GI, Insulin and Fat: Exploring Effects on Body Weight

[Jikx]

The problem with junk food is the high sugar, fat and sodium content. The sugar releases insulin, the fat is absorbed and you get fat simple as that.

I'm trying to understand what a person said (from ahttp://forums.whirlpool.net.au/forum-replies.cfm?t=162168&p=4 . Later on, he goes to say that without insulin, eating excess fat would not cause you to get fat (near the bottom of the page).

I'm confused... I'm sure insulin regulated the blood-sugar level by causing select cells to increase their uptake of glucose, and to absorb fatty acids. But say if a person ate lard - and nothing but, would this person still store the fat? Or does consumption of fat induce the production of insulin, which then causes cells to store it?

thanks! Everything I've searched only shows insulins effect on glucose.

To an extent what he said was true. Obviously, over induldging in fat will make you fat with or without the presence of insulin.

But, I have seen people eat as many as 500 grams of protein and 200 grams of fat per day and actually loose body fat.

The benefit and problem with insulin is that it is and extremely strong anabolic. It is anabolic for not only muscle but, also, for fat. Any excess carbs will be more readily stored as fat.

Of course, after an intense workout and depletion of glycogen, one can shoot 15 to 20 ius of insulin, intake 200 grams of high glycemic carbs and protein and build more muslce than one could with the use of AAS.

Thank you for bringing up this interesting topic. It is true that junk food, which is high in sugar, fat, and sodium, can contribute to weight gain. This is because the sugar in junk food causes a spike in insulin levels, which can lead to fat storage in the body. Insulin is a hormone that helps regulate blood sugar levels by promoting the uptake of glucose and fatty acids into cells.

In the scenario you mentioned, if a person were to only eat lard, they would still likely experience weight gain. This is because consuming any type of calorie-dense food, regardless of its source, can lead to an increase in insulin levels and subsequent fat storage. However, it is important to note that the type of fat consumed can also play a role in weight gain. Unsaturated fats, found in foods like avocados and nuts, are less likely to contribute to weight gain compared to saturated fats found in foods like lard.

It is also worth mentioning that insulin is not the sole factor in weight gain. Other factors such as overall calorie intake, physical activity, and genetics also play a role. Therefore, it is important to maintain a balanced and healthy diet, rather than solely focusing on one specific macronutrient like fat or insulin.

In summary, while insulin does play a role in fat storage, it is not the only factor. A diet high in junk food, which is typically high in sugar and fat, can lead to weight gain due to the spike in insulin levels and subsequent fat storage. It is important to maintain a balanced and healthy diet to support overall health and weight management.
