It contains two key ingredients, a synthetic hormone that tells your brain you’re full, one we create naturally when we are full but many of us not enough of, obviously and it slows down put digestion, so that food remains in our digestive tracts and stomach longer, thus aiding us to feel full longer.
with this, we don’t want to eat as much, so we lose weight. And it also stabilises insulin, so it’s easier to lose weight.
I take physlium husk, some folks take prunes or figs, others fibro gel to stop them getting constipated, as our digestion is slower.
but basically your brain tells you you are not hungry till you are.
edit just eat normally but try to avoid fatty or too much carby food as it can make you get the runs or feel sick for some. People take protein shakes as it’s important to keep your protein up so you don’t lose muscle mass.
