    Before COFFEY, ROVNER, and EVANS, Circuit Judges.
  PER CURIAM. Norbert Skarbek seeks disability insurance
benefits, alleging that he is unable to work due to osteoar-
thritis in his knees. An ALJ found that although Skarbek
has a severe impairment and cannot perform his past rele-
vant work, he retains the capacity to perform work within

  Pursuant to Circuit Rule 53, this decision was originally issued
as an unpublished order. The court, upon request, now issues this
decision as a published opinion.

the national economy and is therefore not entitled to bene-
fits. The district court upheld that decision, and we affirm.
  At the time of his hearing, Skarbek was 51 years old with
a high school education. He is 6'1" tall and weighed 245
pounds. Skarbek has not worked since August 24, 2000,
when knee problems prevented him from bending and squat-
ting as required in his job as a construction laborer. Skarbek
had previously worked as an outdoor sign installer, as-
sembler, welder, repairman, and painter.
  In July 2000, because of pain in his knees, Skarbek saw
Dr. W.R. Yergler, an orthopedic specialist. Dr. Yergler wrote
that Skarbek’s knees were “not compatible with his job” be-
cause, while they could tolerate standing and walking, they
could not tolerate squatting and climbing. In October, Skarbek
was given an independent medical examination by Dr. Mark
Graham, a rehabilitation specialist. Dr. Graham noted that
Skarbek was overweight and recommended that Skarbek
take anti-inflammatory medication for his knees. Dr. Graham
found Skarbek “capable of gainful employment” and recom-
mended a restriction of no climbing, squatting or kneeling.
  Skarbek was also treated by his family physician, Dr.
Ralph Inanbit, for his knee problems, high blood pressure,
and other illnesses. Dr. Inanbit’s records show that Skarbek
was down to 204 pounds in May 1998, but gained weight af-
ter he stopped working. In a medical assessment on October
13, 2001, Dr. Inanbit wrote that Skarbek could sit, stand, or
walk for four hours without interruption, and could occa-
sionally lift up to 25 pounds. But nine days later, on
October 22, Dr. Inanbit altered his assessment when he
wrote a letter to Skarbek’s attorney stating that Skarbek
“can walk for only short distances, less than one-half block . . .
he also has difficulty with lifting, he can lift only five to ten
pounds and then develops severe pain.” He recommended
that “Skarbek be considered for disability” based on his
knee pain.
No. 03-3745                                                  3

  Two Social Security Administration (“SSA”) physicians,
Dr. J.V. Corcoran and Dr. W. Bastanagel, reviewed Skarbek’s
medical records, but did not examine him in person. Based
on their review of the records, both doctors concluded that
Skarbek could frequently lift 25 pounds and could stand,
walk, or sit for about six hours in an eight-hour workday.
They agreed that Skarbek should never kneel, crouch, or
crawl, and could only occasionally stoop or climb stairs.
They also noted that Skarbek’s body mass index (“BMI”)
was greater than 32, a score that registered him as obese.
   Skarbek filed for disability benefits in October 2000. The
SSA initially, and upon reconsideration, denied his claim.
Skarbek then appeared before an ALJ at a hearing, where
both he and a Vocational Expert (“VE”) testified. Skarbek
testified that he lived alone and could complete routine house-
hold chores, but when his knees were swollen, he could walk
or stand for only one hour and had to elevate his legs.
Skarbek testified that he could lift fifty pounds, mow his
small lawn if he took breaks, and drove. Skarbek also tes-
tified that for exercise he swam and rode a stationary bike
with no resistance.
  The ALJ applied the five-step analysis, see 20 C.F.R.
§ 404.1520, and found that Skarbek was not disabled. The
ALJ found that Skarbek had not engaged in any substantial
gainful activity since his alleged onset of disability and that
his knee problems constituted a severe impairment, but did
not meet or equal the level of severity of a listed impair-
ment. The ALJ found that Skarbek had the Residual
Functional Capacity (“RFC”) for a limited range of medium
work involving only occasional stooping, and no squatting,
climbing, kneeling, crouching, or crawling, or work that
requires being outside in wet weather. The ALJ evaluated
the medical evidence and credited the opinions of the spe-
cialists, Dr. Graham and Dr. Yergler, over that of Skarbek’s
treating physician, Dr. Inabnit, whose opinion the ALJ found
not well-supported by the medical evidence and inconsistent
4                                                  No. 03-3745

