View Full Version : When you eat fat, is it always stored if it isn't used?

For example, if you eat a certain amount of fat in a day, is the excess fat that isn't used for the body stored as fat? Is it ever used as energy throughout the day or only on a calorie deficit?

Also, when you do cardio, is carbs always used for energy, is fat being burned at the same time but less?

Excess calories get turned to fat, not excess fat.

Also, carbs are used as an energy source when doing cardio. The point in cardio is burning calories, so yes it will burn fat. No matter what you ate that day you'll still burn the same amount of fat doing cardio because thats the amount of calories you burned.

Complicated question. However not too hard to simply for our purposes.

Carbohydrates are the preferred fuel source. Dietary fat is most easily stored as adipose tissue (compared to CHO and P). Your body will seek to use the energy (calories) that you've taken in, preferably CHO, F, P in that order.

Dietary fat is targeted for storage in fat cells when eaten, but that still doesn't mean it makes you fat. Like rhadam said, your body will preferentially burn carbs over fat.

For the second question, someone will correct me if im wrong but I believe during low intensity activity your body primarily uses fat for fuel, whereas during vigorous activity it will use glucose.

TLDR: Easier stored than carbohydrates (in a surplus).

then why people go .5 x bodyweight? isnt that a lot of fat? (example 80 grams)

Total calories is more of a determining factor of weight gain/loss. We seek to hit a minimum fat level (.45g), after that it's not a huge deal for the most part.

in other words keto bulk is a no no?

Not necessarily, at the end of the day it's all personal preference.

Excess fat is used to replenish already drained fat stores as you burn fat 24/7 , as others have said it's the positive or negative energy (calorie) balance that dictates net body fat loss/gain. You only gain "more" body fat when you have an excess of calories.

The fuel being utilized doing cardio depends on the intensity, high intensity (sprints/HIIT/running etc.) is mostly carbs, lower intensity increases the fat utilization. But low intensity cardio doesn't mean you burn more fat overall, again its the total energy balance that dictates loss/gain of body fat.

Worry less about dietary fat and more about the energy balance (calories in vs calories out), but if you are going to overeat on something then carbs or protein are the "best" option as they require more energy to store as body fat and is likely to go to glycogen replenishment instead (not really valid during a bulk as stores are pretty much full all the time in a surplus).

All fat finds its way to the adipose tissue before being oxidised as energy.

However, it's total NET turnover of fat that determines if you "get fat".

Fat burning happens continuously through the day although it is blunted by carb and/or protein consumption and subsequent storage of glycogen.

Bottom line: you don't even need to know this is happening. It's all about calories in and calories out.

This ^ OP.

I'm currently gaining weight slowly on ~3300 kcal, ~150 gram fat. I have no problem staying lean.

Keep in mind when in surplus saturated fats are more likely to lead to increased body fat than unsaturated fats.
