Taste is an important sense in people and many animals. Many people believe that there are four kinds of taste -- salt, sour, sweet, and bitter. But the cells that make up the taste buds do not have structural or functional differences that correspond to these tastes. Taste buds are grouped on the tongue into small mounds called papillae. Each taste bud contains a number of receptor cells. The papillae on the front part of the tongue have their receptor cells connected to one nerve. The papillae on the edges of the tongue -- about halfway between front and back -- and those at the back of the tongue are connected to a second nerve. We also have taste buds in the soft palate (back of the roof of the mouth) and other parts of the mouth.
When we take food into our mouths, the exposed ends of the taste bud receptor cells contact molecules from the food. The receptor cells transmit information about the chemicals in the food to the nerves. Different taste nerves may respond differently to the same chemicals. Also, small amounts of some chemicals are more easily tasted on the front of the tongue, and others are more easily tasted on the back or sides of the tongue.
The nerves from the taste buds come together at the back part of the brain stem. Here, some taste signals carried by the nerves are separated according to the nerve involved, as well as by the different chemicals they respond to. The taste signals then travel to the front of the brain stem, the thalamus. From the thalamus, the signals move to the cerebral cortex of the brain. At the cerebral cortex, the brain interprets the nerve impulses it has received, and we become aware of taste.
Sweet chemicals stimulate special taste buds on the tongue and stimulate maximum number of sensory receptors, which impart taste sensations on the surface of the tongue. Our sense organs discharge electrical impulses that convey messages to the brain telling us those sweets are indeed sweet. But the maximum stimulation of receptors brings about a saturation point, and there follows a refractory or rest phase, during which further stimulation of receptors will prove ineffective. So after relishing on something sweet, when you taste other sweetened food, you will not find it sweet. Once this phase passes off, the taste buds are ready to work again.

It is the function of taste bud.
There is a response time and if you eat the same dish you will experience the sweetness, if you eat the same dish that is less sweet then you will not be able to taste the sweetness.
This is actually true of all tastes, but most can detect sweet taste more readily.

A lot of frozen yoghurts have added sweeteners and very little fat. Along the frozen line again (sorry this is fruit :) ) fruit smoothies made with ice don't really taste like fruit. I know my sisters put chocolate in the freezer making one block last a lot longer or you could face the consequences of broken teeth :P I think the best bit of advice I can give is to still eat sweet things but in moderation. In my experience if you totally cut something from your diet you'll end up craving it then end up eating it by the bucket load.

Sweet carries all the sweetness away.
