Evolution hasn't stopped.
The frequency of alleles in species continue to change due to selection pressures
from their environments.
DNA continues to undergo random mutations that create new alleles for evolution to
work on.
This will stop if and only if we start directly genetically engineering species so that

We evolve.
Deal with it.

... Also how do you 'look' lazy?
100 years is only about 4 generations... which isn't very much time for evolution to act
particularly without any strong environmental selection pressure.
However it could equally go the other way, if being considered 'sexy' is an important
factor in reproducing and being 'sexy' requires being slim then there is a selection pressure
for those that keep themselves slim.
Of course there could also be the scenario where humanity splits into two species one which
values slimness and one which values plump 'curvyness'.
If the two groups keep the cross mating to a minimum after enough time they will diverge
from one another enough that they will no longer be able to successfully mate and produce
viable offspring.
Of course we are likely to take over our own genetic future long before that could ever happen,
but we haven't done that yet.
