Losing fat is very easy. Via negativa.
Stop eating sugar, fruit, vegetables, starches, bread rice and potatoes. Stop drinking anything with sweeteners, artificial or real. No honey, no Monk fruit, none of that nonsense.
Don’t eat sauces, 99% of them have sugar added.
Also, don’t eat more than once a day. Fast. No breakfast no lunch, only one massive dinner a day.
Also, stop eating desserts, snacks, beverages, alcohol, weed, etc.
