Protein is the thing
Your game plan starts here. On a GLP-1 or not, protein is the piece almost everyone gets wrong, and the one that changes how you actually feel day to day.
The cost of leaving gains on the table
Protein is not just a macro. It builds and repairs muscle, keeps you full longer, and helps your body function at its best.
Here is the play most people miss. On a GLP-1 like semaglutide or tirzepatide, your appetite drops and so does your intake, which means your body can start burning through muscle for fuel instead of fat. Studies have shown that up to 40 percent of the weight lost on these medications can come from lean muscle when protein intake is too low.
Hitting your protein goal is how you protect your strength and make sure what you are losing is fat, not the muscle you worked for.
The gap in your game. On average, adults eat only about 16 percent of their daily protein at breakfast and load the rest onto dinner. Your body can only use so much at once, so a protein-light morning is a miss you cannot make up at 8pm.
Eat protein first. Everything downstream gets easier.
Your target, in one multiplication
Multiply your target body weight in pounds by the multiplier for your goal.
Protect what you have
= daily protein (g)
Use your goal weight, not your current weight. This is what preserves muscle while you lose fat.
Goal weight 150 lbs × 0.8 = 120g a day
Build on top
= daily protein (g)
Higher end if you are lifting heavy. Lower end if you are just starting resistance training.
160 lbs × 1.0 = 160g a day
Hold your ground
= daily protein (g)
Enough to sustain muscle and keep your energy steady.
145 lbs × 0.7 = about 100g a day
Aim higher
= minimum daily protein (g)
Because appetite is suppressed, you are likely eating less overall. Protein has to be a priority at every meal.
Aim for 25 to 35g per meal
Spread it out
Spread your protein across 3 to 4 meals. Your body can only absorb and use so much at once, and research on evenly distributed intake supports that pattern over a skewed one. Front-loading it all at dinner does not count as a win.
One note. These targets sit at the higher end of general guidance, which is deliberate when appetite is suppressed. If you have kidney concerns, are pregnant, or are managing another condition, talk with your provider about the right number for you. If you are a Fitish patient, message your care team and we will help you land on it.
Ways to get there without trying harder
You do not need a new diet. You need a handful of swaps that add grams without adding effort.
In the kitchen
- Stir cottage cheese into scrambled eggs before cooking. Adds 14g, zero taste difference.
- Blend silken tofu into smoothies. Completely tasteless, adds 8g per half cup.
- Swap regular pasta for chickpea or lentil pasta. Nearly twice the protein per serving.
- Add unflavored protein powder to oatmeal, pancake mix, or muffin batter.
- Use Greek yogurt instead of sour cream in dips, tacos, and baked potatoes.
- Blend collagen peptides into your morning coffee for an effortless 10g.
Meal prep wins
- Buy a rotisserie chicken every Sunday and put it on everything all week.
- Hard-boil a dozen eggs Sunday night. Breakfast in under 60 seconds.
- Batch-cook lentils for soups, grain bowls, or tacos. Protein and fiber in one move.
- Pre-portion snack bags with jerky, string cheese, and pumpkin seeds so you never reach for chips.
Shop smarter
- Aim for at least 15g of protein per snack. It changes your cart fast.
- Bone broth over regular broth. Sip it hot or cook with it for a free 10g.
- Pick higher-protein bread, around 4 to 5g per slice.
- Keep edamame in the freezer. Five minutes, 8g of plant protein, done.
At every meal
- Eat your protein first, before the carbs and veggies.
- Add hemp seeds to anything. 10g per 3 tbsp with zero effort.
- Turkey roll-ups instead of crackers. Jerky instead of chips. Greek instead of regular.
- On a GLP-1 and not hungry? Reach for a shake or Greek yogurt rather than skipping the meal.
What hitting your mark unlocks
The research is consistent on the direction, even where the exact numbers vary person to person.
Steady through the afternoon, without the 3pm crash.
Less wrecked the day after a workout.
Studies in people eating at a deficit show adequate protein helps preserve muscle.
In one clinical study a higher-protein diet cut hunger ratings by roughly half compared with a lower-protein diet.
Protein supports collagen production, which shows up in how you look as well as how you feel.
Protein takes more energy to digest than carbs or fat, roughly 20 to 30 percent of its own calories versus 5 to 10 percent for carbs.
Shop protein first
Every item comes with its protein count per serving, so you can build your cart around protein and let everything else fill in around it. Aim for 2 to 3 sources from each category each week.

The things people ask us
Do I need protein powder to hit my number?
No. Powder is a shortcut, not a requirement. Most people get there on real food, and the grocery list above is built so you can. Powder earns its place on the days your appetite is low or you are short on time, which on a GLP-1 can be most days.
What if I am not hungry at all?
Reach for something drinkable rather than skipping the meal. A ready-to-drink shake or a cup of Greek yogurt gets you 17 to 30g without needing an appetite. Skipping compounds, because the grams you miss today do not carry over to tomorrow.
Is this only useful if I am on a GLP-1?
Not at all. On a GLP-1 protein becomes urgent because your intake drops. Off one it is still the difference between white-knuckling your afternoon and coasting through it. Same target math, same grocery list.
Can I eat too much protein?
For most healthy adults, intakes in the ranges above are well tolerated. If you have kidney concerns, are pregnant, or are managing another condition, this is worth a conversation with your provider rather than a guess from a webpage. Fitish patients can message their care team.
Does it matter when I eat it?
Yes, more than most people expect. Spreading protein across 3 to 4 meals beats loading it all at dinner, and research on even distribution supports that. Breakfast is where most people leave the biggest gap.
