Question 1

Is spot reduction possible?

Accepted Answer

It isn't. Fat decreases across the whole body together, and which area shrinks first follows an order you were born with.

Question 2

Why does the weight come back (the yo-yo effect)?

Accepted Answer

No. When you lose weight, the body treats it as a crisis and changes to use less energy. Burning less than before on the same amount of food is the body's basic response.

Question 3

Why does the same diet give different results for different people?

Accepted Answer

Because the reason the weight went up is different for each person. If the same method is used for someone who gained from eating a lot and someone who gained despite eating little, the results are bound to differ.

Question 4

What can and can't an obesity gene test tell you?

Accepted Answer

It can be a reference. But the test results won't tell you "this person should lose weight this way." It's honest to say that up front.
