Is the Freshman 15 actually real?

It is directionally real but roughly a third the size of the myth. Vella-Zarb & Elgar 2009 (Journal of American College Health) meta-analyzed the first-year college weight-gain literature and found an average gain of about 3.5 to 4.5 lb across the freshman year — not 15. Vadeboncoeur 2015 (BMC Obesity) updated the meta-analysis across 32 studies and confirmed an average of roughly 3.4 lb. Racette 2005 (Journal of American College Health) followed a University of Missouri cohort across all four years and found gains kept accumulating at roughly 2 lb per year, so a total of about 9 lb across the four-year window is a more accurate framing than a single freshman-year hit. The number is not 15, but it is not zero, and the trajectory continues past freshman year — which is why the interventions in this article are written for a four-year, not a first-semester, window.

What actually causes weight gain in college?

Four drivers do most of the work. First, the unlimited-portion dining-hall environment — Wansink 2007 (Obesity) documented how self-serve buffets and hidden portion norms push intake up without conscious awareness. Second, alcohol — at 7 kcal per gram, drinking calories add up quickly, and Small 2013 (Journal of American College Health) linked heavier drinking patterns to higher weight in college students; NIAAA's 2024 College Drinking fact sheet has the prevalence data. Third, the 6-hour sleep pattern — Nedeltcheva 2010 (Annals of Internal Medicine) found that shortening sleep from 8.5 to 5.5 hours dropped the fraction of weight lost as fat from about 55 percent to 25 percent during a controlled deficit, with hunger and preference for hyperpalatable foods rising as sleep fell. Fourth, the late-night delivery-app window — DoorDash and Uber Eats at 2 a.m. is a genuinely new environmental input in the last decade. Notice what is not on the list: 'not enough gym time' and 'metabolism.' Both are essentially non-factors at this age.

How do I not gain weight from the dining hall?

Use the plate-composition rule: half the plate produce (leafy salad, roasted vegetables, cooked greens, fruit), a quarter of the plate protein (grilled chicken, fish, eggs, tofu, beans), and a quarter of the plate starch (rice, pasta, potato, bread). At the salad bar, dressing goes on the side — the 700-kcal 'salad' (ranch, croutons, cheese, bacon bits, dried cranberries, sunflower seeds) is a real trap, not a stereotype. For breakfast, prefer the omelette station over the french-toast station most days. When the meal is pizza and fries, eat it and reset at the next meal — one meal does not undo a semester. Eat one piece of fruit sitting at the table before dessert; that single micro-protocol replaces most dessert plates. And ignore the endless second-serving option most nights — Hoerr 2009 (Journal of the American Dietetic Association) mapped how the dining-hall food environment shapes choice more than the individual student does. See the [social eating and weight loss](/weight-loss/social-eating-and-weight-loss/) piece for the group-pressure layer that sits on top.

How much does alcohol matter for weight in college?

More than most students realize, but not for the reason usually cited. The calories add up (light beer ~100 kcal, regular beer ~150 kcal, 5 oz wine ~120 kcal, a mixed drink 200 to 400 kcal, White Claw ~100 kcal) — a 4-drink night is a real 600 to 1,200 kcal on top of your day. But the bigger driver is the disinhibition amplifier: Small 2013 (Journal of American College Health) documented how alcohol reliably increases late-night food intake beyond the drink calories themselves — the 1 a.m. pizza-and-cheese-fries order after the bar is the actual mechanism, not the beer itself. Two harm-reduction defaults that work for most students: cap drinking to two nights a week rather than aiming for abstinence, and pre-plan the drunk-food option (one slice of pizza plus water at 1 a.m. is a plan; a full order of everything is what happens without a plan). See [alcohol and weight loss](/weight-loss/alcohol-and-weight-loss/) for the full per-drink table and the sleep-quality interaction.

Can I lose weight in a dorm with no kitchen?

