list of off-limit foods. During the month-long elimination
period, no cheating is allowed.

you think about food, as well as your taste.

Life After Whole30: The Reintroduction Phase
Once you’ve successfully completed the Whole30 program, it’s
time to focus on step 2 — the reintroduction phase.
In this phase, certain foods will be slowly reintroduced to
evaluate how they make you feel in regard to your healthier
metabolism, digestive tract, immune system and relationship
The suggested way to reintroduce off-limit foods is to add back
only one food group at a time. For instance, milk can be
reintroduced on day 1.
You are then encouraged to return to the Whole30 diet and avoid
milk on days 2–4, while paying attention to any potential
If all goes well, a different food group can be reintroduced on
day 5, repeating the process.
Reintroducing only one food group at a time while keeping the
rest of the diet the same is promoted as a way to better
identify which foods cause negative symptoms, such as
bloating, skin breakouts or achy joints.
Once all food groups have been individually tested, those that
were well-tolerated can be added back into the diet.
Naturally, individuals are not required to reintroduce all
foods. In fact, they’re strongly encouraged to avoid
reintroducing foods that they do not miss.
Summary: After the initial 30 days, you may
slowly reintroduce off-limit foods to see how they affect
health and fit into your new eating pattern.

foods and a high intake of fresh
fruits and vegetables.
However, avoiding nutrient-rich foods like legumes, soy and
dairy may make it more difficult to meet all your daily
nutrient recommendations (1).
This may create negative health effects if the diet is
continued for more than 30 days.
In addition, although rigid rules can be a good way to reset
eating habits for some people, restrictive diets with no
allowance for indulgences are generally not sustainable over
Those contemplating following this diet in the long term are
encouraged to record their meals for a couple days in an online
diet journal such as Cronometer.
This can help ensure that daily nutrient recommendations
continue to be met.
Summary: The restrictive nature of the
Whole30 diet may make it difficult to meet daily nutrient
recommendations or sustain the diet in the long term.
Should You Try the Whole30 Diet?

help create the calorie deficit you need to shed some extra
However, unless the food choices you make on this diet become a
habit, the weight loss you experience may not be sustainable in
the long term (2).
Nevertheless, it is true that some people may unknowingly
suffer from food intolerances, which the diet’s reintroduction
phase can help identify (9).
Overall, this diet may be helpful if you want to completely
reset your eating habits.
But if you’re simply looking to improve your diet and overall
health, you’re better off trying a whole foods diet like
this one instead.