with his own progress notes. The ALJ also determined that
Skarbek’s testimony was not totally credible. Although the
ALJ found that Skarbek could not perform his past relevant
work, he was capable of performing “a significant range of
medium work,” which is defined as work involving lifting no
more than 50 pounds with frequent lifting or carrying of
objects up to 25 pounds. See 20 C.F.R. § 404.1567(c). The
ALJ, relying on the VE’s answer to his hypothetical ques-
tion, concluded that Skarbek could successfully adjust to
work that exists in significant numbers in the national
economy, including packager, inspector, and unarmed guard.
  The Appeals Council denied Skarbek’s request for review,
rendering the ALJ’s decision the Commissioner’s final de-
cision. In August 2002, the district court affirmed the
Commissioner’s final decision denying disability benefits,
finding that the ALJ’s decision was supported by substan-
tial evidence.
  This court will uphold the ALJ’s decision so long as it is
supported by substantial evidence in the record. 42 U.S.C.
§ 405(g); Gudgel v. Barnhart, 345 F.3d 467, 470 (7th Cir.
2003). “Evidence is ‘substantial’ if it is sufficient for a rea-
sonable person to accept as adequate to support the decision.”
Johansen v. Barnhart, 314 F.3d 283, 287 (7th Cir. 2002)
(internal quotations omitted). When reviewing the record,
this court may not re-weigh the evidence or substitute its
judgment for that of the ALJ. Lopez ex rel. Lopez v. Barnhart,
336 F.3d 535, 539 (7th Cir. 2003). An ALJ must articulate,
at least minimally, his analysis of the evidence so that this
court can follow his reasoning. Clifford v. Apfel, 227 F.3d
863, 870 (7th Cir. 2000).
  Skarbek first argues that the ALJ reached a flawed RFC
assessment by failing to give controlling weight, or at least
deference, to the opinion of his treating physician, Dr. Inanbit.
Skarbek argues that the ALJ overvalued the opinions of Dr.
Yergler and Dr. Graham, who saw Skarbek only once, and
No. 03-3745                                                  5

not as recently as Dr. Inanbit. As a result, Skarbek argues,
the ALJ erred in determining that he could perform
medium work, rather than crediting Dr. Inanbit’s opinion
that he was disabled.
  A treating physician’s opinion regarding the nature and
severity of a medical condition is entitled to controlling
weight if supported by the medical findings and consistent
with substantial evidence in the record. Gudgel, 345 F.3d at
470; see 20 C.F.R. § 404.1527(d)(2). An ALJ may discount a
treating physician’s medical opinion if it is inconsistent with
the opinion of a consulting physician, Dixon v. Massanari, 270
F.3d 1171, 1178 (7th Cir. 2001), or when the treating
physician’s opinion is internally inconsistent, Clifford, 227
F.3d at 871, as long as he “minimally articulate[s] his rea-
sons for crediting or rejecting evidence of disability,” id. at
870.
  Here, the ALJ provided an adequate explanation for giv-
ing more weight to Dr. Graham and Dr. Yergler’s opinions:
Dr. Inanbit’s opinion was not well-supported by medical
evidence. Dr. Inanbit indicated that Skarbek had only a
limited range of motion in his knees, but as the ALJ found,
this limitation was not supported by the X-rays or by Dr.
Inanbit’s progress notes. Further, in his letter nine days
later to Skarbek’s attorney, Dr. Inanbit did not identify med-
ical evidence that would support the changes he made in
assessing Skarbek’s limitations. Although the ALJ did not
discuss the internal inconsistencies between Dr. Inanbit’s
medical assessment and his letter to Skarbek’s attorney,
these inconsistencies would also support the ALJ’s decision
not to give controlling weight to Dr. Inanbit’s opinion. See
Clifford, 227 F.3d at 871. In contrast, the ALJ found Dr.
Graham and Dr. Yergler’s opinions consistent with the
medical evidence.
  Further, contrary to Skarbek’s assertion, the ALJ was not
required to recontact Dr. Inanbit for additional evidence or
6                                                No. 03-3745