Yes, and you do not need to cancel your meal plan or buy a hot plate. Seven no-oven, mini-fridge-friendly protein staples cover most protein needs: Greek yogurt (17 g per 6 oz), cottage cheese (14 g per half cup), hard-boiled eggs sold pre-peeled (6 g each), string cheese (7 g per stick), beef or turkey jerky (10 g per oz), foil tuna pouches (17 g per pouch), and whey or plant protein shakes (20 to 25 g per scoop or bottle). Pair with pre-cut fruit, bagged salad kits, roasted chickpeas, or the fruit and pre-made salad options at the dining hall. Cost-per-gram-of-protein winners at 2026 pricing are usually eggs, cottage cheese, and jerky. Skip the giant Costco tub of cookies for the same reason it is a bad idea anywhere else — availability drives intake. See [meal prep for weight loss](/weight-loss/meal-prep-for-weight-loss/) for the fuller batch-cooking protocol if you eventually move to an apartment kitchen.

Do I need a gym membership to lose weight in college?

No — most colleges include full rec-center access with tuition, and most students already walk 7,000 to 9,000 steps a day just moving between dorm, classes, and dining hall. Two moves cover the base: use the campus rec center 2 to 3 times a week for a simple strength routine (squat, hinge, push, pull, carry — see [strength training for weight loss](/weight-loss/strength-training-for-weight-loss/)), and add one intentional walk a day (to a distant coffee shop, around the quad after dinner, to a friend's dorm instead of texting). For the days you cannot get to the rec center, a 5-move dorm bodyweight routine works — push-ups, squats, walking lunges around the room, glute bridges, and a plank — see [home workouts for weight loss](/weight-loss/home-workouts-for-weight-loss/) for the full progression. Do not pay for ClassPass, Peloton, or a nearby commercial gym in your first year; the campus infrastructure is already paid for.

Weight Loss for College Students: The Dorm-Kitchen Playbook, the Dining-Hall Rules, and What the “Freshman 15” Actually Is (2026)

Quick answer

The Freshman 15 is a myth in magnitude but a real directional signal. Vella-Zarb & Elgar 2009 (Journal of American College Health) meta-analyzed the first-year college weight-gain literature and found an average gain of about 3.5 to 4.5 lb — not 15; Vadeboncoeur 2015 (BMC Obesity) updated the meta across 32 studies and landed near 3.4 lb; Racette 2005 (Journal of American College Health) followed a University of Missouri cohort across all four years and found gains continued at roughly 2 lb per year, so the four-year window is a more honest framing than freshman fall alone.

The four actual drivers are (1) the dining-hall unlimited-portion environment (Wansink 2007 Obesity, Hoerr 2009 J Am Diet Assoc), (2) alcohol calories plus disinhibited late-night eating (Small 2013 J Am Coll Health; NIAAA College Drinking Fact Sheet 2024), (3) the 6-hour sleep pattern (Nedeltcheva 2010 Ann Intern Med — a 5.5-hour sleep protocol dropped the fat-loss fraction of a controlled deficit from 55% to 25%), and (4) the 2 a.m. delivery-app window that did not exist a decade ago. ACHA-NCHA-III 2023 documented the sleep and stress prevalence in the current undergraduate population — the numbers are worse than most students think.

This pillar is a no-gym-membership-required, no-meal-plan-cancellation, no-shame starter frame. If you are between teen weight-management questions and post-college adulthood, this is your page; the adolescent and teen weight management piece covers the years before college, and weight loss for women in their 30s and weight loss for men pick up after graduation. Body-image, comparison, and disordered-eating flags get their own sections below — those matter more at this age than any specific meal-plan tweak.

What the Freshman 15 actually is — the evidence walk-through

The number 15 entered public conversation as a Seventeen magazine headline in the late 1980s. It was never a research finding. The best current evidence:

• Vella-Zarb & Elgar 2009 — meta-analyzed the freshman-year weight-gain literature and found an average gain of about 3.5 to 4.5 lb across the freshman year, not 15. The paper explicitly named the “Freshman 15” as a myth in magnitude.
• Vadeboncoeur 2015 — updated the meta with 32 studies, confirmed a mean gain of about 3.4 lb, and noted meaningful individual variance (some students lose, some gain 10+ lb, most cluster near the 3-to-5-lb average).
• Hoffman 2006 (J Am Coll Health) — Cornell cohort of freshman students, gain concentrated in the first semester.
• Racette 2005 — 4-year University of Missouri cohort. Average gain ~9 lb across the four years, with roughly 2 lb per year drift continuing past freshman year. This is the number worth planning for, not the freshman-only number.
• Nelson 2008 (Obesity) — Project EAT longitudinal cohort followed adolescents into young adulthood and found the college transition is a real behavior-shift window with weight consequences that extend beyond freshman year.
• Deforche 2015 (Int J Behav Nutr Phys Act) — mapped the behavioral drivers of gain during the college transition (dietary changes, physical-activity decline, alcohol, sleep).

