I’ve wanted to lose 10 pounds (~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 objective. 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 number of weight simply to make dropping 10 kilos simpler. The concept felt much like racking up a ton of bank card debt to enjoy life to the fullest, then celebrating as soon as it was all paid off. I noticed folks do that on-line and get praised like heroes.
As a substitute of intentionally gaining weight, I ultimately determined it was more healthy to simply shed extra pounds. And surprisingly, all it took was lastly making use of two financial ideas: discount and substitution. As soon as I did, the load got here off in six months.
The Fundamental Financial Precept of Discount
As the worth of rises, the amount consumed tends to fall. This relationship is clearly illustrated by the traditional 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 cut back consumption by about 25–30 %.
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 greater costs as a forcing operate to eat much less. Fewer meals out will help us keep inside finances and, in lots of circumstances, enhance our well being as effectively. Decrease spending and higher self-discipline is a win-win final result.
Sure, combatting inflation is straightforward however not simple. As traders, we have been in a position to make good-looking returns lately, thereby making it simpler to splurge on meals. Nonetheless, as a rational economist, you alter your habits if you wish to change your final result.

We Ought to Have Consumed Much less Meals Throughout The Pandemic
Based mostly on the easy financial precept that greater costs ought to cut 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 diminished publicity danger, particularly since our daughter was born in December 2019 and had a still-fragile immune system.
The issue is that meals supply usually prices about 20% greater than choosing up the identical meal and roughly 50% greater than cooking at dwelling. With a new child and a three-and-a-half-year-old, we justified the premium as a needed time saver.
5 years later, we had been nonetheless ordering supply recurrently. Not solely is it costly, however restaurant meals can be typically much less wholesome, with greater ranges of added sugar and salt.
The Catalyst To Lastly Begin Dropping Weight: Much less Cash
To shed extra pounds, it helps to have a catalyst. Mine was spending five weeks with my parents 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. If you’re not making an attempt 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 at the least $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 remodel my parents in law 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 reworking a previous dwelling from 2019 to 2022.
As I watched the payments pile up, I turned conscious about each value round me. When bills rise, money movement obtainable for all the pieces 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 movement. For instance, as an alternative of spending $25 for an additional container of poke from Contemporary Catch, we made due with much less. The humorous factor is, in the long run, 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
After we returned from Hawaii, I lastly examined our meals spending carefully and was shocked. We had been spending round $3,500 a month on meals for a household of 4.
Though I manage our investments and generate supplemental retirement earnings by way of this website and ebook 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 all the pieces. Regardless that headline inflation has moderated, our meals prices are nonetheless roughly 40 % greater 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 value reminiscences is why all of us ought to conduct a deep financial review at least once a year. What we bear in mind is commonly disconnected from current actuality.
This is similar anchoring mistake many older generations make once they say issues had been low cost again of their day and that working tougher was all it took. They underestimate the compounding impression 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 largest substitution: going from meals supply to extra home-cooked meals.
Dwelling 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 bunch of wonderful eating places throughout each delicacies possible, all deliverable inside an hour.
In reality, I lately found a restaurant referred to as Khao Tiew that serves one of the best 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 on the spot 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 losing a few pounds. The saying is true: the digital camera actually does add 10 kilos.

So it’s again to writing and podcasting for me, the place the main focus is on concepts moderately than appearances. However in order for you motivation to shed extra pounds, movie your self and watch it.
Thank Goodness For Larger Meals Costs
If meals costs had been falling, meals consumption would logically rise. Good meals is difficult 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 less complicated. Meals that after value below $85 for our household of 4 now routinely exceed $140. At that time, rice porridge with hen and cabbage for $15 overlaying two days sounded nice.
Now that I’m used to a flatter abdomen, I’ve no need to return. My endurance on the courtroom has improved and I really feel fitter general. As Steven Tyler as soon as stated, “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 needed. That is the issue with residing in America given there may be an abundance of all the pieces.
