I've weighed 135 pounds most of my adult life. I told myself I'd gain 20 pounds to see what it felt like, then lose it all. Now I'm 155 but I don't feel very different. My new goal is 175, but I'm afraid if I get there I won't be able to lose the weight afterwards.
If you're having doubts, it's better not to go down that road in the first place. Your body has a set point and, as you gain weight, that set point is adjusted higher. This means your body will prefer to be at a certain weight and, if you try to lose weight through diet and exercise, your body will tend to regain the weight once you stop dieting.
I'm a perfect example of this. I started gaining weight at 166 pounds. Through a combination of heavy whipping cream and dieting in between gaining cycles, I'm not at 282 pounds.
When I "diet" between gaining cycles, I just eat the same amount and types of foods that I ate at 166 pounds, which is what I normally eat anyway. I rely exclusively on the heavy whipping cream to gain weight.
Thanks to gaining weight, my set point was 260 pounds prior to my current gaining cycle. So even when I returned to eating what I normally at at 166 pounds, my body weight would not drop down below 260 pounds. My body wants to stay at 260 pounds. I would need to try very hard to lose weight and get below 260 pounds.
This is why it's important to be sure. Once you start gaining and increasing your set point, it's very hard to lose the weight and, even after losing the weight, your body will try to return to it's set point. This is why yo-yo diets fail.
As far as I know, the set point only goes up, not down. I hope this helps.