The honest read: the Freshman 15 is closer to a Freshman 3.5 to 4.5, and the four-year drift is closer to 8 to 10 lb on average. That is not nothing — it is what makes the interventions worth doing — but it is also not the catastrophic-cliff framing the myth carries. Correcting the myth without dismissing the reality is the frame this article uses throughout.

The 4-driver mechanism

Most college weight gain runs through four separable drivers. Naming them removes the shame that any single one is a personal defect — they are documented pathways.

Notice what is not on the list: “not enough gym time” and “metabolism.” Both are essentially non-factors at this age. Time in the gym helps with body composition and mood — see strength training for weight loss — but the gain-vs-not-gain outcome is decided in the dining hall, the bar, the bed, and the phone.

The 5-scenario decision table

Every student’s context is different. The five most common setups, with per-scenario rules:

If you are in more than one scenario (commuter with a meal plan; international apartment renter), pick the row that best captures your evening — evening is where most weight moves in this age group.

Dining-hall specific rules

The dining hall is the biggest single environmental input for most students on meal plans. Six rules cover most of the terrain:

• Plate-composition rule. Half plate produce (leafy salad, cooked vegetables, fruit), a quarter plate protein (grilled or baked; not fried), a quarter plate starch (rice, pasta, potato, bread). The plate is your external stop signal — no seconds until you have finished what is on it and asked “am I actually still hungry?”
• The salad-bar caloric trap. A “salad” of ranch dressing, croutons, shredded cheese, bacon bits, dried cranberries, and sunflower seeds on a base of iceberg is a ~700 kcal meal that reads as “healthy.” Rule: dressing on the side, cheese or nuts or dried fruit (pick one), and a base of dark leafy greens not iceberg. Hoerr 2009 documented how the salad-bar environment reliably shapes choice more than intent.
• Omelette bar > french-toast bar on most mornings. A 3-egg omelette with vegetables and a small side of fruit is roughly 400 kcal with 20+ g of protein; two pieces of french toast with syrup and butter is roughly 700 kcal with 8 g of protein. Once a week for french toast is fine; every day is the pattern.
• Pizza-and-fries reset rule. When the meal is pizza and fries — because the friend group picked the pizza night or the alternatives are unappealing — eat it and reset at the next meal. One meal does not undo a semester. The 3-day “compensating” restriction pattern is what actually leads to weekend overshoot.
• Fruit-before-dessert micro-protocol. Sit at the table with one piece of fruit before you get a dessert. Most nights the dessert plate doesn’t happen. Wansink 2007-style micro-interventions like this work through mild friction, not willpower.
• Second-plate audit. Before returning for a second full plate, drink a full glass of water and ask “am I still physically hungry, or is this just because the food is free and endless?” If yes, go get it. If uncertain, wait 10 minutes.

See social eating and weight loss for the group-pressure layer that sits on top of dining-hall rules — eating with a table of 6 friends is different from eating alone, and the peer-facilitation-of-eating effect is real.

Alcohol — the honest per-drink picture

Alcohol is the single largest weight-relevant variable most students underestimate. The math and the mechanism both matter.

Per-drink calories (approximate):

• Light beer (12 oz): ~100 kcal
• Regular beer (12 oz): ~150 kcal
• IPA / craft beer (12 oz): 180 to 250 kcal
• Wine (5 oz): ~120 kcal
• White Claw / hard seltzer (12 oz): ~100 kcal
• Vodka soda (1.5 oz spirit + soda): ~100 kcal
• Rum & coke: ~200 kcal
• Margarita (frozen): 300 to 500 kcal
• Long Island iced tea: 400+ kcal

A “four-drink night” is a real 400 to 1,600 kcal depending on what those four drinks are — the range is enormous, and most students underestimate the top of it.

The disinhibition amplifier. The direct calories are only part of the story. Small 2013 (J Am Coll Health) documented that alcohol reliably increases late-night food intake beyond the drink calories themselves — the 1 a.m. cheese-fries-and-pizza order after the bar is the actual mechanism. Alcohol lowers inhibitory control over food choice for several hours; the “drunk food” is often bigger than a whole normal dinner.

