Low fat foods are typically high in carbs. Eating low fat AND low carb is pretty difficult, if not impossible, without starving oneself.

No, those are not links to studies, but you can Google this and find everything you need if you’re still not convinced.
I don’t eat low-carb and I don’t eat low-fat. I eat about 45% carbs, 30% protein, and 25% fat. The recommended intake is 50% carbs, 25% protein, and 25% fat. So, I just lowered my carb intake in order to increase my protein intake because I lift weights (not 10 lb weights, the ones that actually make a difference). I’m much more concerned if I go over my carb limit than I am if I go over my fat limit. When I eat foods high in good fats, I’m more satisfied after the meal than I would be if I ate something high in carbs – carbs lead me (and many others) to just eat more carbs, increasing my caloric intake by quite a bit. Now, carbs are super important before a workout and they give you energy for sure, but more fat and less carbs is definitely better than less fat and more carbs as far as weight management goes.
