Oscar Poon
Founder of LS Diet · Creator of the Weight Permanence Training™
Oscar Poon is the founder and creator of LS Diet. He has lost 80+ lbs three separate times — and each restart was a tuition payment that eventually became the method he teaches now. The diets worked. The behavioural infrastructure underneath them did not. That gap is what LS Diet exists to close.
Today Oscar shares the low-starch, low-sugar lifestyle and the Weight Permanence Triangle™ through monthly mini-challenges on YouTube (@JoinLSDiet), a weekly live webinar, and the free LS Diet course. The work is deliberately oriented around people who have already lost weight and don't want to do it again.
Background and Method
Oscar holds a degree in psychology and spent over a year supporting clients at a substance-abuse centre in Vancouver. That work shaped how he thinks about cravings, identity, and relapse — the vocabulary of addiction recovery maps almost directly onto the cycle of losing and regaining weight. He also spent a decade as a surgical market-data consultant, which trained him to see patterns in messy human behaviour and to design systems that hold up in real environments rather than ideal ones.
That mix — clinical psychology plus pattern analysis — is what makes LS Diet structurally different from typical diet content. The food framework is intentionally simple. The behavioural framework is where the real engineering lives. Read the breakdown on the Weight Permanence Training™ page, the 5 Awareness Stages, or the What Is LS Diet overview.
Why He Built LS Diet
After the third restart, Oscar stopped looking for a better diet and started looking for the missing layer underneath every diet he had tried. The pattern was always the same: the food worked while life was calm; the food collapsed when life wasn't. The intervention had to operate above food, not below it. LS Diet is the result — a low-starch, low-sugar lifestyle paired with awareness work, daily practice, and permanence systems that course-correct early instead of demanding another restart.