Two-nights-a-week default. Full abstinence is a reasonable choice; most students will not make it. A harm-reduction default of two drinking nights per week with 1 to 4 drinks each is a target most college students can hold and that materially changes the calorie math. This is the same framing the alcohol and weight loss article uses for adult drinkers.

Pre-plan the drunk-food option. A single slice of pizza plus a full glass of water at 1 a.m. is a plan. A full order of loaded fries plus a burrito plus mozzarella sticks is what happens without a plan. Decide before you go out. Save $8 and 900 kcal.

NIAAA College Drinking Fact Sheet 2024 has the current prevalence numbers on binge drinking (defined as 4+ drinks for women, 5+ for men in a 2-hour window), which remains high among undergrads. If your drinking is on the wrong side of that line 3+ nights a week, that is a health issue past just weight — the NIAAA site has screening tools and campus-based resources.

Dorm-cooking micro-section — 7 no-oven, mini-fridge staples

If your dorm has only a mini-fridge, a microwave, and possibly a hot pot or electric kettle, these seven staples cover most protein needs at student-friendly cost. Prices are approximate for 2026 at a typical campus grocery or Target.

Pair those with pre-cut fruit, bagged salad kits, roasted chickpeas, apples, bananas, baby carrots, cherry tomatoes, and the fruit or pre-made salad options at the dining hall. Skip the giant Costco tub of anything you don’t want to eat in one sitting — availability drives intake in a 12-by-12 dorm room more than anywhere else. See meal prep for weight loss for the fuller batch-cooking protocol once you move to an apartment kitchen.

Free (or near-free) campus movement

Most college students already walk 7,000 to 9,000 steps a day — the walk between the dorm, three classes, the dining hall, and the library is a real activity baseline that adults working desk jobs would kill for. Don’t undervalue it. Do not sit in one spot for six hours to “make up for” a missed workout; the daily walking baseline matters more than a single gym session.

The campus rec center is included in your tuition. Use it 2 to 3 times a week. A simple, boring, effective routine at this age:

• Squat variation (goblet squat, back squat, or bodyweight)
• Hinge (Romanian deadlift, hip thrust, or good morning)
• Push (push-up, dumbbell bench, overhead press)
• Pull (row, lat pulldown, or pull-up)
• Carry or core (farmer’s carry, plank, or dead bug)

Three sets of 8 to 12 reps each. Forty-five minutes. That is the whole plan. See strength training for weight loss for progression logic.

Dorm bodyweight routine — 5 moves, 20 minutes, no equipment:

1. Push-ups (or knee push-ups): 3 sets of 8 to 15
2. Bodyweight squats: 3 sets of 15 to 25
3. Walking lunges around the room: 3 sets of 20 total steps
4. Glute bridges: 3 sets of 15 to 20
5. Plank: 3 sets of 30 to 60 seconds

Do this the mornings you cannot make the rec center. See home workouts for weight loss for the full progression and equipment-free alternatives.

Walking for weight loss. Add one intentional walk a day on top of your baseline — around the quad after dinner, to a coffee shop 20 minutes away, from the far parking lot to class. Steps are the most reliably logged variable at this life stage because your phone is already in your pocket. See walking for weight loss for the step-target and pace math.

Sleep and stress — the carveout most students skip

ACHA-NCHA-III 2023 collected the current undergraduate prevalence data on sleep and stress. The numbers are worse than most students think — roughly a third of undergraduates report clinically significant stress, and average self-reported sleep is well below the 7-hour recommendation.

Nedeltcheva 2010 (Annals of Internal Medicine) is the mechanism paper worth reading if you read only one for this section: shortening sleep from 8.5 to 5.5 hours in a controlled deficit dropped the fraction of weight lost as fat from ~55% to ~25% — meaning more of the loss came from muscle rather than fat when sleep was short. Hunger and preference for hyperpalatable foods rose. The plain-English version: you cannot out-diet a 5-hour-sleep schedule.

The workable college targets:

• A 7-hour floor 4 or more nights a week. Not every night — that’s not realistic for most college students. Four is.
• Caffeine cutoff by 2 pm. A 5 pm coffee at 21 is still in your system at midnight.
• No all-nighters as a rule (single crunch weeks aside). The all-nighter costs more than it saves — the exam grade advantage is small and the recovery hit is large.
• Screens off 30 minutes before sleep. If unrealistic, at least use night mode.