to obtain medical expert testimony. An ALJ need recontact
medical sources only when the evidence received is inade-
quate to determine whether the claimant is disabled. See 20
C.F.R. § 404.1512(e). Here, the evidence was adequate for
the ALJ to find Skarbek not disabled, and the ALJ acted
within his discretion in deciding not to call a medical ex-
pert. See 20 C.F.R. § 404.1527(f)(2)(iii).
  Skarbek also argues that the ALJ erred by failing to con-
sider his weight in determining whether he was disabled.
See SSR 00-3p, (since superceded by SSR 02-1p without any
substantive changes). Social Security Ruling 00-3p requires
an ALJ to consider the effects of obesity at several points in
the five-step process. Id. at 5; see also Celaya v. Halter, 332
F.3d 1177, 1181-84 (9th Cir. 2003). At 6'1" and 245 pounds,
Skarbek has a BMI of 32.3, which the SSA recognizes as
Level 1 obesity, the lowest of three levels. Id. at 4. Skarbek
does not explain how his obesity would have affected the
ALJ’s five-step analysis. Rather, he suggests that the ALJ’s
failure to mention his obesity is reason enough to remand
the case.
  An ALJ is required to consider impairments a claimant
says he has, or about which the ALJ receives evidence. 20
C.F.R. § 404.1512(a). Although Skarbek did not specifically
claim obesity as an impairment (either in his disability ap-
plication or at his hearing), the references to his weight in
his medical records were likely sufficient to alert the ALJ to
the impairment. See Clifford, 227 F.3d at 873 (holding that
ALJ should have been alerted by “numerous references in the
record” to the claimant’s weight problem). Despite this, any
remand for explicit consideration of Skarbek’s obesity would
not affect the outcome of this case. See Keys v. Barnhart,
347 F.3d 990, 994-95 (7th Cir. 2003) (applying harmless
error review to ALJ’s determination). Notably, Skarbek does
not specify how his obesity further impaired his ability to
work, but speculates merely that his weight makes it more
difficult to stand and walk. Additionally, the ALJ adopted
No. 03-3745                                                 7

the limitations suggested by the specialists and reviewing
doctors, who were aware of Skarbek’s obesity. Thus, although
the ALJ did not explicitly consider Skarbek’s obesity, it was
factored indirectly into the ALJ’s decision as part of the
doctors’ opinions.
  Next, Skarbek argues that the ALJ erred in his credibility
determination by failing to follow SSR 96-7p, which lists
factors to be considered and requires an ALJ to articulate
his reasons for finding a claimant not credible. An ALJ is in
the best position to determine a witness’s truthfulness and
forthrightness; thus, this court will not overturn an ALJ’s
credibility determination unless it is “patently wrong.” E.g.,
Zurawski v. Halter, 245 F.3d 881, 887 (7th Cir. 2001) (inter-
nal quotations omitted). This court will affirm a credibility
determination as long as the ALJ gives specific reasons that
are supported by the record for his finding. Brindisi ex rel.
Brindisi v. Barnhart, 315 F.3d 783, 787 (7th Cir. 2003);
Zurawski, 245 F.3d at 887.
   The ALJ provided sufficient support for his finding that
Skarbek was not credible regarding his limitations. First,
the ALJ stated that Skarbek’s testimony of constant throb-
bing pain was not consistent with the findings of the spe-
cialists or with Skarbek’s medical records. Second, the ALJ
stated that Skarbek’s testimony regarding his daily activ-
ities—that, among other things, he drove, did laundry and
household chores, and was able to cut grass on occasion—
did not support a finding that he was totally disabled. The
ALJ found that Skarbek’s abilities and activities were more
consistent with the opinions of Dr. Yergler and Dr. Graham
than with his own testimony. The ALJ thus complied with
SSR 96-7p by providing specific reasons for his finding.
  Finally, Skarbek raises the entirely new argument that
the VE’s findings were not consistent with the Dictionary of
Occupational Titles (“DOT”) and that the ALJ erred by
failing to explain how the VE’s testimony was consistent
8                                               No. 03-3745

with Skarbek’s limitations. Because Skarbek did not raise
these arguments previously, he waived the opportunity to
raise them on appeal. Schoenfeld v. Apfel, 237 F.3d 788, 793
(7th Cir. 2001); Ehrhart v. Sec’y of Health and Human
Servs., 969 F.2d 534, 537 n.4 (7th Cir. 1992). In any event,
these arguments are meritless. The VE specifically testified
that his findings were consistent with the DOT. (Admin. R.
at 168.) And contrary to Skarbek’s assertions, the DOT clas-
sifications for unarmed guard and assembly packager are
consistent with Skarbek’s limitations in that the jobs do not
involve climbing, kneeling, stooping, crouching, or crawling.
See DOT §§ 372.667-034, 920.587-018. As a result, the ALJ
did not err by relying on the VE’s testimony.
  The ALJ’s decision to deny disability benefits was based on
substantial evidence. Therefore, the decision of the district
court is AFFIRMED.
