I’ve wished to lose 10 kilos (~6% of physique weight) ever since I began Monetary Samurai in 2009. I’ve come shut, dropping 5 to 6 kilos in some years, however by no means fairly hitting the double digit purpose. Consequently, for greater than 16 years, I failed to perform one thing that ought to have been simple, particularly for a supposedly rational economist and private finance nerd.
There have been even moments after I thought of deliberately gaining a variety of weight simply to make dropping 10 kilos simpler. The concept felt just like racking up a ton of bank card debt to take pleasure in life to the fullest, then celebrating as soon as it was all paid off. I noticed individuals do that on-line and get praised like heroes.
As a substitute of intentionally gaining weight, I finally determined it was more healthy to simply reduce weight. And surprisingly, all it took was lastly making use of two financial rules: discount and substitution. As soon as I did, the burden got here off in six months.
The Primary Financial Precept of Discount
As the worth of a superb rises, the amount consumed tends to fall. This relationship is clearly illustrated by the basic supply-and-demand curve.
If every meal prices $25 and I’ve $100 to spend on meals, I should purchase 4 meals. If the worth per meal rises to $33.34, that very same $100 solely buys three meals. With a hard and fast finances, the rational shopper should scale back consumption by about 25–30 p.c.
The place we get into bother financially is ignoring this precept. As a substitute of adjusting habits, we pay $134 for 4 meals, take in the upper value, after which complain about meals inflation.
A extra constructive response is to make use of larger costs as a forcing operate to eat much less. Fewer meals out might help us keep inside finances and, in lots of instances, enhance our well being as nicely. Decrease spending and higher self-discipline is a win-win end result.
Sure, combatting inflation is simple however not simple. As traders, we have been capable of make good-looking returns in recent times, thereby making it simpler to splurge on meals. Nevertheless, as a rational economist, you modify your habits if you wish to change your end result.

We Ought to Have Consumed Much less Meals Throughout The Pandemic
Based mostly on the straightforward financial precept that larger costs ought to scale back consumption, I ought to have misplaced a ton of weight through the pandemic.
As a substitute, beginning in 2020, our meals spending climbed quickly as we ordered extra supply. On the time, it made sense. Supply saved time and decreased publicity threat, particularly since our daughter was born in December 2019 and had a still-fragile immune system.
The issue is that meals supply sometimes prices about 20% greater than choosing up the identical meal and roughly 50% greater than cooking at house. With a new child and a three-and-a-half-year-old, we justified the premium as a mandatory time saver.
5 years later, we had been nonetheless ordering supply repeatedly. Not solely is it costly, however restaurant meals can be usually much less wholesome, with larger ranges of added sugar and salt.
The Catalyst To Lastly Begin Dropping Weight: Much less Cash
To reduce weight, it helps to have a catalyst. Mine was spending 5 weeks with my dad and mom in July 2025. My dad, who’s about six ft tall and weighs roughly 155 kilos, referred to as me chubby. Thanks dad. I fired again that he ought to placed on some weight and muscle.
However deep down, I knew I might stand to lose some weight. On the time, I used to be 5 foot ten and weighed 172 kilos. There’s nothing like going to Hawaii and having to take your shirt off on the seashore to make you confront extra weight. In case you are not attempting to draw a mate, the pure tendency is to let your self go as a result of you have already got one.
As a result of we stayed with my dad and mom, we saved a minimum of $20,000 in lodging prices. Initially, I solely had meals and transportation bills to fret about. That modified as soon as I made a decision to rework my dad and mom in regulation unit. What I believed would value $25,000 ended up costing $41,000. It was probably the most cash I had spent in a four-week interval since transforming a previous house from 2019 to 2022.
As I watched the payments pile up, I turned aware of each value round me. When bills rise, money circulate obtainable for every little thing else shrinks. And one of many few actually versatile bills left was meals.
Consequently, I deliberately determined to spend much less on meals to enhance money circulate. For instance, as an alternative of spending $25 for an additional container of poke from Recent Catch, we made due with much less. The humorous factor is, ultimately, my dad and mom ended up footing 85% of the rework invoice. I simply did not anticipate them to, which is why I lowered my bills.

A Cautious Inspection Of Our Meals Price range
Once we returned from Hawaii, I lastly examined our meals spending intently and was surprised. We had been spending round $3,500 a month on meals for a household of 4.
Though I handle our investments and generate supplemental retirement revenue by this website and guide writing, I don’t actively handle our family bills.
In my head, I believed we had been spending round $2,500 a month on meals. Inflation that accelerated after 2021 modified every little thing. Though headline inflation has moderated, our meals prices are nonetheless roughly 40 p.c larger than they had been 5 years in the past.
Mentally, I used to be caught in a a lot earlier pricing period till I confronted the precise numbers. Inflation has an effective way of sneaking up on us.
Including Substitution To Lose Weight
Anchoring to outdated worth reminiscences is why all of us ought to conduct a deep monetary assessment a minimum of annually. What we bear in mind is usually disconnected from current actuality.
This is identical anchoring mistake many older generations make after they say issues had been low cost again of their day and that working tougher was all it took. They underestimate the compounding affect of inflation relative to wages.
As soon as I understood our true spending, my spouse and I created a month-to-month meals plan. Our goal was to return to $2,500 a month and save $1,000 a month whereas consuming more healthy. That meant consuming much less, but in addition substituting.
The most important substitution: going from meals supply to extra home-cooked meals.
Residing in San Francisco, a prime three meals metropolis within the nation, makes this tougher. We construct the know-how that makes meals supply handy. We’re additionally surrounded by a whole lot of wonderful eating places throughout each delicacies conceivable, all deliverable inside an hour.
In reality, I lately found a restaurant referred to as Khao Tiew that serves the perfect khao soi I’ve ever had. Sadly, when you add boneless beef brief rib and tax, the dish runs about $28 for pickup. So for now, I’ve changed it with $1.49 immediate ramen noodles and name it a lesson in self-discipline. Substitution child!

Then Business Insider got here by to interview me about saving cash whereas elevating a household. Once I noticed myself on digital camera, I felt newly motivated to maintain reducing weight. The saying is true: the digital camera actually does add 10 kilos.

The expertise additionally bolstered my want to not pursue video to not fall into the entice of exterior validation. So it’s again to writing and podcasting for me, the place the main target is on concepts moderately than appearances. However if you need motivation to reduce weight, movie your self and watch it.
Thank Goodness For Increased Meals Costs
If meals costs had been falling, meals consumption would logically rise. Good meals is tough to withstand. However after I watched my favourite steak on the grocery store go from $28 a pound to $32 after which $39, I ended shopping for it. First I substituted with $12 cheeseburgers. Then I started lowering the consumption of meat altogether.
As supply charges and menu costs climbed, opting out altogether turned easier. Meals that after value below $85 for our household of 4 now routinely exceed $140. At that time, rice porridge with rooster and cabbage for $15 overlaying two days sounded nice.
Now that I’m used to a flatter abdomen, I’ve no want to return. My endurance on the courtroom has improved and I really feel fitter general. As Steven Tyler as soon as mentioned, “nothing tastes nearly as good as skinny feels.”
Though paying extra for meals is disagreeable, I’m oddly grateful. For too lengthy, I lived comfortably with out scrutinizing my meals spending and ate no matter I wished. That is the issue with dwelling in America given there’s an abundance of every little thing.