See sleep, stress, and weight management for the fuller sleep-and-cortisol protocol.

Failure modes — the four patterns to name

Almost every college weight-loss attempt that goes wrong runs through one of four failure modes. Naming them ahead of time is the intervention.

“I skipped the meal plan and gained more.” Canceling the meal plan sounds like control but usually removes the structured 3-meal-a-day scaffold and replaces it with an unstructured eating environment that runs on convenience. The meal plan, used well, is a feature — a paid-for external structure that would cost a working adult a personal chef. Keep the meal plan; use the rules above.

“I did keto in the dorm.” Keto has the poorest social-adherence profile of any popular diet in the college environment — every dining-hall meal, every group dinner, every study snack, every drink at a bar is a compliance test. Adherence collapse plus a rebound is the modal outcome. Sustainable at this life stage means socially compatible. If a diet cannot survive a Thursday-night group dinner at Chipotle without you having a moral crisis, it will not survive the semester.

“I took Adderall (or another stimulant) and now I can’t sleep and my body composition is worse.” Stimulants suppress appetite acutely and undereating during the day plus overshoot at night plus poor sleep is a real body-composition problem, especially when the stimulant is being used off-label for exam periods. If prescribed stimulants are causing sleep and eating disruption, that is a conversation with your prescriber, not something to push through. Non-prescribed use is a separate issue — see campus health services. The ADHD and weight loss piece covers the prescribed-medication interaction in detail.

“I have an eating disorder or restrictive pattern.” College is a peak-incidence window for eating disorders — anorexia, bulimia, binge eating disorder, ARFID, and orthorexia all cluster in the 18-to-24 age range. If you are restricting to below 1,200 kcal, weighing yourself more than once a week, exercising to “burn off” food, purging in any form, or binging weekly or more, please treat this as a medical issue rather than a discipline problem. NEDA (National Eating Disorders Association) has a helpline (1-800-931-2237), a crisis text line (text NEDA to 741741), and a screening tool at nationaleatingdisorders.org. Your campus counseling center is usually free with tuition and has clinicians trained in eating disorders. If you are having thoughts of self-harm, 988 (Suicide and Crisis Lifeline) covers acute risk — call or text 988 in the US. See binge eating disorder and weight loss for the BED-specific pathway and anorexia recovery and weight restoration for the recovery side.

Body image, comparison, and the campus environment

The college environment concentrates people your age in a small physical space with a heavy social-media overlay. Comparison is the mechanism, not the outcome. The 20 fittest people on your campus are the 20 you see at the rec center — you are seeing a selected sample, not a representative one, and Instagram compounds that selection.

Two evidence-anchored notes:

• Social-media comparison and body dissatisfaction. The research base on Instagram and body dissatisfaction in young women (and increasingly young men) is robust. Curated fitness content is a comparison trap even when the intent is inspiration. See weight loss and social media comparison for the specific unfollow-and-time-limit protocol.
• Body-image work is legitimate weight work. Body-image distress predicts disordered eating better than actual body weight. The weight loss and body image piece covers the acceptance-versus-change tension that is central to sustainable weight work at this age.

If body-image distress is interfering with daily function — you avoid the gym because you feel watched, you skip the beach or pool, you cannot look in mirrors, you diet to hide from photos — that is a signal to talk to the campus counseling center. And again, NEDA and 988 are there for the acute side.

The tuition-included resources most students under-use

Campus resources that are (usually) already paid for with tuition and worth using:

• Campus rec center. Weight room, cardio equipment, group fitness classes, sometimes a pool.
• Campus dietitian or nutritionist. Many student health centers have one on staff. Free or low-cost appointments.
• Campus counseling center. Trained clinicians for eating disorders, anxiety, depression, ADHD support. Free with tuition at most schools.
• Intramural and club sports. The social + movement combination is a two-birds-one-stone win.
• Group fitness classes. Yoga, HIIT, dance, spinning — usually included, sometimes with a small drop-in fee.
• Peer health-education programs. Some schools run peer nutrition or wellness programs run by trained undergraduates.
• Student health center. For thyroid panels, iron panels, birth-control counseling — see if your school covers labs.

If you cannot find these on your campus website, the health center or dean of students office is the first stop.

The realistic four-year plan

Rather than a 12-week freshman-fall crash, plan the college window as a four-year behavior-building project. That framing lines up with Racette 2005 (the ~2 lb per year continued drift finding) and produces the outcome you actually want — a set of habits you can hold at 22, 32, and 42, not a semester of restriction followed by a rebound.

• Freshman year: dining-hall plate-composition rule; alcohol pattern set; sleep floor established; use the campus rec center at least 1x/week.
• Sophomore year: if moving off the meal plan, learn 5 dorm-kitchen or apartment-kitchen recipes you actually like. Add a second rec-center day per week.
• Junior year: grocery-shopping and cooking pattern set for post-college life. One social eating night per week (a shared dinner or group meal you look forward to). Three rec-center days per week.
• Senior year: identify which patterns you’ll take with you into your first job. Interviews, resumes, and stress make senior year a high-risk gain window — protect the habits you built, don’t rebuild them at 23.

Frequently asked questions

Is the Freshman 15 actually real? It is directionally real but roughly a third the size of the myth. Vella-Zarb & Elgar 2009 (Journal of American College Health) meta-analyzed the first-year college weight-gain literature and found an average gain of about 3.5 to 4.5 lb across the freshman year — not 15. Vadeboncoeur 2015 (BMC Obesity) updated the meta-analysis across 32 studies and confirmed an average of roughly 3.4 lb. Racette 2005 (Journal of American College Health) followed a University of Missouri cohort across all four years and found gains kept accumulating at roughly 2 lb per year, so a total of about 9 lb across the four-year window is a more accurate framing than a single freshman-year hit. The number is not 15, but it is not zero, and the trajectory continues past freshman year — which is why the interventions in this article are written for a four-year, not a first-semester, window.

What actually causes weight gain in college? Four drivers do most of the work. First, the unlimited-portion dining-hall environment — Wansink 2007 (Obesity) documented how self-serve buffets and hidden portion norms push intake up without conscious awareness.

Fourth, the late-night delivery-app window — DoorDash and Uber Eats at 2 a.m. is a genuinely new environmental input in the last decade. Notice what is not on the list: “not enough gym time” and “metabolism.” Both are essentially non-factors at this age.

How do I not gain weight from the dining hall? Use the plate-composition rule: half the plate produce (leafy salad, roasted vegetables, cooked greens, fruit), a quarter of the plate protein (grilled chicken, fish, eggs, tofu, beans), and a quarter of the plate starch (rice, pasta, potato, bread). At the salad bar, dressing goes on the side — the 700-kcal “salad” (ranch, croutons, cheese, bacon bits, dried cranberries, sunflower seeds) is a real trap, not a stereotype.

How much does alcohol matter for weight in college? More than most students realize, but not for the reason usually cited. The calories add up (light beer ~100 kcal, regular beer ~150 kcal, 5 oz wine ~120 kcal, a mixed drink 200 to 400 kcal, White Claw ~100 kcal) — a 4-drink night is a real 600 to 1,200 kcal on top of your day. But the bigger driver is the disinhibition amplifier: Small 2013 (Journal of American College Health) documented how alcohol reliably increases late-night food intake beyond the drink calories themselves — the 1 a.m. pizza-and-cheese-fries order after the bar is the actual mechanism, not the beer itself. Two harm-reduction defaults that work for most students: cap drinking to two nights a week rather than aiming for abstinence, and pre-plan the drunk-food option (one slice of pizza plus water at 1 a.m. is a plan; a full order of everything is what happens without a plan).

Can I lose weight in a dorm with no kitchen? Yes, and you do not need to cancel your meal plan or buy a hot plate. Seven no-oven, mini-fridge-friendly protein staples cover most protein needs: Greek yogurt (17 g per 6 oz), cottage cheese (14 g per half cup), hard-boiled eggs sold pre-peeled (6 g each), string cheese (7 g per stick), beef or turkey jerky (10 g per oz), foil tuna pouches (17 g per pouch), and whey or plant protein shakes (20 to 25 g per scoop or bottle). Pair with pre-cut fruit, bagged salad kits, roasted chickpeas, or the fruit and pre-made salad options at the dining hall. Cost-per-gram-of-protein winners at 2026 pricing are usually eggs, cottage cheese, and jerky. Skip the giant Costco tub of cookies for the same reason it is a bad idea anywhere else — availability drives intake.
